Proximion Intros Industry's First Patch Cord Dispersion Compensation Module

 

Proximion Fiber Systems AB, a provider of Fiber Bragg Grating (FBG) based dispersion compensation modules (DCMs), has reportedly launched its Patch Cord Dispersion Compensation Module (DCM (News - Alert)-PC), the newest member of its dispersion compensation product line.

 

Claimed to be the industry’s first patch cord solution, the DCM-PC is a low-cost, small footprint solution that is said to combine continuously chirped Fiber Bragg gratings into a simple patch cord. According to the company, integrating the DCM into the cable eliminates the need for a separate piece of hardware for dispersion management.

 

“As service providers upgrade networks to 10 gigabits and beyond, dispersion becomes a newfound problem,” said Stefan Ekman, chief executive officer at Proximion, in a statement. “Operators and system vendors are using patch cords to deliver signals and by utilizing the cable with the DCM add-on, they are eliminating the need for another piece of hardware to maintain while solving the dispersion issue. The DCM-PC is a cost-effective, rugged option in small form-factor.”

 

The company also said that the newly launched DCM-PC provides the same functionality as DCF or traditional DCMs while replacing dedicated and costly terminal floor space needed to house hardware or DCF spools. Moreover, the DCM-PC connects one board to another, consequently replacing the need for two additional patch cords.

 

With this launch, vendors and operators can now conduct dispersion in networks ranging from TDM-based metropolitan and regional networks to channel or sub-band specific residual dispersion compensation in submarine DWDM terminals. The gratings are installed in a 30-to-110 centimeter long patch cord rather than in a separate module. Built on Proximion’s unique and proprietary FBG manufacturing technology, the patch cord DCM is suitable for deployment in SONET/SDH and 10 gigabit Ethernet networks, in cable television or WDM networks.

 

Reportedly, the DCM-PC is available in different choice that tightly controls the dispersion from -1300 to +1300 ps/nm over a 6.5 nm wide band.

 

Proximion also said that the newly launched patch cord DCM will be available for shipping to system houses and service provider from the third quarter of 2009.

 

As TMCnet reported earlier, Proximion unveiled a residual dispersion slope compensator that is designed for submarine and ultra long-haul applications.
