4K HDMI Optical Video Extender 10.2Gbps Mini HD Fiber Converter with RS232 and Audio Extension of Distances Up to 20km Over Single-Mode Single Fiber SFP Optical Transceiver

Can't beat the price. They work great! Many different uses but I send RS485 Dsan Speaker Timer data over fiber from FOH without running and spending time terminating a Cat5 cable...or 2. The SFPs are directional so mark which is transmitter and receiver. Note- SDI Rx is Data Tx and visa-versa. They were probably meant for the Security PTZ community, but I use them in broadcast, sports and events industries.

We buy quite a few of these for our business. Good Product Name brand good price no complaints.

Had the largest event we have ever done and needed an HDMI to Fiber Converter set. After doing my research I purchased these as they seemed like a good product. Could not get the signal through. The venues Fiber Optic Tech ran diagnostic's on their system. It was fine, so he ran a diagnostic on the signal we were providing and it too was fine. He then tested this equipment and the transmitter would not talk to the receiver. What an expensive piece of junk. You can bet it's going back!

Unit is well made with rock solid video and data transport. Power and video presence lights with a data activity flicker is very helpful for confirming connectivity. Units have been on-line 24/7 for a month. They are operating reliably.

I'm using this HDMI-fiber extender with a Panasonic LUMIX camera as the HDMI source. Intermittently the video just goes black for a few seconds. This happens while everything is just sitting there, but also can be triggered if I try to move or do anything with the camera (autofocus, stabilization, etc), or if the camera battery is <20%. I suspected that the extender was putting a momentary high load on the 5v rail, so I added a HDMI power inserter into the HDMI-IN of the transmitter... and boom, rock solid signal forever. Love the product and especially the small footprint, but they gotta get the 5v load, or the Hot Plug Detect, or whatever it is up to HDMI spec so that it stops resetting the connection with these battery-powered devices, like cameras. Note: if you go for my solution with the power inserter, make sure its supplying 5v to the MALE side (the extender side) not the female side (the camera side). I bought one that went the wrong way and had to crack it open and solder it the right way. **UPDATE** This device also has some minor issues with the RS-232 protocol. From Receiver to Transmitter it can go up to 250kb/s (maybe even higher), but in the other direction you can't go over 57k without getting timing issues and corruption. I saw it uses a MAX3232 chip internally, which is generally rated to 250kbps. I bypassed it on the circuit board to go right to the source signal (3.3v UART), and the behavior was the same. So this isn't really an issue with RS-232 but with the internal UART circuit. I tested this on two different pairs from the same manufacturer, and behavior was the same, so this is definitely a flaw in the design or maybe I'm just pushing it beyond the design spec. There's no listed ratings the RS-232 side channel in the manual, so I guess I can't complain too much?

Have used very cheap to very expensive extenders. And these are best for your $$$

The signal sending is high-speed, the device that I can remotely control my computer with my mouse and keyboard is of good quality. I didn't experience any lag in the signal

Connected to cat6 cable. Plugged into power on transmitter side. Only connected to cable on receiver end. About a 50 foot length. Picture and sound is perfect

CONFIABILIDAD, NO SE BATALLA NADA EN ENLAZAR

I don't regret buying it. A truly powerful SDI extender!Easy to connect and use, simple installation. Full HD video that is clear even over long fiber optic cables. Quite convenient to connect to a local monitor. It worked flawlessly when we used it for live streaming. We are very satisfied.

Ich setze den SDI-Transceiver jetzt seit ein paar Wochen für die Videoübertragung per Glasfaser ein. Hauptsächlich nutze ich ihn bei Veranstaltungen, bei denen ein stabiles 1080p-Signal über größere Distanzen gebraucht wird. Die Verbindung läuft zuverlässig und ohne Aussetzer, auch bei längeren Strecken (bei mir ca. 15 km). Die Installation war unkompliziert – Kabel rein, Strom drauf, und das Signal war direkt da. Praktisch ist auch der SDI-Loop-Out, den ich für die lokale Bildkontrolle nutze. Die Rückleitung über RS485 funktioniert bei mir ebenfalls ohne Probleme. Was mir außerdem positiv aufgefallen ist: Das Gerät kommt mit verschiedenen SDI-Kameras klar, ohne dass ich viel einstellen musste. Auch Hot-Plugging hat bisher problemlos funktioniert. Die Verarbeitung wirkt solide, das Gehäuse ist kompakt und macht einen langlebigen Eindruck. Im Großen und Ganzen: Das Gerät erfüllt seinen Zweck zuverlässig. Wer ein einfaches und funktionierendes System für SDI-Übertragung über Glasfaser sucht, kann damit gut arbeiten.

Sehr hochwertiger Extender, den wir bereits zweimalig - für einen längeren Zeitraum - in Verwendung hatten. Hochprofessionelles Tool für eine verlustfreie Übertragung von Video- und Audiosignalen über große Distanzen (Gartenbereich, Firmengelände, etc.) Funktioniert auch ohne plötzliche Abbrüche oder gar Verbindungsschwierigkeiten. Nimmt auch kaum Platz (Mini Größe) ein und somit auch einfach mitnehmbar. Gehäuse sehr gut verarbeitet. Sind rundum zufrieden!

Dieser Mini 3G‑SDI Video Extender ist der ideale Begleiter für professionelle Broadcast‑ oder Studioanwendungen. Er verlängert 1080p SDI‑Signale via Single‑Mode‑Glasfaser auf bis zu 20 km – ohne Qualitätsverluste. Der integrierte SDI‑Loop‑Ausgang ermöglicht parallele Signalverteilung, während Tally‑ oder Reverse‑RS485‑Funktionen Kommunikation oder Steuerung ermöglichen. Das kompakte Gehäuse ist robust und eignet sich perfekt für mobile Installationen oder feste Verkabelungen mittels DIN‑Rail oder Wandhalterung. Die Handhabung ist selbsterklärend: SDI‑Quelle anschließen, Glasfaser‑Kupplung verbinden. Und sofort steht ein sauberes, stabiles Bild.
