Redfern Optical Components, a leading supplier of next-generation fiber-based components and subsystems for the worldwide optical networking marketplace, is displaying test results of a dispersion compensator
for 512 x 25GHz spaced DWDM channels in a package measuring 2 inches by 7 inches.
In new wavelength division multiplexed (WDM) optical fiber communication systems FBGs are used as wavelength filters and dispersion compensators
(dispersion in optical fiber spreads optical pulses in time and limits the data rate of the fiber link.
It studies the transformation of the Chromatic Dispersion Compensators
(CDCs) market due to commercialization of coherent receivers as well as advanced methods of modulation and employing of Digital Signal Processing (DSP).
Commercial shipments of tunable dispersion compensators
are expected to begin by the end of January and production capacity is expected to increase to pre-flood levels by the end of the March quarter.
They are very useful as wavelength filters and dispersion compensators
in the new wavelength division multiplexed optical fiber communication systems and also make excellent strain sensors that can be networked to obtain distributed strain measurements of large structures, such as bridges and ships.
As a result, Carriers can more than double faceplate density and reduce power consumption by 50 percent, as line card tuneable dispersion compensators
(TCMs) are no longer required.
As such, network operators have been forced to deploy dispersion compensators
throughout their networks to alleviate high PMD levels or else overhaul their entire systems.
