2024 BICSI MEDIA CONNECTORSEXAM WITH CORRECT ANSWERS
How many types of balanced twisted-pair cables are recommended for use in
the horizontal cabling system? - CORRECT-ANSWERS2 types
- 4-Pair unshielded twisted-pair (UTP)
- 4-Pair screened/shielded twisted-pair
S/FTP Cabling Connectors - CORRECT-ANSWERSThe S/FTP cabling connectors
approved for use with category 7/class F and category 7A /class
FA cabling include
- RJ-type
- Non-RJ-type
Telecommunications signals can travel in many different ways - CORRECT-
ANSWERSOver radio waves
• Over cables as electrical signals
• As sound pulses
• As beams of light through the air
• As beams of light over an optical fiber
Coaxial Cable - CORRECT-ANSWERSPredominant coaxial cables include
Series-6, Series-11 and Series-59
- Unbalanced
- Consists of a centered inner conductor insulated from a surrounding outer
conductor and an overall jacket
- Used for computer networks, CATV and video systems
- Historically designated as radio grade (RG), now referred to as Series "X"
Series-6 Coaxial Cable - CORRECT-ANSWERS• Characteristic impedance of
75 ohm
• Uses an F or BNC connector
Series-11 U (Video Backbone) - CORRECT-ANSWERS• Characteristic
impedance of 75 ohm
• Typically configured with 18-14 AWG solid or stranded center conductor
• Uses an F or N connector
F Coaxial Connector - CORRECT-ANSWERS• Available as one- and two-piece
connectors or screw-on
• One-piece compression gaining favor due to higher bandwidth
, • Screw-on connectors are not recommended for commercial use
N Coaxial Connector - CORRECT-ANSWERS•N connectors are used in data,
radio and video applications
• Connector consists of a threaded coupling nut similar to an F connector
except larger
BNC Connector - CORRECT-ANSWERS• Named for its designers, Bayonet
Neill-Concelman has been in use since the 1940s
• Three types
- One-piece compression
- Three-piece (crimp)
- Screw-on—Not recommended for commercial applications
The horizontal cabling provided to each individual work area shall consist of -
CORRECT-ANSWERStelecommunications outlet/connectors connected to a 4-
pair 100-ohm balanced category 5e/class D minimum (category 6/class E or
higher recommended) cable
Common Copper Cable Fire Rating Designations - CORRECT-ANSWERSCMP =
Communications plenum
CMR = Communications riser
CMG = Communications General
CM = Communications
CMX = Communications limited
CMUC = Undercarpet communications
LSZH (LSF) = Low smoke zero halogen (low smoke and fume)
Four-pair Balanced Twisted-Pair Cable characteristics - CORRECT-ANSWERS-
Provides support for noise cancellation through conductor twisting
-Genrally has charactieristic impedance of 100 Ohm
-Conductor Sizes 22 AWG to 24 AWG
-overall sheath or jacket on each cable
Twisted-Pair Construction - CORRECT-ANSWERS• 4-pair cables used in voice
and data networks
• Outside diameter (OD) of 4-pair cables will vary
• Cable sizes range from 4 mm (015 inches) OD to 9 mm (0.35 inches) OD
Balanced Twisted-Pair Cabling Channel Performance - CORRECT-
ANSWERSCat 3/Class C = Cat 3 = 16 MHz
Cat 5/class D = Cat 5e = 100 MHz
Cat 6/class E = Cat 6 = 250 MHz
Cat 6A/class EA =Cat 6A =500 MHz
Cate 7/class F= N/A = 600 MHz
