High Definition HD SDI Repeater SDI Extender 270Mbps 1.485Gbps 2.97Gbps

Product Specification

1. Overview 

The SDI TX-RX series HD-SDI repeater is a high-definition SDI repeater that extends the transmission distance. It supports all SDI formats, such as SMPTE-292M (1.485 Gb/s, 1.485/1.001 Gbps), and all the SDI TX-RX series HD-SDI repeaters are equipped with SDI line equalizers, RECLOCK and line drivers. It complies with all SMPTE standards and meets the standards for broadcast television transmission.
The SDI TX-RX series HD-SDI repeater, this powerful repeater also includes two world-leading POC (power on cable) and DOC (data on cable) technologies, which can simultaneously provide 1.485G HD high-definition images and remote power supply and remote control via line on a 75-ohm BNC cable.
The SDI TX-RX series HD-SDI repeater can connect HD CCTV and RS485 control data and extend it up to 1 kilometer away through cable power supply and data on cable. Using a single coaxial cable to control the camera, each repeater segment distance can reach up to 200 meters (Belden 1694A). All repeaters do not require separate power supply, and the front-end cameras also do not need to be separately wired with RS485 or other control cables. 

2. Characteristics 

It supports video formats of standard definition SDI (270 Mbps), high definition HD-SDI (1.485 Gbps), and full high definition 3G-SDI (2.97 Gbps). 
Built-in cable equalizer Equilizer, clock regeneration circuit Reclocker and cable driver Cable Driver; 
Maximum cable length (Belden-B1694): SD supports 400m, HD supports 200m, 3G supports 140m; 
Outstanding SDI signal jitter suppression function, with nearly perfect eye diagram indicators; 
Each repeater is equipped with a power supply and an SDI signal format indicator, facilitating real-time monitoring by users. 
It is equipped with an ESD protection circuit, which can effectively prevent damage caused by static electricity. 
CE and FCC certified products. 
Unique characteristics 
The power supply is provided to all other repeaters at the front end from the monitoring room end (DVR side) via coaxial cables using the POC (power on cable) technology. 
At the same time, a 5M bandwidth data channel traveling in the opposite direction was debugged onto the video cable using the DOC (data on cable) technology. The control signal (RS485) could control the front-end cameras from the monitoring room end through the coaxial cable. 

3. Installation 

The SDITX-RX series HD-SDI repeaters can transmit HD-SDI signals up to 500 meters in each repeater segment (this depends on the quality of the cables). 

The repeater of the DVR (monitoring room end) connects the power supply and the RS485 control channel input.
