After several years of deep cultivation, the mystery of the routing mode of OLT optical cat equipment

1. Two working modes of OLT optical modem equipment

The broadband installed now is basically the fiber optic cable to the home, the fiber optic cable to the home access method, and the optical modem is a must have network equipment. OLT optical modem devices are generally uniformly equipped by operators. When installing broadband configuration optical modems for users, installers enter the LOID code (logical ID) on the OLT optical modem device management page to register optical modems. The parameters configured in the operator’s computer room will be remotely issued to the optical modem, which of course includes the optical modem’s super management password. In most areas of the country, the optical modem works in routing mode with the parameters configured by the operators.

There are two working modes of OLT optical modem equipment, one is the bridge mode, this mode optical modem only performs photoelectric conversion, and the computer or wireless router performs PPPoE dialing; the other is routing mode, this mode optical modem not only needs to perform Photoelectric conversion is also responsible for PPPoE dial-up. At this time, the optical modem also acts as a router and also serves as a wireless router.

2. Optical cat bridge, wireless router dial-up is more user-friendly

In the two working modes of OLT optical modem equipment, in routing mode, optical modem completes PPPoE dialing (optical modem wireless signal is weak, coverage is too small, generally not used), wireless router is connected to optical modem, and other devices are connected to wireless router. Under the second-tier LAN. An extra layer of LAN means an extra layer of NAT data conversion, especially when connecting to the upper-level equipment through a WAN port, NAT browsing the web, watching videos, and games are slower and the network experience is not good.

In the bridge mode, the wireless router dials, and all the devices behind the router are under the first-level LAN. Only one NAT conversion is required to connect to the external network, and the network is smooth. For game applications, the NAT type requirements are high. In this mode, the host is set to a static fixed IP, and the wireless router is set to point to the host, which can greatly improve the NAT type, increase the game connection speed, and the network experience is very friendly.

3. Pros and cons of the two working modes of optical cat

When the operator installs broadband, one of the reasons why the optical modem is set to work in the routing mode by default is that the setting is simple. The OLT optical modem device can directly access the Internet after registration. The wireless signal requirements are not high, and a wireless router is omitted. Directly use the wireless Internet of the cat. Even if the wireless signal requirements are high, you only need to prepare a wireless router to directly plug into the optical modem network interface, without too much professional setup and operation. In addition, optical modems have fewer routing functions and lack various advanced functions such as manual port mapping that wireless routers have.

Setting the optical modem to the bridge mode requires certain professional knowledge. First, the user needs to know the super management password of the optical modem to log in to the optical modem management page and modify the bridge mode. Second, improper settings can easily cause the user to fail to connect to the Internet. Report broadband failure to the operator. Therefore, under normal circumstances, the operator’s computer room will issue a dynamic super password and will not tell the user. This is to prevent the user from modifying the optical modem at will, causing network failure. The setting of bridge mode is complicated and difficult.

4. The big picture of operators-with a long-term vision, and start working hard for several years

In fact, in addition to reducing work links and reducing the failure rate mentioned above, it has recently been discovered that there is a more important factor. In the routing mode, operators create their own ecological environment.

The optical modem has a USB interface, which can be plugged into a U disk. The optical modem works in the routing mode, and all the devices connected to the optical modem can access the U disk data through the network neighbors to create a NAS for the local area network. In addition, the optical modem has a remote download function. After adding an FTP or HTTP download address, the optical modem can automatically download files to the U disk, which is convenient and quick.

This year, operators began to promote the concept of smart home. After the mobile phone is installed with the APP, it can use some value-added functions, such as smart speed-up, game acceleration, and management of networked devices through the APP. The promoted WiFi whole-house wireless router and AP combination is more It is tailor-made for the weak wireless signal of the optical modem under the optical modem routing mode. Since 2015, the optical fiber and copper retreat have been basically put in place. Almost all network cables have been upgraded to optical fiber cables, and optical modems have entered thousands of households. Over the years, a large number of optical modems have been working in the routing mode. This is a big game. The operators have been working silently for these years. It turns out that there is a big pattern. This is the mystery of the optical modem routing mode. Everything is for the promotion of wisdom today. In the family, around the optical modem to sell WiFi whole-house wireless routers to various smart devices to users, many devices need to open value-added services.

Today, mobile phone users are almost saturated and new user growth is weak. Operators create new revenue growth points from other aspects. Only with great wisdom can we enjoy the fruits of technological progress.
