Compact Optical Transmitter Module with Integrated Optical Multiplexer for 100 Gbit/s

摘要

High-speed and small-sized transceivers are strongly required to support the rapidly growing internet traffic. The CFP (100G form-factor pluggable) using four-wavelength LAN-WDM (wavelength division multiplexing) is now widely used. To increase the transmission capacity of a line card, CFP4, a very small transceiver, has been standardized. To support this trend, we have developed a 100Gbit/s compact optical transmitter module for CFP4 and integrated a compact low-loss optical multiplexer, a quad-channel laser diode driver, and four laser diodes. The module achieves clear eye openings at low power consumption. This paper describes the design and basic characteristics of the module.
