Socionext transceiver claims record for 100Gbit/s transmission on a single wavelength
Socionext, the Panasonic-Fujitsu SoC jv, has launched a 100G per wavelength, fully-integrated transceiver based on Discrete-Multitone (DMT) modulation with a power dissipation of less than 5W which, says the company, is a record for transmission of 100Gbit/s using a single wavelength.

Socionext, the Panasonic-Fujitsu SoC jv, has launched a 100G per wavelength, fully-integrated transceiver based on Discrete-Multitone (DMT) modulation with a power dissipation of less than 5W which, says the company, is a record for transmission of 100Gbit/s using a single wavelength.
Migration to 100G optical links between data centres has started. The need for low-cost, efficient transport at the physical layer is key to supporting growth in both these markets, in addition to the requirement to maximize fibre capacity by driving 100Gbit/s over a single wavelength.
One way to do this is to use multi-level signalling to increase the symbol rate and run a higher bit rate for the same Baud rate. Using this technique (2 bits/symbol) to get from 25Gbit/s per wavelength, a standard binary signalling rate, to 50Gbit/s is a good step forward. But to get to 100Gbit/s, the next step is to double the Baud-rate to 56GBaud.
