Fiber Optic Attenuator

Fiber Optic Attenuator

The AFS variable attenuators are ideal for simulating cable loss for lab testing of link power margin or reducing power in links where receivers are being overloaded. These variable attenuators works on a gap-loss principle. Pulling the connector end-faces apart induces the loss. Since the light exits in an expanding cone, the receiving fiber will capture less light, as the gap gets larger.
