Communications Systems Facility and

Cabling Infrastructure Design Guidelines

Forward

Central New Mexico Community College (CNM) has developed this document to assist our valued consultants and designers by establishing a set of “ground rules” when planning and designing new or renovated spaces and cabling infrastructure within and between our facilities.

This includes how we expect you to design a standard CNM communications room including provisions for electrical, mechanical and telecommunications systems and architectural finishes.

The cabling infrastructure includes equipment racks, cable tray, conduit, outlets, cabling and termination panels and they are also included in this document. This document, when used in conjunction with the CNM Communications Infrastructure Standards Manual (CISM) and the

CNM Standard Drawings, should provide the key and relevant information necessary to properly design to our new standards.

CABLE AND CABLE TERMINATION HARDWARE

This section discusses the general requirements for the backbone and horizontal distribution systems. It is the desire of CNM ITS to use a single manufacturer capable of providing all cable and cable termination hardware and to ensure the complete, installed system is covered under a comprehensive 25 year system warranty on all future projects.

The warranty is to be formally issued by the manufacturer at the completion of the project. The installation contractor must be a manufacturer certified installation firm and must provide a minimum of a 2 year warranty covering workmanship performed at CNM facilities.

3.1

Backbone System : The backbone consists of the inter- and intrabuilding cabling for voice and data systems including fiber optic and high-pair copper cables.

These systems are terminated on designated hardware in the ER/TR.

3.1.1.

Backbone Fiber: Interbuilding (ER to ER) backbone fiber will consist of

48 strands laser optimized singlemode fiber. Intrabuilding (ER to TR, TR to TR)) backbone fiber will consist of a hybrid style bundle including 12 strands of laser optimized 50 micron multimode fiber and 6 strands of singlemode fiber.

3.1.2.

Fiber Termination: Fiber will terminate using SC style connectors on 6 port adapter plates in fiber housings in communications racks. SC style ports will be used on the adapter plates (U.N.O). Fiber jumpers will vary from ST, SC and LC and will usually be procured and installed by CNM

ITS. Fiber housings will be mounted at the top of the rack in all installations.

3.1.3.

Backbone Copper: The interbuilding backbone copper will be sized based on the size of the building being served. CNM ITS will provide the specific pair count required for the interbuilding connectivity. However, the intrabuilding copper riser will be sized to: Need + 100 pairs. Need is based on the actual count estimated for that floor plus an additional 100

7






Cabling Infrastructure Design Guidelines pairs for buffer.

3.1.4.

Backbone Copper Termination: All interbuilding copper cable will terminate on multiple 100 pair protection blocks within the ER. From the protection blocks, a minimum of 100 pairs will be routed to a 48 port

Telco patch panel using amphenol connectivity. The riser cables will be routed up to the TR(s) and will terminate on 110 style termination blocks on the wall. A minimum of 100 pairs will be routed to a 48 port Telco patch panel using amphenol connectivity. If additional pairs are required, additional patch panels may be added.

3.2

Horizontal System

The horizontal system is composed of the ER/TR equipment rack or cabinet used to house the termination panels and wire management, the workstation outlet hardware including the faceplate and modular jacks, and the cable itself.

3.2.1 Equipment Rack: All racks will be full height, black equipment racks with predrilled EIA/TIA hole spacing. The rack must be modular to expand from a two post to a four post configuration. The rack must have an integral 6” channel as part of the frame.

3.2.2 Wire Management: All racks will be equipped with 4” x 6” vertical wire management installed back to back with solid covers to be installed on both sides of the rack. If multiple racks are ganged together, butt the frame of one rack up against the wire management of the adjoining rack.

Horizontal wire management will consist of 2 rack unit models with fingers and covers on the front and a mounting bar on the rear. Wire management on the plywood covered walls will use D-Ring style management with all rings mounted in straight lines.

OUTSIDE PLANT REQUIREMENTS

The following are general requirements for outside plant construction to be implemented on any new or renovation projects. No direct bury cabling is acceptable. As a general rule: All OSP cabling will be installed underground in conduit unless strictly unavoidable.

1.1.

