Dual Windows, Single Mode
Windband Tree/star Coupler (nxm)
DWTC Series
Product Description
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.
