Single Wavelength Singlemode couplers 1310nm, 1480nm, 1550nm
Overview
Specifications
Ordering information
Gould's singlemode couplers are used to split light with minimal loss from one to two fibers or to combine light from two fibers into one fiber. These components are excellent for duplex transmission on a single fiber, CATV systems or within fiber optic test sets
