EMCORE reveals 6.5 GHz bandwidth lasers for DAS applications

Date: 10/04/2017
EMCORE Corporation has introduced 6.5 GHz ultra-linear distributed feedback (DFB) laser modules, the 1618A and 1718A. These new wide bandwidth laser modules are designed and optimized for the next-generation Wireless and Distributed Antenna System (DAS) applications.

Greater demand is created for deployment of wireless systems due to the increasing demands on wireless networks from social media, text, email, uploading and downloading of apps, music, videos and photos. Network providers are building DAS systems in subway tunnels, massive stadiums, high-speed trains and other public environments.

The new 1618A, 1310 nm and 1718A, 1550 nm DFB ultra-linear lasers are designed specifically to target these systems. The bandwidth and signal integrity are enhanced to enable the delivery of consistent, reliable wireless signals where interference is high, or signals are normally weak. The 1618A and 1718A laser modules are packaged in EMCORE's classic 14-pin butterfly cooled laser form-factor which delivers linear optical performance over temperature range of -40C to +85C. These lasers are matched to 50 Ohm systems typical of wireless networks.

"EMCORE's laser technology is world renowned and with these new models we continue to raise the performance bar in linear laser modules for the advanced communications networks," said Dr. Henry Cheung, EMCORE's Senior Product Director. "With bandwidth up to 6.5 GHz, the 1618A and 1718A deliver maximum high-speed signal integrity for Wireless and DAS networks, and long distance fiber optic links," added Dr. Cheung.

EMCORE has also re-launched its 1742, 1550 nm microwave DFB laser module with upgraded bandwidth from 13 GHz to 18 GHz. EMCORE says that this module is suitable for applications including military communications, antenna remoting, telemetry, timing, reference signal distribution, measurement and delay lines. The laser can be integrated into a complete transmitter either as a flange-mount for extreme environments, or as a plug-in for EMCORE's rack-mount systems.
