2.2 COMPONENTS

2.2.1 Optical Fibers

2.2.1.1 General

Coat optical fibers with a suitable material to preserve the intrinsic strength of the glass. The outside diameter of the glass-cladded fiber is nominally 125 microns, and concentric with the fiber core. Ensure optical fibers meet TIA-455-78-B, and TIA-455-177.

2.2.1.2 50 Micron Multimode Fibers

Use conductors that are multimode, graded index, solid glass waveguides with a nominal core diameter of 50 microns. Ensure the fiber has transmission windows centered at 850 and 1300 nanometer wavelengths, with a numerical aperture minimum of 0.20. The attenuation at 850 nanometers is

3.5 dB/Km or less. The attenuation at 1300 nanometers is 1.5 dB/Km or less. For both transmission windows, the minimum bandwidth is 500 MHz-Km.

Certify the fibers to meet TIA/EIA-455-204 and TIA-455-58.

2.2.1.3 8.3 Micron Single-Mode Fibers

Use conductors that are single-mode, solid glass waveguides with a nominal core diameter of 8.3 microns. Ensure the fiber has a transmission windows centered at 1310 and 1550 nanometer wavelengths with a numerical aperture minimum of 0.10. The attenuation for inside cable at 1310 and 1550 nanometers is 1.0 dB/Km or less. The attenuation for outside cable at 1310 and 1550 nanometers is 0.5 dB/Km or less. Certify the fibers to meet

ANSI/TIA-455-80C.

2.2.2 Cross-Connects

2.2.2.1 Patch Panels

Install patch panels as a complete system of components by a single manufacturer; provide termination, splice storage, routing, radius limiting, cable fastening, storage, and cross-connection. Ensure patch panel connectors and couplers are the same type and configuration as used elsewhere in the system. Patch panels are a 19-inch rack mount type as shown.

2.2.2.2 Patch Cords

Provide patch cord cable assemblies consisting of factory connector-terminated flexible optical fiber cable with connectors of the same type as used elsewhere in the system. Optical fiber is the same type as used elsewhere in the system. Install patch cords as complete assemblies from manufacturer's standard products.

2.3 SYSTEM REQUIREMENTS

2.3.1 Receiver Dynamic Range

Ensure the dynamic range of receivers is large enough to accommodate both the worst-case, minimum receiver flux density, and the maximum possible receiver flux density, with a range of at least 15 dB. Where required, use optical attenuators to force the FO link power to fall within the receiver dynamic range.

SECTION 27 21 10.00 40 Page 4

2.4 ACCESSORIES

2.4.1 Fusion Splices

Use a portable, fully automatic, and compact fusion splicer, suitable for fusion splicing all types of telecommunication grade optical fibers and individual fibers as well as cables containing multiple optical fibers.

Ensure the fusion splicer is capable of operation under various environmental conditions (e.g., temperature, humidity, altitude, etc.) for all types of optical cable deployments. Start the automatic splicing process by pressing one button and can be interrupted at any time.

Alternatively, make available semi-automatic (step-by-step) or manual splicing by menu selection. Conduct communication with the fusion splicer through a language unspecific keyboard with universal symbols and display the dialogue with the splicer on the device screen.

2.4.2 Conduit, Fittings And Enclosures

Ensure conduit, fittings, and enclosures are as specified in Section 26 20 00 INTERIOR DISTRIBUTION SYSTEM, and as shown.

2.4.3 Fan-Out Kits

For all loose-tube optical fibers, furnish and install fan-out kits using furcating tubes for connectorization. Incorporate strain relief for loose-tube optical fiber furcating tubes if the connectorization is not contained within a protective enclosure such as a patch panel. For tight-buffered optical fibers, furnish and install fan-out kits using furcating tubes and which incorporate strain relief, if the connectorization is not contained within a protective enclosure such as a patch panel. Furcating tubes required to incorporate strain relief also provide increased pullout protection. Tubes are comprised of an inner tube, surrounded by a layer of nonconductive strength members, then surrounded by an enclosing outer jacket layer. Color code fan-out kits to match the industry fiber color scheme. Length of furcating tube is 2436-inches minimum when installation is complete. Rate fan-out kits for the ambient conditions of the location as specified in paragraph ENVIRONMENTAL REQUIREMENTS. Provide terminations for each fiber, regardless whether fiber is active or spare.

