Module replaces DCF in DWDM networks

Optoelectronic products developer Civcom is launching a free-path Manageable Dispersion Compensation Module (M-DCM) this month. The M-DCM device is a manageable Dispersion Compensation Fiber (DCF) replacement designed for Metro-Regional DWDM networks.

The company has incorporated an etalon based in-house TODC technology in a small package, allowing a significant step forward in the design and operation of the module, according to the press release. The M-DCM is used to compensate for chromatic dispersion value ranging from -1,700ps/nm to 1,700ps/nm using in-house intellectual properties.

The M-DCM enhances the network by lowering insertion loss and power consumption and providing manageability, the company said. The module reduces in-line amplification requirements and allows remote managing of dispersion while using a single part number as a substitute to multiple DCF part numbers. With its high reliability, stable performance and wide dynamic range, this multichannel module is suitable for metropolitan networks across the entire C-band, said Civcom.

"Using the M-DCM as an alternative to DCF will improve performance and flexibility and create real differentiation in the network's design; ultimately leading to lower operating costs for the end-user," said Civcom CEO Meron Raz. "In a field that has a growing requirement for agile networks, we believe this introduction is a vital extension to the existing DWDM product line, and will help us serve our customers more effectively."
