Since the 1980s, the fiber optic splice closure has played a good role in the connection and divergence of optical communication lines. In particular, fiber optic communication has evolved to the point where light enters and retreats today, and fiber optic splice closures are widely used in the field of communications. Major communication operators purchase large quantities of fiber optic splice closures every year and invest in optical fiber communication projects. People have higher and higher requirements for the performance and product quality of the fiber optic splice closure. For example, the three major operators in China must carry out selection inspection and arrival inspection on the purchased fiber optic splice closures every year, and strictly control the quality of products to ensure the quality of communication.
The fiber optic splice closure appeared in the early application of the communication field, because the production of the cap type fiber optic splice closure is not complicated by the horizontal plastic mold, and the sealing performance is relatively easy to reach the standard. Therefore, the demand for a cap type fiber optic splice closure is higher than that of a horizontal type. However, the market now finds that horizontal demand is more than a hat. Because, from the perspective of installation and maintenance, the horizontal fiber optic splice closure is easy to install, maintain and expand. However, whether it is horizontal or cap-type fiber optic splice closures, the principle of product quality should be followed.
When purchasing the fiber optic splice closure, be sure to identify the use and objects of the fiber optic splice closure:
1. The structure of the optical cable used is a layer twist type, a center tube type or a skeleton type.
2. The environment used, that is, overhead, direct burial, pipeline or underwater.
3. The type of fiber, that is, single core or ribbon.
4. The network structure, that is, whether it is necessary to go offline, on-site branches, and so on.
