Proximion Intros Single Channel Dispersion Compensation Module

By Anshu Shrivastava, TMCnet Contributor

Proximion Fiber Systems has released its new single channel dispersion compensation module (DCM (News - Alert)-SC), which is expected to extend single channel SDH/SONET/GE system reach, otherwise limited by the dispersion tolerance of the transceivers.
DCM-SC delivers improved flexibility and performance in a small form factor and the wide optical bandwidth and the low group delay ripple ensure “high transmission quality.”
Proximion also offers the option of different customized wavelengths, suitable for other applications and network solutions.
“The DCM-SC is perfect for those customers that need a cost effective product with a small form factor as well as wavelength flexibility,” said Stefan Ekman, CEO at Proximion.
He also said that the importance of importance of dispersion management is increasing in all parts of the networks.
He added: “We are already an established supplier to a number of systems vendors for applications up to 40Gbps and have a complete product portfolio of dispersion management solutions.”
DCM-SC is currently available on volume basis.
Proximion is a provider of optical modules and sub-systems based on fiber bragg grating (FBG) technology. The technology produces dispersion compensation modules with the advantages of having no non-linear effects, no latency.
In addition, it has a low power loss compared to the alternative of traditional dispersion compensating fibers (DCFs). Typical DCF has negative dispersion and produces a negative slope, with nominal values that are typically ten times higher than those of the
fiber to compensate for.
Back in March, Proximion and RED-C (News - Alert) Optical Networks announced their cooperation in promoting an erbium doped fiber amplifier (EDFA) design optimized to take advantage of the properties of DCM technology.
In optical fiber communications, dispersion compensation modules can be used for compensating the chromatic dispersion of a long span of transmission fiber.
