Dedicated lines, that is, independent lines, are directly connected through optical fibers from the operator's metropolitan area network to users, and are truly independent bandwidth lines.

In contrast, fttp in the home is actually a kind of * * * broadband, which reaches the user's home after primary and secondary splitting. In some areas or when the traffic is very large, the independence of bandwidth cannot be guaranteed.

Because fttp adopts GPON/EPON technology, downlink adopts broadcast technology and uplink adopts time division, the delay is longer than that of dedicated line. Now some users who are particularly sensitive to delay will choose private line access, such as stock trading or foreign exchange.

The after-sales service level of private line is much higher than that of home broadband. According to the current relevant regulations, the troubleshooting time for home broadband is 48 hours or 72 hours (although some operators propose to repair the fault on the same day), and the troubleshooting time for private lines is generally every hour.

Generally speaking, the uplink and downlink of the dedicated line will be the same. For example, a dedicated line of 100M can be 100M downlink/100M uplink, and the corresponding home fiber broadband is 100M downlink /20 m uplink, so a dedicated line is required for services with high uplink requirements.

The price of private line is far more expensive than that of family fttp. Now, with the promotion of speed-up and fee reduction by the Ministry of Industry and Information Technology, the price of home broadband has dropped sharply. If there is a converged service, mobile phones can get broadband for free when they reach a certain package level.

Private line has no IPTV service, but pure data service, which is different from home fttp broadband and has telephone and IPTV services. But the private line can get a fixed IP, which is also the advantage of the private line.
