VSB Modem with
Variable Data Rates from 1 to 30 Mbps |
|

Product Code: MM200MultiRateModem |
The V-Stream2 8VSB IF
Modulator/Demodulator is a 1 RU chassis using fifth generation
VSB technology. The unit accepts any input data rate from 1 to
30 Mbps (including ATSC 19.39 Mbps plus a T1 Data Pack) and
outputs a 7.5 MHz bandwidth 70 MHz RF signal using advanced 8VSB
modulation. When combined with an existing digital-ready STL
such as the Nucomm NuLinx series, the V-Stream2 8VSB Mod/Demod
provides a fully functional digital link for transporting such
digital signals as the ATSC 19.39 HDTV. The system is variable
rate capable and senses input data rates from 1 to 30 Mbps. The
V-Stream includes an integrated multiplexer, two ASI's or one
ASI and one SMPTE-310 I/O. The Data Pack includes a T1, 2 x
RS-232 and 8 logic inputs.
8VSB modulation offers excellent link performance and
reliability achieved from forward error correction and highly
efficient equalization. The forward error correction
automatically adjusts to adapt to local conditions.
The V-Stream system can be configured for simplex or duplex
operation and is available in hot-standby and space diversity
configurations. |
