Emcore launches 6.5GHz-bandwidth laser modules for next-gen wireless and DAS networks

In booth #3407 at the Optical Fiber Comminications trade show (OFC 2017) in Los Angeles (21-23 March), Emcore Corp of Alhambra, CA, USA – which provides indium phosphide (InP)-based optical chips, components, subsystems and systems for the broadband and specialty fiber-optics markets – has launched the 1618A and 1718A 6.5GHz ultra-linear distributed feedback (DFB) wide-bandwidth laser modules, designed and optimized for next-generation wireless and distributed antenna system (DAS) applications.

The increasing demands on wireless networks from social media, text, e-mail, uploading and downloading of apps, music, videos and photos are creating greater demand for deployment of wireless systems, notes Emcore. Network providers are building DAS systems in subway tunnels, massive stadiums, high-speed trains and other public environments. The new 1618A 1310nm and 1718A 1550nm DFB ultra-linear lasers are designed specifically to target these systems, enhancing bandwidth and signal integrity 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 that delivers highly linear optical performance over an enhanced temperature range of -40°C to +85°C. The lasers are matched to 50 Ohm systems typical of wireless networks.

“With bandwidth up to 6.5GHz, the 1618A and 1718A deliver maximum high-speed signal integrity for wireless and DAS networks, and long-distance fiber-optic links,” says senior product director Dr Henry Cheung.

In addition to the new 1618A and 1718A lasers, Emcore has re-launched its 1742 1550nm microwave DFB laser module with bandwidth upgraded from 13GHz to 18GHz. The 1742 provides performance for linear fiber-optic communications in very wide-bandwidth applications including military communications, antenna remoting, telemetry, timing, reference signal distribution, measurement and delay lines. The 1742 laser module 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.
