I was quite pleased to find this section made it into the final standard without much revision. In general, horizontal indoor cables shall be supported at intervals not exceeding 3 ft (91 cm). • Cable pulling shall be done by hand, except when tension meters, tension-controlled, or breakaway swivels are employed. Standard Recommended Procedure 005-011 | Issue 17 | June 2019 | Page 1 of 10 Duct Installation of Fiber Optic Cable 1. 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. for outdoor cables. two cables are placed in an open trench dug by a trencher or plowed directly into the soil. All work areas where bare fiber may exist shall be repeatedly and consistently cleared of all bare fiber pieces. We'll go through some of the more important sections now to bring you up to speed. • 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. Table 6: List of Facility Installation Standards ... underground cable television facilities, underground natural gas facilities, underground telephone facilities, underground fiber optic cable installations, legal survey requirements, required permits, etc. © 2020 Endeavor Business Media, LLC. One type is for aerial installations and the other for underground. Rule 2. Documentation. General section. Unless stated otherwise by the cable manufacturer, the maximum pulling tensions used for optical cables shall be 300 lbs. 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 … All fiber optic cable terminations should be marked on racks or boxes where the cables terminate. Underground Fiber Cable Installation: Cautions. • 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. depending upon the type of soil, surface loads, and applicable regulations. Generally, one or. Direct Burial Underground Fiber Optic Cable lets you bury communications and transmissions systems underground without requiring additional protection. Twisting Avoidance: use a break-away swivel, verify load rating is 600 lbs. 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. The length of optical fiber cable; Number and quality of optical fiber splices in the optical fiber channel; Number and quality of optical fiber jumpers (e.g., patch cord assemblies) Each set of IEEE optical fiber network applications equipment feature a standards-based loss budget for … • End-to-end loss testing on each individual link in the system, if transmitter-to-receiver loss is beyond acceptable limits. The entry of outside plant cables into a structure may require special fire safety considerations. Rule 3. With two primary safety hazards associated with optical fiber systems, the more commonly talked about hazard is retina damage; due to looking into the ends of live fibers. This is not especially difficult, but it does require time and effort. Limitations: Optical fiber cables must be handled in compliance with their stated design ratings. These sections outline proper installation of optical cable. JEA FIBER OPTIC CABLE STANDARDS JEA has standardized on two types of fiber optic cable designs. The first requirement is "all fiber-optic cables should be installed in accordance with their listings and manufacturers' instructions." More importantly, it requires a change of mind-set for workers that cut their teeth on power wiring. †«yI’KhSÃÇ«ûî'+ø²Nþ}½Ô¦½™ç³Íí¦Ý­—ÉÇ{¸ƒm×ÛÓ¤a0")rPá!Ã`BÙË5–UÄzaËü(zÞ©` ½…¶ß²HKUŸdŸQ>tGûm(Hö©Î×e‹‹‚°…O^'½òOI¢×. The cables' minimum bending radii shall not be violated. Notice that with power wiring we are seldom concerned with supports being overtightened. It is intended for personnel with prior experience in planning, engineering, or placement of underground cable. • (Optional) End-to-end losses of individual fiber links The following tests shall be performed on all fiber-optic cable installations: • Continuity testing upon delivery of optical cables to the site of installation, • End-to-end loss testing for each complete transmitter-to-receiver link. But with data cables (not only fiber), overtightening is a frequent source of cable damage you must avoid. Metropolitan Communications Group is an established leader in the underground construction and maintenance of communication infrastructures. Another section addresses the tightness of supports. Pull boxes shall be sized so that no cables in the box shall be tightly bent. • Fiber-optic work areas shall be clean, organized, well lit, and shall be equipped with a bottle or other suitable container for broken or stray fiber pieces. 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. The FOA and NECA (National Electrical Contractors Association) in 2001 cooperated to develop the first ANSI standard (American National Standard) covering the installation of fiber optic cable plants. 