1997 Uncooled, Coaxial DFB Laser Diode

EMCORE’s Model 1997 uncooled, coaxial DFB laser offers a low-cost solution for next-generation, wireless linear fiber optic links. The 1997 laser module features extended bandwidth to 6 GHz and is optimized for 5G, DAS (Distributed Antenna Systems) and small cells applications. It is designed to enhance bandwidth and signal integrity for delivery of consistent, reliable wireless signals in temperature-controlled indoor environments.

These components can be cooled with external thermo-electric coolers for high-stability or run without TEC’s to reduce power consumption. The DFB laser builds upon EMCORE’s long history of high-performance, leading-edge designs in wireless and high-speed digital applications. The laser diode devices are packaged in a compact hermetic assembly together with monitor photodiode and isolator, for flexible integration into various transmitter configurations.
