Optical fiber attenuator male to female type is a passive device used to reduce the signal power of a fiber network link.This metal-ion doped fiber attenuator allows for higher performance than fiber splice or fiber offsets, which function by misdirecting rather than absorbing the light signal.

SC APC attenuator features a fiber endface that is polished at an 8-degree angle.The angled endface of APC attenuator causes reflected light to reflect at an angle into the cladding versus straight back toward the source,thus APC attenuator’s return loss should be -60dB or greater. 

Arkoptics SC APC fiber optic attenuator is capable of performing at 1310&1550, C and L Bands,can meet with 1260nm to 1620nm full range bandwidth application.These SC APC optical attenuators can withstand over 1W of high power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications.Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution makes them ideal for DWDM,EDFA,DWDM OADM and CATV network link.
Dope fiber type SC APC male-female attenuator is plug in design.It allows to be used directly on the end of a patchcord, which in turn can insert directly into an adaptor. We will stock SC APC and SC UPC singlemode attenuators from 1dB to 30dB so as to catch up the fastest lead time for the network operators worldwide.
