Emcore Introduces Laser Module For 5G Wireless

Cooled coaxial DFB laser module features wide bandwidth above 6 GHz

Emcore, a provider of advanced mixed-signal optics for networks and defence systems, has introduced the Model 1998 cooled, coaxial DFB laser module for next-generation wireless fibre optic link applications.

The 1998 laser module features wide bandwidth above 6 GHz and is designed for 5G wireless, Distributed Antenna Systems (DAS), L-Band and S-Band signal distribution. The model 1998 and Emcore's complete line of lasers and optical receivers for wireless will be on display at the Mobile World Congress Americas (MWCA), September 12-14 at the Los Angeles Convention Center.

The migration to 5G wireless networks is fast approaching with Verizon's planned deployment of its fixed wireless 5G in up to five markets by the end of 2018, and 5G hotspots from AT&T expected by late 2018. Full-blown 5G smartphones are expected to be launched in the first half of 2019. Emcore's new 1998 is an ultra-linear, coaxial 1550 nm DFB laser module optimised for 5G wireless remoting fibre optic links. It is designed to enhance bandwidth and signal integrity for delivery of consistent, reliable wireless signals.

The laser is packaged in a compact, hermetic, cooled TOSA (Tunable Optical Sub-Assembly) with monitor photodiode, thermistor, TEC (Thermoelectric Cooler), optical isolator and flex circuit for integration into various transmitter configurations. It delivers superior optical performance over an enhanced temperature range of -40degC to +85degC.

"Our new 1998 laser builds upon Emcore's long history of high-performance designs for CATV, wireless and high-speed digital applications and will continue to raise the performance bar in linear fibre optic transmission for emerging 5G networks," said Gyo Shinozaki, VP of marketing for Emcore. "With bandwidth above 6 GHz, the 1998 will deliver maximum high-speed signal integrity for 5G, DAS and long-distance fibre optic link networks," added Shinozaki.

At MWCA, Emcore will also show its 1618A and 1718A, 6.5 GHz DFB laser modules and its 5200 Series 3 and 6.5 GHz fibre optic links. The 1618A and 1718A lasers are packaged in Emcore's classic 14-pin butterfly cooled laser form-factor and deliver highly-linear, superior optical performance at 1310 nm and 1550 nm wavelengths. The 5200 series are a compact, weatherproof fibre optic transmitter and receiver pair for Inter-Facility Link (IFL) applications where high-performance under demanding conditions is critical.
