Adjustable Type Fiber Opt - Telecommunications Products

Adjustableoptical attenuator Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal. It is often used to limit the optical power received by the photo detector to within the limits of the optical receiver. Features: High Precise attenuation value Perfect environmental stability and reliability Low additional loss Flawless end face Wide attenuation range (variable) Application:Fiber optical telecommunication system FTTH, CATV, LAN Subscriber loop Fiber optical sensor Testing equipment Specification: Item Unit Parameter Operating Wavelength nm SM:1310/1550nm MM: 850 /1300nm AttenuationRange dB 1-10dB(1dB step), 15, 20, 25, 30dB Return Loss dB PC:?50 UPC: ?55 APC: ?60 Attenuation Tolerance dB ?+/-0.5(1-10dB) or ?+/-1.0(11-30dB) Working Temperature ? -25?~+75? Storage Temperature ? -40?~+ 85?
