3G/HD SDI Converters
Portable 3G-SDI Video/RS485/2xTally over Fiber Optic Converters Adapter LC SFP Singlemode 10Km
PMD-3GSDI-D-2T-SFP
There is two version for option, one is 3G-SDI version which can support 3G/HD-SDI camera.
other one is 12G-SDI version which can support 12G/6G/3G/HD-SDI cameras.
other one is 12G-SDI version which can support 12G/6G/3G/HD-SDI cameras.
High end & Super professional Portable 1x3G-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 3G-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 3G-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.
Product Features
1. The SFP module is suitable to pathological code video, support for irregular bit-rate signals and pathological video modes, ensuring video image transmission stable.
2. The device supports clock recovery, can reduce signal jitter circuit, and process distorted signals.
3. The input has cable equalization to compensate for cable transmission losses.
4. Data complies with EIA RS-485 standard and is transparently transmitted.
5. Support 2-channel Tally signal, one Tally is red light, another Tally is green light.
6. Wide voltage DC 5~30V design, and provides 2 interface power supply modes, DC and Type C.
7. Single-mode optical fiber transfer distance can far reach to 10km.
