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

Among those famous dome fiber closure manufacturers and suppliers, Green Telecom Tech Co.,Ltd can offer you customized DOME Fiber Closure and fiber optic termination , in this article, you will know the important factors that should considered for fiber optic termination. Insertion Loss of Fiber Optic System: Fiber optic cabling systems support various communications technologies like Gigabit Ethernet, local area networking (LAN) and CATV (community access television). No matter what types of networks it supports, the communication devices have a limitation for maximum channel insertion loss measured in units of decibels (dB). Optical fiber channel insertion loss usually occurs when an active transmitter is linked to an active receiver via terminated fiber optic cables, splicing points and fiber optic connectors. The quality of fiber optical links’ terminations has an impact on the channel insertion loss. Poor quality terminations often cause more loss than high-performa

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

Reasonably Designing the Insulation Grounding Structure of the Greentel DOME Fiber Closure : Insulating spacers conventionally used in fiber optic splice closures typically consist of two spacers. The upper washer is a grooved washer and the lower washer is a protruding washer. Since the fixing bolt is connected with the reinforcing core of the optical cable, the upper and lower insulating spacers can be combined to form the insulation between the metal component of the fiber optic splice closure and the cable reinforcing core . In the compressive strength test, a 15 kV DC voltage is applied between the fixing bolt and the metal part. Most of the materials used for insulating gaskets are high-molecular polymers. The dielectric strength of these materials is relatively high, typically 500 to 1000 megavolts/meter. Therefore, theoretically, only 0.1 mm of polymer-based insulation between two electrodes provides 15 kV protection. However, in fact, the insulating sheet used i

Greentelftth Fiber Closure should be easy to maintain and reuse. Due to the continuous development of urban construction, the number of cable television trunk lines is diverted, and some residential communities are under construction. The number of fiber-optic cores must have a certain amount of margin, so that it can be extended to new-building communities in the future. Therefore, the selection of fiber optic splice closures is necessary. The reconnection of the optical cable and the convenience of reconnection must be taken into consideration. Whether the fiber optic splice closure can be used again depends on the convenience of the opening and fixing of the fiber optic splice closure, the reusability of the rubber disk, the sealing strip and the fastener. For example, some seal strips are easily deformed or aged after use, and if used again It will make the sealing performance worse. The use of Greentel fiber optic splice closures: There are many types of greentel

Greentel Fiber Closure are an indispensable part of fiber optic cable communications. Its main function is to realize the connection of fiber optic cable, and at the same time, to ensure the grounding function of the fiber optic splice closure, the internal grounding device and the grounding portion of the optical cable must be electrically connected, and the metal component and grounding device of the fiber splice closure and the fiber cable reinforcement core must be guaranteed. They are insulated from each other to avoid adverse effects from the environment on the fiber optic splice closures. Fiber optic splice closures, like fiber optic cables, have their own quality and play a vital role in the transmission of communications. Since the environment in which fiber optic splice closures are used is basically outdoor, their use environment may be buried, overhead, or pipeline. In order to prevent the impact of lightning or other factors, it is required that the“vol

With the rapid development of cable TV, the use of optical fiber is more extensive. However, the laying of optical cables is often restricted by the environment such as traffic and spot layout, and the number of connections between optical cables is increasing. The failure of cable television transmission due to poor connection quality occurs from time to time. Most of these faults are caused by optical fibers. The selection and use of fiber optic splice closures are caused by improper use. Therefore, the reasonable selection and use of field fiber optic splice closure is an important part of improving the reliability of optical fiber transmission. Choosing the right fiber optic splice closure (that from greentelftth.com) first the capacity of the fiber tray should be considered .