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. MCG has constructed fiber optic systems and traditional copper throughout the country. Hence the safety requirements of this section of the standard: • Live optical fiber ends (live fibers are those with signals being sent through them) shall not be inspected by technicians; fibers shall be dark (no signal being transmitted) when inspected. Cable jackets shall not be directly pulled unless designed for the purpose, or unless the run is very short and requires a minimal pulling force. My recommendation is to allow 30 mm at every outlet box, and at least 3 m at every pulling point. • Continuous cable pulls shall be used whenever possible, avoiding splice points. Exceptions shall be made to this requirement only for very short runs, which require a minimum pulling force. Always roll the cable off the spool instead of spinning it off the spool end. (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.) Ergon Energy Corporation Limited ABN 50 087 646 062 Ergon Energy Queensland Pty Ltd ABN 11 121 177 802. During the installation of fiber optic cable, it is highly recommended to use a pulling grip commonly placed with several feet of soil cover over the cable with the depth of cover. Because proposed installation would occur at a depth of more than one foot below ground, the project could impact existing underground utilities and service connections. Underground Fiber Optic Cable Installation The practice of handling fiber optic cables has become much more common in recent years. Loops of cable (commonly called service loops) shall be provided at all intermediate pulling points, such as in manholes and pull boxes. It defines performance requirements for components and cabling systems. II.1. Reflecting back on the past year, we thought it would be worthwhile to revisit the 10 most popular photo galleries of 2016. Specification for Installation of Underground Fibre. The requirements of this section are as follows: All optical test results shall be thoroughly and accurately documented, and copies of the test results saved in a permanent form (typically in both hard copy and on computer disk). II. The intent of the standard is to define "a minimum level of quality for fiber-optic cable installations.". Underground Utility Standards ASTM underground utilities standards include standard practices for installing and operating optical fiber systems and repair of sewer systems. From site surveys to solution design, to installation and certification of copper and fiber optic cable systems, BEI Connect creates the highest-quality cable infrastructures to support our clients’ needs. 1.1 Products and Applications Included This standard covers fiber optic … Cable ties shall not be cinched too tightly, and shall have the free tab cut off, to prevent overtightening in the future. After mentioning that manufacturer's instructions take pre-eminence, the following rules are given: • When pulling optical cables into conduits, cable trays, or raceways, the strength member(s) of the cable shall bear all or nearly all of the pulling force. Cables in raceways are considered to be adequately supported by the raceway. Although this seems obvious, one section details how cables must be supported: All optical cables shall be securely supported, and shall have the supports spaced closely enough that there will be no excessive force placed on the cable. Hence, fiber optic cable installation into a duct using a pulling method is suitable to apply within short distances.

This will put a twist in the … A working familiarity with underground cable requirements, practices, and work operations is Fiber optic cables should be specified with colored jackets per industry standards which identify the cables as fiber optic cables and indicate the type of fiber in the cable. Copies of the standard are available from the National Association of Electrical Contractors (NECA), and perhaps from some of the standards organizations themselves. a) Splicing shall be performed as per provided documentation and reference drawings. The payment of these reserved pipes and cores by a new operator will follow the Guidelines for fiber and duct sharing. Voice, data and fiber optic cabling. Underground fiber optic cable facilities installation could occur in public streets and railroad rights-of-way, which are areas commonly used for utility corridors. In addition, other types of testing may be required for certain types of installations. As of late 1998, a joint venture of the National Electrical Contractors Association (NECA) and the Fiber Optic Association approved and published ANSI/NEIS Standard 301. The pulling force shall be uniform and consistent; cables shall not be jerked. For most electrical installations, the only testing done is flipping on the light switch or pushing a Wiggy into the outlets. • When underground raceways containing optical cables enter a structure, the raceway shall be sealed to prevent the entry of gasses into the structure. These sturdy cables are built to resist moisture, heat, soil acidity and other environmental factors that could interfere with their performance. • When pulling fiber-optic cable through nonmetallic raceways (or nonmetallic 90 degrees elbows) with rope, maximum speed through a duct shall be about 3 ft (91 cm) per second. Yes, the NEC has covered optical cable for longer than that, but these requirements focus on fire safety and installation with electrical conductors; and not a whole lot more. 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. • When powered pulling equipment is used to install optical cable, tension monitoring equipment or breakaway swivels shall be used. When installing optical cable, what you don't know could really hurt you or damage your cable.

