Digitally-Encoded 16-Channel Video System |
|
| DESCRIPTION
The DV-16V series product incorporate new digital
encoding technology. This fiber optic module transmits 16 channels of uncompressed 8-bit NTSC , PAL or SECAM video signals over one Singlemode or Multimode fiber. Lascomm’s digital product line incorporates plug-in personality circuit cards. The functionality of the DV-16V series are further enhanced by their compatibility with Meridian’s PC based SpectraSmart Network Management & Diagnostic Software System. SpectraSmart supervises the operating parameters of the transmission system such as the status on video levels, sync, digital carrier detect, voltages, temperatures, optical levels etc. See SpectraSmart brochure for further details.
Note: 10 bit version available. See DV-16W series. |
