underground fiber optic cable installation standards
Reflecting back on the past year, we thought it would be worthwhile to revisit the 10 most popular photo galleries of 2016. ⢠If there is a risk of fibers being inspected live; especially when the system light source is a laser, all technicians working on the system shall wear protective glasses, which have infrared filtering. ⢠End-to-end loss testing on each individual link in the system, if transmitter-to-receiver loss is beyond acceptable limits. ⢠No food, drink, or smoking shall be allowed in areas where fiber-optic cables are spliced or terminated, or in any area where bare fibers are being handled. In general, horizontal indoor cables shall be supported at intervals not exceeding 3 ft (91 cm). II.1. Ergon Energy Corporation Limited ABN 50 087 646 062 Ergon Energy Queensland Pty Ltd ABN 11 121 177 802. The section reads: All straps or supports placed on fiber-optic cables shall be tight enough to hold the cable securely, but shall not be tight enough to substantially deform the shape of the cable. It is intended for personnel with prior experience in planning, engineering, or placement of underground cable. These are essentially small glass needles, and can be quite dangerous: Painful when stuck in the skin as a splinter, they are potentially life-threatening if ingested. The entry of outside plant cables into a structure may require special fire safety considerations. All rights reserved. and testing cabling networks that use fiber optic cables and related components to carry signals for communications, security, control and similar purposes. It defines performance requirements for components and cabling systems. All work areas where bare fiber may exist shall be repeatedly and consistently cleared of all bare fiber pieces. MCG has constructed fiber optic systems and traditional copper throughout the country. More importantly, it requires a change of mind-set for workers that cut their teeth on power wiring. But for data, every run of cable must be separately tested and the results permanently documented. Presented in descending order, these galleries are ranked based on total website traffic over the last 12 months. Underground fiber cable installations need to be carried out very carefully. Fiber Optic installation conductor shall install at least two (2) pipes with a minimum of twelve (12) cores on access network and 4 ducts on backbone network in order to facilitate fiber and duct sharing. Swivels shall be used when pulling optical cables intoconduits. Care shall be taken in verifying that the fibers are not live, since the light used in the majority of optical systems is not visible to the human eye. In the future, I'd like to see the standard contain specific requirements for the amounts of free cable that must be accessible at outlet points. a) Splicing shall be performed as per provided documentation and reference drawings. Hence, fiber optic cable installation into a duct using a pulling method is suitable to apply within short distances. We'll go through some of the more important sections now to bring you up to speed. (I was involved with the production of this standard, and its final form was by no means certain until the standards committee took several votes.) Standard Recommended Procedure 005-011 | Issue 17 | June 2019 | Page 1 of 10 Duct Installation of Fiber Optic Cable 1. JEA has standardized on All Dielectric Self Support (ADSS) fiber cables for aerial installations and Cable-in-Conduit type for underground applications. ⢠All technicians working on bare fiber shall thoroughly wash their hands immediately when leaving the work area. During the installation of fiber optic cable, it is highly recommended to use a pulling grip b) Standard optical cable color codes and fiber types shall be observed when fusion splicing two fiber optic cables together unless otherwise directed by the Ameren Representative. Rule 2. Familiarizing yourselfwith Standard 301 is a smart step to avoid such problems. The Contractor shall be responsible for: placement of cable, installation and attachment of cable to support devices within the utility tunnel system, underground structures, and pole lines, the placement of conduit, the installation of pull-boxes, the furnishings of fiber optic splice closures, and installation of termination hardware, and other as specified by UNM IT. Safety precautions. Minimum Bend Radius (MBR): maintain at all times. ⢠When pulls are accomplished in two or more stages, and spare cable must be unreeled, it shall be configured in large figure-eights on a safe, flat surface, such as the ground or a clean floor. The intent of this requirement is that the nonmetallic conduit or elbows will not be cut or grooved by the pulling process. © 2020 Endeavor Business Media, LLC. Generally, one or. HUO(24) Underground filled fiber optic splice closure and organizer capable of accommodating a minimum of 24 fibers. A fully updated fiber optic cable installation guide. Supports may be placed up to 5 ft (1.52 m) apart for armored cables, or cables over 1/2 in. Rule 1. ⢠Continuous cable pulls shall be used whenever possible, avoiding splice points. Electrical Product Listing: To Be or Not to Be? ⢠Boxes used with optical cables shall be designed for the purpose, and shall be equipped with cable supports. All such trace copies shall be clearly marked as to the date taken, and details of the cable and fiber runs. This will put a twist in the … Lashing Fiber Optic Cable To A Messenger Cable The installation process of a lashed aerial fiber optic cable will generally require one or more bucket trucks to allow workers to reach the location of the lashing, guide cables around poles and through trees or … The cables' minimum bending radii shall not be violated. Safety Precautions 1.1 Confined Space Precaution 1.2 Lead Exposure Warning 1.3 Cable Handling Precautions Corning Optical Communications cable specification sheets are available which list the maximum tensile load for This practice covers the basic guidelines for installation of fiber-optic cable in underground plant. ⢠Technicians making fiber terminations or splices or working with bare fiber shall be supplied with double-sided tape, or some other effective means, for picking up broken or stray pieces of fiber.