Underground Conduit: Conduit systems shall adhere to TIA/EIA 569B standards, TIA/EIA 758 standards and shall accommodate the cabling requirements of TIA/EIA 568-B1, 568-B2 and 568 B-3 standards. Unless otherwise specified, all underground communications conduit shall be minimum 4 inch, schedule 40 PVC, buried a minimum of 24 inches, measured from the top of the conduit below finished grade. Warning tape is to be installed between 12”-

18” below the finished surface. All bends 45 degrees and larger shall be Rigid

Galvanized Steel (RGS) sweeps, 12 times the conduit diameter, or 48 inch radius, double wrapped with 10 mil PVC tape. Conduit ends shall be capped when work is in progress. RGS sweeps terminating in pull boxes shall be plugged. Mandrel testing of newly installed conduit systems is mandatory and to be witnessed by a member of CNM ITS staff. If the mandrel test fails, the Contractor shall repair or replace the affected conduit and re-test at no cost to CNM. All conduits not occupied by innerduct and tracer wire shall have an un-spliced, unknotted 2500 pound test (22 AWG) detectable mule tape installed and secured with 4 feet of slack at each pull box or termination point. Conduit must be installed in 20’ sections with no bends within 20’ of a manhole or handhole. Maximum linear

9






Cabling Infrastructure Design Guidelines conduit run is limited to 600 feet between manholes and 300 feet for handholes.

Discount maximum length with 100’ deduction per 90 degree bend and no more than 180 degrees of accumulated bends in run.

1.2.

Tracer Wire: Tracer wire (also known as locating wire) is being used more frequently by utility companies. Tracer wire is buried alongside when PVC conduit and fiber optic lines are installed underground, to assist in locating them for service and repairs. Tracer wire is to be installed in every new conduit run and will terminate within each manhole/handhole. The tracer wire shall be 12 AWG with HDPE sheath. Recommend Copperhead Reinforced Tracer Wire or equivalent.

1.3.

Manholes/Handholes : Manholes must be sized to accommodate a minimum of 8 conduits per side with traffic rated cover. Handholes are limited to maximum number of 6 conduits per side with traffic rated cover. All cabling passing through manhole/handhole must be linear in/out of box (Type A) with no 90 degree turns executed in the box. All direction changes must occur in conduit outside the box.

All penetrations into the box must be properly sealed after pull rope is installed.

A drain shall be provided in the bottom of each manhole and this drain should be connected to the storm drainage system if possible. Otherwise, provisions shall be made to install the manhole on a base of 6" of crushed stone or gravel to facilitate the drainage if no connection to the storm system is available.

A 3/4" hole shall be drilled thru the floor, 4" from the wall and a 5/8" X 8' ground rod shall be driven thru the hole until a minimum of 4"/maximum of 6" of the rod is protruding into the manhole. The ground rod shall be driven in the ground before the top section of the manhole is installed. The ground rod shall then be attached to the copper bonding ribbon by way of a #6 solid copper ground wire.

1.4.

Aerial Installations – Pole to Pole, Pole to Building, Building to Building :

Cabling to be installed from pole to pole and pole to building will follow industry standard methods and techniques in regards to attachment and location on pole

(standard hierarchy from top to bottom is power (Primary), power (Secondary), telephone, CATV and special applications such as this). Minimum make-ready

(span droop) distances must be maintained to ensure vehicle/rail clearance is maintained. Pole access must first be approved by pole owner prior to any attachment being made. Proof of approval for each pole must be provided to

CNM ITS for review. Maximum distance between poles is 300 feet. Use of steel strand for attaching high-pair copper cable is required. Use of messenger style cable with integral steel strand in/on jacket is acceptable for fiber optic, coax or

10






Cabling Infrastructure Design Guidelines twisted pair cables. Under no circumstances should any cable be installed without strain relief via messenger or steel strand.

Attachment to poles must use strain relief loop in cable to allow for expansion/contraction. Attachment to buildings may be roof mount or side mounted. For roof mounted applications use minimum 2-inch weatherhead and sleeve. Verify with CNM ITS the location of the penetration and then coordinate with CNM Facilities any roof warranty issues that may require the penetration to be performed by others. Under no circumstances will any penetrations to any building be performed without proper CNM ITS approval first. Attachment to the sides of buildings must use proper attachment technique. Penetration sleeve must be a minimum 2 inch sleeve angled downward from inside to outside to prevent rain/snow penetration. Cable must loop below lowest point of exterior sleeve before entering the sleeve. Sleeve must enter J-box w/cover on the interior before continuing into the ceiling/room space. Cable must transition from outside plant constructed cable to inside plant cable within 50 feet of penetration unless installed in conduit.

