1. SCOPE.
METHOD 6D1
CABLE CONTINUITY TEST
1.1 Scope. This method describes a procedure for performing a optical fiber cable continuity test on conventional or BOF cables with or without connectors or terminations of any type.
2. REQUIRED EQUIPMENT AND MATERIALS.
2.1 The equipment and materials in table 6D1-I shall be used to perform this procedure.
TABLE 6D1-I. Equipment and materials.
Description |
Quantity |
Safety glasses |
1 |
Alcohol bottle with alcohol/2-propanol (sealable type) |
As required |
Wipes (NAVSEA DWG 6872811-18 or equal) |
As required |
Canned air or compressed air |
As required |
Flashlight or high intensity light source |
1 |
Bare fiber adapter |
As required |
3. PROCEDURE.
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 ends of the fibers as they may be 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.
Step 1 - Establish communications, if required, using available communication equipment.
Step 2 - Using a wipe dampened with alcohol, clean the fibers on both ends of the optical fiber cable and blow them dry with air.
Step 3 - Using a flashlight or equivalent, shine light in each fiber and verify that light is present at the opposite end.
NOTE: For continuity testing of single mode fiber, a high intensity light source specifically for single mode continuity testing should be used.
NOTE: A bare fiber adapter may be used to optimize the connection between the flashlight and unterminated optical fibers.
