Corning to Achieve New Laser Bandwidth Measurements

CORNING, N.Y., Aug. 16 -- Corning Inc. has announced that it will specify laser bandwidth on its InfiniCor 300 and InfiniCor CL 1000 multimode fibers using the Restricted Mode Launch (RML) bandwidth measurement specification. RML bandwidth measures the performance of laser-based systems used in high-speed networks. Products at the 850-nm wavelength will have minimum RML bandwidth values.
Multimode fiber was previously specified according to a minimum Over-Filled Launch (OFL) bandwidth standard. The OFL standard was an acceptable way of specifying bandwidth in multimode fiber when used with LEDs at lower speeds, but may not meet expected requirements in high-speed networks using laser light sources, said Corning.
