The following describes FTTH access technical standards and deployment solutions, including how FTTH is connected to your network. As copper prices keep rising and the cost of optical cables keep decreasing, fiber-to-household (FTTH) services that provide bandwidth much higher than metal wire access are becoming the focus of ISP (broadband operator) promotion this year, in the near future, high-speed broadband will no longer be a dream for ordinary co

There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber.

With the gradual application of smart optical network ASON, the transmission network will gradually increase the number of intelligent network elements. As operators have invested heavily in the traditional SDH network, in order to protect the original investment and realize the smooth evolution of the traditional optical transmission network to ASON, the intelligent network and traditional devices will coe

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the

Cable construction is roughly divided into the following steps: Preparation → route engineering → Cable laying → cable connection → engineering acceptance. 1. Preparatory work (1). Check the design materials, raw materials, construction tools and equipment are complete. (2). To establish a high-quality construction team. This is important because optical fiber construction is more stringent than cable construction requirements, any construction of

The demand for bandwidth is increasing with the rapid development of network applications. This year's six-class cabling system, with its 250MHz bandwidth, has met most commercial applications today. However, with the continuous progress of technology, 250MHz bandwidth can not fully meet people's needs is only a matter of time. Therefore, in the next few years the development trend of cabling system on the seven types of cabling and optical cable is t

EPON technology is also one of the most important technologies in the access industry. through the rational use of EPON technology, it can make the design of the optical access network solution more reasonable and meet more user needs, we believe that with the development of the access industry, more new technologies will emerge. Overview Currently, the optical access network solution faces a series of tech

future application expansion. Today's Structured Cabling Design is gradually accepted by people. It is well adapted to the modular design ideas of data centers in the future, increasing manageability, reliability, and testability. However, it also brings about a relatively high initial construction cost and the additional loss caused by more connections in the cabling system. When designing and constructing a structured Optical Cable cabling system,

Spectral Analysis of Optical Signal-to-Noise Ratio of optical fiber networks The spectral analyzer (OSA) was originally used to measure the power spectrum of optical signals. After the introduction of wavelength division multiplexing (WDM), spectral analyzers were popularized because the standard power meter could not distinguish multiple wavelengths (

Based on years of experience in design and construction, the author summarizes a set of practical detection methods and shares them with colleagues. Check and install After the optical cable is connected and the connector is installed, the continuity check of the optical fiber must be carried out, and all the optical fiber cables must be tested. Therefore, the pe

The first application of ultra-low loss optical fiber in China Recently, China Telecom Jiangsu Corporation and Corning optical communication have successfully completed the laying and testing of ultra-low-loss optical fiber cables in Jiangsu Telecom's Provincial Trunk Lines. The test results show that the super-low-loss opti
