Multi Mode Fused Fiber Couplers

Product Description: 

Fused couplers are ideal components to split or combine light signals between two fibers over a wide wavelength and temperature range. They are constructed by fusing and tapering two fibers together. The fused fiber couplers have low excess loss, low back reflection, high stability, high reliability and compact size. Both 1X2 and 2X2 types are available.

Specification: 

Central Wavelength (nm)
850, 1310, 1550 or other wavelength
