Fibercore pioneered the first commercial erbium-doped fibers for amplifiers in 1988 and, since then, have developed and improved the technology to provide the high conversion efficiencies demanded by the industry today. Our MetroGain range of fibers, designed for low-cost 'Metro' Type EDFAs offers a broad spectrum ideal for ASE sources, whilst our IsoGain fiber range has a core composition optimized especially for EDFAs deployed in high channel-count DWDM systems, both supported by our GainMaster simulation software.

The development in 1999 of the CP1500Y fiber for our parent company at the time, Scientific Atlanta, heralded a major breakthrough in high-power laser and amplifier technology. Already deployed in thousands of CATV and FTTx systems around the world by SA, and subsequently, Cisco, this revolutionary all-glass, Er/Yb dual-clad fiber was field-proven well before its launch to the marketplace in 2010. It is now complemented by a full range of components.
