PHYSICAL NETWORK TOPOLOGY
The basic architecture of the information transport system should be based on a hierarchical star topology
utilizing Unshielded Twisted Pair and/or fiber optic media. The system must be based on open distribution
architecture so that existing equipment and facilities as well as future equipment from multiple vendors can
be supported by the proposed system. The system should have the ability to expand to support voice, video,
and emerging technologies.
Unless otherwise specified, copper should be used between the demarcation (T1) and the MC. Multimode
fiber should be used between MC and TC. The backbone must support Gigabit 1000BaseT if connected
with fiber. At least 3 Mbs if connected with a fixed wireless medium (laser, infrared, radio).
Administrative and instructional networks should be segregated. The vendor will provide a database or
spreadsheet on diskette of used IP numbers assigned to all devices. Printed network “as-built” maps (handdrawn maps will not be accepted) which show the hardware (with static IP addresses where appropriate),
cabling, and MC’s and TC’s will be provided by the vendor.
COPPER CABLING SPECIFICATIONS
Category 6 Unshielded Twisted Pair cable must meet or exceed the performance requirements as specified
in ANSI/EIA/TIA 568--B-2-1-2002 “Commercial Building Telecommunications Wiring Standard” and
EIA/TIA Telecommunications Systems Bulletin TSB-36, “additional cable Specifications for Unshielded
Twisted Pair Cables” and TIA/EIA TSB-40A, “Additional Transmission Specifications for Unshielded
Twisted Pair Connecting Hardware.” The District requires high speed data cabling conforming to enhanced
Category 5 for data requirements.
Cable Characteristics:
Cables shall be enhanced category 6 Unshielded Twisted Pair which is rated for at least 1Gbps transmission,
and should include jacks, blocks, patch panels, etc. that are rated for Gbps transmission. All UTP category-6
must be 4x0 FEP plenum construction approved for using air-handling spaces. Cable color should conform
to the district standard for data cable color, which is blue for all locations.
Jack and Outlet Specifications:
Each work area location must be equipped with a consistent arrangement of LAN communications outlets.
The faceplate must attach to a single gang electrical outlet box with a minimum capacity of four outlets.
Any vacant faceplate position shall be reserved for future growth and should have a blank inserted. The
District and the successful contractor will determine colors.
Outlet boxes must be installed so that they can be accessed easily and must not reside directly behind
furniture that would obstruct the jack.
The jacks used must conform to enhanced Category 6 specifications and to parameters set forth in EIA/TIA
568, TSB36 and TSB40A. All jacks and patch panels shall be configured to the T568B wiring scheme.
Patch panels shall be enhanced Category 6 compliant 110 interface in the back.
Seven feet rack with horizontal power strips with 10 outlets on both ends would be used
Testing and certification:
The contractor shall provide proof of communications wiring systems certification and testing certification.
Each communications outlet tested should include patch panel, patch cord, device jack and station side
cables. Testing must be “end-to-end.” All test results must be printed and show the following results:
Impedance (TDR), Line Mapping, Cable Length, DC ohms, Attenuation, and Near End Cross Talk (NEXT)
Test equipment must be power sum certified.
Cable Management:
Each equipment rack or wiring closet shall have horizontal and vertical cable management hardware to
ensure an organized and aesthetic installation to the District’s satisfaction. The cable management system
should be reliable and easy to service and maintain. The cables will be routed to avoid obstruction of ducts
and other material in the ceiling space. Cable trays or hooks should be used for the routing of all horizontal
cabling. All exposed cable (visible to those that use the building) should be enclosed in conduit or a quality
non-metallic surface raceway with NEMA standard screw-on or Snap-on Faceplate
Total cable length to each workstation is to be 295 feet maximum including jumpers; fifteen (15) feet of
extra coiled slack cable will be placed in the ceiling where the cable drops from the ceiling into the wall
above the patch panel.
General clearance requirements for UTP and STP cable are:
-- 4 feet from large motors or transformers
-- 1 foot from conduit and cables used for electrical power distribution
-- 1 foot minimum from fluorescent lights. Pathways should cross perpendicular
to fluorescent lights, conduit and cables used for electrical power distribution.
Note: These precautions may not be necessary for pathways that provide electromagnetic isolation between
horizontal cabling and sources of electromagnetic interference.
The use of fire stop is required for all penetrations in ceiling, floors, and fire noted walls in accordance with
all applicable codes and regulations and to the satisfaction of San Benito CISD.
