High end & Super professional Portable 1x12G/3G-SDI Video /RS485/2xTally over Fiber Optic Converters, Highly recommended !

Most advantage: The device supports clock recovery, it can reduce signal jitter circuit, and process distorted signals, make a super stable signal transmission. it is much better than ordinary units in low costs in current marketing. 

Product Introduction 

This Portable 12G-SDI Video Multi-service Optical Fiber Transmission System was developed by our company and has independent intellectual property rights. It combines the advantages of similar products from both domestic and international markets with the actual demands of the market. 

This sdi over fiber device to transmit 1-channel of forward directional 12G-SDI (from TX to RX) video signal, 1-channel reverse directional RS485 data (from RX to TXX) signal and 2-channel reverse directional tally function (one red light and one green light) with lossless, delay-free transmission of up to 20 km through a single optical fibre. The device has a wide voltage power supply design of 5–30 V and provides two power supply modes: DC 5.5*2.1 and a USB Type-C interface. This makes it more flexible and convenient for use in various scenarios.

The  optical SFP module and core circuit are made of imported components and feature a multi-layer board design. The circuit is reliable and stable with strong anti-interference capabilities. The module is easy to install and debug, maintenance-free and designed to operate over a wide temperature range. As the transmission medium is optical fibre, it has excellent performance and is resistant to high temperatures and cold weather. It can effectively prevent strong electromagnetic radiation interference, lightning strikes, and power surges, greatly improving stability and reliability.

Attention

Lightning protection, static electricity and grounding:

It is recommended that when install the device, consideration should be given to the impact of grounding by lightning, and take prevention measures. Strong static electricity will damage the optical device and data chip in the equipment. It is recommended that when plug/unplug the data port of the optical converter, please disconnect the power supply of the optical converter first.

Fiber and optical components:

Be careful when plugging the optical fiber as optical components of the optical converter is very fragile, and it should avoid causing damage to the optical components. It should be noted that the light source produced by the optical components of the optical converter will be harmful to eyes, so do not have direct eye contact with the optical components of optical converter. If you need to detect the optical power of the optical converter, please use the optical power meter.

Equipment and installation procedures:

（1）Optical fiber installation: please carefully insert the optical fiber into the optical fiber interface of the optical terminal after confirming that the optical fiber link meets the installation requirements.

（2）Power amplifier audio signal cannot be directly given to the transmitter, which will lead to the burning machine.

（3）Equipment installation: The equipment can be distinguished between transmitter and receiver, and it is stated clearly on the label and printed on the chassis of the equipment.
