Extend your SDI signals over single-mode or multi-mode fiber optics with this Link Bridge Mini-3GHD-TR Fiber Optic 3G-SDI Transmitter. When combined with a 3G-SDI fiber receiver, SDI signals can be extended for miles (using single-mode cables) without any information degradation. The casing of the unit has a low profile to fit in tight equipment setups. Using a separate rackmount chassis, up to 12 transmitters can be organized in a patch bay. The panel connectors on the transmitter are a BNC SDI input, an ST-type fiber output for video I/O, and an integrated 5-pin XLR dongle for connecting to the included power supply. Like the BNC connector, the ST fiber connector offers a locking solution that will not come undone from cable strain. When not in use, the integrated metal cap covers the sensitive optical connection.

Related Questions and Answers

Q: 1. Will this work with Multi Mode fiber? Has anyone tried?

A: I have not tried this, but the adapter does not come with a SFP module so it would be worth a try. They recommend SMF because it loses less than MMF. I used 10Gtek 10G-SFP-LR modules and they work great. Blackmagic says it works with any SFP modules so I imagine it will work with MMF but no guarantees.

Q: 2. Can this run off a battery?

A: Yes. Comes with an AC to 12V DC power supply so you can run on 12V DC if you do not have reason to use any other voltage within the specified 6-36V DC. Just be careful not to mix the polarity, I am not sure its reverse polarity protected.

Q: 3. Does this support Talkback on the ATEM TV Studio 4K?

A: Yes it is compatible with the ATEM Talkback system.

Q: 4. After BMDs announcements at NAB2024 is this part deprecated in favor of the new 2110 IP Mini BiDirect 12G?

A: No, the Blackmagic Design Mini Converter Optical Fiber 12G-SDI will still have it's use cases. You should get the signal convertor that best suits your specific workflow.

Q: 5. I have 4 cameras. Two are HD-SDI and two are composite video. Can I attach all four cameras and toggle back and fourth between the inputs? One camera of each type would be connected to each side of the unit

A: Yes, you would be able to do that, but only if one SDI and one composite camera are connected to the corresponding inputs per single monitor. There are only one SDI and one composite input per side.

Q: 6. Does this aplifying the SDI signal or just transsfering?

A: This mini converter converts SDI to optical Fiber and will also convert optical fiber back to SDI. For long runs, you can have one at each end or directly connect fiber to many of the Blackmagic products.

Q: 7. does this convert from video over fiber to 12G SDI?

A: Yes, the Blackmagic Design Mini Converter Optical Fiber 12G-SDI converts video signals from SDI to Fiber and also works in the other direction, Fiber to SDI. The Blackmagic Design Mini Converter Optical Fiber 12G-SDI is made in the 12G format, meaning it supports 12G or lower SDI signals.

Q: 8. Does this unit pass metadata (timecode, record flag) to the output SDI stream?

A: We're afraid not. Metadata is not supported with this product.

Q: 9. How long of a run can this handle?

A: Depending on what type of fiber cable you are using, distances can be hundreds of feet to many miles.

Q: 10. Is available in 80km

A: This unit is rated for 6 miles / 9.6 km. Since 80km is almost 50 miles, this is not your answer.
