What is the final ideal networking method among pon's networking methods?

Among PON's networking methods, "fiber to the home" is the ultimate ideal networking method; fiber to the home, also known as FTTH, is a transmission method of optical fiber communication. It is to install optical network units in residential buildings. At home users or enterprise users, it is the optical access network application type closest to users in the optical access series except FTTD.

Among pon's networking methods, "fiber to the home" is the ultimate ideal networking method

Fibre (Fiber) To The Home (FTTH) is a transmission method of optical fiber communication. Specifically, FTTH refers to installing optical network units (ONUs) at home users or enterprise users. It is the optical access network application type closest to users in the optical access series except FTTD (fiber to the desktop). The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the network's transparency in data formats, rates, wavelengths and protocols, relaxes requirements on environmental conditions and power supply, and simplifies maintenance and installation. PON technology has become a hot topic for global broadband operators and is considered to be one of the best technical solutions for realizing FTTH.

Brief introduction

FTTH (Fiber To The Home) - fiber to the home is the most comprehensive service so far , the best mode for high-bandwidth access requirements.

There are two main paths for the development of FTTH - active optical network and passive optical network.

Active optical network has the characteristics of long transmission distance, but the equipment is highly specialized and is not suitable for areas with dense users. Moreover, the port price is relatively high. In addition, the active characteristics also make the equipment installation greatly affected. limitations and are susceptible to electromagnetic interference in the surrounding environment, which increases network failure points and leads to higher maintenance costs.

Because the passive optical network is a pure media network, it has the natural ability to resist the influence of electromagnetic interference, reducing the failure points of the access network, resulting in higher system reliability and lower maintenance costs. At the same time, the FTTH in the passive optical network mode has good transparency and can support the application of multiple standards, making it more suitable for large-scale development of users. Passive optical networks have gradually become the mainstream development direction of FTTH.

The physical layer of FTTH uses optical fiber. The use of optical network provides a good basic guarantee for high-bandwidth business transmission capabilities. But the physical layer alone is not enough. What is more important to realize the transmission of information is the second layer control. Therefore, the development of FTTH has experienced a revolution on the second layer of the network - the development process from ATM to Ethernet, corresponding to the two series of APON and E/GPON.

Main Business

FTTH is a full-service integrated access solution. Although the main driving force of FTTH is future broadband video services, FTTH must be able to support various existing narrowband and broadband services, as well as new services that may appear in the future. The FTTH system must be able to provide comprehensive access so that users can enjoy multiple services at the same time. The main services that FTTH should support include:

Video: HDTV, using MPEG-2 standard compression, the pixels of the original image are from 1080×1920 to 4320×7680, using Dolby Digital 5.1 channel decoder system Multi-channel high-fidelity sound; standard DTV, using MPEG-2 standard compression, the pixels of the original image are around 640×720, ordinary mono or stereo; various still images using MPEG-1 and MPEG-4 and other compression technologies business and low-resolution surveillance image business.

Data: Data services with various code rates, ranging from a few Kbps to tens of megabytes.

Voice: including traditional POTS phone and digital phone services, multi-channel high-fidelity sound.

Multimedia: Various mixed data, voice, and image services of different qualities.
