Specialty optical fiber manufacturer Fibercore Limited has announced the launch of two erbium doped fibers, METROGAIN and ISOGAIN, designed to address the specific requirements of high channel count DWDM and metro networks.

ISOGAIN will provide component manufacturers and systems developers with gain flatness that exceeds the state of the art in high channel count DWDM applications, contends the company, while METROGAIN offers Erbium-doped fiber amplifier (EDFA) manufacturers a reduced cost and higher performance fiber in both 125-micron and reduced form factor 80-micron diameters.

Both fibers provide reliability and geometric precision over and above Telcordia requirements, claim company representatives, with the 80-micron METROGAIN product offering significant handling and reduced susceptibility to static fatigue over traditional fibers, even in the latest generation of small form factor components.

"ISOGAIN's market-leading spectral characteristics are a testament to our concentration on developing specialty fiber for a variety of industries," asserts Dr. Chris Emslie, managing director at Fibercore Limitited. "Developing these properties in a reduced diameter fiber, in the case of METROGAIN, will be a significant breakthrough for the market as it re-emerges from the recent depression. Our ability to provide fibers with lifetimes and reliability in line with telecommunications requirements for use in reduced form factor packages will give the market a much needed boost," he adds.

Fibercore Limited is headquartered in London and Southampton, UK.
