Product Description

 8 Channel HD-SDI Video Optical Transceiver

The RV681N is a high performance, and reliable, 8-channel HD-SDI video optical transceiver, which perform real-time, loss-free and high-quality HD/SD-SDI transmission (audio embedded) over an optical line. Besides, RV681N provides one bi-directional RS485 data channel, and 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  8 Channel HD-SDI Video Optical Transceiver includes desktop equipment and rack mounting chassis, the desktop equipment includes a transmitter named RV681NT and a receiver named RV681NR; 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 RV681NRK (hot- pluggable) and 1 management card, supports CLI command and SNMP_V1&V2 protocol to perform perfect management functions.
