Oplink’s single window, single mode wideband tree and star couplers are high port

count bi-directional products with excellent performance over a wide bandwidth. They

have very good uniformity, low excess loss and very low polarization sensitivity. All

devices are tested according to industry standard test procedures and are supplied

with all pertinent measurement data.

Oplink can provide customized designs to meet specialized feature applications. Also,

Oplink offers modular assemblies that integrate other components to form a full

functionmodule or subsystem.
