8-Ch HD/SD-SDI Optical Transceiver (RV681P)
Overview
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, 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 RV681P includes desktop equipment and rack mounting chassis, the desktop equipment includes a transmitter named RV681PT and a receiver named RV681PR; 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 RV681PRK (hot- pluggable) and 1 management card, supports CLI command and SNMP_V1&V2 protocol to perform perfect management functions.
