  SC LC ST FC Fiber Optic Attenuator

 

1. Description

Optical attenuators are commonly used in fiber optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. Sharp bends stress optic fibers and can cause losses. If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired level of attenuation is achieved.

 

2. Application

EDFA, DWDM, Long-haul

Wide-Area networks

Telecommunication networks

Gigabit applications (ATM, Ethernet)

 

3. Characteristics

Fully compatible with SC fiber optic connectors
Precise attenuation values
Industry standard attenuation levels
Low PDL and insertion loss
Precision polishing for reduced back reflection
Highly Reliable Physical Contact Connectors
Compartmentalized case provides safe component storage and simple organization
