1-channel Video Optical Transmission
VOF-1000

VOF-1000 series Digital Video Optical Transmission transmit signals of 1-channel video, one-way or two-way audio/data, and switching capacity 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.

Features

Provide 1-channel video, 2 expansion slots (with 2 relative RJ45 connectors) RJ-45 connector：RS-485 module（including 2-channel one-way RS485 or 1-channel two-way RS485）, RS-422 module（including 2-channel RS422）, RS-232 module （including 2-channel RS232）, audio module （including 2-channel one-way audio or 1-channel two-way audio） and switching capacity module （4-channel switching value module） 1-channel Video Optical Transmission supports 1-channel reverse RS485 by default (when the first expansion slot PORT1 is in operation, default inverse RS485 is not available.)
