Page 9 of 24 3 Testing 3.1 General The construction and configuration of test samples shall be as described in the test plan agreed between Tyco Electronics and the customer. For internal qualification or requalification the number of samples being tested shall be depending on the object and the purpose of the test programme. For the optical tests minimum 1 circuit, containing minimum 10 fusion splices, shall be built in one sample. All installations shall be performed according to Tyco Electronics standard installation instructions and at room temperature, unless otherwise stated. If relevant for the test, samples shall be installed with cables. If it is required to use cables with lower performance capabilities, the test parameters will need to be appropriately modified. Tightness test samples shall be installed over unspliced optical cable. The cable ends shall be capped. Test samples shall include both maximum and minimum cable diameters as specified in the applicable installation instructions. It is not necessary to use all cable ports. For test pressure access, a valve shall be installed in the closure body or on cable caps. Unless specified otherwise, internal pressurization is achieved with an air supply held to ± 2 kpa of the specified value. Testing is at room temperature 10 unless otherwise specified. When tests are specified at temperatures other than ambient, the samples shall be preconditioned for a period of at least 4 hours at those temperatures. Pressure measurements before and after the test shall be carried out with the same pressure measurement equipment and at the same atmospheric conditions (temperature and pressure). When a difference is observed in atmospheric conditions, the pressure shall be calculated with the law p.v/t=cte. 10 Standard laboratory conditions of (+23 ± 3)ºC

Page 10 of 24 3.2 Test procedures 3.2.1 Appearance This test is included to ensure that no obvious defects are present that would affect product performance. Testing shall be performed in accordance with IEC 61300-3-1. The closure system and components shall be inspected for flaws, defects, pinholes, cracks or inclusions visible to the naked eye. 3.2.2 Axial tension This test is designed to simulate cable/closure manipulation. It specifically addresses seal performance. Testing shall be performed in accordance with IEC 61300-2-4. Testing shall be done at -15 C and +45 C. Samples shall be conditioned at -15 C or +45 C whilst pressurized internally at 40 kpa regulated. After conditioning, the pressure supply shall be disconnected in such a way that an internal pressure of 40 kpa remains inside the closure. The internal pressure shall be measured and recorded (see page 15). The closure shall be clamped, and a force shall be applied to each of the extending cables individually for a period of one hour. The force per cable shall be calculated according to the equation: D (cable outer diameter in mm)/45mm x 1000 N (maximum 1000 N). After completion of the test, internal pressure loss shall be checked (page 15) and samples shall be conditioned at room temperature. After visual inspection, the samples shall be subjected to the tightness test as described on page 20. After the test the permanent displacement of the cable elements in the cable attachment shall be smaller than 3 mm.

Page 11 of 24 3.2.3 Change in attenuation This is the criterion test for optical measurements during and after the test. The value quoted assumes the use of a stable qualified splice/protector, well installed. Testing shall be performed in accordance with IEC 61300-3-3. This is defined as a measured attenuation that is exhibited by stable transmission measurements taken before, during and after a test. The optical power shall be monitored using an optical source and a detector operating at 1310 nm, 1550 nm and 1625 nm. The preferred test set-up is shown below: Temperature Transducer Climatic Test Chamber Switch 1 Switch 2 and 3 Detector Source Test sample OTDR Reference IEEE 488 Interface bus Controller Source: 1310 nm ± 20 nm, 1550 nm ± 20 nm and 1625 ± 25 nm. Switch: Repeatability better than 0.04 db. The in- and outgoing fibers of each circuit are spliced onto the connection fibers of the equipment. Splices shall be made using good-quality fusion splices. During and after the test the optical power in each circuit shall be measured with the light source and detector at all specified wavelengths. A change of more than 0.2 db at 1310 nm and 1550 nm per incoming fiber during the test from the initial value constitutes a failure. A change of more than 0.5 db at 1625 nm per incoming fiber during the test from the initial value constitutes a failure. A change of more than 0.1 db at 1310 mm, 1550 nm and 1625 nm per incoming fiber after the test from the initial value constitutes a failure. Note: The above-mentioned loss criteria are per incoming fiber. Since one circuit can contain several incoming fibers, it is possible that the total circuit generates higher losses. In this case the loss contribution per incoming fiber needs to be checked. This can be done by OTDR or by reducing the number of incoming fibers per circuit.