2.5 CABLE CONSTRUCTION

2.5.1 Interior Cable

Loose buffer tube cable construction is such that the optical fibers are surrounded by a tube buffer, and contained in a channel or otherwise loosely packaged to provide clearance between the fibers and the inside of the container allowing for thermal expansions without constraining the fiber. Extrude the protective container from a material having a coefficient of friction sufficiently low to allow the fiber free movement.

Use fluorocopolymer (FCP) for the cable outer jacket, which complies with NFPA 70 for optical fiber nonconductive plenum (OFNP) applications. Do not exceed the manufacturers' recommended values for tensile strength, impact resistance, and crush resistance. Insulation and jacketing cable material cannot contain any polyvinyl chloride (PVC) compounds.

For tight buffer tube cable construction, use extrusion of plastic over each cladded fiber, with an outer jacket of FCP, which complies with NFPA 70

SECTION 27 21 10.00 40 Page 5 for optical fiber nonconductive riser (OFNR) requirements for riser cables and vertical shaft installations. Cover optical fibers in near contact with an extrusion tube and an intermediate soft buffer to allow for the thermal expansions and minor pressures. Do not exceed manufacturers' recommended values for tensile strength, impact resistance, and crush resistance. Insulation and jacketing cable material cannot contain any polyvinyl chloride (PVC) compounds.

2.5.2 Pigtail Cables

Use flexible fiber pigtail cables for connections to equipment having the same physical and operational characteristics as the parent cable. Ensure the cable jacket is FCP, which complies with NFPA 70 for OFNP applications. Maximum dB loss for pigtail cable is 3.5 dB/km at 850 nanometers, and 1.0 dB/km at 1300 nanometers, and .5 dB/Km at 1550 nanometers.

PART 3 EXECUTION

3.1 INSTALLATION

Install system components and appurtenances in accordance with the manufacturer's instructions and as shown. Provide interconnections, services, and adjustments required for a complete and operable data transmission system.

Where installation procedures, or any part thereof, are required to be in accordance with the manufacturer's recommendations of the material being installed, submit printed copies of these recommendations prior to installation. Installation of the item is not allowed to proceed until the recommendations are received and approved.

3.1.1 Interior Work

Install conduits, tubing and cable trays for interior FO cable as specified in Section 26 20 00 INTERIOR DISTRIBUTION SYSTEM and as shown. Ensure cable installation and applications meet the requirements of NFPA 70, Article 770. Properly support and secure cables not installed in conduits or wireways. If installed in plenums or other spaces used for environmental air, comply with NFPA 70 requirements for this type of installation.

3.1.2 Service Loops

Ensure each FO cable has service loops of not less than 9.8-feet in length at each end. House the service loops in a service loop enclosure.

3.1.3 Metallic Sheath Grounding

Ground the FO cable with metallic sheath that enter buildings at a point as close as practivable to the building point of entrance. Ensure FO cable with metallic sheath routed in the trench with a power cable has the metallic sheath grounded at the cable termination points.

3.1.4 Splices

3.1.4.1 General

No splices are permitted unless the length of cable being installed exceeds

SECTION 27 21 10.00 40 Page 6 the maximum standard cable length available from a manufacturer or unless FO pigtails are used to connect transmitters, receivers, or other system components for terminations to the fiber. Make splices using the method recommended by the cable manufacturer. Place splices in a splice enclosure and encapsulate with an epoxy, ultraviolet light cured splice encapsulant or otherwise protected against infiltration of moisture or contaminants.

Field test FO splices at the time of splicing. Ensure fusion splices have a nominal splice loss of 0.15 dB for multimode and for single mode cable fusion splices and a maximum fusion splice loss not more than 0.3 dB loss.

3.1.5 Enclosure Sizing and Cable

Size termination enclosures to accommodate the FO equipment to be installed. Sizing includes sufficient space for service loops to be provided and to accommodate a neat layout of equipment and the bend radii of fibers and cables terminated inside the enclosure.

3.1.6 Enclosure Penetrations

Install enclosure penetrations from the bottom. Seal penetrations with rubber silicone sealant to preclude the entry of water. Internally seal conduits rising from underground.
