MIL-STD-2042-3B(SH)

1.  SCOPE.

METHOD 3B1

CABLE PENETRATIONS VIA MCP'S

1.1  Scope.  This method identifies MCP insert block sizes used to pass optical fiber cables through decks and bulkheads. The methods for installation of the MCP

and insert blocks is the same as those specified for electrical cables in MIL-STD-

2003-3. These installation methods are not repeated in this standard practice but

they are identified in paragraph 5 in this part of this standard practice.

2.  REQUIRED EQUIPMENT AND MATERIALS. (Not applicable.)

3.  PROCEDURES.

3.1  Safety summary. The following safety precautions shall be observed during the passing of optical fiber cables through the installed MCP's.

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

b.        Do not touch the ends of bare fibers as they may be razor sharp.  Wash your hands thoroughly 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.

e.        Never look into the end of a BOF tube.  Always wear approved safety glasses when handling BOF tubes that may be connected to a pressure source.

3.2  Procedure.

Step 1 - Select MCP insert blocks from those shown in table 3B1-I.
