EMCORE Corporation has announced the introduction of its new Coaxial Distributed Feedback (DFB) Laser Module, Model 1999, for next-generation wireless fiber optic link applications. The 1999 laser module features wide bandwidth above 6 GHz and is designed for 5G, Distributed Antenna Systems (DAS), L-Band and wireless remoting link applications.

The 5G wireless migration is underway with all three of South Korea’s mobile network operators now offering the world’s first ultra-fast 5G services in multiple cities. Full-blown 5G smartphones are available and early results show a significant uptick in data use among 5G customers according to SK Telecom. EMCORE’s new 1999 laser module is an ultra-linear, coaxial DFB laser module operating at wavelengths from 1270 to 1550 nm that is optimized for 5G wireless fiber-optic links. It’s designed to enhance bandwidth and signal integrity to meet the increased data demands of 5G networks for the delivery of consistent, reliable wireless signals.

Featuring optical output power up to 10 dBm, the 1999 laser delivers superior optical performance over an enhanced temperature range from -40 °C to +75 °C with very low power consumption. The 1999 can be cooled with external Thermo-Electric Coolers (TEC) for high-stability or run without TEC’s to further reduce power consumption. The unit is packaged in a compact, hermetic assembly together with a monitor photodiode and isolator for flexible integration into various transmitter configurations.

The new 1999 laser follows the successful release of the Model 1998 at last year’s MWC in Los Angeles and builds on EMCORE’s track record of high-performance designs for wireless and high-speed digital applications. With bandwidth above 6 GHz, the 1999 will deliver maximum high-speed signal integrity, raising the performance bar in linear fiber optic transmission in 5G, DAS and long-distance fiber-optic link networks.

EMCORE is showcasing the new Model 1999 and Model 1998 lasers, along with their complete line of lasers, optical receivers, and photodiodes at the Mobile World Congress Los Angeles from October 22 to 24, Booth #S-2461.
