EMCORE unveils DFB laser modules for wireless distributed antenna systems

EMCORE Corp. (NASDAQ: EMKR) has introduced two new distributed feedback (DFB) laser modules designed for analog wireless backhaul and distributed antenna system (DAS) applications.

The new 1764 DFB module for 1550-nm C-Band DWDM and 1615 device for 1310-nm will be previewed at ANGACOM, June 4-6 at the Cologne Germany Fairgrounds by EMCORE and EQ Photonics in hall 10.2, stand D038.

The increasing demands on wireless networks are creating greater need for deployment of cost-effective, integrated wireless DAS systems. Both the new 1764 and 1615 Series laser modules are designed, tested, and optimized specifically to support highly linearized wireless applications. These lasers are matched to 50-Ohm systems typical of wireless networks and have a wide operating temperature range of -40 degrees C to +85 degrees C for reliable performance in harsh environments and narrow transmitter designs. Both models have bandwidth up to 2.7 GHz.

The 1764 module features low adiabatic chirp to maximize signal quality over both short and long fiber lengths. The laser's linearity minimizes degradation of the broadcast signals caused by distortions and non-linear effects. The 1764 is available in all C-Band ITU grid wavelengths.

The 1615 DFB laser module for 1310 nm also delivers superior linearity and supports fiber lengths up to 10 km without dispersion issues, EMCORE asserts.

"We are seeing a growing market opportunity for adaptation of our highly-linear DFB laser technology for specialized wireless and DAS applications," said Jaime Reloj, vice president of business development for EMCORE. "Wireless systems providers are building systems in subway tunnels, massive stadiums, high-speed trains, and cruise ships. Our new DFB lasers for wireless applications integrate extremely well into these systems, enhancing bandwidth to help enable the delivery of consistent, reliable WiFi signals in areas where interference is high, or signals are normally weak."

The 1764 and 1615 DFB lasers also are compatible with the 4G LTE (Long-Term Evolution) standard for wireless high-speed data communications over mobile devices.
