We have developed very compact serial 10-Gb/s optical modules for 640-Gb/s WDM interunit interconnection for a Tb/s ATM switching system. The transceiver module contains a very compact laser unit with an EA modulator and a 16:1 MUX which multiplexes sixteen 622-Mb/s parallel signals into one serial 10-Gb/s signal. The receiver module contains a 10-GHz PLL synchronizer, a 1:16 DEMUR which demultiplexes a serial 10-Gb/s signal into sixteen 622-Mb/s signals and a word-synchronizer LSI for ATM-cell regeneration. These optical modules have a novel cooling structure. As a result, we have developed very compact optical transceiver and receiver modules, of equal size: 80×120×20mm.
