What is the reason for the slow Internet speed of Optical Cat?

1. Contracted bandwidth issues

Generally, if the contracted bandwidth is not up to standard, the first thing people think of is the problem with operators such as China Telecom, China Netcom, China Unicom, China Mobile, and Radio and Television< /p>

Solution: Call the operator’s customer service number, and they will usually help the user refresh the phone. It is recommended that the user unplug the optical modem and reconnect for 5 minutes to test. However, most users have done the above operations, but the problem is still not solved. Then we have to consider the router issue.

2. Router problem, is the router a Gigabit router?

If your home still uses a Gigabit router, what is the WAN port? 10/100M adaptive, the highest bandwidth output is 100M, but the access is 200M, 300M, or even 500M contracted broadband. This definitely means that the bandwidth is not up to standard and bandwidth resources are wasted.

Solution: Replace For Gigabit routing, it should be noted that some merchants also promote WAN/LAN ports as Gigabit routers with 100M ports. When purchasing, be sure to pay attention to whether the WAN port supports Gigabit

3. Problems with the connection line between the optical modem and the Gigabit router

If there is no problem with the contracted bandwidth and Gigabit routing, then there is a high probability that the problem is with the optical modem and the Gigabit router. If the connection line between the modem and the router is not a Category 6 network cable or above, it does not support Gigabit bandwidth. For example, if you use an ordinary Category 5 network cable, the maximum bandwidth is only 100M. Even if you use a Gigabit router, the maximum bandwidth of ordinary websites before optical modem and Gigabit routers is only 100M, so in theory, the maximum routing bandwidth is only 100M

Solution: Replace Category 6 network cable or above Category 6 network cable

Summary: To solve the problem of sub-standard contracted bandwidth, the main issues are the operator's bandwidth, whether the router supports Gigabit WAN port, and whether the connection cable between the optical modem and the Gigabit router is Category 6 network cable or above. After understanding these key links, It can easily solve the problem of less than 100M in actual use test.

1. Check the connection between the optical modem and the optical fiber. Check whether the connection between the two is normal, and be careful not to use too much force when reconnecting.
2. If the optical fiber is squeezed, collided, etc. during use, and the optical fiber is damaged, regardless of whether the crack is obvious or not, you need to contact fiber optic broadband maintenance personnel to repair it.
3. Due to the problem caused by the optical splitter failure, you need to power off the optical modem, wait for a period of time, and then restart the optical modem. This problem will be solved soon.
