The design of the ADSS cable fully considers the actual situation of the power line, and is suitable for different levels of high-voltage transmission lines. For 10 kV and 35 kV power lines, polyethylene (PE) sheaths can be used; for 110 kV and 220 kV power lines, the distribution point of the op...
OPGW optical cable can be widely used in transmission networks of various voltage levels, and is inseparable from its high-quality signal transmission, anti-electromagnetic interference and other characteristics. Its use characteristics are:
①It has the advantages of small transmission signal los...
Many customers ignore the voltage level parameter when choosing ADSS optical cables, and ask why voltage level parameters are needed when inquiring about the price? Today, Hunan GL will reveal the answer to everyone:
In recent years, the requirements for the transmission distance have been greatl...
The professional drop cable manufacturer tells you: The drop cable can transmit up to 70 kilometers. However, in general, the construction party covers the optical fiber backbone to the door of the house, and then decodes it through the optical transceiver.
Drop cable: It is a bending-resist...
In current years, while the advanced information society has been expanding rapidly, the infrastructure for telecommunication has been building expeditiously with various methods such as direct burial and blowing. GL Technology continues to develop innovative and various type of optical fiber cab...
Some customers cannot make sure which type of multimode fiber they need to choose. Below are the details of different types for your reference.
There are different categories of graded-index multimode glass fiber cable, including OM1, OM2, OM3 and OM4 cables (OM stands for optical multi-mode).

What is the Fiber Drop Cable?
The fiber drop cable is the optical communication unit (optical fiber) in the center, two parallel non-metal reinforcement (FRP) or metal reinforcement members are placed on both sides, plus black or colored polyvinyl chloride (PVC) or low-smoke halogen-free material...
Due to factors such as ecological protection and economic reasons, it is not suitable to take measures such as poisoning and hunting to prevent rodents in optical cable lines, and it is also not suitable to adopt burial depth for prevention as directly buried optical cables. Therefore, the curren...
opgw cables are mainly used on lines with voltage levels of 500KV, 220KV, and 110KV. Affected by factors such as line power outages, safety, etc., they are mostly used in newly-built lines. Overhead ground wire composite optical cable (OPGW) should be reliably grounded at the entry portal to prev...
Anti-corrosion performance
In fact, if we can have a general understanding of the buried optical cable, then we can know what kind of capabilities it should have when we buy it, so before that, we should have a simple understanding. We all know very well that this optical cable is directly buried...
The development of the optical fiber cable industry has experienced decades of ups and downs and has achieved many remarkable achievements. The appearance of OPGW cable once again shows a major breakthrough in technological innovation, which is well received by customers. In the stage of rapid de...
Today, GL talks about the common measures of how to improve the thermal stability of OPGW cable:
1: Shunt line method
The price of OPGW cable is very high, and it is not economical to simply increase the cross-section to bear the short-circuit current. It is commonly used to set up a lightning pr...
When there are hybrid optical fibers in the photoelectric composite cable, the method of placing multi-mode optical fibers and single-mode optical fibers in different sub-cable groups can effectively distinguish and separate them for use. When a reliable photoelectric composite cable needs to str...
Composite or Hybrid Fiber Optic Cables that have a number of different components laid up within the bundle. These types of cables allow for multiple transmission paths by various components, whether they be metal conductors or fibre optics, and allow the user to have a single cable, therefore re...
In order to facilitate the laying and transportation of optical cables, when the optical cable leaves the factory, each axis can be rolled for 2-3 kilometers. When laying the optical cable for a long distance, it is necessary to connect the optical cables of different axes. When connecting, the t...
The technical parameters of OPGW and ADSS cables have corresponding electrical specifications. The mechanical parameters of OPGW cable and ADSS cable are similar, but the electrical performance is different.
1. Rated tensile strength-RTS
Also known as ultimate tensile strength or breaking strengt...
The first difference between GYXTW and GYTA is the number of cores. The maximum number of cores for GYTA can be 288 cores, while the maximum number of cores for GYXTW can only be 12 cores.
GYXTW optical cable is a central beam tube structure. Its characteristics: the loose tube material itself ha...
How to distinguish the advantages and disadvantages of ADSS optical cables?
1. Outer: Indoor fiber optic cables generally use polyvinyl or flame-retardant polyvinyl. The appearance should be smooth, bright, flexible, and easy to peel off. Inferior fiber optic cable has a poor surface finish and i...
As we all know, There are several parts that made up the fiber cable. Each part starting from the cladding, then the coating, strength member and lastly the outer jacket is covered at the top of each other to give protection and shielding especially the conductors and the fiber core. Above all of...
OPGW is a dual functioning cable performing the duties of a ground wire and also providing a patch for the transmission of voice, video or data signals . The fibers are protected from environmental conditions (lightning, short circuit, loading) to ensure reliability and longevity. The cable is de...
