2-Ch HD/SD-SDI Optical Transceiver (RV621N)
The RV621N is a high performance, and reliable, 2-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, RV621N 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 RV621N includes desktop equipment and rack mounting chassis, the desktop equipment includes a transmitter named RV621NT and a receiver named RV621NR; The rack mounting chassis is used as the centralized HD-SDI receiver, adopts RV600C chassis with 19 inch width, 4U height, and with 16 2-channel HD-SDI optical receive card RV621NRK (hot- pluggable) and 1 management card, supports CLI command and SNMP_V1&V2 protocol to perform perfect management functions.