FIBER OPTIC CABLING SPECIFICATIONS
All fibers must be indoor-outdoor rated plenum. There must be a cement cap on all fiber trenching. The
vendor will be responsible for capping off trench lines with black top. The vendor is responsible for
surveying the site for underground cables, pipes, etc.
Unless otherwise specified, for cable runs less than 2000 meters use multimode fiber 62.5/125m,
(CommScope, ATT, Siecor or equal). TIA/EIA-568A requires that the optical fiber meet the requirements
of ANSI/TIA/EIA-492AAAA, “Detail Specification for 62.5m Core Diameter/125m Cladding Diameter
Class Ia Graded-Index Multimode Optical Fibers.” For cable runs greater than 2000 meters use single mode
fiber. Single-mode optical fiber for backbone applications must meet the requirements of ANSI/TIA/EIA492BAAA, “Detail Specification for Class Iva Dispersion Unshifted Single-Mode Optical Fiber.”
Fiber Count - The District requires a minimum of 12-fiber strands for each cable run unless otherwise
specified.
Fiber Connectors - Each cable shall be terminated with ST-style ceramic connectors to TIA/EIA
specification and installed in fiber optic rack mount or wall mount termination cabinets.
Fiber Patchcords and Station Cables - Each fiber patchcord shall be multimode (62.5/125m) with STstyle duplex (length: 2 meters) unless otherwise specified.
Distribution Frame - Distribution enclosures and patch panels shall be either rack (19”) or wall mount
with ST-style bulkhead adapters.
Link Loss Specifications - Each fiber link less than or equal to 2 km shall be tested according to
ANSI’s Fiber Optic Test Procedures (FOTP) 171 and must be < 3.5 dB. An Optical Time Domain
Reflectometer (OTDR) trace must be done on links greater than 2 km. All fiber strands will be tested with
Light Source and Optical meter for maximum dB loss.
Exterior Building Connections - Fiber optic cable will be required on all exteriors building connections
and buildings that require more than one communications closet. The Ethernet standards dictate the
distance per horizontal connection is 90 meters and 100 meters total channel connection. Outdoor rated
PVC cable per NFP-70 may only extend 50 ft. from the penetration point into a plenum rated area. Any
non-plenum rated outdoor cable extending past the 50-ft. distance must be installed in EMT conduit. All
exterior buildings will be connected with a minimum of one 4-inch conduit with a minimum of three 1-inch
innerducts. All aerial fiber runs must be installed in UV rate black innerduct. The chosen installer must
provide any additional utility poles. The District prior to the start of the project will determine the location
and installation point of each pole.
TEST RESULTS AND SUPPORTING DOCUMENTATION
All testing and certification results are to be compiled in a table by location, cable number and strand or
color and provided with “as-built” drawings. Test results must also be provided in digital form. All
enhanced category 5 cables will be tested with TSB-67 certified level tester with two-way injector.
GENERAL CABLING REQUIREMENTS
All fiber optic cable will be enclosed in plenum innerduct (intrabuilding), metal conduit (interbuilding)
above ground), or PVC conduit (interbuilding below ground)
All conduit, innerduct, and cables will be secured to the building and installed in accordance with
industry standard practice. Innerduct shall be secured to the building structure above the suspended
ceiling. Category 6 cable UTP cable shall be bundled with wire ties and secured to the building
above the suspended ceiling.
Copper (UTP) runs in classrooms and offices or visible to those that use the building will be either in the
walls (wherever possible) or in a minimum 1 inch wire mold system or enclosed in conduit.
All wiremold systems and surface mounted boxes must be secured with anchors. Gluing to the wall as
the sole means of securing these items is unacceptable.
Label all patch panels with printed labels reflecting circuit I.D. Provide “as-built” prints with accurate
labeling of circuit I.D. and room number and segment lengths. Prefer CAD version 12 or greater. Label
the outside of each faceplate with a printed label circuit I.D. and each cable on both ends with selflaminating I.D. label. Labels will meet the legibility, defacement, adhesion and general exposure
requirements for indoor and outdoor use as specified in UL 969.
All racks used should include vertical 6 feet multi-outlets on both sides of the rack
Velcro tie wraps for support and management of UTP cable should be used instead of plastic or other
material.
Grounding and Bonding
– reference ANSI/TIA/EIA-607 standard
– minimum conductor size NO. 6 AWG
– establish connectivity to main building ground
When pulling cable through conduit, a pull string should remain for future use.
