Dual Windows, Single Mode

Windband Tree/star Coupler (nxm)

DWTC Series

Oplink’s Dual window, single mode wideband tree and star couplers

are high port count bi-directional products with excellent perfor-

mance over two wide wavelength bands.They have very good unifor-

mity, 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.
