The value of optical fiber networks is under review

The value of optical fiber networks is under review

With the popularization and application of high-definition TV, 4G technology, and high-speed transmission network information, the traditional Integrated Wiring technology environment has been overturned. In addition, in the context of high bandwidth acceleration, telecom operators began to gradually push forward copper to the FTTH optical fiber access mode. But at the same time, operators are also facing difficulties and cost pressures in deploying and constructing optical fiber cables to their homes. As a result, FTTH construction is slow, the project cost is high, and home decoration is damaged. This makes it almost a luxury for many mature community users to enjoy the ultra-broadband network. Therefore, the use of optical fiber access or copper access requires a review of the value of both parties.

The light and copper in the current background still coexist for a long time.

Fiber-to-the-home has become a mainstream technology that meets users' ultra-broadband network needs, and has become a standard for more new residential buildings. However, for most mature communities, fiber-optic transformation involves complex projects such as fiber-optic cabling and home fiber cabling, resulting in slow FTTH construction progress, high engineering costs, and damage to home decoration, this makes it almost a luxury for many mature community users to enjoy ultra-broadband networks.

In addition, the three major operators have a large amount of copper resources, which may cause a great waste if they are not used. To comprehensively promote broadband acceleration, it is necessary to consider how to use existing resources to avoid repeated construction. Therefore, on the one hand, the user's demand for network bandwidth is almost hunger and thirst, on the other hand, it is helpless that FTTH cannot be fully popularized. What should operators do in the face of such a situation?

In this situation, the industry has been researching and solving ideas, and finally put forward the development ideas of light copper complementing each other. It can be learned from the cabling vendor that, if we can use the complementary construction ideas of copper light and reuse existing "copper wires" to provide users with ultra-broadband access, the construction of ultra-broadband networks will be greatly accelerated, this has also become a pillar of the carrier's mid-term broadband network strategy. From this point of view, the value of copper speed-up technology in the broadband speed-up construction of operators has begun to be highlighted. Copper-light complementarity may coexist for a long time in the future.

G. fast leads Copper connections to the Gigabit age

Looking at the application of the entire industry, we can see that the user's demand for bandwidth is endless. To break through Mbit/s or even reach a gigabit rate, we need to introduce an updated access technology. At present, G. fast technology is very promising to bring up the "copper wire access into the Gigabit era.

It is understood that G. fast technology can achieve 1 Gbps ultra-broadband access on existing copper wire resources (telephone lines or coaxial cables. In the future, G. fast technology may be mainly used in FTTB/FTTD scenarios that are less than 250 M away from the end user, with a target bandwidth of 500-1000 M per household. As you are closer to the user, you can get a relatively higher bandwidth, and G. fast will be used as a gigabit access solution comparable to FTTH.

Unlike previous technologies, G. fast introduces user-defined concepts at the initial stage of standard design. Traditional copper wire access technologies, both ADSL2 and VDSL2, are fixed upstream and downstream bandwidths. In most cases, the downlink bandwidths are large and the uplink bandwidths are small. In the cloud business era, end users may need to share a large amount of HD videos or images. At this time, the uplink bandwidth is too slow to become a bottleneck. G. fast technology allows operators to define their own upstream and downstream bandwidth based on their actual network services. For example, some operators define the upstream bandwidth as Mbps or Mbps, or Mbps, this will further help carriers improve their broadband network capabilities and user experience.

At the same time, the G. fast technology introduced the concept of self-installation in the early stage of the standard design. For carriers, G. fast technology is usually deployed at the FTTB/FTTD location. It supports reverse power supply on the user side. The carrier can be plug-and-play without being limited by the power supply location. The user-side terminals are also as easy to use as ADSL2, and end users can complete their own installation to implement plug-and-play.

Similar to the advantages of Fiber-to-user bandwidth rate and simple and convenient installation and construction, we can predict that G. fast technology will have a huge market space in the future. For users who have deployed FTTC/FTTB/FTTD VDSL2. fast technology is upgraded. In FTTH Network Construction, FTTB/fttd g can also be used to obtain bandwidth equivalent to FTTH in mature community transformation environments. the fast solution greatly reduces the FTTH entry cost and activation cycle.

The value of copper cables must be recognized under the idea of optical copper complementary cabling

In today's long-standing coexistence of multi-generation broadband access technology, which Broadband Access Technology Based on copper resources is more suitable for creating ultra-broadband networks for users? In this research project, the G. fast technology has made new breakthroughs, taking on the new model of optical copper and setting up the banner of "copper access into the Gigabit era. With the new wiring idea, copper cable value once again ushered in a beautiful spring.

Recently, the selection of optical fiber and copper cables has caused a lot of controversy at various levels. In the information high-speed era, optical fiber seems to be the best and ideal medium, and is also an inevitable product of the development of the information industry. As the optical fiber industry is booming, various application problems emerge one after another. For example, costs, construction, and actual market demands all curb the popularization of fiber access. However, copper cabling once again emerged in the context of seemingly obsolete cabling, and its application value was recognized again.

With regard to the application prospects of copper cables, they have been interviewed with some well-known brand technical engineers. They have expressed their comments: "copper cables are still the current application trend ". According to their knowledge, more than six types of copper cables can fully meet the actual needs of customers in the current market. From the sales data of major manufacturers, we can also see that copper cables occupy a large proportion. I once said this in an exchange with nexson technical engineers. To learn about the application market of optical fiber and copper cables, the simplest thing is to consider whether the current computer network access port is an optical fiber port or a copper port, perhaps such a simple data analysis can tell the answer that copper is still the mainstream application, and its value will continue to be highlighted. Production Enterprises are constantly increasing R & D efforts for high-end copper cable applications, and re-recognize the value and market demand of copper cables.
