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 Model 1998 cooled, coaxial distributed feedback (DFB) laser module for next-generation wireless fiber-optic link applications.

The 1998 laser module features wide bandwidth above 6GHz 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 are on display in booth #S-3227 at the Mobile World Congress Americas (MWCA) at the Los Angeles Convention Center (12-14 September).

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 first-half 2019. Emcore’s new 1998 is an ultra-linear, coaxial 1550nm DFB laser module optimized for 5G wireless remoting fiber-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 tunable optical sub-assembly (TOSA) with monitor photodiode, thermistor, thermoelectric cooler (TEC), optical isolator and flex circuit for integration into various transmitter configurations. It delivers what is claimed to be superior optical performance over an enhanced temperature range of -40°C to +85°C.

“Our new 1998 laser builds upon Emcore’s long history of high-performance designs for CATV, wireless and high-speed digital applications,” says Gyo Shinozaki, VP of marketing. “With bandwidth above 6GHz, the 1998 will deliver maximum high-speed signal integrity for 5G, DAS and long-distance fiber-optic link networks,” he adds.

At MWCA, Emcore is also showcasing its 1618A and 1718A 6.5GHz DFB laser modules and its 5200 Series 3GHz and 6.5GHz fiber-optic links. The 1618A and 1718A lasers are packaged in Emcore’s classic 14-pin butterfly cooled laser form-factor and deliver highly linear optical performance at 1310nm and 1550nm wavelengths. The 5200 Series comprises a compact, weatherproof fiber-optic transmitter and receiver pair for inter-facility link (IFL) applications where high performance under demanding conditions is critical.