Page 12 of 24 3.2.4 Flexure (tightness evaluation) This test simulates cable/closure manipulation and focuses on cable seal performance. Testing shall be performed in accordance with IEC 61300-2-37. Testing shall be done at -15 C and +45 C. Samples shall be conditioned at -15 C or +45 C whilst pressurized internally at 40 kpa regulated. After conditioning, the pressure supply shall be disconnected in such a way that an internal pressure of 40 kpa remains inside the closure. The internal pressure shall be measured and recorded (see page 15). The closure system shall be clamped on a smooth, flat, horizontal surface. Each cable shall be clamped in turn at 400 mm from the end of the closure. Cables shall be bent individually to an angle of 30 (or a maximum force application of 500 N) each side of neutral in the same plane. Each bending operation shall be held for 5 minutes. A cable shall then be returned to its original position and the procedure repeated in the opposite direction. The procedure shall be repeated with each cable protruding from the closure system. After 5 cycles on each cable, internal pressure loss shall be checked (page 15) and samples shall be conditioned at room temperature. After conditioning, specimens shall be examined with the unaided eye for damage that would impair product functionality (Appearance, page 10). After visual inspection, the samples shall be subjected to the tightness test as described on page 20.

Page 13 of 24 3.2.5 Flexure (optical evaluation) This test simulates cable/closure manipulation and focuses on optical system performance. Movement of the cable can cause fiber movement in the cable to organizer transition inside the closure. Testing shall be performed in accordance with IEC 61300-2-37. The optical test sample shall be built as described on page 14. Drop cable In Fibers Drop cable Track Joint Looped Cable External Node Out The active circuit of the test sample shall be connected to the optical test equipment as described on page 16. The closure system shall be clamped on a smooth, flat, horizontal surface. Each cable shall be clamped in turn at 400 mm from the end of the closure.

A cable shall then be returned to its original position and the procedure repeated in the opposite direction. The procedure shall be repeated with each cable protruding from the closure system. Residual loss shall be checked as described on page 16. After completion of the test specimens shall be examined with the unaided eye for damage that would impair product functionality (Appearance, page 10). 3.2.6 Impact This test is included to cover the effect of falling objects (by accident), e.g. tools, etc. on the closure. Testing shall be performed in accordance with IEC 61300-2-12, Method B. Testing shall be done at -15 C and +45 C. Samples shall be conditioned at -15 C or +45 C whilst pressurized internally at 40 kpa regulated. After conditioning, the pressure supply shall be disconnected in such a way that an internal pressure of 40 kpa remains inside the closure. The internal pressure shall be measured and recorded (see page 15). A sample shall be placed on a smooth, flat, horizontal surface with its longitudinal axis parallel to it. A steel ball weighing 1 kg shall be suspended at a height of 1 meter above the centre of the test specimen then allowed to fall under the influence of gravity. After the test, internal pressure loss shall be checked (page 15) and samples shall be conditioned at room temperature. After conditioning, specimens shall be examined with the unaided eye for damage that would impair product functionality (Appearance, page 10). After visual inspection, the samples shall be subjected to the tightness test as described on page 20.

Page 14 of 24 3.2.7 Installation of closure (optical evaluation) Checks the influence on the optical performance of a fiber optic channel when a window cut is made and installed in an EN. An optical sample is prepared as follows: In Fibers Drop cable Track Joint Looped Cable Out The extremities of a 50 meter looped cable (minimum 24 fibers) are brought into the closure (Track Joint). In the Track Joint (TJ) the fibers from one cable end are spliced to the fibers at the other cable end in such a way that light will sequentially flow through 9 selected fibers. Splices shall be made by using good-quality fusion splices. The fibers of a Drop Cable are spliced to the above-mentioned circuit to make an external connection to a light source and an optical power meter. The active circuit contains 10 fusion splices in the TJ closure. The remaining dark fibers are stored inside the tray. The optical circuit of the test sample is connected to the test equipment as described on page 15 and the optical power is recorded. The equipment will not be disconnected during the following installation test. In the middle of the cable loop a window cut will be made. The uncut looped fibers are brought into the External Node (EN) closure. Drop cable In Fibers Drop cable Track Joint Looped Cable External Node Out In the EN closure the non-active fibers of the drop cable are routed randomly in between these active uncut fibers (will be used during reconfiguration test). After the installation of the EN node, the optical power from the circuit is measured again and compared with the initial values. The change in optical signal shall meet the requirements as described on page 16.

