Increasing the number of optical fiber cores is the most efficient way to increase the transmission capacity of fiber optic cable lines. However, it will also bring a series of problems such as fiber diameter is too thick, fiber can not be identified, repair difficulties and so on. This article will

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

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,

With the development of data center construction towards overall availability, there is a growing demand for cabinet management in server rooms. Users should consider the following factors when purchasing cabinets:1, load-bearing guarantee: with the increased density of products placed in the cabine

Among the rackmount server sizes, the common ones are 1U server, 2U server, 4U server, the size of these servers are: 1U=4.445cm, 2U=4.445*2=8.89cm, 4U=4.445*4=17.78cm. In practice, 1U or 2U servers are most often used. Because the service provider is based on the space occupied by the server to cal

Since the fourth quarter of 2022, the fiber optic cable industry is facing a lack of orders, low start rate situation, mainly due to China Mobile, China Telecom did not start the ordinary fiber optic cable, outdoor fiber optic cable collection bidding project, to the fiber optic cable manufacturers

Power communication fiber optic cables are very prone to failures in data transmission, which are generally manifested as reduced transmission rate, poor transmission quality, transmission interruption and so on. In the face of such a situation, reasonable means should be taken to deal with the fail

1、From the design point of view Comprehensive wiring has a point requirement if you have noticed, that is, the information point requires data, voice points can be interchanged when necessary
