What is an all-optical network?

May 07, 2021

At present, Guanlian Company mainly produces optical network devices, equipment and other optical communication products, and provides related solutions, including optical end equipment such as GPON, EPON, optical fiber transceivers, Ethernet switches, optical fiber connectors, optical fiber adapters, and optical fiber splitters, Optical fiber distribution box and other optical fiber equipment.

All-optical networks have always been the focus of attention in the weak current industry. Many weak current project managers have been exposed to related projects. So what is an all-optical network? How to build an all-optical network project? In this issue, let's take a closer look at this aspect.

What is an all-optical network?

The so-called all-optical network refers to the fact that the network transmission and exchange processes are all realized through optical fibers. The signals are only converted into electro-optical and photoelectric when they enter and exit the network, and the process signals transmitted and exchanged in the network always exist in the form of light, so they can Greatly improve network speed.

When it comes to this, we have to talk about the POL all-optical network.

POL (Passive Optical LAN), passive optical LAN, a new type of LAN networking based on PON technology, optimizes the basic wiring and network structure of the LAN, and the network structure is more flat and simple. It inherits the advantages of PON network such as large bandwidth, high reliability, flatness, easy deployment, and easy management.

The POL network uniformly carries broadband, voice, video, WiFi, CATV, and office services.

The POL scheme is widely used in scenarios such as hotels, campuses, enterprise parks, enterprise office buildings, power, and transportation.

In the face of a large number of business communications, traditional cable transmission is bound to be limited and higher bandwidth is required. POL's all-optical LAN based on PON network can solve:

Longer coverage distance; more business types; higher user bandwidth; more streamlined network structure.
Straightforwardly speaking, the signal transmission and exchange process of the network always exists in the form of optical fiber, and the network speed is greatly improved. Therefore, the network structure is simplified, multiple services are carried on one network, and the network is "weighted down".
