MIL-STD-2042-1B(SH)
4.1.9.2 Heavy-duty connector designation tag. Cables that terminate in a heavy-duty connector shall have a tag placed on the cable next to the connector designating the jack to which the connector is to be attached.
4.1.10 Cable repair (see 3.12). Damage to the outermost jacket of conventional optical fiber cable and BOF cable shall be repaired according to procedures specified herein (see 5.2). Conventional optical fiber cable with damage extending beyond the cable outer jacket to the Kevlar strength members or to the OFCC outer jacket shall be replaced. BOF cables with damage extending beyond the cable outer jacket to the Kevlar strength members or to the BOF tubes may be cut to remove the damaged section and spliced according to the procedures specified herein (see
5.3).
4.1.11 BOF cable splicing. BOF cables may be installed into the ship in a modular fashion and joined to form single continuous cables. BOF cables to be joined to form a single continuous cable shall be spliced according to the procedures specified herein (see 5.3).
4.1.12 BOF cable furcation. Multiple-tube BOF cables may be furcated into multiple BOF single tube cables. If a multiple-tube BOF cable is identified for furcation to several BOF single tube cables, the use of a tube routing box instead of a BOF cable furcation should be considered. Multiple-tube BOF cables shall be furcated according to the procedures specified herein (see 5.4).
4.2 Safety precautions. The following safety precautions apply:
a. Observe all written safety precautions given in the methods of this standard practice.
b. Observe all warning signs on equipment and materials.
c. The classification of a laser is based on the ability of the optical beam to cause damage to the eye. Under normal operating conditions, an optical fiber communication system (OFCS) is inherently an eye safe system; but, when an optical fiber connection is broken and optical viewing instruments are used, it is possible that hazardous energy can enter the eye. For
this reason four service group hazard classes have been devised to
indicate the degree of hazard and required hazard control measures. Refer
to ANSI Z136.2 for a full technical definition. The following laser
safety precautions shall apply:
(1) Ensure personnel are familiar with the laser degree of hazard and the required control measures.
(2) Light generated by light emitting diodes (LED's) and laser diodes may not be visible but may still be hazardous to the unprotected eye. Never stare into the end of an optical fiber connected to an LED or laser diode and do not stare into broken, severed or disconnected optical cables.
(3) Do not view the primary beam or a specular reflection from an OFCS with an optical microscope, eye loupe or other viewing instrument. The instrument may create a hazard due to its light gathering capability.
d. Safety glasses shall be worn when handling bare fibers. Always handle cable carefully to avoid personal injury. The ends of optical fibers may be extremely sharp and can lacerate or penetrate the skin or cause permanent eye damage if touched to the eye. If the fiber penetrates the skin, it most likely will break off, in which case the extraction of the fiber should be performed by trained medical personnel to prevent further complications.
