2 Page 2 of 26 1 Product description The FOSC 450 base and dome are made from an impact resistant thermoplastic. Base to dome sealing is achieved using a clamp and O-ring system. Cable ports are sealed using a wrap-around gel block with a pre-installed gel profile with six ports, each capable of accommodating cables in the 9-25 mm diameter range. This block can be opened and closed repeatedly without the need to remove or replace the gel. The gel block permits the gradual addition of cables without disturbing cables installed earlier. A tray support structure allows the installation of mass splicing trays for single fiber or ribbon fiber. All the splicing trays are hinged at the support so that any fiber can be accessed without: disturbing fiber on other trays, kinking buffer tubes, introducing losses. Storage baskets for uncut fibers are available. Cable strain relief units provide the strength member fixation and cable jacket gripping. The closure is re-enterable and re-usable. Optional extras include an electrical feed-through and a pressure access valve.

9 Page 9 of 26 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 dome or 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 9 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 according to the relationship: p.v/t=cte. 3.2 Conversion factors C = ( F-32)/1.8 F = ( C x 1.8) cm² in² 1 kg lb 1 kpa psi 1 m ft 1 mm in 1 N lb 1 Nm 0.74 lbf. ft 9 Standard laboratory conditions of (+23 ± 3)ºC

10 Page 10 of Test procedures 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 The closure system and components shall be inspected for flaws, defects, pinholes, cracks or inclusions visible to the naked eye Axial tension This test is designed to simulate cable/closure manipulation. It specifically addresses seal performance. Testing shall be performed in accordance with IEC Samples shall be pressurized internally at 40 kpa at room temperature and sealed and measured (page 17) prior to testing. 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 shall be checked (page 17) again and specimens shall be subjected to the tightness test described on page 21. After the test the permanent displacement of the cable elements in the cable attachment shall be smaller than 3 mm.

11 Page 11 of 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 This is defined as a measured attenuation which 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.

12 Page 12 of Flexure (tightness evaluation) This test simulates cable/closure manipulation and focuses on cable seal performance. Testing shall be performed in accordance with IEC 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 17). 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 base. 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 17) 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 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 The optical test sample shall be built as described on page 14. The active circuit of the test sample shall be connected to the optical test equipment as described on page 11. 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 base. 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. The change in attenuation after the test (Residual loss) shall be checked 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 (appearance, page 10).

The internal pressure shall be measured and recorded (see page 17). 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 2 meter above the centre of the test specimen then allowed to fall under the influence of gravity. The test shall be repeated by rotating the closure along its major axis over 90, 180 and 270. After the test, internal pressure loss shall be checked (page 17) 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 21.

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 17). 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 No tensile load is to be applied. 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 17) 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 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 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 11. 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 No tensile load is to be applied. 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 change in attenuation after the test (Residual loss) shall be checked 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 10).

23 Page 23 of 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 (and IEC , 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 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 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 11. The closure shall be mounted on a vibration bank and shall be subjected to a sweep range of 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. The change in attenuation after the test (Residual loss) shall be checked 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 10) 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 , Method 2. The sample shall be sealed without any overpressure at room temperature. The sample is then placed in a sealed water tank, with no wetting agent added. 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 (Procedure K3014/001). 4.3 Manufacturing follow-up Kessel-Lo Components Manufacturing in Kessel-Lo, Belgium, is an integral part of the overall Quality System of the Division 10. 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 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 2006/2. 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. 10 As managed by the Telecom Outside Plant Business Systems Manual TEL1001 and Quality Procedures TEL 20XX and TEL K30XX.
