3.11.10 Maintenance aging. When tested in accordance with 4.9.10, connectors shall show no visible

evidence of wear or degradation, which may degrade their ability to perform as specified. The connector

insertion loss shall be within the limits specified in 3.10.1.

3.11.11 Coupling forces. When specified (see 3.1) connectors shall be tested in accordance with

4.9.11. The maximum forces for coupling and uncoupling of the connectors shall be as specified (see

3.11.12 Coupling torques. When specified (see 3.1) connectors shall be tested in accordance with

4.9.12. The maximum torque for coupling and uncoupling of the connectors shall be as specified (see

3.11.13 Mating durability. When tested in accordance with 4.9.13, the connector shall show no defects

detrimental to the operation of the connector and shall have mating forces and coupling torques in

accordance with 3.11.11 and 3.11.12 respectively. The requirements of 3.10.1 shall be met before and

after the test.

3.11.14 Impact. When tested in accordance with 4.9.14, connectors shall show no evidence of broken,

loose, deformed or displaced parts, cracks, chips, or other damage, which would result in a degradation

of optical performance. Insertion loss shall not exceed the limits specified in 3.10.1.

3.11.15 Twist. When tested in accordance with 4.9.15, the cable/connector interface shall have no

damage detrimental to the operation of the cable or connector. The connector insertion loss shall not

exceed the limits specified in 3.10.1 before, during, and after the test.

3.11.16 Cable seal flexing. When tested in accordance with 4.9.16, connector strain relief mechanisms

shall prevent loss of environmental sealing or other damage, which may impair the connector operation.

The requirements of 3.10.1 shall be met before, during, and after the test.

3.11.17 Cable retention. When tested in accordance with 4.9.17, there shall be no evidence of cable

jacket damage, cable clamp failure, cable to connector seal damage, distortion or bending of metallic

connector parts, or cable disengagement from the clamp. The minimum cable to connector pull-out

strength shall be 400 pounds. The requirements of 3.10.1 shall be met before, during, and after the test.

3.11.18 Crush resistance. When tested in accordance with 4.9.18, connectors shall show no broken

parts, no degradation of mating-unmating, or no damage to the seals. The connector shall meet the

requirements of 3.10.4 before and after the test and the requirements of 3.10.1 before, during, and after

the test.

3.11.19 External bending moment. When tested in accordance with 4.9.19, connectors shall show no

evidence of damage detrimental to their normal operation nor shall there be any interruption of their ability

to perform as specified (see 3.1). The requirements of 3.10.1 shall be met before, during, and after the

test.

3.11.20 Temperature life. When tested in accordance with 4.9.20, connectors subjected to the

specified accelerated aging exposures shall not exhibit visual evidence of dimensional change, opening

of seals, cracking or crazing of components or finishes, identification marking impairment, fusion or

seizure of mating parts, leakage or waterproofing compounds, or other effects detrimental to connector

operation. No evidence of adhesive degradation shall be present. The requirements of 3.10.1 shall be

met before and after the test.
