Yangtze Optical Fibre and Cable Company, Ltd. (YOFC) today announced further improvements in the attenuation performance of its multimode fiber product line.
The new maximum attenuation specification of 62.5 multimode fiber is reduced to 2.65 dB/km at 850 nm and .60 dB/km at 1300 nm. For 50 micron multimode fiber, the new attenuation specification is 2.25 dB/km at 850 nm and .60 dB/km at 1300 nm.
Established in 1988 by Philips of the Netherlands and China’s Ministry of Post and Telecommunications, YOFC is the largest supplier of optical fiber and cable to the Chinese market and is now exporting product to North America, Europe and the Far East.
Located in China’s "Optical Valley" in Wuhan, YOFC operates the world’s second largest optical fiber manufacturing facility.
"The PCVD process is widely recognized in the industry as the most effective process for making complex index profile optical fibers such as multimode and low water peak single mode fiber," the company says.
"Due to the precise control of the glass deposition in the core of the fiber, the distribution of attenuation values is very tight. The typical attenuation values for 50 micron multimode fiber are <2.20 dB/km at 850 nm and <.50 dB/km at 1300 nm."
