Erbium-doped fiber amplifiers News
Optical Amplifier Breaks Low-Noise Record
GOTHENBURG, Sweden, June 23, 2011 — An optical amplifier that can amplify light with extremely low noise has been demonstrated at Chalmers University of Technology. The new amplifier enables a reach increase for optical fiber signals from, for example, 1000 to 4000 km. This could lead to better Internet traffic and laser radar technology and could promote applications where detection of very weak levels of light is essential, such as free-space communication. Because of the demand for increased data capacity, optical...
JDSU Delivers 1 Millionth Pump Laser
MILPITAS, Calif., Oct. 12, 2010 — JDSU announced that San Jose, Calif.-based ADVA Optical Networking is the recipient of JDSU's one millionth 980 nm pump laser. Pump lasers are used to power erbium-doped fiber amplifiers, a critical optical component that regenerates weakened...
Vytran to Showcase FAS at OFC/NFOEC
MORGANVILLE, N.J., March 22, 2010 - Vytran LLC will demonstrate a range of fiber processing equipment, including its fully automated FAS fusion splicing workstation, at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference 2010 (OFC/NFOEC)...
Mode-Matching Technique May Enable Broad Telecom Bandwidths
Jul 1, 2008 — Erbium-doped fiber amplifiers (EDFAs) are widely credited with enabling the huge growth of fiber optic communications during the last decade of the 20th century. Because they could boost the amplitude of optical pulses traveling in fiber without...
