Wavelength Division Multiplexing (WDM) and BIDI

10G, 25G Tunable DWDM

Multi-Code, Dual Rate and Dual Mode Option Available!
400G & 800G Ready!



Form T1Nexus CWDM (Coarse Wavelength Division Multiplexing) modules and chassis support up to 18 wavelength channels through a single fiber. The flexible technology allows it to be deployed on common fiber networks where distance is limited, such as telecom access networks or school campuses.



T1Nexus DWDM (Dense Wavelength Division Multiplexing) modules and chassis, support up to 40 (C21-C61) wavelength channels through a single fiber allowing the transmission of large amounts of data by packing more wavelength channels into a single fiber. DWDM technology provides long transmission distances at high-speed data rates.


Bi-Directional (BiDi)

T1Nexus Bi-Directional modules allow you to double the density of your existing single-mode fiber in speeds from 1G to 10G at distances up to 120km with T1Nexus CWDM/DWDM and Bi-Directional Optics.
