DUPLEXING WDM 1310/1550 NM AND 1625 NM
Fused Fiber WDM
The Duplexing WDM enables the low loss combining or splitting of a pair of wavelengths.
1310 nm/C band or 1310 nm/L band components are used to double network bandwidth whilst the 1310/1625 nm component is used to add or drop a supervisory wavelength from a system.
Gooch & Housego proprietary manufacturing technology provides uniquely low excess loss and wavelength dependence along with low polarization and temperature dependence for all ports.
In addition to the standard wavelengths shown, other combinations such as 1550/1625 nm are available. Please contact us with your specific requirements.
