AVMatrix FE1121 12G-SDI Fiber Extender Set
SDI signal transmission up to 10 km via fiber optic
article number: 12725 | manufacturer number: FE1121-12G | EAN/UPC: 6971118000173
The AVMatrix FE1121 12G-SDI Fiber Extender Kit is a professional fiber optic extender solution for transmitting SDI video signals over long distances. The system supports 12G, 6G and 3G-SDI and enables the transmission of video signals up to 4K including embedded audio and metadata.
Signals can be transmitted over distances of up to around 10 km via a single-mode optical fiber. The set consists of a transmitter and a receiver, each of which is powered by a USB power supply. Both devices use SFP modules with LC connectors for optical signal transmission.
The transmitter also has an SDI loop-out output for local forwarding of the input signal, while the receiver provides two SDI outputs. An integrated SDI equalizer and re-clocking ensure stable signal quality even over long cable routes.

Questions & Answers▲
What is included with the AVMatrix FE1121?
The set consists of a transmitter and a receiver. Both devices are powered via a USB power supply and use SFP modules with LC connectors for optical signal transmission.
What maximum transmission distance is possible with the device?
Signals can be transmitted over distances of up to to about 10 km.
Which SDI formats are supported?
The system supports SD, HD, 3G, 6G and 12G-SDI as well as ASI. Detection and switching between formats occurs automatically.
Up to what video resolution can the signal be transmitted?
The system enables the transmission of video signals up to 4K, including embedded audio and Metadata.
Which type of fiber optic do I need for operation?
For operation, a single-mode fiber optic (single-mode) with LC connectors is required. The optical wavelength is 1310 nm.
How many SDI outputs does the receiver have?
The receiver provides two SDI outputs, the SD, HD, 3G, 6G and Support 12G-SDI and ASI with a terminating resistor of 75 ohms.
Does the transmitter have a loop-out output?
Yes, the transmitter has an SDI loop-out output, which allows local forwarding of the input signal to another device without interrupting the signal.
Are audio and metadata transmitted?
Yes, embedded audio and metadata are transmitted together with the video signal via the fiber optic connection transmitted.
What does the integrated SDI equalizer and re-clocking do?
The integrated SDI equalizer and re-clocking ensure stable signal quality even over long cable routes. With 12G-SDI, the equalizer is designed for cable lengths of up to 60 m.
Are the SFP modules included in the scope of delivery?
The transmitter and receiver each use an SFP module with an LC connector. The SFP modules are hot-pluggable. Please refer to the retailer's current product description to see whether they are included in the scope of delivery.
How are the transmitter and receiver supplied with power?
[Both devices, transmitter and receiver, are powered via a USB power supply
Is the device suitable for professional use?
Yes, the system is designed as a professional fiber optic extender solution and is suitable for applications in which SDI signals have to be transmitted stably and loss-free over long distances, for example in broadcast or Event productions.
