Corning Inc. of Corning, N.Y., has announced that it will use the restricted mode launch bandwidth measurement specification on its InfiniCor 300 and InfiniCor CL 1000 multimode fiber for 850-nm laser operation. The standard is the result of work by a task force from the Telecommunications Industry Association of Arlington, Va., and is intended to replace the minimum overfilled launch bandwidth standard, which was developed for use with LEDs on multimode fiber.

Restricted mode launch has not been validated for specifying 50-µm multimode fiber or fiber that employs 1300-nm laser sources. Corning will continue to use its own measurement specifications for these components.
