100Gbit/s compact transmitter module integrated with optical multiplexer

The 100 Gbit/s compact transmitter module for CFP4 is presented for the first time, where the optical multiplexer, quad-channel LD driver, and four laser diodes are all integrated in the small package. The very clear eye openings at 25 Gbit/s are confirmed with very low power consumption up to 1.2 W in the case temperature range from -10 to 75 degC.
