Single
Mode Standard Couplers --SC-1¡Á2, 2¡Á2
|
|
¡¡¡¡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.
