In outdoor installations, a common practice of 2.5 foot sag for 150 foot span is good for thermal expansion and contraction. 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 various cable types. CABLExpress is dedicated to delivering quality in every product we provide – and every interaction you have with us. www.cablexpress.com. There is also a chance that some human hands have touched it, or a particulate has scratched it. Accessibility considerations are critical when mounting and/or installing cables. Record all required fiber optic facility details, including proper route drawings, fiber assignments, loss readings, OTDR traces, etc. This allows for the addition of new cables and later removal of them when they are no longer needed. Confirm with the design or Port Map document if trunking is to come from both sides of the cabinet (left and right) or just one side of the cabinet. Monitoring the supply reel during installation is necessary to prevent violation of minimum bend radius. Leave the protective thermal wrap … The number of 90 degree turns on a pull shall not exceed 6 for aerial cables and 4 for underground cable-in-conduit. Silicon Valley's fiber optic products distributor. Safety precaution – do not look into fiber without checking status. On runs from 40m to 100m, use proper lubricants and make sure they are compatible with the cable jacket. And always use a swivel pulling eye because pulling tension will cause twisting forces on the cable. Protect fibers and buffer tubes. Never twist the fiber cable. Confirm the document is up-to-date and reflects any possible last-minute changes that may have occurred under the floor or in overhead conveyances. Look for signs of stress on the cable jacket. The minimum air pressure in the duct should be 100 psi with 125 psi recommended. If you don’t already know someone here, we’re glad you found us and happy to get to know you! This will avoid safety problems such as fiber splinters and unintentional abuse. The pulling tape should have a rating for greater than maximum anticipated pulling tension. Implementation of these outlined fiber optic cabling installation best practices will ensure the best environment for proper functioning of your cables. Trunks are custom-built and cannot be returned. We are a division of CXtec, so you can order product directly from the account manager you’ve always dealt with at CXtec, CABLExpress, Atlantix, or TERACAI. This will put a twist in the cable for every turn on the spool! It’s from here that you’ll run the fiber optical lines into your house for phone, Internet and TV. The person may stop the cable pull from time to time to prepare and apply more lubricant. Leading cable manufacturers like Shenzhen OTS Cables Technology Co., Ltd.provide many types of state-of-the-art fiber optic cable that suit every customers' needs. Just call us at 800.913.9465 during business hours EST, or fill out the form on this page. Conduit Installations General Information: Try to design the conduit run with a few bends as possible. In general, fiber optic cable can be installed with many of the same techniques used with conventional copper cables. Cables should be tested after shipping. It’s true that fiber optic cable, based on optical technology to carry information between two points, have become increasingly important in fiber optic Always make allowances for power cable sag due to weather and current conditions. Care should be taken to use the correct insert size. Always make sure that access to other major components is not blocked. A quality assurance checklist with appropriate photos and sign-off should also be provided. You can eliminate 95% of the problems installers can encounter by simply creating this plan. Putting a twist in the cable can stress the fibers too. We need to install a fibre cable from your street to your property and we want your fibre install to have as little impact on your property as possible. The minimum crew should have one person monitoring the pulling equipment, one monitoring the supply reel, and one coordinating all involved in the installation. Allow for thermal expansion and contraction. During cable placement, it is really crucial that the cable not be bent to a smaller radius. Never exceed the cable bend radius. Be aware that solar heating due to sunlight exposure can increase the cable temperature well above the ambient temperature. The proper personnel should be contacted so that they are on the site when work is performed near high-voltage lines. Exceeding this limit can result in fiber breakage, excess attenuation, and, in loose tube cables, fibers sliding from cables. The tip of the fiber connector, where the fiber optic glass protrudes, is the most common area for damage to occur. Use the figure 8 technique. A cable shoot/pulley larger than the specified bend radius is recommended to minimize the cable bend at the first and last pulley locations or at any location with a change in direction. Do not store cable within the closure or pedestal unless there is enough room to accommodate the minimum specified cable bend radius. It is extremely important to take an accurate measurement when planning an order for a custom pre-terminated fiber optic cable assembly. Plan the Installation. Excessive stress can break and/or damage an assembly, causing it to improperly pass network traffic. You want to remove the contaminants prior to connecting. Pull, do not push cables. Condensation can also form in the bag the fiber is packaged in and find its way under the cap. Use plenum rated cable where it is mandated, etc., etc. Breakout lengths for your cables are the distance from the furcation point (where the individual cables separate from the consolidated, single sheathing) to the end of the connectors. Attach cables with plastic clamps having large surface areas. This loose end is pulling into the next section of conduit or duct. Never exceed the maximum pulling load rating. The two most common outdoor fiber optic cable installations in Ohio are pole-line aerial … On long runs, use proper lubricants and make sure they are compatible … There are only two per trunk, one per side. Bare glass fibers can cause splinters which are very difficult to find and remove. Grounding: Cable with metallic components shall follow the bonding and grounding requirements of the customer and local or national codes. These data logs should include both insertion loss measurement and OTDR measurements. Follow the blowing equipment suppliers blowing distance recommendations; 3000 to 6000 feet is a typical blowing length. The following fiber cable installation guidelines are recommended as best practices pre-, post-, and during installation of CABLExpress Skinny-Trunk® products in accordance with the TIA-942 Data Center Standard and our own experience! Create a detailed, written plan of installation. Fibers and buffer tubes do not have sufficient strength to resist breakage due to normal handling of copper cables. Proper training reduces expense through reduction of breakage and excess attenuation. In medium fiber-count cables (6 to 24 fibers), the connectors must be staggered when installed to reduce the diameter of the pulling grip. Use extreme caution when removing the pull eye. When a steel messenger wire is used for aerial installation, avoid zigzagging the messenger wire from one pole side to the other.
