LONG BEACH, Calif. - May 19, 2002 - Nufern, an independent provider of application-specific optical fiber, has released its erbium-doped C-band fiber, EDFC-980-HP (high-performance). Designed for use in single or multi-stage amplifiers and ASE sources, Nufern's EDFC-980-HP can be powered with 980 nm or 1480 nm pumps.
Through a unique solution-doping technology we are able to deliver erbium fibers with highly consistent and reproducible spectroscopy, said Nufern's CTO, Dr. Adrian Carter. Nufern's extensive characterization labs and statistical process control plant provide fiber with the kind of detailed characterization data and tight optical and mechanical tolerances needed by amplifier manufacturers. And as an independent manufacturer, customers can be assured of a secure supply of a premier fiber from a stable, non-competing source.
Nufern's EDFC-980-HP has a peak absorption near 1530 nm of 6.0 1.0 dB/meter, a cut-off wavelength of 920 ± 50 nm, and a typical numerical aperture of 0.23. This fiber has a core-clad concentricity error of < 0.3 µm to ensure low splice loss and comes with a standard 200 kpsi proof strength for high reliability. Each lot of Nufern's erbium-doped fiber is furnished with extensive lot specific characterization data.
Nufern is the largest independent manufacturer of highly engineered, application-specific optical fiber (ASOF) for components and systems serving the telecommunications, industrial, medical, and aerospace industries. With manufacturing facilities located at its headquarters in East Granby, Connecticut, USA, Nufern is able to engineer, make, support, and deliver large volumes of commercial-grade ASOF to customers around the world. Nufern products include polarization maintaining fiber, planar waveguide fiber, metalized fibertails, select cut-off single-mode fiber, photosensitive fiber, ultra-high numerical aperture fiber, and specialty-coated fibers.
