        The OTS-2 Series Satcom Band Fiber Optic Links are a family of SNMP man-          n  Satellite bands: C, X, DBS, Ku, Ka
        aged fiber optic transmitters and receivers that provide high-performance
        downlink and uplink transport within the modular Optiva platform. C, X,           n  Low RIN source laser
        DBS, Ku- and Ka-Band modules are available. Optiva satcom band modules            n  Microprocessor-based transmitter
        utilize EMCORE’s high-performance ultra-low Relative Intensity Noise (RIN)           control for laser bias, modulator
        source laser technology with high optical input power capable photodi-               bias and link gain
        odes, and feature microprocessor-based transmitter and receiver control for       n  DWDM cooled DFB laser, 10 dBm
        laser and modulator bias. Satcom band modules come with variable RF gain             output
        to provide consistent microwave link operations.
