2-Channel HD-SDI Optical Transceiver (RV625P)

The 2-channel HD-SDI optical transceiver, performs real-time, loss-free and high-quality SDI transmission (2 embedded audio channels embedded in each SDI), and two bi-directional RS485/RS422/RS232 data (set by dip switch) over an optical line. Besides, it provides one 10M/100M Ethernet interface. It can be widely used in TV live broadcast, high-definition video conference, high-definition ...

Product Description


The 2-channel HD-SDI optical transceiver is designed for real-time, lossless, and high-quality SDI transmission with 2 embedded audio channels within each SDI stream. Additionally, it supports two bi-directional RS485/RS422/RS232 data channels (configurable via dip switch) over an optical line. The transceiver also features a 10M/100M Ethernet interface, making it versatile for applications such as TV live broadcast, high-definition video conferences, video monitoring, intelligent transportation systems, and public security setups.

This transceiver consists of a transmitter and receiver. The transmitter can be configured as desktop equipment or a 19-inch rack-mountable unit. On the other hand, the receiver is housed in a rack-mounting chassis with a width of 19 inches and a height of 4U. The receiver accommodates 16 hot-pluggable HD-SDI optical receive cards and one management card. This configuration supports CLI commands and SNMP_V1&V2 protocols, enabling seamless management functions.

2-Channel HD-SDI Optical Transceiver (RV625P)


The system adheres to SMPTE-292M HD-SDI and SMPTE-259M SD-SDI standards, supporting data rates of 1.485Gb/s and 270Mb/s. The transmitter includes two HD/SD-SDI inputs (BNC), one 10M/100M Ethernet interface, and two bi-directional asynchronous serial data channels. The receiver features two HD/SD-SDI outputs (BNC), one 10M/100M Ethernet interface, and two bi-directional asynchronous serial data channels.

Serial Data Channel Configuration:

The dip-switch allows individual configuration of each 2-channel bi-directional asynchronous serial data as RS485, RS422, or RS232.

Supported Video Formats:

The system supports various video formats, including 1080P@30,25,24, 29.97, 23.98, 1080I@60,50,59.94, 720P@60,50,30,25,24, 59.94, 29.97, 23.98, and 625i, 525i.
Output adjustments are made when the input is 1080P@29.97, 23.98, 1080I@59.94, 720P@59.94, 29.97, 23.98, resulting in 1080P@30, 24, 1080I@60, 720P@60, 30, 24.

Additional Features:

Integrated cable equalizer.
Embedded ESD and surge protection circuitry to prevent damage from static and thunder.
NOP (No Optical Signal) alarm indications, output status indicator, and input lock indicator.
APC (Automatic Power Control) circuit for stable optical power.

Management Interfaces:

Provides one RS232 management interface (CONSOLE) for CLI management.
Offers one common Ethernet management interface (EMU) and one cascade management interface (EMU-EX).
Supports SNMP_V1 and SNMP_V2 protocols.
