MAY 14, 2009 -- ElectroniCast Consultants (search Lightwave for ElectroniCast) has released a new market forecast and analysis of the global market consumption and technology trends of chromatic dispersion compensating filter modules (CDCFMs).
"There are three common device techniques to deal with chromatic dispersion in optical networks -- the use of dispersion-compensating fiber (DCF); the use of chromatic dispersion-compensating filter modules that are typically fiber Bragg grating (FBG) or etalon-based or other filter devices; and electronic and/or photonic chips (PICs)," said Stephen Montgomery, president of Asia-Pacific (APAC) at ElectroniCast Consultants. "With the use of DWDM, especially in high-capacity systems operating at speeds of 10 Gbps and beyond, chromatic dispersion effects can become a real problem," he added.
According to the study results, telecommunication advanced variable/tunable CDCFMs dealing with networks of 10 Gbps or higher held a 58 percent relative worldwide market share in 2008. By 2013, as the need to remotely adjust higher data rates (equal to or greater than 10 Gbps) increases, variable (tunable) CDCFMs (also referred to as CDCMs) serving the 10 Gbps and faster links are forecasted to dramatically increase to a 74 percent relative market share.
Standard variable (tunable) modules for network transmission rates of less than 10 Gbps are forecasted to hold a 14 percent market share in 2013. Fixed CDCFMs will demonstrate slow annual growth in consumption value during the forecast period compared to the variable/tunable filter modules.
Telecommunication CDCFM market forecast data in the new ElectroniCast report are presented for the following product areas:
- standard fixed CDCFM (<10 Gbps)
- standard variable (tunable) CDCFM (<10 Gbps)
- advanced fixed CDCFM (equal to or greater than 10 Gbps)
- advanced variable (tunable) CDCFM (equal to or greater than 10 Gbps)
