Single Window Single Mode Wideband Tree/Star Coupler (nxm)
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.
