Ultra Hi-Rel Undersea Component Family
Single Window Single Mode Wideband Fiber
Coupler(1x2,2x2)
UWFC Series
Product Description
Oplink’s single window wideband couplers split or combine light with excep-
tional performance over a wide bandwidth. These couplers have very good
uniformity, low excess loss and very low polarization sensitivity. All devices
are supplied with all pertinent measurement data. Please contact our Oplink
OEM design team for further information.
Oplink’s Ultra Hi-Rel family of optical components are available for your un-
dersea applications. Please contact us with your requirements.
