FC/APC fiber terminator UPC APC optical fibre terminator ftth connector

Optical fiber terminator is a passive device which absorbs optical power to eliminate interference caused by optical signal reflection to link. This device is used in dense wavelength division multiplexing (DWDM) and erbium doped fiber amplifier (EDFA) optical fiber transmission link open port, can be effective in the transmission distance of 2CM absorbed optical power, optical fiber finalizers can effectively eliminate the optical signal reflection is not necessary, in order to ensure the stability of high power transmission link.
