EMCORE reveals 6.5 GHz bandwidth lasers for DAS applications

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 -40°C to +85°C. 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. ...
