Single Window, Single Mode
Windband Tree/star Coupler (nxm)
SWTC Series
Product Description
Oplink’s single window, single mode wideband tree and star couplers
are high port count bi-directional products with excellent perfor-
mance 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.
