There's a couple ways you can go about this. One way has already been explained. The other is more of a a-la-carte method, but works with both the BM camera converter and other fiber converters.

It's built around this: http://www.studio-tech.com/product_m5132.html . This is a drop-in module (no exterior case) that is a POWERED 4 to 2-wire converter. It can power up to x3 RTS beltpacks and it works great!

There's also a box from Telecast that is a solely RTS over fiber solution: http://www.telecast-fiber.com/TR6442i-CommLink . Also works great! And is far easier obviously.

To Use with the BM Camera Converter with the Studio Tech interface: You only get 1 channel of RTS because the BM has only one intercom channel. You can add a second channel by adding parts of the next method. The next method also works with standard fiber to SDI converters.

You can accomplish this buy utilizing throwdown SDI to analog audio embedders and de-embedders.

(2) strands of fiber. (If you have a Tac-4, then you're double covered)
(2) BM Optical to SDI Converters. (Bi-directional)
(2) BM SDI to Analog Audio De-Embedders.
(2) BM Analog Audio to SDI Embedders.
(2) Studio Tech 5132's

Camera side:
Camera HD/SD-SDI -> Audio Embedder -> SDI to Optical Out.
Studio Tech 4-wire Ch-1 Out to Audio Embedder Ch-3 In. 4-wire Ch-2 Out to Audio Embedder Ch-4 In. Camera SDI embedded audio passes on Ch 1 and 2. (dip-switches on the embedder)
Optical In to SDI -> Audio De-Embedder.
Audio De-Embedder Ch-3 Out to Studio Tech 4-wire Ch-1 In. Audio De-Embedder Ch-4 Out to Studio Tech 4-wire Ch-2 In. (You can use channels 1 and 2 on the return path if desired.


For the truck side, just reverse the signal flow using the opposite setup.


However... For the price of putting all of this together... You might as well just purchase the: http://www.telecast-fiber.com/TR6442i-CommLink
