StockerYale announces Erbium-Doped Fiber

Mar. 16, 2001--StockerYale, Inc., an independent provider of phase masks, specialty optical fiber and specialized illumination products, announced its new line of Erbium-Doped Fiber.

StockerYale, Inc., (NASDAQ:STKR), an independent provider of phase masks, specialty optical fiber and specialized illumination products, announced its new line of Erbium-Doped Fiber. Erbium-Doped Fiber is a critical sub-component used in the development and manufacture of Erbium-Doped Fiber Amplifiers, (EDFAs).

Due to the intrinsic properties of erbium, Erbium-Doped Fiber assists in the regeneration of an optical signal when it passes through the EDFA, a device that amplifies light signals through optical networks. When configured within long-haul terrestrial or submarine telecommunications systems, EDFAs enable an optical signal to be sent greater distances with increased reliability. They are typically designed with pump laser modules, in-line optical isolators, wavelength division multiplexers, and Erbium-Doped Fiber.

StockerYale's Erbium-Doped Fiber is targeted at the wavelengths supported by the most widely used EDFAs and will include fiber that is optimized for use within the C and L band.
