Specification：
      Acorid’s digital VX8500-4V-4A-4D-E single-mode series is a high quality, 8-bit digital and non-compressed 4 channel video (8-ch system with WDM arrangement), audio (4), data (4) and Ethernet (contact closure (8)) transmission system over on one single-mode fiber up to 20-80 km distances.
      The system provides transparent transmission of PAL, NTSC or SECAM video signals as well as supporting formats such as S-Video for Y/C transmission.
      All units in the range have enhanced management functions for control, hardware/ signal alarms as well as having LED diagnostics for quick monitoring of signals and overall system operation.
      Management port allows local or remote (in-band connection via fiber) configuration and monitoring of VX8500-4V-4A-4D-E units. There are various models in the range depending on the requirements for video with either uni- or bi-directional data/audio/cc transmission is required.
      The OM610-4V-4A-4D-E is a high quality reliable product to fulfill your optical fiber video, data, audio & cc transmission requirements.
