CD compensation market to net $30 million by 2005

Dec. 1, 2003
The worldwide consumption value of filter-based devices providing variable chromatic dispersion (CD) compensation for high-speed telecommunications networks (at 10 Gbits/sec or faster) will increase from just $580,000 in 1999 to an estimated $30 million in 2005, details a new report from ElectroniCast (San Mateo, CA).

System operators are upgrading their links toward 10- and eventually 40-Gbit/sec transmission speeds and using DWDM to increase network capacity. CD can be problematic at higher transmission speeds, since carriers are dealing with legacy optical fiber of varying quality. Increases in transmission speed, optical-fiber link length, DWDM, and optical add/drop multiplexers (OADMs) will drive the demand for dispersion compensators. Dispersion-compensating filter-based modules (DCMs) are passive grating- or etalon-based packaged devices that are deployed in various locations within optical-network links.

"Filter-based variable (tunable) CD-compensating modules are used as a complimentary premium as well as an alternative to installing a specific length of dispersion-compensating optical fiber, other fiber-based solutions, or electronic chip-based options in the telecommunications link," explains ElectroniCast president Stephen Montgomery. "These devices are used in conjunction with an OADM, optical-amplifier nodes, signal reconfiguration, test/measurement, and other application functions."
