Emcore has introduced the 1618A and 1718A, 6.5GHz ultra-linear distributed feedback (DFB) laser modules operating at 1310nm and 1550nm, respectively. These new wide-bandwidth laser modules are designed and optimised for analogue wireless and distributed antenna systems (DAS) applications.
Network providers are building DAS systems in subway tunnels, sporting stadiums, high-speed trains and other public environments to address the increasing demand for wireless connectivity. The new 1618A and 1718A ultra-linear DFB 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 from –40°C to +85°C. These lasers are matched to 50Ω systems typical of wireless networks.
“Emcore's laser technology is world renowned and with these new models we continue to raise the performance bar in linear laser modules for the advanced communications networks,” said Henry Cheung, Emcore's senior product director. “With bandwidth up to 6.5GHz, the 1618A and 1718A deliver maximum high-speed signal integrity for wireless and DAS networks, and long-distance fibre-optic links.”
In addition to the new 1618A and 1718A lasers, Emcore has enhanced the performance of its 1742, 1550nm microwave DFB laser module by upgrading the bandwidth from 13GHz to 18GHz. The 1742 provides exceptional performance for linear fibre-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 or as a plug-in for rack-mounted systems.