1.5.

Aerial Installations – Pole to Ground: Cabling that must transition from aerial to underground must have a service loop at the pole dead-end prior running down the pole. The cable should run down the pole on the opposite side of oncoming traffic when possible. The cabling must attach to the pole a minimum of every 24 inches using galvanized two hole straps and be run in a straight line down to the conduit stub up on the pole. The conduit must stub 12 inches above finished ground level. It is recommended to install a riser guard from the ground level to

~6 feet up the pole to prevent tampering. The guard should cover the conduit stub.

271323 - 11



F.

Optical Time Domain Reflectometer (OTDR) Testing

1.

After all terminations have been completed, tests will be conducted using an OTDR prior to testing with a power meter set (optical light source and optical meter). Contractor will test insertion loss of 850 nm and 1300 nm for Multimode cable; and at 1310 nm and 1550 nm wavelengths for Single-mode cable, for both directions through each connector pair using the OTDR. Use of an OTDR determines overall length and pinpoints loss locations along the segment being tested by indicating their distances from the source. The

Contractor will use the OTDR traces to assess the span attenuation that is necessary to evaluate the final acceptance tests utilizing the power meter test set(s). The power meter test measures overall attenuation of each span; this test also determines whether terminations are not within specified quality limits.

2.

OTDR Testing and the Span Loss Benchmark Calculation a.

Span Loss Benchmark Calculation. The estimated attenuation (loss) must be calculated for each fiber segment to determine a comparison value for the actual readings during the power meter test. This calculation is derived from the original reel tests performed at the time of cable acceptance. b.

In general, the OTDR traces must be interpreted to determine the length of each cable segment. Both ends of the span are terminated with an SC connector. In the following example the test is performed on multi mode fiber at 850nm. At the conclusion of the test, the trace for the span (end-to-end) is interpreted as follows:

Segment 1 is a fiber segment measured from termination to termination.

The benchmark calculation for the span is to be compared with the reading taken on the span with the power meter in final acceptance testing.



271323 - 12



3.

Power Meter Testing a.

All testing done with a light source and power meter shall be done such that the loss of any cables or connections used to interface the fiber to be tested to the instruments is measured and subtracted from the total loss of the fiber optic circuit. For testing the finished installation, the instrument(s) shall be "front ended" with SC connectors so that the testing includes the interface to the SC bulkheads in the fiber termination panels. b.

b. After termination of all the individual fibers, power meter readings will be taken.

The attenuation of readings must not be higher than the optimal attenuation loss. The optimal attenuation loss will be calculated using the manufacturer's factory certified fiber test reports (dB/km) converted to the actual installed lengths plus the attenuation losses for the SC connector of 0.75 dB per mated connector pair. The optimal attenuation losses shall be used for comparison with the end-to-end power loss test results prior to acceptance by CNM ITS. c.

c. If any reading is higher than 0.10 dB over the optimal attenuation loss, CNM ITS must be contacted for acceptance. If the loss is not acceptable, then the contractor must re-terminate the fiber to obtain acceptable loss levels. This will be done at the

Contractor's expense. Records of fiber loss must be maintained and provided for system acceptance by CNM ITS. d.

d. CNM ITS is to be notified at least 48 hours prior to testing to allow 100% observation at CNM ITS discretion. If CNM ITS confirms his intention to observe, a reasonable starting time will be agreed upon. Should CNM ITS not be present at the scheduled commencement time, the Contractor may begin testing as scheduled.

4.

Test Report Submittals a.

The Contractor shall submit test results on CD/DVD for review prior to CNM ITS acceptance of the Work. b.

Fiber optic cable test reports shall be delivered to CNM ITS for loss @ 1310nm and

1550nm for all single-mode fiber strands and 850nm and 1300nm for all multimode fiber strands. c.

Loss budget calculation shall be shown on the Fiber Optic Cable Test Report. d.

Substantial Completion will not be given without the final test results submitted and approved by CNM ITS.
