Fiber Optic Cable

Field Connector In FTTH installations the optical drop cable will differ in length for every house, traditional fixed length patch cords will not always be suitable. The K&M field connector removes this problem as it can be fit- ted with no epoxy or power requirements in less than two minutes. Features: • No epoxy, no polishing • Well suited for FTTX • Less than two minutes assembly time • Outstanding optical performance Performance: Insertion Loss Typical ≤0.30dB Max ≤0.50dB Return Loss ≥40dB Material UL-V0 Mechanical performance Tensile 30N ΔIL<0.3dB Durability 10 times ΔIL<0.3dB Operating temperature -40°C ~ +70°C -40°C ~ +70°C Environment Storage temperature   Operating humidity -40°C ~ +80°C   ≤85%(+30°C) Name Code Comment Field Connector 023004820 Only fit to drop ca- ble Jacket stripper 051000030 Special tool Fibre stripper 051000000 Special tool Clean tool 051000010 Special tool Field connector assembly tool 051000020 Special tool Cutter - General tool End face inspector - General tool Problem Fiber Optic Connectors that require no epoxy and no polishing--often referred to as "quick-connect" connectors--have grown in popularity and are now widely used. Because a quick-connect connector is preloaded with a fiber stub that has been bonded and polished at the factory, it is sensitive to the quality of the cleave made to the fiber to be terminated. If proper installation procedures--particularly cleaving procedures--are not followed, these connectors may fail and be perceived as unreliable. Solution Take care when cleaving the bare fiber, and check the cleave before terminating the fiber. Procedure 1) Prepare the Fiber Optic Cable for termination as you normally would, by stripping away the outer jacket, buffer, and cladding and cutting away excess aramid yarn. 2) Using a fiber cleaver (usually included in the toolkits sold for these connectors), score the fiber with a single, light touch. Do not press the cleaver more than once, because doing so may make additional scores on the fiber and eventually cause it to break. 3) Break the fiber by bending it together with the tongue of the cleaver. 4) Examine the fiber with a microscope designed to inspect fiber cleaves. Ensure that the cleave is square and that there are no chips in the fiber. (Some manufacturers` toolkits include such microscopes. They have side ports in which you insert the cleaved fibers.) 5) Using the measuring card that is included with the manufacturer`s toolkit, or using the scale on the cleaver, measure the bare fiber to ensure it is the proper length. If the bare fiber is too short, it will not reach the fiber inside the connector, and the connector will not work. 6) Clean the fiber with alcohol wipes that have at least 90% isopropyl alcohol content and lint-free material. 7) Carefully insert the bare fiber into the connector until it meets the preloaded fiber stub. Using the manufacturer`s crimping tool, crimp the connector onto the buffer. Test connectors periodically during the installation, rather than testing them all after the job is completed. Periodic testing eliminates the possibility of repeating the same errors throughout the installation. Let’s check below Sample of installing SC/APC Fast Connector Ⅱ Disassembly 1.

For the lightning protection of the fiber optic splice closure in the optical cable line, it can be targeted to the local weather and terrain and other natural conditions. Through the analysis of the fiber optic splice closure in these years, it is found that the following problems should be paid attention to in the construction and maintenance of the fiber optic splice closure. 1. for the aerial fiber optic splice closure 1.1 Fiber optic splice closure usually has reinforced core can be connected or disconnected structure, regardless of the electrical connection is disconnected mode, the metal plate connection structure to superior to a bolt connection, and bolt is horizontal open hole is better than vertical slotted structure, which is selection of Fiber Optic Termination Box should pay attention to the problem. 1.2 Aerial fiber optic splice closure of metal parts, should it can be to every 2 km of grounding, grounding metal parts directly to ground or through proper surge protection grounding, such steel strand has protective effect of overhead ground wire. 2. For buried fiber optic splice closure 2.1 For the telecommunication bureau grounding of the Fiber Optic Cable, the metal parts of the cable in the fiber optic splice closure should be connected ,the strengthen core, moisture proof layer and armored layer connectivity preserving state. At the ends of the bureau (station) in the armoring layer, reinforced core should be grounded, moisture-proof layer through arrester grounding. 2.2 For without the copper wire Fiber Optic Pigtail, in accordance with the provisions of the YDJ14-91, in the fiber optic cable moisture proof layer, armored layer and strengthen core should be disconnection and are not grounded, to the ground is insulated, which can avoid the accumulation of induced lightning current in the optical cable. Practice has proved this method is simple and effective, as is usually the case, the metal component in the fiber cable of insulation value is higher, the lightning current is not easy to into the fiber cable, so as not to fiber optic splice closure damage.
