The new TR-FC13R-N00 is a 100Gb/s transceiver module designed for optical communication applications compliant with 100GBASE-LR4 of the IEEE 802.3ba
The difference between the MLG and a standard gearbox based on IEEE 802.3ba
is that rather than requiring all 10 lanes to be bonded as 10x10G with zero ppm offset, MLG allows independent 10GE or 40GE lanes, separated by up to +/- 100ppm to be multiplexed into a single 100GE pipe.
The LineSpeed MSH110 IC is a single chip, CMOS device designed to support IEEE 802.3ba
and OIF CEI-3.0 electrical standards.
Depending on required distances, the speed foresees IEEE 802.3ba
different transmission methods.
The two most established 100-GbE optical transmission specifications, both covered in IEEE 802.3ba
, are long-reach 100GBASE-LR4 and extended-reach 100GBASE-ER4.
The new IEEE standard 802.3ba
was ratified in 2010 and addresses requirements for 40/100G using parallel optics.
The IEEE 802.3ba
standard has a cabling skew of 79 ns.
NeoPhotonics added that its 40G transceiver is designed primarily to connect gigabit and terabit routers and switches with next generation high capacity transport systems and complies with the IEEE 802.3ba
40GBASE-LR4 specification and to support OTU3 rates and 44.4G for future applications.
During the development of the 802.3ba
standard, which defines both 40-Gigabit and 100-Gigabit Ethernet, several months were lost to a debate over which speed the group should be aiming for, he said.
The Opt-X Unity system was designed specifically to meet IEEE 802.3ba
requirements and new 100GBASE-SR10 and 40GBASE-SR4 equipment.
