Fiber patch cord fs

  1. 1. Fiber Patch Cord Management GuideThe fiber jumper is likely to be the weakest part in the Copper cable and fiber opticnetwork infrastructure. In the management of both copper cable and fiber jumpers, we mustfollow the correct operating procedures in order to achieve the best performance and reliability .At all levels to implement the best practices can minimize related costs.Best practices of fiber patch cord management can be divided into four parts:PlanningPreparationWiringVerification • PlanningRead design guidelines carefully ,outfit fiber jumperEnsure that you have grasped the specification and design of fiber-optic cabling. The jumpermust match with the cable has been installed, because the different types of fiber optic jumpercan not be mixed.Efficient routingTo select the appropriate length of the jumper, we must first determine the best route betweenthe two connection points. Usually we can choose the shortest route through horizontal andvertical cable channel, and must not impede or hinder the other jumpers or connectorsinthe patch panel.Avoid the jumper pass through a gridlocked cable channel.Determine the vertical and horizontal dimensionsDetermine the fiber jumper optimal routing obtain the required length by sum of the horizontaland vertical distanceTry to reduce the relaxationWhen you select, install and cross-connect the fiber patch cable, should avoid excessive slackand make sure fiber cable have a neat appearance. Jumper too tight will increase the tension on
  2. 2. the connector, while over-relaxation jumper will bring trouble to fiber patch cable management,and more increasing the difficulty of the management of patch panels.Efficient managementEnsure that the appropriate length jumpers have been ready, fiber patch panels have beeninstalled the right kind of cable management accessories.In general, every two rack unit needs to use a horizontal jumper cable management. In thespecific operation, we need depend on fiber optic patch panels or light guide Interconnect Unit(LIU) types.At the part of fiber optic patch panel or LIU, you must make the fiber jumper symmetricextension along the both sides of the vertical cable management pipeline to avoid one sideoverload.Old and new cable maintenanceDo not mixed use different jumper cable with core diameter. Different fiber optic standardconnector have been color-coded to help users easily to avoid confusion.Diameter of the cable coreFiber jumper cable core diameter must be same with the main cable. When a 62.5μm jumperconnected with and 50μm trunk fiber optic cable, there will be a larger attenuationFiber optic safety precautions and responsibilityThe optical transmission of information with the laser may cause damage on the retina but cannot be cured. Do not look directly at the power cable, a microscope or other magnifying devicesmay not be connected to the power fiber optic. Be sure to wear appropriate eye protectionequipment, and ensure that unused ports have been covered. • PreparationIn order to reduce the interruption, try to do more preparation before the implementation ofmanagement activities.Research management recordsDetermine the location of the port need to connect or reconnect. To ensure that the technicianclearly understand the task information, including the tag information of the relevant port.Check the fiber jumperMust ensure that the type and quality of the jumper accuracy, clean, and in good condition.Should check the fiber jumpers, excluding physical damage, including: 1. Stress mark on the sheath due to the bending stress
  3. 3. 2. The fiber optic is pulled out from the connector 3. There are cracks or scratches found the end of the fiber in the connector through the fiber optic inspection microscopeIn the fiber optic connections, cleaning is essential and so must carefully Attorney thefollowing: 1. The connector end of the jumper 2. Connector end of the patch panel 3. Connector end of the network equipment • WiringDistribution frame work once begin, we must immediately complete each phase of the missionbased on best practices。Fiber Jumper operationKnot, burr, pinch, and poor connection are likely to substantially reduce the performance of fiberjumpers. To avoid such problems, should focus on the following factors:Bend RadiusThe required minimum bend radius of fiber optic jumper cable depend on core diameter. 1.6 mmand 3.0 mm cable core, the minimum no-load bending radius is 1.4 inches (3.5 cm), but theinstall PATCH Plus of MPO jumpers cable minimum bend radius is 10 times of the core diameter.Exceed the bending radius may lead to more signal attenuation, and adversely affect theperformance information channel。Tensile and StressIn the process of Wiring, do not use excessive force. Or may increase the stress on jumpersand connectors, resulting in performance degradation. If you have to pull, it indicates that theremust be some problem. Find and fix the problem, and then the next step.BandingBundled cable enables patch panels looks neat, but if the strapping too tight, it will increase theprobability of extrusion. Do not over-tighten the clamp, make each jumper free rotation isappropriate. Please use the specific products, consider select the product without tools forrepeated use, such as Velcro.Make Jumper through the cable channel
  4. 4. If the existing jumper the appropriate length can be used again. At this point, should completelyremove the jumper to make it through the cable channel, re-wiring. This is the only way toavoid jumper tangle, knot or deformation.The steps of removal and adding fiber jumper1 find the TR / FD or ER two regions existing circuit2 Remove the plug at the end of jumper3 Gently upward to lift the jumper, get up slowly until you can perceive to mobile4 jumper removed from the line set5 Locate the other end , and allocated under the plug6 Determine the location of the new circuit7 plug one end of the jumper into the fiber coupler8 make sure jumper routing in place9 In the region away from the switch or the computer port, find the location of the newconnection point10 plug the other end into the fiber optical coupler • VerificationThe last visual inspection, closed patch panelDue to an error could lead to costly disruption and rework, so wiring must be success one time.Spend more time on the connection to the final visual inspection is worth doing. After the patchpanel installed in the cabinet must take the cabinet firmly locked up. Ensure jumper relaxationpart not kinked, not griped by cabinet door .Update recordsThe final step is to update records according to the current configuration, and request relatedwork orders for completed changes.
  5. 5. End-to-end cabling connection of all types only as strong as their weakest link, so you need to be sure you manage patch cords properly. Patch panels that look like this compromise the performance and relilty of the network.planning-moves, adds or changes should be with a change request, which may be paper based or electronic
  6. 6. attempting to save time by not following proper cord routing will eventually lead ti mistakes and difficulty routing cords.the performance of the end-to-end channels determined by the lowest performing component. Make sure you know the specification and design of your cabling infrastructure, and ensure cords are matched to the canling
  7. 7. once you know you have the right cords, consider how they will be installed on the patch panel. Key factors are routing ,patch cord length and density. For efficient routing, find the best path between the ports to be connected. when working with optical fiber cords, pay attention to the core diameter
  8. 8. A large attenuation penalty will occur when using 62.5μm jumper connected with and 50μm cabling plant, and vice versa Single mode cords must be used with single mode cabling, also matching the mode field diameter of the installed cable
  9. 9. Inspect fiber cords for physical damage including stress marks from sharp bends on the sheath ,or damage to connectors
  10. 10. cleaner is vital in fiber optic connection, including lc. sc and mpo connection. Special care is needed with connector ends on patch cords. connector ends on park, and connector end on network equipment.Ensure unused optical fiber ports are covered. The laser used in optical fiber may cause damage to the retina. Never look into am energized fiber
  11. 11. Always maintain the correct tend radlus for copper and optical cords
  12. 12. Be careful not to use excessive force during the patching process. This can stress cords and connectors reducing performanceIf you need to use force when pulling a cord, something is wrong. and fix it before proceeding Correct bunlding of cords is also key to efficient cord management
  13. 13. Any unused cords should always be removed from the panel before new ones are added. Accurate labeling is essential ,labels should be visible and durable
