Model 903HD Multiplexer

HIGH DENSITY VIDEO/DATA MULTIPLEXER

The high density 903HD remote module provides the features of a fullsized subsea video/data multiplexer in a package of half the volume. This reduction enables installation in constrained spaces while supporting transmission of 4-8 high quality video channels and 8-16 bidirectional data channels over a single optical fiber. Since the 903HD uses the same FMB-X-2.5 fiber multiplexer boards (FMBs) as the standard 903, including CWDM versions, it supports singlemode or multimode fiber as well as dual fiber operation with automatic fiber switching. Data channels are easily configured with plug-in modules for various data formats. A standard 903 console module at the surface includes powerful diagnostics software with realtime display and logging of critical remote/console parameters.
