Greentel Fiber Closure

The cable splice box, also called fiber optic splice closure and barrel, is suitable for direct and branch connection of overhead cables, pipelines, and direct burial methods for various structural optical cables. The box body adopts imported reinforced plastics, which has high strength and corrosion resistance. The terminal is suitable for the connection in the terminal room of the structure optical cable, the structure is mature, the sealing is reliable, and the construction is convenient. With the increasing popularity of fiber optic cable networks, fiber optic splice closures that provide reliable connectors for fiber optic cables are becoming known and familiar to everyone. There are a wide variety of fiber optic splice closures available in the market. The new name of the fiber optic splice closure is the optical fiber splice box, which is a passive device that provides reliable guarantee for the continuity of the optical cable. It is divided into overhead, pipelin...

There are two types of fiber optic splice closures: Inline Closure and dome fiber closure. Ordinary fiber optic splice closures include pipe fiber optic cables. The horizontal type is more choice because it is more convenient to install and fix, but it will directly eroded to the fiber core after seepage (water vapor). ADSS and OPGW cable Generally, there are more cap types. Although the installation is complicated, the leakage prevention performance is good. Even if water vapor enters the fiber optic splice closure, there will be water at the bottom of the fiber optic splice closure, which generally has a low probability of affecting the fiber core. Especially in the southern regions where there is more rain and the air is humid, caps are preferred. The function of the fiber optic splice closure is to protect the optical fiber and optical fiber connector from vibration, stamping, bending, etc. and prevent moisture. Therefore, the fiber optic splice closure should hav...

About Inline Closure and Dome Fiber Closure: Closure is categorized as Inline Clsoure or Dome Fiber Closure by the direction of cable entries. Inline Closure has cable entries at both side and used for aerial or manhole (big enough to work inside). Dome Fiber Closure has cabe entries at one side and is used for hand hole (small and unable to work inside). In case of installation into hand hole, joint work is done at outside, then closure and the excess length of cables are stored into handhole. When storing closure, Inline closure needs larger space than Dome Fiber Closure because it has cable at both sides. Different between Dome Fiber Closure Description and Inline Closure Description The Inland type closure is also called Horizontal closure. The input and output are on the both sides. Inline closure is more suitable for backbone application. GreenTel provides various shapes closure of Inland type. All the closures we offered are with a great sealing perform...

Optical fiber connection is one of the most common and important links in optical cable engineering. The selection of optical fiber connection technology and connection box will affect the attenuation of optical fiber and the service life of optical cable. The optical cable that was put into operation early in the system will increase with the service life. The attenuation index of the optical fiber has changed abnormally. Most of the failures of the optical fiber appear on the fiber optic splice closure. The fiber optic splice closure is an important component that affects the attenuation performance of the optical fiber. The common failures of fiber optic splice closure in recent years, from the point of view of the failure of the fiber optic splice closure in the system, is nothing more than deformation and water seepage. The deformation of the fiber optic splice closure is mostly due to the poor operating environment, such as the annual run at the concentration of aci...
