Coupling and splitting are basic elements within fiber-optic networks in terms of power tapping and combining or band splitting and multiplexing. Coupling/splitting devices and modules can act as small components within various optical modules/subsystems for long-haul and metro signal transmission, amplification and monitoring/conditioning systems as well as major building blocks for local area passive optical access networks.

Oplink provides a wide range of optical coupling/splitting components based on Thin-film Filter (TFF), planar waveguide, and Fused Biconical Tapered (FBT) technologies. Oplink's product advantages include excellent performance specifications, one stop-complete design capabilities in OEM and ODM and low-cost vertical integration solutions for optical modules, systems and subsystems.
