12G SDI Fiber Extender Mini ST Interface Singlemode 10KM SDI Optical Transceiver

OPTAV OV11SS-1FO-M12G 12G SDI Fiber Extender delivers lossless 4K UHD video transmission via single-mode ST fiber. Meanwhile, this compact metal transceiver adopts stable 1310nm DFB laser to extend uncompressed 12G-SDI signals up to 10 kilometers. In turn, it supports full SMPTE broadcast standards and backward compatibility with all mainstream SDI signal formats. Besides, the unit supplies dual 5V power input methods to fit fixed studios and temporary live shoots. Therefore, this 12G SDI Fiber Extender fits UHD broadcast studios, sports live events and post-production control rooms perfectly. Furthermore, it uses tiny black metal housings to enable hidden routing and fast on-site deployment.

First of all, this 12G SDI Fiber Extender complies with official SMPTE broadcast protocols. Specifically, it supports SMPTE ST-2081-1, ST 424, ST-292-1 and ST 259 industrial standards. Next, it runs at a full 11.88Gb/s data rate to carry native uncompressed 4K 12G-SDI video streams. To be precise, the built-in 1310nm DFB laser maintains consistent optical power across the full 10KM transmission range. On top of that, fiber transmission fully blocks EMI and RFI interference from stage power and industrial equipment. As a result, broadcast operators receive jitter-free, zero-loss UHD video feeds over long wiring runs. Importantly, it retains full color accuracy and video sync for professional 4K live production. For this reason, it eliminates picture noise and signal dropouts common with long coaxial SDI cables.

When it comes to signal compatibility, this 12G SDI Fiber Extender works seamlessly with legacy and modern broadcast signals. Correspondingly, it supports MADI, DVB-ASI, SD-SDI, HD-SDI, 3G-SDI and 6G UHD-SDI formats without extra adapters. Even better, the standard 75-ohm BNC electrical port matches all professional SDI cameras and switchers. Meanwhile, the ST fiber interface connects widely used single-mode ST fiber patch cords for AV projects. In effect, one single transceiver covers all existing studio SDI equipment to cut extra hardware costs. In turn, users upgrade their broadcast workflows without replacing current signal devices.

In terms of optical transmission capacity, this transceiver relies exclusively on single-mode ST fiber links. Correspondingly, it achieves reliable 10-kilometer signal extension for cross-building studios and large venue layouts. Even better, single-strand fiber design slashes heavy coaxial cable weight and tidies cabinet wiring spaces. Meanwhile, the stable DFB laser module delivers steady light output for consistent UHD signal performance over the full distance. In effect, users skip expensive signal repeaters for medium and long-distance broadcast layouts. In turn, field teams build clean, low-clutter fiber signal chains for 4K production.

In terms of structural design, both transmitter and receiver adopt solid black metal compact casings sized 20×20×50mm. Moreover, unified black housings simplify batch identification for multi-channel broadcast racks. For starters, the hardware accepts two universal 5V power input options: 3.5mm DC jack or micro USB cable. Equally, dual power modes support fixed studio wiring and portable live event power banks. Additionally, the slim square form factor fits tight cable conduits, rack gaps and hidden equipment closets. Thereby, technicians finish fiber and BNC wiring within minutes without extra mounting brackets.

Last but not least, this 12G SDI Fiber Extender sustains continuous stable operation under extreme temperature fluctuations. In particular, it works reliably from -40°C to 85°C for outdoor live events, hot equipment racks and cold storage monitoring rooms. In practice, the sealed metal shell resists temperature swings during cross-city transport and seasonal event deployment. It also withstands standard indoor humidity without condensation damage to internal optical chips. Consequently, operators skip extra cooling or heating accessories for remote broadcast and monitoring equipment stations.
