Fiber Optic Attenuator 0~50DB FC ST LC SC Single Mode Variable
Single Mode Variable Optical Attenuators allow the user to manually vary the attenuation of the signal in
the fiber as it is transmitted through the device.
These VOAs can be used to to precisely balance the signal strengths
in fiber circuits or to balance an optical signal when evaluating
the dynamic range of the measurement system. The maximum specified
attenuation is achieved within 10 turns of the adjustment screw.
All in-line VOAs have single mode fiber pigtails with a Ø3 mm
jacket. The VOAs are offered unterminated or terminated with 2.0 mm
narrow key LC/SC/ST/FC/PC or LC/SC/ FC/APC connectors.
Each attenuator has a lens to collimate the light from the input
fiber. A blocking device or window can be manually adjusted by a
Then, a second lens is used to couple light into the output fiber.
Thus, the coupling efficiency is changed until the desired
attenuation is obtained.
