[SML] HDMI

[FBC Tech Team]

Agreed with everything Michael said.

You *might* get lucky on a 25m run of passive cable, especially as you
appear to only need 1280x800 max resolution (higher resolution = shorter
passive distance limit), however, there are so many chances for things to
go wrong, and that's way over the suggested max limit of 15m for HD
sources, that you may as well do it right the first time. The length limit
is actually based on bandwidth carrying capability, not an actual
resolution, so that's just a thumbrule guideline.

We use the FSR HDMI Ribbon Cables at work and they're very nice, in between
MonoPrice and Celerity price-wise, and all 3 are rated up to 4K/UHD so
would serve you well in future upgrades. I've been meaning to try out the
MonoPrice varieties...it'll be interesting to see the results, as they sell
passive 100' HDMI cables as well which do not work. But, to be fair, their
literature suggests using an HDMI booster with them.

Alternately, the CAT5e/6/7 extenders are also very good, especially if you
specify the HDBaseT varieties. They're about equivalent in cost to the
fiber optic HDMI ribbon cables, however, as Michael said the fiber cables
are more fragile. If there's a chance of these cables being moved around
with any regularity, fiber types could break and you can't re-terminate
them yourself. With HDBaseT extenders, you can slice through a CAT5e/6/7
cable and have a new connector crimped on within 15 minutes, even if it's
mid-cable (recrimp both ends and use a RJ45 coupler to get through the
show). Even if you get a fiber HDBaseT extender, it's simple fiber...you
can reconnectorize that as well (harder, but do-able).

Another benefit of the HDBaseT extenders is they carry Audio, Video,
Ethernet, Control (RS232/IR) and Power (to power the receiver from the
transmitter so no AC adapter needed). Also, HDBaseT is a "standard" so you
can mix and match manufacturers.

Hope this helps,
Jeff
