Model 907 video/digital multichannel system is applied to 12-channel high quality video analog signal and 64-channel bidirectional digital signal, which can be converted into 1-channel single-mode/multi-mode optical fiber transmission, or into 2-channel single-mode/multi-mode optical fiber transmission which can be automatically switched.

The Model 903 is modular in design and supports video signals in multiple formats. Adopting advanced fiber composite transmission technology (CWDM,DWDM), the system can be extended to 32-channel video and 256-channel digital, and also can transmit HDTV and HDSDI signals. It is suitable for long distance, high reliability, large capacity and high speed data communication up to 10km. Apply to medium - sized ROV, deep drag, etc.
