Loopbacks
Amphenol Fiber Systems International
Amphenol Fiber Systems International (AFSI) has developed the Loopback TFOCA and TFOCA-II® plug configuration as an aid to system maintenance and troubleshooting of the tactical cable reels and systems that use them. The Loopback plugs come in a variety of configurations from 0 dB to -23dB to simulate a system operational condition. The use of the Loopback plug enables a technician to test a cable reel in the bi-directional mode by simply swapping leads on the test meter, thus saving considerable time and effort in establishing a systems operational status.
