MIL-STD-2042-6B(SH)

1.  SCOPE.

METHOD 6E1

CABLE TOPOLOGY END-TO-END ATTENUATION TEST

1.1  Scope.  This method describes a procedure for performing a cable topology end-to-end attenuation test to ensure that the FOCT losses are within acceptable limits.

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 are razor sharp.  Wash your hands after handling bare 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.  FOCT 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.  FOCT links terminated in connectors do not require the performance of Procedure I.  FOCT links terminated in splice ferrules require the completion of a temporary splice in order to test for cable topology end-to-end attenuation.  The splice procedure description herein is 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 6E1-I shall be used to perform this procedure.

TABLE 6E1-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.
