3540A 5 GHz DFB Laser Transmitters DATASHEET | NOVEMBER 2013 MICROWAVE The 3540A Distributed Feedback (DFB) laser transmitters provide exceptional performance for linear fiber optics communications in very wide bandwidth applications. EMCORE’s linear fiber optics are excellent alternative to using coaxial cable systems to transmit 10 MHz to 5 GHz signals. They offer significant improvements in reliability in microwave communications networks by transmitting the RF signal in its original format. As a result of these properties, these microwave DFB laser transmitters provide significant improvements in signal quality for a wide variety of applications including antenna remoting, timing and reference signal distribution, telemetry, measurement and delay lines. Applications Antenna Remoting Cellular and PCS Networks Military Triband Communications The 3540A is available as a flange-mount design for extreme environments or as a plug-in for integration with EMCORE’s System 10000 rack-mountable chassis and power supplies. Electronics within the flange-mount and plug-in transmitters control the laser temperature and DC bias current and provide warnings whenever the temperature or power deviates from their intended levels, thus providing a self-regulating, fully-integrated microwave product. These units provide high-quality noise performance in sensitive optical links.
