Overview

Microwave Distributed Feedback (DFB) Laser provides exceptional performance for linear fiber optics communications in very wide bandwidth applications. ML1001 linear fiber optic lasers are an excellent alternative to using coaxial cable systems to transmit 10 MHz to 18 GHz signals. They offer significant improvements in reliability of microwave communications networks by transmitting the RF signal in its original format. Liniobate offers DFB lasers with a 3dB frequency response bandwidth above 20 GHz for applications that rely on high-speed direct modulation.These lasers are offered in standard 7-pin butterfly package with RF (K) connector, internal thermoelectric cooler, isolator, and polarizationmaintaining (PM) fiber pigtail with FC/APC connectors.Other configurations ( no-isolator, single mode fiber, etc) are available upon request.
