Mobile communication base station is a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication exchange center in a certain radio coverage area. The construction of mobile communication base stations is an important part of the investment of mobile communication operators, and […]

How to use limited underground pipeline resources to lay new optical cables is one of the backbone network construction problems faced by network operators and contractors today. Because the pipe hole resources of underground communication pipelines are the communication basic resources that are in short supply for operators, except for newly built roads and development

Optical cable lines lightning protection and strong current protection are achieved by avoiding, guiding or discharging them underground to prevent lightning and strong current from causing damage to the optical cable lines themselves, communication equipment and personnel. Since the lightning protection and strong current protection measures for optical cable lines are often unified, they are

Although about 60% of the quality problems of home broadband services occur in the home network (see the article “Analysis Of Major Quality Problems And Causes Of Home Broadband Networks?”), all home broadband service quality problems are caused by the operators‘ network quality in the eyes of users, and users have thus formed an inherent

In FTTH and other broadband fiber optic access engineering design, it is necessary to calculate the attenuation of the ODN fiber optic link according to the corresponding wavelength of the application system, on the one hand, to verify whether it meets the requirements of the system’s optical power budget index, on the other hand, as

In recent years, G654E fiber has been increasingly used in new trunk cable lines. For a long time, G652D fiber has been the main fiber in trunk lines, and G655 fiber has only been partially used in cable lines built around 2003. One of the main reasons for using G654E fiber in current trunk lines

The start of the development of plastic optical fiber for communication (POF for short) is almost the same as that of glass optical fiber, both of which started in the 1960s. When it comes to the classification of optical fiber for communication, it is relatively easy to think of: multi-mode fiber, single-mode fiber, G.652, G.654,

ODN (Optical Distribution Network) from the service convergence point to the user is generally divided into backbone, wiring, access, fiber to the home multiple segments. The access section of traditional ODN cable construction involves a large number of fiber core splicing. In the user installation, the home section of the FTTH drop cable ends also