Page 15 of 24 3.2.8 Pressure loss during test This is the criterion test for the tightness of a product during the test. The value quoted assumes the difference between 2 pressure measurements made within 12 hours. Testing shall be performed in accordance with IEC 61300-2-38, Method B with pressure losses being calculated from measurements taken before and after a test with: the feeder line removed, using the same pressure measurement equipment, and at equal atmospheric conditions (temperature and pressure). The pressure test equipment shall have a resolution of 0.1 kpa. The maximum time between the 2 measurements shall be 12 hrs (to minimize the changes in atmospheric conditions). A pressure loss of more than 2 kpa will constitute a failure. 3.2.9 Reconfiguration This is the criterion test to check the influence on the optical signal transmission of active circuits after doing typical handling operations that could be performed by the crafts personnel on the product. Testing shall be in accordance with IEC 61300-2-33. The optical test samples shall be built as described on page 14.

The following sequence is carried out on the External Node (EN) closure: Unroll the cable loop. Rotate the closure in such a way that a torsion of -90 and +90 is created in the cables. Move the closure in such a way that the cables are bent over -30 and +30 at the cable ports of the closure. Mount the closure on an installation table and open the closure. Select a non-active fiber of the looped cable and splice it to the fibers of the drop cable. Store the fibers in the tray. Close the closure. Coil up the cable respecting the minimum allowed bending diameter of the cable. The optical signal shall be measured after the test. The residual loss requirement (see page 16) shall be met.

Temperature cycling test shall be according to IEC 61300-2-22. Samples for optical evaluation are closed but not pressurized. Samples shall be supported in racks during testing in such a way that they are thermally isolated, and there shall be free circulation of air both between specimens and between the specimens and the chamber surfaces. They shall be subjected to 20 cycles defined as follows: Time Temperature or range 2 hr -30 C to +60 C 4 hr +60 C 2 hr +60 C to -30 C 4 hr -30 C The change in attenuation during and after the test is checked for each circuit as described on page 11. After completion of the test, specimens shall be examined with the unaided eye for damage that would impair product functionality.

Page 20 of 24 3.2.19 Tightness This is the criterion test to check the integrity of the seals both after installation and after mechanical or environmental testing. Testing shall be performed in accordance with IEC 61300-2-38, Method A (and IEC 60068-2-17 Test Qc). The tightness of installed closures shall be checked by pressurizing to 40 kpa for a period of 15 minutes while immersed just below the surface of a water bath at room temperature. A sample shall be considered tight if there is no continuous stream of air bubbles escaping from it. 3.2.20 Torsion (tightness evaluation) This test simulates cable/closure manipulation and focuses on the performance of the seals of the product. Testing shall be performed in accordance with IEC 61300-2-5. Testing shall be done at -15 C and +45 C. Samples shall be conditioned at -15 C or +45 C while pressurized internally at 40 kpa regulated. After conditioning, the pressure supply will be disconnected in such a way that an internal pressure of 40 kpa remains inside the closure. The internal pressure shall be measured and recorded (see page 15). Each extending cable shall in turn be clamped rigidly at a distance of 400 mm from the closure base. The closure system shall be axially rotated, with the degree of turn restricted to whichever of the following limits is reached first: a torque of 50 Nm a rotation angle of 90 degrees It shall be retained in that position for a period of 5 minutes, then be returned to its original position and the procedure repeated in the opposite direction. After 5 cycles on each cable, internal pressure loss shall be checked (page 15) and samples shall be conditioned at room temperature. After conditioning, specimens shall be examined with the unaided eye for damage that would impair product functionality (Appearance, page 10). After visual inspection, the samples shall be subjected to the tightness test as described on page 20.

