Another advantage of fiber is that you don’t have to worry about ground loops as you would have to with coaxial cables.

Everyone needs more fiber in their diet! Thanks for the helpful video.

[PaulDGreen]

I love using the DJP fiber setups. I also take Metamucil sometimes to keep me regular. With it’s great orange flavor, you’ll enjoy every cup, Metamucil, be good to your bowels!

[cozgreen]

You are a life-saver! Thank you very much for your time and expertise. I’m grateful for you.

[Snipersounds]

This was such a great video! I learned a lot! Thanks so much for sharing!
Do you guys have an online course please?

[MacAudio]

5:58 😂😂😂😂 I think Doug wanted a slightly stronger response than okay” 😂😂😂

[Dinnernator]

21:48 looms of these on almost every OB I've worked on 🤣 very informative video

[mwagoner]

Super great video! Hope to see more higher end videos. Liked also the level up stream team one.

Besides their expensive cables, what do you think of SMPTE? I know right now cause of covid they have some free webinars on some interesting stuff, but it's mostly education on the stuff THEY make and do.

I never thought that the fiber is just SDI through light.

Thanks!

Another Great Video. Just a few minor items.
1. Multi-mode fiber is NOT older, Single Mode was developed in 1970, Multi-mode wa created in the 1980's to allow 10Mbs ethernet to to go 2km using CHEAP LED transmitters compared to the expensive transmitters needed for single mode. Now that Single-mode SFPs are reasonable there is no reason for Multi-mode except for use in existing systems where they did not have enough foresight to install single-mode alongside the multi-mode for future proofing. By the way Multi-mode fiber has always been more expensive, just able to use cheaper transceivers!
2. SMPTE Composite cable does not have additional fibers for return channels, ALL SMPTE Composite cables have 2 Single-mode fibers, 2 Larger conductors for power, 2 small conductors for data. The dat wires are often used to negotiate the power level to be used on the power conductors and to ensure power is turned off when disconnected, the fibers are often (Grass Valley & Sony & ?) tu send 3G SDI to and from the camera, typically one fiber is used to send HD SDI (720P, 1080i, or 1080P) to the Base Station, the other fiber is commonly used to send TWO 1.5G signals to the camera, the Monitor return and an aux return ( Teleprompter, Talent Monitor, etc.) The Viewfinder return path has a small router in the base station that can send any of 3 or 4 SDI inputs to the viewfinder.
3. SMPTE Composite cable can be used for any single=mode purpose with a set of adapters, very handy if you go somewhere that is prewired with SMPTE cable.
4. Cameras set up for SMPTE can be used over a pair of single-mode fibers. This requires local camera power and often some adapters to spook the safety system to think the small wires are present.
5. you can make your own SMPTE cable with a pair of single mode fibers and 4 copper conductors - this is sometimes done when pre-wiring a building.
6. Most single mode fiber SFPs can be used on multi-mode fiber. The distance will be almost as far as a multi-mode SFP ( way shorter than a Single mode SFP) and a special "launch Cable" should be used on each transmitter side. Another option when you get somewhere that has something installed that is not ideal but may make the impossible possible.

Multimode fiber is a lot more forgiving when it comes to connection points. Singlemode connectors really need to be cleaned each time they mate, moreso than multimode.

[gotscottgreen]

This is very helpful. I will say the converters are a bit more expensive than BNC cables. but likely way better too.

[kerouac]

Just binged the trailer playlist and loved it, great job. We just ordered 6 Sony z280’s and I’m curious how you do com and return video if you are using the bmd 12g miniconverters.

[bobster]

Thanks, this is helpful in my search for SDI over fibre distribution. Not for cameras but just distribution. BMD don't seem to do a rack mount transmitter. The Teranex mini would be perfect but there isn't a fibre to SDI model.

[everwildvisualresearch]

2 Questions, Why LC connector over ST? And what basic fiber cleaning/testing tools would you recommend for a gig bag?

[applewizard]

My church is using 4x ~350’ SDI lines now to do a drive in style church with video in parking lot. The cables have about had it (8weeks of rough use) and I’m ready to replace them looking at using fiber, video came out with perfect timing. I’m looking at doing 150m of 6pair cable and 6x of the 3G fiber setups, any hesitations with that you see? 1080p59.94b

[Willb]

Thank you so much for your videos, most information on fiber has to do with networking so these are a life saver. Could you link me the armored patch cables you use?

[SAETACINEMA]

Where can I buy a 1000 foot fiber optic cable reel? something identical to what you show in your video?

[markhepi]

Hey Doug that was really informative. Couple of questions.

What’s the breakout box used in venue with the 24 strand fibre cable? Does it only feed video and not power Like cat 6 poe for ptz?
And how do you convert the OB trick side to capture the cameras into switcher. Cheers

[TechTuck]

So, if you have two fiber cassettes both at each end, one as a remote press box with all of the cameras going into it and then you have an MTP cable running that to another cassette that sends video to the Studio Converter...on the press box side, are you able to connect a switch with a fiber port into that cassette and have another switch like that on the other side so you can send internet and Dante over? That question may sound odd but I really don't know how to word it.

[wearethevoiceofthenorth]

If we are looking to use three to four cameras and what to use fiber and have an atem mini pro what else would we need for equipment we live ur videos and learn a lot not a big budget yet
