Standards for Long-Term Storage Requirements of Optical Cable Reels
When storing cable drums for long periods, please take the following guidelines into consideration: ✓ Select a site for storage that is level and dry, preferably indoors with a concrete surface, with no risk of falling objects, chemical spills (oil, grease, etc. ) open. The following requirements and recommendations are applicable to both LAN copper and fibre cables. Please note: The Aginode warranty may be invalidated if the cables have not been properly stored or handled according to Aginode Belgium NV/ SA require-ments. Indoor LAN copper and OF cables are not. TRANSMISSION CONSTRUCTION STANDARD TCS-P-104. 0 SPECIFIC REQUIREMENTS FOR CABLE REEL HANDLING 4. 0 STORAGE SITES TCSP10402R0/YM Date of Approval: October 9, 2007 PAGE NO. During installation, all curvatures should be smooth. Do not attempt to lift drums of cable without inserting the fork lift tynes fully under both flanges as the tynes can damage the cable, making it unserviceable. These guidelines can apply. To assure undamaged cables, it is always good practice to handle fiber optic cables with care. Fiber Optic cable is sensitive to excessive pulling, bending and crushing forces.
