Section 4 - TELEVISION CABLE
4.1 GENERAL
- 4.1.1 GENERAL
Project specifications will
indicate who is to be responsible for furnishing, installing and
terminating the various types of communications cabling, outlets,
panels and other components specified in this section. Unless
otherwise noted, Telecommunications Center personnel or its
designee will be responsible.
- 4.1.2 LABELING
Television cables are to be
clearly identified via a painted section or by use of conduit
stickers indicating each conduit run; Yellow = television.
- 4.1.3 CABLE
4.1.3.1 Maximum cable distance must not
exceed 90 meters (295ft) or less. If the length of any cable run
(RG6) inside exceeds the 90-meter limitation, additional
communications equipment rooms shall be used. 4.1.3.2 Cable
type to be used is RG6,Shielded 60 % to 77 % braid 75-Ohm Coaxial
Cable. This can be found in Either Times Fiber or CommScope. Times
Fiber parts # - 02360 - T660-VB Standard. CommScope parts #
F677TSV. 4.1.3.3 RG-6 Connector, LRC AUGAT SNAP-N-SEAL Part #
SNS6. The two tools that will be needed to prep the cable and to
compress the connector on are, Compression tool Part #: SNSUTL.
The Coaxial cable Prep tool Part # CST596. 4.1.3.4 500 OR ½
MAIN LINE CABLE: The .500 cable will run from the basement to the
first floor where it will be cut leaving a 6 ft tail. The cable
leaving the first floor will also have a 6 ft tail this will be
repeated at each communications room up to the top floor where 1 -
6ft tail will end the process. This cable has a minimum bending
radius of 30 in. the reason for this is the aluminum shield will
break. 4.1.3.5 Coaxial Cable Part Numbers: The part # for the .500
Coaxial Cable installed inside the building from floor to floor is
Times Fiber is T10500JX or CommScope PIII 500 JCA. The part # for
cable installed outside the building from the pedestal to the
building is CommScope PIII 500 JCASP Television outlet
cable shall be RG-6/U type quad-shielded coaxial 75 ohm.
Television riser cables in multi-story buildings or
buildings with basement MCs and first floor TCs shall be .5 inch
rigid aluminum cable (hard-line) or single-mode fiber.
CATV outside plant cable for all tunnel and underground
conduit locations shall be .5 inch rigid aluminum cable
(hard-line) or single-mode fiber.
- 4.1.4 OUTLETS
Each TV outlet may provide
video capabilities and are generally terminated in a type F male
connector on a standard wall plate or incorporated into a
multi-port faceplate. Customer requirements will be conveyed to
Telecommunications Center. Each outlet shall be home
run to the nearest Telecommunication Closet.
4.2 VIDEO/PROJECTION DEVICES
- 4.2.1 GENERAL
Information Technology Instructional
Technology shall provide the specifications and cable parts for
projection devices and /or monitors. Projection devices are
either ceiling or table type mounts. In each case the conduit must
be connected to the front of the classroom or control area.
4.3 HIGH TECH CLASSROOMS
- 4.3.1 GENERAL
Information Technology
Instructional Technology shall provide the specifications for the
conduit installation and outlet(s) required for a room designated
as a High Tech Classroom. A High Tech Classroom outlet
will provide for the connection of voice, data, video, audio and
control devices.
- 4.3.2 LABELING
Each end of all cables (UTP,
coax, fiber, audio, etc.) and all pairs will be labeled at their
termination locations.
- 4.3.3 CONDUIT / OUTLET BOXES
In general, the
necessary conduit shall be provided as follows:
- Primary High Tech Classroom outlet box (4"X4"X3") in front
of room or teaching station to hall cable tray
- Two 1"Primary High Tech Classroom outlet to ceiling mounted
box (6"X6"X4") servicing video projector
- One 2" Primary Tech Classroom outlet to two audio outlet
boxes (standard outlet box) servicing stereo speakers and/or
wall mounted monitor
- One 3/4" per audio outlet
The location and
necessity of each will be determined during final design, based on
the intended function of the room. The room will always have one
primary High Tech Classroom outlet.
- 4.3.4 CABLE
The voice UTP cable shall each
be four (4) pair category 6, 400 Megahertz (minimum) cable.
The data and spare UTP cable shall be four (4) pair
category 6, 400 Megahertz (minimum) cable.
The video
cables will be RG6/U quadshield coax. The fiber will be
62.5/125 multimode duplex fiber - one (1) pair per outlet.
- 4.3.5 OUTLETS
The communication outlet will
contain a EIA/TIA-568B jack for voice, an EIA/TIA-568B jack for
data, an EIA/TIA-568B jack for spare, an F connector for received
video, 1 pair of fiber terminated in ST connectors for future data
and video requirements and a blank filler for future jack
requirements.
- 4.3.6 PATCH PANELS AND TERMINATIONS
The High
Tech Classroom cables shall be terminated in the MC or TC as
follows:
- Voice 4 pair category 6 - voice 66 CAT5e punch block
- Data 4 pair category 6 - data panel
- Spare 4 pair category 6 - data panel
- RG-6/U quad-shield coax - type F female connector, coiled
and wire tied or terminated on tap
- Data/Video fiber (1 pair) - Coiled and terminated ST in FIU.
(Fiber Interface Unit)
NOTE:
Voice category 6 shall be terminated to voice 66 CAT 5E punch block.
