Aerial fiber optic cable and intra-office fiber optic cable and splice installation regulations Dwdm fiber optic

Fiber optic Splice Closures
Aerial fiber optic cable 1. The sag of the aerial optical cable should be determined very carefully, and it should be considered that the elongation rate generated during the installation of the optical cable and when it is subjected to the maximum load after installation should be less than 0.2%. In the project, the sag of the aerial optical cable should be calculated according to the structure of the optical cable and the hanging method, and the elongation of the optical cable should be calculated, so that the determined sag of the optical cable can ensure that the elongation of the optical cable does not exceed the specified value. 2. The laying of the aerial optical cable is pulled by pulleys, and no excessive bending is allowed during the laying process. 3. In the medium load area, the heavy load area and the overweight load area, the hanging overhead optical cable should be reserved on each pole, and the light load area should be reserved every 3~5 poles. A protective tube should also be installed where the optical cable passes through the cross suspension wire or the T-shaped suspension wire. A protective tube should also be installed where the optical cable is connected to a cross or T-shaped suspension. 4. The hanging overhead optical cable should be adjusted uniformly after laying. The hanging distance of the optical cable hook is 50 cm, and the allowable weaving difference should not be greater than ±3 cm. The hasp direction of the hook on the hanging wire should be the same, the hanging direction of the hook on the hanging wire should be the same, and the hook support plate is complete. 5. Installation method and requirements of the lead-up optical cable of the hanging overhead optical cable 6. The anti-strong electricity and lightning protection measures of the overhead optical cable shall comply with the design regulations. When the hanging overhead optical cable crosses the power line, the steel rubber wire should be insulated with a rubber tube or bamboo sheet. The contact part of the optical cable with the tree should be protected by a rubber tube or a serpentine tube. fibconet.com dwdm fiber optic dwdm fiber optic
Intra-office optical cable 1. Intra-office optical cable 1 The manhole in front of the office is led to the optical transceiver through the underground access room. Due to the complex routing, it is advisable to use color and manual deployment methods. When laying out, a special person should be set up on the upper and lower corridors and at each corner, and they should be towed according to the unified command. During the towing, keep the optical cable in a loose state. 2. The intra-office optical cable should be marked for easy identification. 3. The optical cable should choose a safe position in the incoming room, and take protective measures when it is in a position vulnerable to external damage. 4. Optical cables should be bound through cable trays and inflection points (front and rear). Binding parts of up and down walkways or climbing walls should be padded with rubber hoses to avoid lateral pressure on the optical cables. 5. The optical cable reserved on the side of the terminal according to the regulations can be left in the optical terminal room or the cable entry room. There are special optical cables reserved in French, which should be reserved according to the design requirements. fibconet.com dwdm fiber optic dwdm fiber optic
General provisions for splicing and installation of optical cables 1. The content of optical cable connection should include: optical fiber connection, copper wire, aluminum sheath, connection of strengthening core, measurement of joint loss, packaging of joint sleeve (box) and installation of makeup head protection. 2. The optical cable connection should meet the following requirements: 1) Before the optical cable is connected, the regulations on the end of the optical cable should be checked, and the optical fiber, copper wire and braided wire should be checked for permanent marking; 2) Check the optical fiber, copper wire and arrange the wire for permanent marking in accordance with the provisions of Article 2.2.4 to identify the optical cable end; 3) The optical cable connection should check the quality of the optical fibers and copper wires of the two sections of optical cables before they can be connected; 4) The optical cable connection must carefully implement the requirements of the operation process; 5) The environment for optical fiber connection must be clean and tidy, and it should be operated in an engineering vehicle or in a covered environment, and open-air operation is strictly prohibited; 6) The connection parts, tools and materials of the optical cable should be kept clean to ensure the connection quality and sealing effect; 7) It is strictly forbidden to remove the primary coating with a blade or prepare the end face with a flame method for optical fiber connection. dwdm fiber optic dwdm fiber optic
