4-Ch HD/SD-SDI Optical Transceiver (RV641N)

Overview

The RV641N is a high performance, and reliable, 4-channel HD-SDI video optical transceiver, which perform real-time, loss-free and high-quality HD/SD-SDI transmission(audio embedded) and one bi-directional RS485 data over an optical line. Besides, RV641N provides optional audio/contact closure/RS422/RS232 data transmission, which can be widely used in TV live broadcast, high-definition video conference, high-definition video monitoring, intelligent transportation system and public security system.

The RV641N includes desktop equipment and rack mounting chassis, the desktop equipment includes a transmitter named RV641NT and a receiver named RV641NR; The rack mounting chassis is used as the centralized HD-SDI receiver, adopts RV600C chassis with 19 inch width, 4U height, and with 16 HD-SDI optical receive card RV641NRK (hot- pluggable) and 1 management card, supports CLI command and SNMP_V1&V2 protocol to perform perfect management functions.
