Originally developed for the Metro Telecom market, CWDM (Coarse Wavelength Division Multiplexing) technology has become ubiquitous in all telecom markets as well as the subsea market.
The U.S. Navy is examining lasers for detection, identification and destruction of targets in light of more stealthy and speedy threats, according to Aaron Budgor, former Navy program manager for the SDI Firepond laser radar program, who is doing long-range planning for the Naval Research Laboratory.
