The EMCORE Optiva Microwave Fiber Optic Transport System is a family of SNMP managed fiber optic transmitter and receivers that provide high-performance 0.05-40 Hz transport within the Optiva modular platform. The units can be used to construct transparent links for antenna remoting and other high-dynamic-range applications. The broad bandwidth supports applications such as electronic warfare systems. Other applications include delay lines and signal processing systems. Applications Satcom MW Antenna Signal Distribution EW Systems Broadband Delay-Line and Signal Processing Systems Frequency Distribution Systems Radar System Calibration Phased Array Antenna Systems, Interferometric Antenna Arrays Features 50 MHz-40 Hz Low RIN Source Laser Microprocessor-based Transmitter Control for Laser Bias, Modulator Bias & Link ain SNMP V.1 and RS-232 Monitor & Control Interface Compatible with EMCORE s Modular Optiva Platform DWDM Operation The standard transmitter provides a single optical output with up to 10 m optical output power. The system operates at a nominal wavelength of 1550 nm. Wavelength selected lasers on the ITU grid are also available to support multi-channel DWDM applications.
