Related Questions and Answers

Q: 1. 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: 2. Does the Talkback 4K come with the Fiber connector as pictured in your description for the Talkback 4K interface? Can I connect BMD Talkback 4K Fiber Connectors to the BMD Studio Fiber connector and have intercom at the BMD URSA Broadcaster Camera Fiber back?

A: The Talkback 4K does not include fiber SFP modules, they can be purchased separately: 3G - https://www.bhphotovideo.com/c/product/654839-REG/Blackmagic_Design_ADPT_3GBI_OPT_Adaptor_3G_BD_SFP.html 6G - https://www.bhphotovideo.com/c/product/1076394-REG/blackmagic_design_adpt_6gbi_opt_adapter_6g_bd.html 12G - https://www.bhphotovideo.com/c/product/1447935-REG/blackmagic_design_adpt_12gbi_opt_12g_bd_sfp_optical.html Yes, you can connect the Talkback 4K to the Studio Converter to get talkback on an URSA Broadcast camera with a Fiber Converter attached. You will need an ATEM switcher to pass the talkback channels through. Newer ATEM switchers have talkback built in, so you only need the Talkback 4K if you're using an older model. Consult your manual to see if your ATEM model has talkback built in.

Q: 3. does this come with the rackmount kit as shown in the picture?

A: The Rack Mount kit is a separate option.

Q: 4. Will a breakout cable be available for the tally intercom interface?

A: As requirements for this would be custom, you will need to make one yourself.

Q: 5. On the transmit end, will the SDI out work as a loop out of the SDI input, or is it strictly wired to only work with the fiber output?

A: The SDI Out is not a loop but an output from the fiber.

Q: 6. Needing to connect to existing Telex intercom system. Can I connect this directly to a Telex PS15 by building my own DB25 cable or do I need an interface (Telex DSI-2008) to make them work together?

A: The connections to the Fiber Converter require a 4 wire interface. You would need a 2 wire to 4 wire interface. Then build a custom cable with DB-25 for our end and whatever the 4 wire interface needs.

Q: 7. 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: 8. could one of the channels carry reference/genlock?

A: No only digital SDI Video signals. Reference is an analog signal.

Q: 9. Is there a single mode Fiber Camera Extension for black magic? If these are at a stadium and my control room is 1/2 mile away?

A: Currently there is no Blackmagic single mode fiber extension for the Blackmagic Design Studio Fiber Converter. You may wish to consider the Sony Single Mode Fiber Camera Extension Adapter BH #SOHDCE100 • MFR #HDCE100.

Q: 10. Will this accept TP-Link TL-SM5310-T 10G SFP+ to RJ45 Adapter Module?

A: No, the SFP+ to RJ45 adapter modules are not compatible with the Blackmagic Design Mini Converter Optical Fiber 12G-SDI.
