5dB Fiber Optic Attenuator LC UPC SX SM 2.0mm Cable Customized
Length Precise Attenuation Values
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 orLC/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
screw
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.

Detailed Picture
Operation of Variable Optical Attenuator
With above excellent characteristics, variable fiber optic in-line
attenuators can be used in fiber optical telecommunication system
and optical transmission system. These attenuators can be applied
in FTTH, CATV, LAN, fiber optical sensor and subscriber loop. They
are often used as the testing equipment.
Application
Variable in-line optical attenuators comprises a dual fiber
collimator and a reflection component separated by a linear
moveable ND filter. They are used to permit dynamic control of
optical power levels in a fiber and can be applied to adjust power
level of signal in the optical communication at the output of light
sources, E/O converters and for the linear or dynamic range of
power meter.
