1 PrefaceFiber optic cable line lightning and strong electricity, is through the avoidance, channeling or leakage into the ground and other means, in order to prevent lightning/strong electricity on the fiber optic cable line itself or communication equipment and people made damage. Since the lightn

1 IntroductionBefore 1980s, preserved wood poles (hereinafter referred to as "wood poles") were mostly used in communication lines. At that time, wooden poles were often called tarred poles because the preservation of wooden poles was treated with tar at post offices or long-distance service station

1 unequal score optical adaptation scenario analysisTraditional unequal score optical ODN introduction of fiber optic lines usually use a tree network structure, each splitter box is equivalent to the "leaves", generally assigned 2 cores (a master and a standby), the structure can be adapted to a va

The quality of the home network is mainly related to the performance of the home network devices, the connection between the devices, the quality of the wifi signal in the residence, and the use of the user.1 Performance of equipmentThe performance of the equipment that has a big impact on the wifi

The impact of broadband fiber access networks on the quality of home broadband services is often related to ODN fiber link interruptions, ONU weak light, GPON access to Gigabit subscribers, OLT uplink bandwidth limitations, and OLT reloading.1 ODN fiber link interruptionFrom the viewpoint of the cau

1. Increase the switchThe longest transmission distance of category 5 and category 6 network cable is 100 meters, if you want to increase the transmission distance, you can install relay equipment such as switches between the two twisted-pair cables, theoretically up to 4 switches can be installed.

1 IntroductionIn ODN, from the service aggregation point to the user is generally divided into backbone, distribution, introduction, home multiple segments. The construction of the introduction section of the traditional ODN cable involves a large number of fiber core splices. In the user installati

Due to different construction conditions and construction requirements, communication cables in different scenarios will take different laying methods, common laying methods include: direct burial, aerial, pipeline, underwater and bureau and so on.1 direct burial layingDirect burial,

What is the difference between indoor fiber optic cable, outdoor fiber optic cable, and indoor/outdoor fiber optic cable? Can outdoor fiber optic cables be used indoors?According to the usage scenario, there are Several categories of fiber optic cables, what is the difference between these categorie

Fiber optic cable lines and broadband access projects usually involve fiber optic cable single disk testing and fiber optic cable line testing, fiber optic cable line testing includes: relay section testing, user cable testing and so on. These test entries, some only need to use the test instrument
