Fixed buildout attenuator 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.

Arkoptics FC UPC attenuator is capable of performing at 1310&1550, C and L Bands,can meet with 1260nm to 1620nm full range bandwidth application.These FC 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. These FC fixed attenuators are plug in type, it allows to be used directly on the end of a patchcord, which in turn can insert directly into an adaptor. Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution makes them ideal for DWDM,EDFA,DWDM OADM and CATV network link

We will stock both FC APC and FC UPC singlemode attenuator range from 1dB to 30dB.Shipment via FedEx,DHL, or UPS so as to catch up the fastest lead time for the network operators worldwide.
