        Optiva OTS-2 Series Microwave Band Fiber Optic Links                              Microwave Transport
        The OTS-2 Series Unamplified or Amplified (Tx, Rx Fixed Gain)
        Microwave Band Fiber Optic Links are a family of SNMP man-                        n  Low RIN source laser
        aged fiber optic transmitters and receivers that provide high-                    n  High-dynamic-range of
        performance 50 MHz – 40 GHz transport within the Optiva                             >110 dB-Hz 2/3
        modular platform. 18, 22 and 40 GHz options are available.
                                                                                          n  Microprocessor-based transmitter

        Optiva microwave units are tailored to the requirements of                          bias and link gain
        higher frequency applications such as microwave antenna signal
        distribution, electronic warfare systems, broadband delay lines,                  n  DWDM cooled DFB laser, 10 dBm
        signal processing, and phased array antennas. Utilizing EM-                         output
        CORE’s high-performance, ultra-low Relative Intensity Noise (RIN) source laser and high optical   n  SNMP and RS-232 monitoring and
        input power capable photodiodes, these modules provide high-dynamic-range. The system oper-  control
        ates at a nominal wavelength of 1550 nm. Wavelength selected lasers on the ITU grid are also
        available to support multichannel DWDM applications.
