 The TM-xSFP 
transponder is part of the Fiber Driver-LD (LambdaDriver?) product line and can 
be hosted by the LD400, LD800 and LD1600 chassis.
 The transponders are single 
slot modules that interface between the CWDM or DWDM multiplexers and the 
terminal equipment. These modules provide
 transparent light paths at ITU-T 
grid CWDM/DWDM wavelength, which can carry any data centric protocols at any 
rate from 2 Mbps to 2.7 Gbps, enabling carriers to
 mix different protocols 
such as SONET/SDH, Fast Ethernet, Gigabit Ethernet, Fibre Channel, ESCON, etc. 
in a same chassis.
