How to choose an economical and practical cable drum packaging to drop cable? Especially in some countries with rainy weather like Ecuador and Venezuela, Professional FOC manufacturers recommend that you use the PVC inner drum to protect the FTTH Drop Cable. This drum is fixed to the reel by 4 sc...
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...
1. Electric Corrosion
For communication users and cable manufacturers, the problem of electrical corrosion of cables has always been a major problem. In the face of this problem, cable manufacturers are not clear about the principle of electrical corrosion of cables, nor have they clearly propose...
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...
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...
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...
2021,With the rapid increase of raw materials and freight, and the domestic production capacity is generally limited, how does gl guarantee the delivery of customers?
We all know that meeting customer expectations and delivery requirements must be the top priority of every manufacturing company i...
The implementation of the direct-buried optical cable project should be carried out according to the engineering design commission or the communication network planning plan. The construction mainly includes the route digging and filling of the optical cable trench, the plan design, and the setti...
The air blown cable greatly improves the utilization efficiency of the tube hole, so it has more market applications in the world. The micro-cable and micro-tube technology (JETnet) is the same as the traditional air-blown fiber optic cable technology in terms of laying principle, that is, "mothe...
Today, GL talks about how to improve the common measures of OPGW cable thermal stability:
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 protectio...
Adding ADSS cables to the 110kV line that has been in operation, the main problem is that in the original design of the tower, there is no consideration at all to allow the addition of any objects outside the design, and it will not leave enough space for the ADSS cable. The so-called space not o...
China top 3 air-blown micro fiber optic cable supplier, GL has more than 17 years experience, Today, we will introduce a specal fiber optic cable SFU (Smooth Fibre Unit ).
The Smooth Fibre Unit (SFU) consists of a bundle of low bend radius, no waterpeak G.657.A1 fibres, encapsuled by a dry acryla...
OPGW is more and more widely used, but its service life is also a concern of everyone. If you want a long service life of optical cables, you should pay attention to the following three technical points:
1. Loose Tube Size
The influence of the size of the loose tube on the lifetime of the OPGW ca...
As we all know that OPGW optical cable is built on the ground wire support of the power collection line tower. It is a composite optical fiber overhead ground wire that puts the optical fiber in the overhead ground wire to serve as a combination of lightning protection and communication functions...
Communication optical fiber cables are more commonly used in overhead, direct buried, pipelines, underwater, indoor and other adaptive laying optical cables. The laying conditions of each optical cable also determine the difference between the laying methods. GL probably summarized a few points:

Which optical fiber is used for transmission network construction?
There are three main types: G.652 conventional single-mode fiber, G.653 dispersion-shifted single-mode fiber and G.655 non-zero dispersion-shifted fiber.
G.652 single-mode fiber has a large dispersion in the C-band 1530~1565nm a...
Many customers ignore the voltage level parameter when purchasing ADSS optical cables. When ADSS optical cables were just put into use, my country was still in an undeveloped stage for the ultra-high voltage and ultra-high voltage fields, and the voltage levels commonly used in conventional power...
With the development of information transmission technology, Long-distance backbone networks and user networks based on OPGW optical cables are taking shape. Due to the special structure of OPGW optical cable, it is difficult to repair after damage, so in the process of loading, unloading, transp...
