Twisted pair (TP) cable advantages

Twisted pair cable is much smaller, lighter, more ﬂexible, and less expensive than

coaxial cable. These TP products make cable runs simpler and less cumbersome.

Termination of the cable with RJ-45 connectors is simple, quick, and economical.

Transmission distances

The maximum distances are determined by the frequency and resolution of the

video signal being routed and by which MTPX Plus inputs and outputs (TP or

local) are in the full (video source to display) routing path. The tables below and

on the next page specify the recommended maximum transmission distances

usingExtronEnhancedSkew-FreeA/VUTPcableorUTPCAT5,5e,or6cable,

terminated with RJ-45 connectors.

acceptable, but less preferable. We also recommend the use of preterminated

and tested cables. Cables terminated on site should be tested before use to

ensure that they comply with Category 5 speciﬁcations.

line consisting of a single transmitter, the switcher, and receiver and for a

transmission line that encompasses a transmission daisy chain. For example,

the maximum suggested output range (MTPX Plus TP output to MTP

receiver)for1024x768videois450’(135m),whetherthetransmissionline

consists of the switcher and a single receiver or the switcher and three daisy-

chained receivers. This range can be extended to 500’ if the output is one that

has the Pre-Peak function and the function is turned on.

• Fordaisy-chainedunits,therstreceiverinthechainshouldbeatleast50’

(15 m) from the switcher when the Pre-Peak feature is on.

• Fordaisy-chainedunits,anyreceiverinthechaincloserthan350’(105m)

may experience some form of over-peaking when the Pre-Peak switch is on.

An overpeaked image may appear bloomed.
