The SCM5000 is a high speed digital modem that offers the latest advances in error correction coding consistent with improved robustness and highly effective countermeasures to minimize the effects of dispersive fading. Unlike conventional modems, the occupied bandwidth of the SCM5000 can be adjusted by the user to fi t any microwave channel from 5 MHz to 40 MHz wide. Depending on channel bandwidth, the aggregate data rates can reach up to 170 Mbps.

Product Features

MRC's SCM5000 was specifi cally designed to provide the maximum in fl exibility for combined video and data payloads in a wide variety of point to applications. Most traditional modems employ a rigid architecture based on telecom interface hierarchy, forcing the user to restrict and frame video data at a DS-3/E3 or OC-3/STM-1 data rates and in fixed channel bandwidths.

While the SCM5000 does include the more popular telecom interface options, such as T1/E1, and DS3/E3, it also includes variable rate ASI interface options that can support any data speed the user wishes, up the maximum system throughput. Duplex models offer a 10/100 baseT option that can pass up 95 Mbps continuously. In addition, the occupied bandwidth of the IF output is continuously adjustable from 5 to 40 MHz, to allow full use of the licensed channel spectrum and maximize your data throughput.

The new SCM5000 demodulator includes an improved adaptive equalizer that effectively combats the effects of dispersive multipath fading that can occur on longer paths. For the ultimate in multipath protection, we have included a packet based space diversity switching option that constantly compares the packets received at each antenna, and allows only the error free packets to pass through.
