3G SDI over fiber extender 3G Mini ST Fiber Transceiver 10KM

OPTAV OV11SS-1FO-M3G 3G SDI over fiber extender delivers stable long-distance SDI signal transmission via single-mode ST fiber. Meanwhile, this compact metal transceiver adopts 1310nm DFB laser to lock clean broadcast-grade video signals up to 10 kilometers. In turn, it fully supports all mainstream SDI broadcast standards without signal distortion or frame loss. Besides, the unit supplies dual power options to match different on-site power wiring setups. Therefore, this 3G SDI over fiber extender fits broadcast studios, live event venues and monitoring control rooms perfectly. Furthermore, it uses tiny square metal housings to enable hidden mounting and rapid field deployment.

First of all, this 3G SDI over fiber extender complies with SMPTE professional broadcast protocols. Specifically, it supports SMPTE-424M 3G-SDI, SMPTE-292M HD-SDI and SMPTE-259M SD-SDI formats. Next, it runs at a fixed 2.97Gb/s data rate to carry full uncompressed broadcast video streams. To be precise, the built-in 1310nm DFB laser maintains consistent optical power across the whole transmission path. On top of that, fiber transmission completely blocks EMI and RFI interference from stage power and industrial equipment. As a result, broadcast crews receive flicker-free, lossless video feeds over long cable runs. Importantly, it retains full video sync and color accuracy for professional live production. For this reason, it eliminates picture noise and signal dropouts common with long copper SDI cables.

When it comes to optical transmission capacity, this transceiver relies exclusively on single-mode ST fiber links. Correspondingly, it reaches a maximum reliable extension distance of 10 kilometers for cross-building and large venue wiring. Even better, the standard ST optical port matches widely used single-mode fiber patch cords in AV broadcast projects. Meanwhile, fiber architecture cuts heavy copper cable weight and reduces cabinet clutter significantly. In effect, the DFB laser module delivers steady light output for consistent signal performance over the full 10KM range. In turn, users avoid costly signal repeaters for medium and long-distance broadcast layouts.

In terms of structural design, both transmitter and receiver adopt solid all-metal compact casings sized 20×20×50mm. Moreover, the TX unit features blue casing while the RX uses golden housing for instant visual identification. For starters, the hardware accepts two universal 5V power input methods: 3.5mm DC jack or micro USB cable. Equally, dual power options simplify power sourcing in fixed studios and temporary live shoots. Additionally, the small square form factor slides easily into rack gaps, cable conduits and equipment closets. Thereby, field technicians finish fiber and BNC wiring within minutes without extra mounting brackets.

Last but not least, this 3G SDI over fiber extender sustains continuous stable operation under extreme temperature ranges. In particular, it works reliably from -40°C to 85°C for outdoor live events, cold storage monitoring and hot equipment racks. In practice, the sealed metal shell resists temperature swings during cross-city transport and seasonal event use. It also handles standard indoor humidity levels without condensation damage to internal optical chips. Consequently, operators skip extra cooling or heating accessories for remote broadcast and monitoring equipment stations.
