Optical Coupler, Optic Couplers

optical coupler

Optical couplers are used in the fiber optical systems to distribution the light powers, it is one of the most important passive components in the system. Usually the optical coupler is MXN types, M is the input end and N is the output end. Most popular optical coupler is 1XN type, like 1X2 optical coupler and 1X3 optical coupler.

Important data regarding the optical couplers include insertion loss, additional loss, splitting ratio and isolation. We supply single mode optical couplers and multimode couplers; typical wavelength is 850nm, 1310nm and 1550nm. We have the single window optical couplers and dual window optical couplers; they can be with different cable length and package, with optional connectors SC/FC/ST/LC, etc.
