Such deviations, caused by foreign underground structures or geological obstructions, whether planned in advance or uncovered during the cable installation should be recorded when: If the Document is identified or marked as a project number PN document, or as a standards proposal SP document, persons or parties reading or in any way interested in the Document are cautioned that: If requested by the excavator, the owner may assign an on site representative to provide facility locating services until normal facility marking has been completed.
The cable is available in sizes ranging from 10 mm to 29 mm ani. For this reason, fusion splicing is recommended for optical fiber connections in the OSP. They shall not produce significant galvanic corrosion effects, in wet or humid conditions, on other metals likely to be present in their use environment.
The enclosures house and organize groups of spliced tiq. Permanent wnsi 61 Table 14 – Uniform color code Color Red Yellow Blue Green Orange White Pink Facility Electric power lines and conduit Gas, oil, steam, and petroleum lines Water, irrigation, and slurry lines Sewer and drain lines Communication lines, including fiber optic cable Proposed excavation Temporary survey markings B. These devices, however, cannot be relied upon to determine the precise location of the underground facility.
Where access to both wireline and wireless services is required, the entrance facilities may require adjustment in size, quantity, and location.
The second type of closure is an in-line configuration. The OSP pathway includes the pathway through the point of entry into the building space. They accommodate cable, splice closures, racking systems, and electronic equipment e. Accommodations should be made for diverse APs. These pathways may consist of aerial, direct-buried, or underground, or a combination of these.
These cables are ideal for duct, tunnel or aerial installations.
Also, suitable corrosion resistant markers or cable tags showing appropriate facility owner operator information should be placed to facilitate visual identification of the fiber cable. Cables placed in tunnels shall have the appropriate sheath properties for the environment and shall be clearly marked.
eix In addition, a splice closure provides the necessary facilities for organizing and storing optical fiber and splices. Cross-connect jumper wire shall be wire of the same or higher transmission category as the cross-connect block. These manuals provide practices and methods by which many of the requirements of this Standard are implemented.
These cables shall be water-blocked and UV resistant cables.
The location of other utilities, such as electrical, water, gas, and sewer, shall fia considered in the selection of the telecommunications entrance facility tua. In these cases it may not be possible to cable the buildings in a star topology.
Where conduit extends between maintenance holes, a slope of 10 mm per meter. Handholes may be placed when the bends exceed either two degree bends or a total of degrees; or the section length of conduit requires a pull point for ease of cable installation.
Where such markings cannot be reasonably maintained due to circumstances beyond the excavator’s control, the facility owner should be contacted for assistance or re-marking. Details should also include the location of abrupt deviations taken from the cable’s normal planned route and placing depth. The connecting hardware includes terminal blocks that are used for transition from distribution cable to service wire, and cross-connect blocks that are used for cross-connection between feeder and distribution cables.
Where maintenance holes are installed in roadways, the lid cover shall support heavy vehicular traffic See figure 8. Markers are usually placed at right-of-way boundaries, utility or vehicular crossings, or at other locations dictated by local conditions. Optical fiber closures shall be capable of bonding and grounding cable shields and closures as required by applicable codes.
Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. All sizes of the closure and its intended encapsulant as system must not generate any exothermic condition that will damage the housing, cable insulation or connectors.
These include flood water or chemical exposure, sub-immersion in ice, and exposure to steam or fire. The owner should arrange with the excavator for a prompt new marking completion date or schedule, as may be specified by state law.
It is desirable that terminal blocks used for building entrance terminals be of the IDC type. This is compared to the breaking strength of an unspliced segment of the same wire. Documentation shall be accompanied by a legend specifying all symbols used. Purpose The purpose of this Standard is to enable the planning and installation of an outside plant structured cabling system infrastructure. The splice and closure shall be compatible with the wires. For joint facilities, the minimum depth of cover shall be determined either from table 11 above, or table 12, whichever depth is greater.
As ofthe standard is at revision D, replacing the revision C, revision B, the revision A, and the initial issue ofwhich are now obsolete.

Connector manufacturers shall provide suitable application tooling and any auxiliary products that may be required to ensure the maintenance and reliability of the connectors in all OSP environments. The facility location markings should be made above and in line with the facility, not placed at an angle over the facility, to allow for correct determination of the tolerance zone. Removable red markers shall be available for attachment to a pair termination to designate special circuits.
