The Panavision fiber system that we used last summer was single channel of HD-SDI, which means running dual cables for 4:4:4--pretty silly, considering how much signal you can run through fiber.
Hrrrmmmm that may have been the system that Jim Hurwitz was telling me about. It's not a Telecast system BTW. The Copperhead will pass a 4:4:4 signal over a single fiber. Jim was also telling me about a Dual link Fiber they have that is more for redundancy that bandwidth.
Eric,
I just joined the Forum... Finally, the Holy Grail that we've been discussing for years is on its way! Over the next few months, we are rolling out the next generation of CopperHead technology, including several models that are Dual Link capable, each of which can work on the tactical fiber cable, or the hybrid cable to deliver power to the rig... More info to come when I can release it (but look out for CopperHead models 3400, DLV and Steadicam-friendly "Fiber Buddy").
Your Friend,
Jim

Would have thought that having less weight on the camera would have contributed more to keeping the post compacted (obviously as the camera weight increases, the gimbal raises until such time as one has to extend the post)...?
I found a pic of my Genesis/SSR setup--true enough this was a Primo show but looks to me like I've got the post plenty expanded, more than I would have liked. Obviously differences in sled weight could attribute to this (mine is a tad light with the Dionics) but still...just goes to show, we all attack these things differently.
Regarding the fiber, of course every fiber system is different and vary from carrying a plenthora of data and power (the Evertz is the only one I know of that does the latter) down to duplicating a single HD-SDI cable and no more, which means two separate fiber cables required to carry 4:4:4. I'm currently working with the Copperhead supplied through Panavision that does HD-SDI and camera data, but can't power the camera, unfortunately.
Hi Charles!
It has been a while! I have just joined the Forum, and noticed your post. Let me correct a slight misconception: all current CopperHead systems can, in fact, deliver power as well as the plethora of video, data and audio signals. However, it requires the addition of the "PowerPlus" accessory, which is in the inventory of many rental houses, but not ALL of them. In addition, you must use the heaveier, and less flexible "hybrid" cable (with copper wires in it) instead of the thin, flexible "tactical" fiber cable that you are using from Panavision.
You might be interested to know that we are rolling out the next generation of CopperHead technology over the next few months, including several models that are Dual Link capable, each of which can work on the tactical fiber cable, or the hybrid cable to deliver power to the rig... More info to come when I can release it (but look out for CopperHead models 3400, DLV and "Fiber Buddy").

Rich,
I am new to the Forum, and just found your post.. are you still using the CopperHead regularly? How is it working out for you? We are introducing the next generation of CopperHead technology over the next few months, including several models that are Dual Link capable, each of which can work on the lightweight tactical fiber cable, or a slightly thicker "hybrid" cable that can deliver power to the rig... More info to come when I can release it.
Look out for CopperHead models 3400, DLV and "Fiber Buddy."

Chris... lots of questions! Most of these can be answered by checking out the datasheet for the CopperHead G1, which can be found at http://www.telecast-fiber.com/Portals/42770/pdfs/ch_datasheet_4pg.pdf
To address them directly:
1) On the lightweight "tactical" fiber cable, you'll be limited to a maximum run of 30km. Yes, thirty kilometers. On the hybrid "powered" fiber, you can' tgo much longer than 2km. That should cover most steadicam applications... ;-)
2) Come see us at NAB next month!
3) Tactical fiber cable is military spec, battlefield-rated, and are tougher than any coax, triax or any other copper cables you've ever used. It is VERY flexible and resiliant. Power draw of the CopperHead Camera Unit is about 8 watts at 12VDC.
4) People do use the thicker Hybrid fiber cable with Steadicams. I'll leave it to them to weigh-in on whether it is practical or not. The Hybrid cable is not as tough as the tactical cables, but it is as robust as any coax you've used. There are two Power Supply options for the CopperHead with hybrid cable: "PowerPlus" (original CopperHead) and "PowerWafer" (original CopperHead and new CopperHead Series 3000). The PowerPlus requires an external power supply and delivers 150 Watts to the camera and accessories. The new PowerWafer uses a power supply built-in to the COpperHead base station, and delivers 95 watts to the camera and accessories.
