Coarse WDM Transceivers (OPN Trends Supplement)

Brian E. Lemoff

As high-end DWDM technology becomes pervasive in long-haul networks, WDM technologies smaller in cost and size are emerging for short-distance local area network and access applications. For example, tiny coarse-WDM transceiver modules will soon integrate a multiwavelength array of lasers and an optical multiplexer and demultiplexer.
