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

After recent years of development, the home broadband market space has been saturated. By the end of 2020, China’s home broadband user penetration rate has reached 96%. The competition among operators in the home broadband market has also shifted from the competition for the number of new users to the competition for the quality of

POTDR is a polarization optical time domain reflectometer. When an optical fiber is deformed, the polarization state of the light signal changes from the deformed position. The principle technology of POTDR is based on the polarization properties of light and the scattering phenomenon. Light is composed of electromagnetic waves, which can vibrate in a specific
