The 10-GE transponder module is double the size of the 2.5-Gbps transponder modules and requires a special 10-Gbps line card motherboard. You can install up to two 10-GE transponder modules in a 10-Gbps line card motherboard. Each transponder supports one client side and one trunk side interface. The client side is a short-reach 1310 nm interface and the trunk side interface is an ITU Grid compliant 15xx nm long-reach interface. The transmitter supports a 1260 nm to 1355 nm wavelength range. The 10-GE transponder module is available in 32 versions, one for each of the 32 ITU channels it supports.The 10-GE transponder module is not protocol independent, it supports the 802.ae specification for 10GBASE-LR interfaces.
