the model 5050a1mtx and model5075a1mrx product series provides high performance l-band communications interconnectivity in a hot swappable 4ru plug-in form factor. designed for antenna remoting and l-band satcom uplink & downlink rf transmission applications, the plug-in modules are interconnected using singlemode fiber optic cable to extended transmission distances beyond that of traditional coaxial cable. the receiver module is equipped with a digitally controlled attenuator which allows the operator to dynamically configure the optical channel to act as either an uplink or downlink transmission path. this capabilitiy provides operational flexibility to tailor the rf path performance over a range of optic loss budgets.
the transmitter uses a high efficiency distributed feedback (dfb) laser diode with an operating wavelength of 1310 nm that provides high dynamic range performance. the laser didoe's temperature stability is microprocessor controlled using a thermal electric cooler. the transmitter's microprocessor also provides embedded status monitoring of all critical parameters and communicates this information to a host computer using an rs-485 i/o interface. the i/o parameters include laser bias current, temperature and alarm status.
the receiver utilizes a high-speed, low distortion pin photodiode detector and also has an integrated microprocessor which provides the user with status monitoring. the i/o parameters include received optical power, temperature and alarm status.
