Product Details
ST Fixed Optical Fiber Attenuator Male to Female Singlemode with
attenuation 1~25dB
Optical attenuator is a passive device used to reduce the power
level of an optical signal. It is generally used in single-mode
long-haul applications to prevent optical overload at the receiver.
Optical attenuator is widely used in CWDM&DWDM, CATV systems,
data center networks, test equipment
Features:
Low back reflection and Low PDL
High precision attenuation value
Precision control of attenuation range
Wide attenuation range
Precision ceramic ferrule
FC, SC, ST, LC … optional
Plastic or metal housing material
Application:
Fiber Optical distributing frame
Fiber Optical network system
High speed fiber optical transmission system
CATV system
Long distance DWDM system
Optical add-drop multiplexers(OADM)