Page 21 of 24 3.2.21 Torsion (optical evaluation) This test simulates cable/closure manipulation and focuses on optical system performance. Torsion of the cable can cause fiber movement in the cable to organizer transition inside the closure. Testing shall be performed in accordance with IEC 61300-2-5. The optical test samples shall be built as described on page 14. The active circuit will be connected to the optical test equipment as described on page 16. The closure systems shall be clamped on a smooth, flat, horizontal surface. Each extending cable shall in turn be clamped rigidly at a distance of 400 mm from the closure end. The closure system shall be axially rotated, with the degree of turn restricted to whichever of the following limits is reached first: a torque of 50 Nm a rotation angle of 90 degrees It shall be retained in that position for a period of 5 minutes, then be returned to its original position and the procedure shall be repeated in the opposite direction. This will be repeated for each cable, in total 5 cycles per cable. The residual loss shall be checked as described on page 16. After completion of the test specimens shall be examined with the unaided eye for damage that would impair product functionality (page 10). 3.2.22 Vibration (tightness evaluation) This test simulates cable movement in the ports and tests the performance of the seals. The conditions relate to vibration caused by passing traffic. Testing shall be in accordance with IEC 61300-2-1 (and IEC 60068-2-6, Test Fc). Samples shall be pressurized internally at 40 kpa regulated. The closure shall be mounted horizontally on a vibration bank, the cables shall be clamped at a distance of 500 mm from the closure end. The closure shall be subjected to a vibration test with the following parameters: Parameter Frequency: Cycle: Amplitude: Duration: Value (10 ± 1) Hz Sinusoidal 3 mm 10 days After testing, specimens shall be examined with the naked eye (appearance page 10) and then subjected to the tightness test described on page 20.

Page 22 of 24 3.2.23 Vibration (optical evaluation) This vibration test highlights possible problems caused by resonance effects. The effect on fiber and splice storage is checked. The conditions relate to vibration caused by passing traffic. Testing shall be in accordance with IEC 61300-2-1. The optical test samples shall be built as described on page 14. The active circuit will be connected to optical test equipment as described on page 16. The closure shall be mounted on a vibration bank and shall be subjected to a sweep range of 5-500 Hz at 1 octave/minute with the following parameters: Parameter Value Crossover frequency: 9 Hz Amplitude below 9 Hz: 3.5 mm Acceleration above 9 Hz: 10 m/s² (~ 1 g) The test shall be repeated for each of 3 mutually perpendicular axes, 10 cycles per axis. Residual loss shall be checked after the test as described on page 16. After completion of the test specimens shall be examined with the unaided eye for damage that would impair product functionality (page 10). 3.2.24 Waterhead This test is included to ensure that no obvious defects are present that would affect product performance when the product is immersed in water. Testing shall be according to IEC 61300-2-23, Method 2. The sample shall be sealed without any overpressure at room temperature. The sample is then placed in a sealed water tank. The water pressure inside the tank is brought to an equivalent of a 5-meter water column. After 7 days of immersion the sample is checked for any water ingress.

The supplier may utilize his own or other testing and inspection facilities acceptable to the buyer. 4.2 Qualification conformance For the purposes of internal qualification, the program shall consist of examinations and tests to determine conformance with the requirements of this specification. It shall be performed once, on introduction of the product. Subsequent design changes shall be partially or fully re-qualified depending upon their area of impact in the context of product functionality. For qualification testing to this specification for individual customers, the tests and sample quantities shall be as agreed between Tyco Electronics and the customer. Regular requalification testing shall be performed as defined by the Quality Department. 4.3 Manufacturing follow-up 4.3.1 Tyco manufacturing processes Manufacturing is an integral part of the overall Quality System of the Division 11. Customers are encouraged to audit not only manufacturing, but also other departments. Statistically based in-process control is practiced on all production lines where appropriate, and is conducted on all parameters that govern end-product functionality and performance. The frequency of such control and follow-up is evaluated during capability studies on new equipment and shop floor implementation of the results is determined by the Quality Department. In addition, the information is documented and controlled in the computerized manufacturing specification system. 4.3.2 Sourced Components All suppliers of materials, components or systems manufactured outside the Tyco Electronics facilities are included in the Vendor evaluation/follow-up system defined in TEL 2006/1. As a consequence of this, Tyco Electronics audits relevant suppliers on a regular basis in order to ensure conformance to TQM and specification requirements. Suppliers who do not reach the minimum level of approval are given help to improve their systems. If a supplier has not yet reached this minimum level, but is making adequate progress, outgoing controls at the supplier or incoming controls will be considered, as appropriate, by Tyco Electronics. 11 As managed by the Telecom Outside Plant & Netconnect Business Systems Manual TEL1001 and Quality Procedures TEL 20XX.
