Description
OPTAV OV12SS-1FO-12G 12G SDI Fiber Extender with Loop Out delivers lossless 4K@60Hz UHD video transmission over single-mode LC fiber. Meanwhile, this dual-port metal transceiver integrates built-in re-clocker and carries extra RS485 & tally light signals in one fiber line. In turn, it extends complete 12G-SDI broadcast signals steadily up to 10 kilometers without signal loss or frame jitter. Besides, the transmitter adds SDI loop out port and receiver outputs dual SDI streams to simplify multi-monitor layout. Therefore, this 12G SDI Fiber Extender with Loop Out fits broadcast camera control, live sports production and post-production studios perfectly. Furthermore, it adopts slim black metal housing to support neat rack installation and fast on-site wiring.
Core Advantages of 12G SDI Fiber Extender with Loop Out
1. Full SMPTE Protocol Support & Built-In Re-Clocker
First of all, this 12G SDI Fiber Extender with Loop Out complies with full mainstream SMPTE broadcast standards. Specifically, it supports ST-2082-1(12G), ST-2081-1(6G), ST-424(3G), ST-292(HD) and ST-259(SD) signal formats. Next, the integrated re-clocker locks all standard SMPTE rates including 11.88Gbps, 5.94Gbps, 2.97Gbps and lower sub-rates. To be precise, the internal chip stabilizes signal timing to eliminate jitter after long-distance fiber transmission. On top of that, it natively handles DVB-ASI and AES10 MADI audio data for all-in-one broadcast signal transport. As a result, camera crews get synchronized, clean 4K video feeds without extra signal correction gear. Importantly, it directly pairs with standard 12G/6G/3G-SDI broadcast cameras out of the box. For this reason, it cuts extra signal processors and lowers overall studio equipment costs.
2. Unique Loop Out TX & Dual SDI Output RX Design
When it comes to multi-signal distribution, this transceiver solves split monitoring demands with exclusive dual-port layout. Correspondingly, the transmitter equips an SDI loop out port to feed local on-camera monitors without splitters. Even better, the receiver delivers two independent synchronous SDI outputs for mixer and remote display walls at the same time. Meanwhile, the design removes external signal splitters to reduce wiring clutter and signal attenuation risks. In effect, one fiber link completes camera feed, local preview and remote multi-screen display simultaneously. In turn, live broadcast teams build compact, efficient signal chains for multi-view production workflows.
3. Bidirectional RS485 & Tally Light Pass-Through
In terms of auxiliary signal transmission, this unit carries control signals alongside video through one single fiber cable. Correspondingly, it supports bidirectional RS485 for remote camera PTZ control and tally light signal transmission. Even better, operators adjust camera parameters and trigger tally indicators over the full 10KM fiber range. Meanwhile, the combined signal transport avoids running separate control cables for camera and lighting gear. In effect, users simplify field wiring and cut cable laying time for outdoor live events. In turn, broadcast engineers finish full camera control setup within minutes without extra fiber runs.
4. 10KM Single-Mode LC Fiber Stable Transmission
In terms of optical performance, this extender uses single-mode LC fiber and 1310nm DFB laser for long-distance extension. Correspondingly, it reaches a maximum reliable transmission distance of 10 kilometers for cross-building studio layouts and large venue broadcasts. Even better, LC fiber ports match standard broadcast fiber patch cords widely used in professional AV projects. Meanwhile, fiber transmission fully isolates EMI and RFI interference from stage power and industrial equipment. In effect, operators skip costly signal repeaters for medium and long-distance camera signal extension. In turn, teams maintain zero-loss 4K 3840×2160@60Hz video across the whole fiber run.
5. Slim Metal Housing & Wide Operating Temperature Range
Last but not least, this 12G SDI Fiber Extender with Loop Out adopts compact black metal casing sized 85×50×18mm for easy deployment. Moreover, the uniform slim shape fits equipment racks, camera stations and hidden cable conduits seamlessly. For starters, the whole system runs on standard 5V micro USB power supply for portable and fixed studio use. Equally, the solid metal shell boosts heat dissipation and electromagnetic shielding performance. Additionally, it works reliably in extreme temperatures from -40°C to 85°C for outdoor shoots and hot equipment rooms. Thereby, the hardware delivers stable round-the-clock operation for year-round broadcast production.
