Is adsl broadband?

Adsl is broadband, and Adsl is actually a kind of DSL.

Technical comparison

From the perspective of technical development, ADSL is a good transition technology, while FTTx+LAN is a more perfect technology than ADSL, and it is a real broadband technology.

Comparison of applicable population

ADSL is suitable for scattered users, FTTH+LAN is aimed at relatively concentrated user groups.

Popularization and consumer cognition

ADSL is a popular product in the broadband market in Jilin Province, which has been widely recognized by the public. Most consumers' awareness and expectation of LAN are gradually improving.

Cost and price comparison

The advantage of fiber-optic broadband lies in the low cost of networking equipment such as hubs and Ethernet switches, and users do not need to install ADSL modems, which is the capital of competition between Ethernet and ADSL. Fiber-optic broadband users have less investment and cheaper cost. ADSL can't be separated from the fixed telephone by using the existing local telephone network and the computer room of the telephone office, and it is limited by the use area. At the same time, the telephone bill also increases the product cost.

Velocity contrast

Due to the asymmetric digital technology of ADSL technology, the speed is asymmetric up and down, and the network speed is limited. The local area network adopts symmetrical digital broadband technology, which has a wider frequency band and variable bandwidth, and can continuously improve the speed. ADSL, on the other hand, has little potential for bandwidth expansion, so it can't meet the demand for access rate in the future market.

Stability and anti-interference

ADSL requires ordinary line quality. When the line quality is not good, it will affect the stability. When the transmission rate is high, attenuation and crosstalk have great influence on the signal, and sometimes the network speed drops and the line is dropped.

FTTX residential broadband adopts a different network from the telephone network. The corridor switch and the cell center switch, and the cell center switch and the local telephone switch are all connected by optical fiber, so the network stability and reliability are high, not to mention the problem of mutual influence.

access mode

FTTX+LAN is FTTH, ADSL is twisted-pair telephone. Relatively speaking, the access of LAN users is simpler and can be accessed by routers, switches or even ordinary network cards. The client uses five types of network cables to access, plug and play. At the same time, because the LAN mode uses optical cable+five types of cables to comprehensively wire the community, the line quality is more guaranteed.

Comparison of business and function

ADSL can support Internet/Extranet/Intranet services, voice services, video services, ATM services, data services, frame relay FR access services and VPN virtual private network services, and can realize Internet interconnection, information sharing, mutual access and transmission.

On the basis of existing ADSL, FTTX+LAN covers all services and functions of ADSL. FTTX+LAN is helpful to build a broadband network system for smart houses, which makes the home terminal and the property management platform form a complete local area network and provides support for property management to carry out various online value-added services.
