8-Ch HD/SD-SDI Optical Transceiver (RV681P)

The RV681P is a high performance, and reliable, 8-channel HD-SDI optical transceiver, which perform real-time, loss-free and high-quality SDI transmission (two embedded audio channels for each SDI) and one bi-directional RS485 data over an optical line. Besides, RV681P provides one 10M/100M Ethernet interface and optional audio/contact closure/RS422/RS232 data transmission.

Product Description

SDI Optical Transceive

The SDI Optical Transceive is an advanced 8-channel HD-SDI optical transceiver renowned for its high performance and reliability. It excels in real-time, loss-free, and high-quality SDI transmission, supporting two embedded audio channels for each SDI channel. Additionally, it facilitates bi-directional RS485 data transmission over an optical line. The RV681P model also features a 10M/100M Ethernet interface and offers optional functionalities for audio, contact closure, RS422, and RS232 data transmission. This versatile solution finds applications in TV live broadcast, high-definition video conferences, video monitoring, intelligent transportation systems, and public security systems.

The SDI Optical Transceive is available in two configurations: desktop equipment and rack-mounted chassis. The desktop equipment comprises a transmitter (RV681PT) and a receiver (RV681PR). On the other hand, the rack-mounted chassis serves as a centralized HD-SDI receiver and employs the RV600C chassis, boasting a 19-inch width and 4U height. It accommodates 16 hot-pluggable HD-SDI optical receive cards (RV681PRK) and one management card. The system supports CLI command and SNMP_V1&V2 protocols, enabling seamless and comprehensive management functions.
