Profile: Multiplex, Inc. is a manufacturer of high-end active photonic components and subsystems for optical networks. We provide high-speed electro-absorption modulated lasers, high-sensitivity photo receivers, tunable transceivers and transponders. We are an ISO 9001:2000 certified company. Our products include lasers, receivers, 980 pump and transponders. Our MTTX510 tunable electro-absorption modulated laser module consists of a tunable multi-quantum-well laser and a monolithically integrated electro-absorption modulator. It is available in a number of industry-standard hermetic packages. The electronic wavelength tuning time is less than 10 ns. Temperature wavelength fine-tuning can also be used in applications where fast tuning is not required.
