Single Mode Standard Couplers --SC-1×2, 2×2
Single mode couplers are used to split light with minimal loss from one to tow fibers or to combine light from tow fibers into one fiber. These components are excellent for duplex transmission on a single fiber, CATV systems or within fiber optic test sets.

Features

Low loss
Low polarization dependence
Environmentally stable

Applications

Optic communication system
LAN
CATV
Fiber optic sensor
Test instrument
