Fiber Optic Attenuator (Fixed type)

| DESCRIPTION

Attenuators are used to reduce excess optical power from the transmitter that can results in over-
saturation of the receiver. These attenuators are available in SC, LC, ST, FC and MU style with APC, UPC.
The front of the attenuator is a male plug connector style that allows the attenuators to be plugged
directly into receiver equipment or adaptors in patch panel. KOC’s optical attenuators have been
recognized as “Korean World-class Products” by the Ministry of Knowledge Economy.
