Gigabit Ethernet TDM Module

Gigabit Ethernet TDM ModuleGigabit Ethernet TDM Module Chassis

With the Gigabit Ethernet TDM module it is possible to double the capacity of Gigabit Ethernet. With the time division multiplexing (TDM) technology two Gigabit Ethernet data streams (2x 1.25 Gbps 1000Base-X) are combined to one channel (1x 2.5 Gbps). This aggregation is completely transparent for each Gigabit Ethernet channel. Switch features such as VLANs, stacked VLANs, Flow Control, buffer management etc. are not affected. The Gigabit Ethernet TDM is equipped with SFP slots for modularity of the optical interfaces. For xWDM applications the line interface can be equipped with a coloured SFP transceiver. For the installation into a 3 U or 4 U Modular Access Platform chassis, the adapter plate must be used. Each adapter plate occupies 6 slots and can hold 2 TDM Modules.
