MIL-STD-2042-6B(SH)
a. a device with an ST compatible connector on one end and a holding mechanism for stripped fiber on the other end
b. a single fiber cable with an ST compatible connector on one end and a temporary splice which mates to the stripped fiber on the other end
c. an unused ST compatible connector in which the stripped optical fiber is placed
4.3 Test procedures. The following paragraphs discuss test procedures in general terms only. Detailed, step-by-step procedures are presented in section 5.
4.3.1 Visual inspections. Visual inspections for mechanical damage are accomplished with the naked eye without using a magnifier.
4.3.2 Cable continuity test. The optical fiber cable continuity test is a simple test to verify that there is no major damage to or breakage of a fiber. For multimode fiber, this test can be accomplished using any portable light source, such as a flashlight. For single mode fiber, a high intensity light source intended for optical fiber continuity measurements should be used.
4.3.3 BOF Ball bearing (BB) test. The BB test is a simple test to verify that there are no major obstructions within the BOF tubes in a BOF cable. This test is performed using a ball bearing with diameter of 4.5 or 5 mm and a source of pressurized air.
4.3.4 BOF pressurization test. The BOF pressurization test is a simple test to verify that there are no major tears or holes in the BOF tubes and that concatenated BOF tubes are properly coupled together. This test is performed using a source of pressurized air and a pressure gauge.
4.3.5 BOF tube seal verification test. The BOF tube seal verification test is used to verify that each unused BOF tube path is properly end sealed and that each used BOF path is properly terminated. This test is performed using a source of pressurized air and a pressure gauge. The BOF tube seal verification test may be omitted for BOF tube paths that are installed entirely above the ship's V-line.
4.3.6 Cable attenuation test. The cable attenuation test quantifies the attenuation of an optical signal over a particular cable length. The attenuation test is intended to be used for testing cables that have no terminations installed, or cables with terminations on only one end, and is performed using an OTDR.
4.3.7 Cable assembly link loss test. The cable assembly link loss test is used to measure the optical losses associated with connectors and splices in an optical link; and to demonstrate that the end-to-end attenuation of an optical fiber cable assembly is within acceptable limits. The link loss test shall be performed using an optical power meter and stabilized light source, or an OLTS.
4.3.8 Cable topology end-to-end attenuation test. The cable topology end-to- end attenuation test is used to measure the optical loss over a series of concatenated optical links (see 3.8). Typically, this test is performed after interconnection of the FOCT local and trunk cables, and measures the optical loss from one local cable equipment interface to the other. The end-to-end attenuation test shall be performed using an optical power meter and stabilized light source, or an OLTS.
4.3.9 Optical return loss test. The optical return loss test is used to measure the relative amount of optical power that would be reflected back into a link transmitter by the optical fiber cable under test. The optical return loss test is performed using an optical return loss meter.
