ANSWERS
Balanced twisted-pair cables have a nominal characteristic impedance of -
CORRECT-ANSWERS100 ohms at 100 MHz
Universal service order code (USOC) RJ61 pin/pair assignment - CORRECT-
ANSWERS1. White / Brown, Pair 4, T
2. White Green, Pair 3, T
3. White / Orange, Pair 2, T
4. Blue, Pair 1, R
5. White / Blue, Pair 1, T
6. Orange, Pair 2, R

66-style block - CORRECT-ANSWERSUsed for connecting voice applications
(e.g., PBX, key telephone systems, some LANs).
110-Style Hardware - CORRECT-ANSWERSused in both voice and data
cabling applications. Backbone cabling is commonly terminated on wall- or
rack-mounted 110 termination blocks in increments of 50, 100, or 300 pairs
as well as on a 900-pair wall mount.
BIX-Style Hardware - CORRECT-ANSWERSUnlike 110 hardware, which places
clips on top of the wiring block, BIX equipment is a one-piece pass-through
unit that is reversed in its mount after cable termination to expose the
opposite side and provide a cross-connect ield (Figure 1.19).
Coaxial cables have - CORRECT-ANSWERSan insulated (centrally located)
conductor surrounded by an overall metallic covering (see Figure 1.21).
Coaxial cable is used for - CORRECT-ANSWERScomputer networks,
community antenna TV (CATV),
video systems,
wireless applications
, The predominant coaxial cables are Series-6 and Series-11. Both of these
video cables have: - CORRECT-ANSWERS• A characteristic impedance of 75
ohm.
• Coated foil shield over the dielectric to shield against high frequencies.
• Braided shield over the coated foil to shield against low frequencies.
Series-6 coaxial cable is used for - CORRECT-ANSWERSvideo,
CATV,
security cameras
Series-6 coaxial cable has a - CORRECT-ANSWERSsolid-center conductor and
BNC or F connector.
Series-11 is used in - CORRECT-ANSWERSvideo backbone distribution
F connectors do not have - CORRECT-ANSWERScenter pin
N connectors are used in - CORRECT-ANSWERSdata, radio, and video
applications
N connectors have a - CORRECT-ANSWERScenter pin that must be installed
over the cable's center conductor. The N male connector uses a threaded
outer collar to mate with the female connector.
BNC connectors have - CORRECT-ANSWERSa center pin that must be
installed over the cable's center conductor and are used with RG59 (75 ohm)
coaxial cable.
Three types of BNC connectors - CORRECT-ANSWERS• Three-piece crimp.
• One-piece compression (recommended).
• Screw-on (not recommended)
Insulation - CORRECT-ANSWERSCopper wires must be physically separated
UTP - CORRECT-ANSWERSunshielded twisted-pair
screened/shielded cabling offers - CORRECT-ANSWERSa higher immunity to
EMI and may be used in areas susceptible to EMI, possibly eliminating the
need for metallic conduit in some environments.
F/FTP = - CORRECT-ANSWERSFoil-screened foil-screened twisted-pair
F/UTP = - CORRECT-ANSWERSFoil-screened unscreened twisted-pair
S/UTP = - CORRECT-ANSWERSBraid-screened unscreened twisted-pair
