Finally a DVI- SDI converter

[Sven]

Kramer make cables with in-built transmitters and receivers. Those cables work. Magenta Research make Excellent DVI extenders that are very flexible. They can be used with Cat 6 or Fibre and even daisy chained. However you need to know a little what you are doing, e.g use the adequate fibre or Cat 6 cable and be aware of how do deal with EEID data.
I have used the Gefen boxes over 300m without problems. Current I use Magenta Research. Usually the cable is not up to standard, there is noise in the system (no power filters/ conditioning) or the EEID data gets confused somewhere because either DVI detectives are not used or not correctly programmed.

Magenta is what I'm considering. However, Doremi is my next choice. I am about done with Gefen though.

If you do get the Magenta boxes, just make sure youve got the fiber enabled in them. We had two that werent for some reason, and the factory said they would drop ship us new ones. Really annoying when you think you are covered for either UTP cable or Fiber......

I wasn't much for fibre until began reading and studying more.

I've been thinking copper and then something on another thread changed my mind. Christian makes some very good points which have started to change my point of view.

The thinklogical DVI extenders are absolutely brilliant...they cost more than Geffen but they are worth it.

...only need a single line of fiber to run to the other side of the extender (no Cat5e, no multiline fiber), however, they now have 2 fiber line outs...

...They don't require any Cat5e, just fiber which is very cheap now, just buy a spool and lamp kit. It is so cheap that you can literally throw it away at the end of the gig...

Thinkogical also has a relatively inexpensive DVI-D or Fiber routing system that can be routed via a web interface, Serial, or normally, by hand.

After seeing the Thinklogical products in action now for two shows, knowing how much savings it is, and how easy it was to get fiber feeds plugged in, having a build in DA for a preview monitor plus a spare fiber out where that in itself would take an additional ImagePro

These Thinklogical boxes look cool and match up to the Magenta. I would have leaned more towards Magenta since I have used them for other applications. I am still not sure so I am interested in feedback.

I have been using 50ft DVI cables (copper) without any noticable problems for a number of years. Low res only (l1024 or less)
