METHOD 6G1
HEAVY DUTY CONNECTOR MECHANICAL PULL TEST
1. SCOPE.
1.1 Scope. This method describes procedures for performing a mechanical pull test on the cable strain relief of heavy-duty connectors. The performance of this method is required only when specified by the contract.
2. REQUIRED EQUIPMENT AND MATERIALS.
2.1 The equipment and materials in table 6G1-I shall be used to perform this procedure.
TABLE 6G1-I. Equipment and materials.
Description |
Quantity |
Connector clamp |
1 |
Cable pulling device |
1 |
Strain gauge (with accuracy of +/- 5 percent) |
1 |
NOTE: The cable pulling device should not introduce any permanent deformation into the optical fiber cable jacket.
3. PROCEDURES.
3.1 Safety summary. The following safety precautions shall be observed:
a. Observe warnings and cautions on equipment and materials.
b. When visually inspecting an optical fiber, never stare into the end of a fiber connected to a laser source or LED.
3.2 Procedure.
Step 1 - Attach the strain gauge between a fixed object and the connector clamp.
Step 2 - Attach the heavy-duty connector to the connector clamp.
Step 3 - Attach the cable pulling device to the optical fiber cable.
Step 4 - Pull on the optical fiber cable assembly with a force of 444 Newtons
(100 lbs) for one minute.
Step 5 - Disconnect the cable pulling device and the connector clamp from the optical fiber cable assembly.
Step 6 - Visually inspect the connector/cable interface for cable pullout and deformation of the optical fiber cable jacket. Optical fiber cable assemblies that show these defects shall be rejected.
