8-channel Video Optical Transmission
VOF-8000
G.SHDSL Modem

VOF-8000 series Digital Video Optical Transmission transmit signals of 8-channel video, one-way or two-way audio/data, switching capacity and 1-channel Ethernet through an optical fiber simultaneously. The series products are divided into standalone type and card type. The video quality meets the broadcast standards, and the quality of audio reaches the CD level. The series are video access products with carrier class, supporting RS-232, RS-422 & RS-485 (with 2/4 lines) and other data communication formats and signal input of switching capacity. All optical and electrical interfaces meet the international standards. The products are designed with electromagnetic compatibility, lightening protection, electrostatic prevention, high stability and reliability, and are available for working in various complex and poor conditions. In addition, the products has advanced network management and monitoring function. The products perfectly meet the carrier-class management requirements.
