Passive Optical Network PON via Fiber Optica Media Converter

Uploaded2022/3/20 4:30:57     Hits    Source

With the development of communication technology, there are more and more new products appear. Passive Optical Network and Fiber Converter both are ways to transmit electric data. Then, there comes to a question. Which one is better? Will the PON system replace fiber media converter? So, this passage will divide into four parts. The first part will explain what is Passive Optical Network. The second part will explain what is Fiber Optical MediaConverter. The third part will compare the differences. The last part will discuss which one is better.

What is Passive Optical Network

Passive Optical Network can be abbreviated to PON. PON refers to does not contain any electronic devices and electronic power supply, and does not need valuable active electronic equipment. A passive optical network (PON) includes an optical line terminal installed at a central control station and a number of supporting optical network units installed in a user site. PON has two types, one is Ethernet Passive Optical Networks (EPON) and another is Gigabit-capable Passive Optical Networks (GPON). EPON has a larger market share at present, but it is mainly limited to Asia market. GPON is adopted by most communication operators, but whether it can catch up with EPON needs to be verified by the market. EPON has rich commercial experiences, but there are certain standardization and patents risk. EPON and GPON industry chains are very strong. Currently, EPON is more widely used, but GPON has better development prospects. PON, a pure medium network, not only can avoid electromagnetic interference and lightning effects of external equipment, but also reduce the failure rate of lines and external equipment, improve system reliability, and reduce maintenance costs.

What is Fiber Media Converter

Fiber optical media converter receives electric signal, and then converts electric signal into optical signal, or converts optical signal into electric signal. Actually, it just likes a container which allows optical signal and electric signal to convert internally. Without it, people would not be able to log on to the website and go online. As we all know, people use electronic equipment to achieve electronic communication in the past. However, there is a great limitation on converting electric signal that it does not work on long-distance communication. The appearance of fiber converter has greatly remedied this deficiency. Fiber optical media converter has six types which are the single fiber converter, the dual fiber converter and the single mode fiber converter and the multi-mode fiber converter and the managed fiber converter and the unmanaged fiber converter. The fiber converter has many features, such as rapid transmission, widely temperature resistance range, low cost, easily maintain and so on. It can be said that the emergence of fiber converter has made people’s communication a milestone.

Comparision between PON and Fiber media converter

As two different technology, the PON and Fiber media converter all have their unique advantages.

1.    Fiber optical media converter access has been widely used in traditional engineering projects, which can provide high network transmission bandwidth. All users share the bandwidth in PON system, the single user have small bandwidth when all users work together.

2.    PON has high utilization rate of optical fiber resources. In PON system, many users share one fiber system. In the fiber media converter, it is point to point application, every user need its fiber resource. So the fiber media converter need more fiber cable based on same users quantity.

3.    The PON network structure is complex, the fiber optical media converter network structure is simple. It is very easy for construction of fiber media converter.

4.    The capacity expansion of PON is high, it is easy to add users after the PON network construction. The expansion performance of fiber media converter is low, which need to do construction again if you need to add users.

5.    PON maitainance is complicated, PON system has strong management, which need more time to do configuration. Fiber media converter also have management, but it is not complicated as PON system, it is easy to manage and install.


Do we need PON or fiber media converter?

Passive Optical Network and Fiber Converter both have its own advantages. The characteristics of fiber media converter is information safety, the management and maintenance are easy, but its management and expansion performance is weak. So it is only suitable for small application environment. The outstanding advantage of PON network is that it eliminates outdoor active 

equipment, and all signal processing functions are completed in switches and user’ s

houses. Moreover, the upfront investment of this access mode is small, and most of 

the funds have to be postponed until the user actually accesses it. Therefore, this 

structure can serve home users economically.So it is suitable for large application environment.


Facing the rapid growth of the Internet, as a large-bandwidth transmission method with low deployment cost and high flexibility. PON has been increasingly deployed in transmission access networks around the world. The fiber optical media converter will not be replaced completely because of its unique advantages, especially in the small user number application.
