Title:
40,50 AND 100 GB/S OPTICAL TRANSCEIVERS/TRANSPONDERS IN 300PIN AND CFP MSA MODULES
Document Type and Number:
WIPO Patent Application WO/2010/134986
Kind Code:
A3
Abstract:
Disclosed by way of exemplary embodiments, a 40/50/100Gb/s Optical Transceivers/transponders which use opto-electronic components at data rates collectively that are lower than or equal to half the data rate, using two optical duobinary carriers. More specifically, the exemplary embodiments of the disclosed optical transceivers/transponders relate to a 43Gb/s 300pin MSA and a 43~56Gb/s CFP MSA module, both include a two-carrier optical transceiver and the appropriate hardware architecture and MSA standard interfaces. The two-carrier optical transceiver is composed of a pair of 10Gb/s optical transmitters, each using band-limited duobinary modulation at 20~28Gb/s. The wavelength channel spacing can be as little as 19~25GHz. The same principle is applied to a 100Gb/s CFP module, which is composed of four tunable 10Gb/s optical transmitters, with the channel spacing between optical carriers up to a few nanometers.
