4-Ch HD/SD-SDI Optical Transceiver (RV641P)

The RV641P is a high performance, and reliable, 4-channel HD-SDI optical transceiver, which perform real-time, loss-free and high-quality SDI transmission (2 embedded audio channels embedded in each SDI), and one bi-directional RS485 data over an optical line. Besides, RV641P provides one 10M/100M Ethernet interface and optional audio/contact closure/RS422/RS232 data transmission.

Product Description


The RV641P stands out as a cutting-edge 4-channel HD-SDI optical transceiver celebrated for its outstanding performance and reliability. It excels in the real-time, lossless transmission of high-quality SDI signals, embedding 2 audio channels within each SDI stream. The transceiver also facilitates bi-directional RS485 data transfer over an optical line. Moreover, the RV641P is equipped with a 10M/100M Ethernet interface and provides optional support for audio, contact closure, RS422, and RS232 data transmission. This versatility makes it well-suited for a range of applications, including TV live broadcasts, high-definition video conferences, video monitoring, intelligent transportation systems, and public security setups.

The RV641P is offered in two configurations: a desktop setup comprising a transmitter (RV641PT) and a receiver (RV641PR), and a rack-mountable chassis designed for centralized HD-SDI reception. The rack-mountable system, housed within the RV600C chassis measuring 19 inches in width and 4U in height, accommodates 16 hot-pluggable HD-SDI optical receive cards (RV641PRK) and a management card. This configuration supports efficient management functionalities through CLI commands and SNMP_V1&V2 protocols, ensuring seamless operational control and monitoring.
