The TM-Series is a family of CWDM and DWDM carrier-class optical transport products that provide the transport of any service between 100Mb/s and 10Gb/s in multi-reach transport applications. Enabling cost efficient increase of metro network capacity, it uses CWDM/DWDM technology in an innovative way for the best transport network economics.

With multi dimensional scalability, the TM-Series’ products allow the CWDM/DWDM network to grow, both in size and functionality. Furthermore, Integrated Ethernet capabilities provide the possibility for cost efficient service differentiation and revenue base expansion.

The TM-Series supports carrier-class infrastructure applications such as mobile transmission networks, triple-play/CATV backhaul networks, carrier services, SDH/SONET transport and capacity expansion, Gigabit Ethernet transport for Next Generation Networks and wavelength service delivery. The unparalleled modularity and scalability of the TM-Series enables cost efficient low entry deployments with the reassurance of economic capacity growth to match growing demand.
