STP Cable Termination
ATTENTION:
Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or
STP201 cable to link the switching transmitter and receiver. The DTP T USW 333 does
not work properly with these cables.
N'utilisez pas le câble AV Skew-Free UTP version améliorée UTP23SF d'Extron ou le
câble STP201 pour relier les produits XTP avec les émetteurs ou les récepteurs DTP.
Supported cables
The DTP T USW 333 is compatible with shielded twisted pair (STP) and unshielded twisted
pair (U/UTP) cable. However, Extron strongly recommends that you use STP cable to
achieve best performance.
Cable recommendations
Extron recommends using the following practices to achieve full transmission distances up
to 330 feet (100 meters) and reduce transmission errors.
•
Use the following Extron XTP DTP 24 STP cables and DTP 24 connectors for the best
performance:
XTP DTP 24/1000
•
XTP DTP 24P/1000 Plenum 1000 feet (305 meters) spool
•
XTP DTP 24 Plug
•
•
If not using XTP DTP 24 cable, at a minimum, Extron recommends 24 AWG, solid
conductor, STP cable with a minimum bandwidth of 400 MHz.
Terminate cables with shielded connectors to the TIA/EIA-T568B standard.
•
•
Use no more than two pass-through points, which may include patch points, punch
down connectors, couplers, and power injectors. If these pass-through points are
required, use Catagory 6 or 6a shielded couplers and punch down connectors.
NOTE: When using STP cable in bundles or conduits, consider the following:
•
Do not exceed 40% fill capacity in conduits.
•
Do not comb the cable for the first 20 meters, where cables are straightened,
aligned, and secured in tight bundles.
•
Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
•
Separate twisted pair cables from AC power cables.