Here are some of the things that must be taken care of: You need to bury the cable below the frost line to prevent damage by background frost heaves; You need to keep the trench as straight as possible. Familiarizing yourselfwith Standard 301 is a smart step to avoid such problems.Up until a little over a year ago an installation standard for optical cable didn't exist. Fiber optic cables are designed to withstand all typical installation and environmental stresses expected in the specific application. and testing cabling networks that use fiber optic cables and related components to carry signals for communications, security, control and similar purposes. When optical cables are squeezed out of shape, unacceptable forces are placed on the fibers, which frequently result in microbends, microcracking, or even broken fibers. If mule tape is used, the top speed shall be 9 ft (274 cm) per second. (136 kG) for multi-fiber indoor cables, and 600 (273 kG) lbs. Few fiber systems have power enough to cause eye damage (cable TV systems being the exception), and most broken fiber ends will diffuse the light passing through them anyway. Underground utilities standards address safety and access rights, selection of the utility, and the continued maintenance of the utility once fiber has been installed. Again in 2016, conveying technical content through visual images in the form of photo galleries proved to be one of the largest website traffic generators among our readers. HUO(24) Underground filled fiber optic splice closure and organizer capable of accommodating a minimum of 24 fibers.

Presented in descending order, these galleries are ranked based on total website traffic over the last 12 months. 2) SPLICING. The second concern, however, is far more serious. The intent of this requirement is that the nonmetallic conduit or elbows will not be cut or grooved by the pulling process. Here are the 5 basic rules to follow when installing any fiber cable. Familiarizing yourselfwith Standard 301 is a smart step to avoid such problems. Familiarizing yourselfwith Standard 301 is a smart step to avoid such problems.Up until a little over a year ago an installation standard for optical cable didn't exist. All bare fiber pieces shall be disposed of so that they cannot escape and cause a hazard. (For example, bare fibers should be sealed in some type of bottle or container before being dumped into a wastebasket.). The 10 Most Popular Photo Galleries of 2015, The 10 Most Popular Photo Galleries of 2014. In real life, however, this is a rare situation. Fiber optic cable pulling sheaves should also be used at both the pulling end and pay-off end of the installation in order to maintain the proper bending radius of the fiber optic cable as the cable enters and exits the hand-hole, man-hole, etc. Electrical Product Listing: To Be or Not to Be? The fiber cable warning labels must be buried directly above the cable All such trace copies shall be clearly marked as to the date taken, and details of the cable and fiber runs. Nonetheless, this is a legitimate concern. But for data, every run of cable must be separately tested and the results permanently documented. Optical cable is usually placed in a 25 to 40 mm inside diameter (ID) sub-duct which is placed into an existing larger diameter communications conduit. (1.3 cm) in diameter. This is the hazard posed by broken pieces of fiber. They shall also check their clothing, and pat themselves with clean tape to remove any stray pieces of bare fiber. Cables directly buried require no additional support. Swivels shall be used when pulling optical cables intoconduits. Long runs shall be tested with an optical time domain reflectometer, and permanent copies shall be made of all OTDR traces. • 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. 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. Fiber optics transmit data much more quickly – and in much greater volume – than CAT 5e or CAT 6 copper cabling. When installing optical cable, what you don't know could really hurt you or damage your cable. Optical cables shall not be pulled into place by applying tension directly to the fibers (pulling the fibers). Where possible, rounded or padded supports shall be used. If you're company installs optical cable, you'll need to become very familiar with the guidelines outlined in this standard. Extensively revised to cover the latest technologies and equipment, this portable tool shows you how to … The standard also lists general rules to be followed when pulling cables into place. This standard covers an all-dielectric fiber optic (wrap) cable designed to be helically wrapped around a conductor or other messenger on overhead power facilities. Under this condition, the fiber cable needs to be stored in coil form at each manhole/handhole available at every 200 to 300 meters.
