1.  SCOPE.

METHOD 6C1

CABLE ASSEMBLY LINK LOSS TEST

1.1  Scope.  This method describes procedures for performing a cable assembly link loss test on optical fiber cables that have connectors or other terminations installed on both ends.

2.  REQUIRED EQUIPMENT AND MATERIALS.

2.1  The equipment and materials in the tables located in the applicable sections of this method shall be used to perform these procedures.

3.  PROCEDURES.

3.1  Safety summary.  The following safety precautions shall be observed:

a.   Safety glasses shall be worn when handling bare fibers.

b.        Do not touch the end of the fibers as they may be razor sharp.  Wash your hands after handling fiber.

c.   Observe warnings and cautions on equipment and materials.

d.        When visually inspecting an optical fiber, never stare into the end of a fiber connected to a laser source or LED.

3.2  Procedure I.  Cable assembly preparation for test.   This procedure is performed in series with Procedure II.  Refer to section 3.3 to determine when this procedure is to be applied.  Optical fiber cable assemblies terminated in connectors do not require the performance of this procedure.  Optical fiber cable assemblies terminated in splice ferrules require the completion of a temporary splice in order to test for link loss.  The splice procedures herein are abbreviated; a more

detailed description is given in Method 2D1 in Part 2 of this standard practice.

3.2.1  The equipment and materials in table 6C1-I shall be used to perform this procedure.

TABLE 6C1-I.  Equipment and materials.

NOTE:        During handling, the optical fiber cable shall be protected from kinks, twists, crushing and sharp bends. See Part 1 of this standard practice for more detailed optical fiber cable handling procedures.
