News that China Telecom will not abandon the coexistence of DSL and fiber to the home

For testing prior to the disclosure of VDSL2 replace the current ADSL, fixed-line speed to enhance the number of times, informed sources, this does not mean that China Telecom would give up the fiber to the home, but will also take VDSL2 and XC9572-10PC84C datasheet and Fiber to the household technologies, both fixed-line means to proceed with great speed increase.

FTTH and XC9572-10PC84C price and VDSL2 are not contradictory

Previously reported that China Telecom is vigorously testing high-speed broadband fixed-line, one of which is the rate of Internet users in theory, will increase the number of times. The first phase of the pilot in Guangdong Foshan and XC9572-10PC84C suppliers and Guangzhou to carry out. VDSL2 offers up to 100M copper-based up and down the line rate. Which, in Foshan, Shanghai Bell, ZTE in Guangzhou.

For the use of VDSL is fiber to the home will not improve with home broadband network speed, the industry denied this and said that China Telecom and China Unicom will also take VDSL2 and FTTH technology for fixed-line broadband technology, the current Both are in the pilot stage.

Compared to VDSL, FTTH is more familiar. In 2007, China Telecom, the country began to put the fiber to the home of four pilot operations, the only pilot in Wuhan over 2 million users.

Thereafter, China Telecom and China Netcom to continue to implement fiber to the home of the original trial, even after last years snow disaster and the Sichuan earthquake, announced the introduction of light into the copper are pushing vigorously laying of optical fiber, fiber to the home to prepare for the future. Users to enhance the familys expectations higher and higher speeds.

Coexistence of two simultaneous broadband speed technology

Using VDSL2 with the use of GPON, EPON FTTH technology, can achieve a rate of 100M, operators how to choose?

Stakeholders Shanghai Bell explained that the existing broadband access technology is ADSL, which is based on twisted pair, and its carrying capacity by increasing the bandwidth challenge, therefore, the "light into the copper," the implementation of the telecommunications sector network evolution steps.

ADSL twisted-pair network of resources that already exist for many years, mass deployment, mature applications, and contrast, fiber-optic network (especially fiber laying) the high initial construction costs, allowing operators have to carefully consider the fiber deployment schedule. Especially in China Telecom and China Unicom with a large number of twisted pair resources, therefore, the use of existing resources to provide higher bandwidth services as the most economical and best access network solutions.

In this case, the equipment manufacturers have therefore developed a derivative of ADSL technology ADSL +, VDSL2, etc., not only can provide high bandwidth, and also to maximize use of existing twisted pair resources.

Industry that, DSL and FTTH deployment of hybrid technology, the next few years will be widely adopted in building our broadband strategy.

Price comparison

In addition, the industry pointed out, VDSL2 is based on Ethernet technology. Relative to the fiber access, VDSL2 in the economic cost and ease of use has obvious advantages.

However, long-term trend, as prices of copper materials, while the cost of optical access is gradually decreased, as FTTH, fiber to the building provides the opportunity for development. However, EPON FTTH technology or using technology in the end with GPON technology, and there is a huge controversy.
