2.2 Flashcards
provides an intermediate connection between the MDF and end user equipemtn on each floor and in eahc building
IDF
the ___________ standards pecify at least on IDF pre floor
ANSI/TIA
this area encompasses workstations, printers, and other networked devices and all the patch cables, wall jacks, and horizontal cabling necessary to connect these devices to a data room
work area
These come in in 2 or 4 post varieties, but 6 post are available.
racks
___________ is measured in rack units ( RU or U) with the industry standard being 42U tall, about 6 ft, half racks are 18U to 22U tall
rack height
____________ come in standard 19 inch frame, meaning that the front 19 inches wide.you might also come accross 23 inch racks
equipment racks
a relatively short length of cabling with connectors at both ends
patch cables
This is cabling that connects workstations to the closest data room and to switches housed in them
horizontal cabling
this is a copper based cable consists of one or more insulated twisted pair without shielding
UTP unshielded twisted pair
similar to unshielded twisted pair , but this one includes a metallic shielding surrounding the wires
STP shielded twisted pair
form of cable that contains one or several glass or plastic fibers in its core and comes in 2 types. Multi Mode fiber and Single Mode fiber
fiber optic cable
conists of cables or wireless links that provide interconnections between the entrance facility and MDF and between the MDF and IDF
backbone calbeing
when doing this , do not leave more then 1 inch of stripped cable before a twisted pair _________
termination
This is the radius of the maximum arc into which you can loop a cable without imparing data transmission
bend radius
the practice of verifying a segments of cables for reliability
continuity
