Product Description

Attenuators are key in controlling the power level of an optical path in fibre optic telecommunication systems. OFS' SC and LC Build-on Fibre Optic Attenuators are used to reduce excess optical power from the transmitter that can result in over-saturation of the receiver. These attenuators can be placed either on the LGX® shelf or directly on the active equipment, depending on the customer's preference and the design of the equipment. Build-on attenuators, available in SC and LC styles, are a combination of a connector on one end, and an adapter on the other. This flexibility allows the attenuator to be plugged into a standard SC or LC adapter. The assembly contains a ferrule that is available in standard polish connectors (PC) and angle PC (APC).
