Fiber optic splice closure is a housing that contains and protects individual joints in any fiber system, rather than fiber splice (splice, lap and mechanical splice), which is covered in a separate blog. In view of the fragility of the fiber and the potential to upgrade the cable, high-quality closure is critical to the success of the installation. But what is off when you choose one when you should look for something?
Simply put, the fiber optic splice closure closes to connect a cable to a different length of the same type of cable. This is sometimes referred to as online blocking or tracking joints. The additional function is provided by a branch (or branch) connector that divides the cable into two ongoing sections. Main cable and side or auxiliary cable. There is also the end of the route closed, where the cable is broken down into separate components for the customer or telephone connection.
The earliest fiber optic splice closure was closed by their bronze cousins' direct descendants. The simplest structure (but not the use of!) Is surrounded by heat shrinkable products, usually just on-line closed, but sometimes branched joints. Although they can be waterproof, they have other benefits (except for low cost) and often require skilled interfaces to apply them.
Pipeline distribution closures have become common with the widespread use of blown fibers and cable systems that use multiple microbands. As the name suggests, these can create an online micro-track connector, or more often, to branch the miniature products to different destinations. Instead of the fiber splits that occur in the enclosure, the individual miniature products are connected together by a specially designed push-in connector specifically designed for waterproofing. This allows the closure to have a simple design without the need for expensive seals and easy assembly in the field.
Some fiber optic splice closure is closed and can be safely closed and forgotten. However, most of the need to re-enter to add or remove customers, upgrade the fiber or as part of the bug fix. This has led to advances in the use of cold seals for rubber seals, gaskets and gel compounds. Close requires a safe location. This means that it is safely placed in the basement, firmly connected to the air cable bracket, or installed in the customer building aesthetic considerations.
