Fiber Closure as a Transmission Medium Is Very Necessary for the Trunk Line. Fiber closure is not easy to branch because it transmits optical signals, so it is generally used for point-to-point connections. Fiber closures are produced in this situation. The experimental multipoint system for the fiber bus topology has been built, but the price is still too expensive. Due to the small power loss and attenuation of the optical fiber, there is a greater bandwidth potential. Therefore, the number of taps that an fiber closure can support is much greater than that of a twisted pair or coaxial cable. The current low-cost, reliable transmitter is a 0.85um wavelength LED that can support 100Mbps transmission rates and LANs in the range of 1.5 to 2KM. An LED detector PIN operating at a wavelength of 0.85um is also a low-cost receiver. Avalanche photodiodes have a higher signal gain than PIN, but they require a 20 to 50V supply, while the PIN detector requires only 5V. If you w...

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.

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.
