The flashing red light of the light signal means that the light signal is interrupted. Reasons and solutions: 1. The indoor pigtail connection optical modem connector is loose or has poor contact. You need to unplug the interface, clean it and then plug it back in; 2. Excessive bending of the optical fiber affects the transmission of optical signals. Just straighten the optical fiber. ; 3. If the optical fiber is broken, you need to contact maintenance personnel for rewiring; 4. There is a problem with the optical modem optical interface, please contact maintenance personnel to repair or replace an optical modem; 5. Broadband arrears, just pay the arrears; 6. Regional broadband failure Or system problem, wait for maintenance personnel to repair the broadband.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Nowadays, many broadbands need to be equipped with a router to receive optical fiber signals after installation. There are several indicator lights on the router. If your router’s signal light keeps flashing red, do you know what it means? Let’s find out together.

The optical signal flashes red, which means the optical signal is interrupted. The reasons and solutions are as follows:

1. The optical cat connector of the indoor pigtail connection is loose or has poor contact. In this case, you need to unplug the interface, clean it and then plug it back in again.

2. Some indoor optical fibers are bent too much. Excessive optical fiber bending will affect the total reflection transmission of light signals in the optical fiber. Just straighten the optical fiber.

3. The optical fiber is broken. When the bending angle of the optical fiber is too large, the inside of the optical fiber has been broken, causing the optical signal to be unable to be successfully transmitted. Just contact the maintenance personnel to re-wiring.

4. There is a problem with the optical interface of the optical modem. This situation is a hardware problem of the optical modem. If there is a problem with the optical modem interface, the optical signal will not be transmitted to the optical modem. Contact maintenance personnel for repair or replace it with a new one. Just the cat.

5. Broadband arrears. Nowadays, broadband services are basically post-paid. Operators will shut down broadband services due to customer service arrears for too long. In this case, you only need to pay off the arrears.

6. There is a regional broadband failure. The broadband in the entire area may be under maintenance or has a fault and needs to be repaired. In this case, you can call the customer service number to find out the situation and wait for the maintenance personnel to repair the broadband.

7. System problem. If the entire area has been shut down, there is a problem with the system. Just wait patiently, or contact customer service to explain the situation.

Different optical fiber access technologies have different applicable occasions:

Active optical access technology is suitable for large bandwidth requirements, Access to enterprises and institutions with high communication confidentiality. It can also be used in feeder and distribution sections of access networks and mixed with other access technologies based on wireless or copper wire transmission.

ATM-PON can be used to provide access to both enterprise and institutional users as well as residential users. Some operators use the "ATM-PON+xDSL" hybrid access solution to provide broadband access for residential users or enterprise users.

Router introduction:

A router can also be called a gateway device. The router is the network layer relay and third layer relay tasks completed in OSI/RM. It stores and forwards data packets between different networks. Its main purpose is to separate the networks in different logics. Data transmitted from one subnet to another can be processed through the routing function of the router. In network communications, routers have the function of determining network addresses and selecting IP paths. They can build flexible link systems in multiple network environments and connect various subnets through different data grouping and media access methods. During operation, the router only accepts information transferred from the source station or other related routers. It is an interconnection device based on the network layer.

Function:

Connect the devices of various LANs and WANs in the Internet. It will automatically select and set the route according to the channel conditions, and use the best path. Send signals sequentially. It can greatly increase the communication speed, reduce the communication load of the network system, save network system resources, and improve the smoothness rate of the network system, so that the network system can exert greater benefits. Network interconnection: The router supports various LAN and WAN interfaces and is mainly used to interconnect LANs and WANs to enable different networks to communicate with each other. Data processing: Provides functions including packet filtering, packet forwarding, priority, multiplexing, encryption, compression and firewall. Network management: The router provides functions including router configuration management, performance management, fault tolerance management, and flow control.

Introduction to Light Cat:

Optical modem, also known as optical modem, refers to network equipment that transmits through optical fiber media and modulates and demodulates optical signals into other protocol signals. It is a relay transmission equipment for large-scale local area networks, metropolitan area networks and wide area networks. . It has complete alarm status indication and complete network management functions. The device consists of sending, receiving, control, interface and power supply parts, and uses large-scale integrated chips. The optical cat has simple circuit, low power consumption and high reliability. The optical wavelength of the optical cat is 1310nm.

Advantages:

The principle of optical cat is the same as that of ordinary broadband cat, but its function is more complete than ordinary broadband cat. It can be directly connected with optical fiber. Connect so that we can use a faster network.

Light modems can also be used to install wireless networks, but the process is more complicated. During the setup process, if the data is accidentally disturbed, the modem may be useless, and the router may not be usable, so I don’t know much about it. For those of you, it is best not to set it casually, but just connect it to the router, which is easier to use.

How many lights on the router are normal? 'Recommended detailed explanation of the normal status of the router indicator lights' How many lights on the router are normal? 'Recommended detailed explanation of the normal status of the router indicator lights' Feb 06, 2024 pm 09:12 PM

The first light is on, indicating that the router is powered on. Which port is plugged in, the light of which port is on, and flashing means data is being transmitted. Wireless routers usually have three indicator lights: SYS, LAN and WAN. When the wireless router is powered on, the SYS light will light up. When the wireless router is connected to the network modem, the WAN light will light up. The LAN light corresponds to each interface of the wireless router. As long as the network cable is inserted into the corresponding interface, the corresponding LAN light will light up. 1. If it keeps flashing, it means it is transmitted by data, and the router settings should be normal. 2. If you have always been able to access the Internet, but you can't get online recently; it is probably a problem with the external line, that is, a problem with the operator (usually there is a problem with the line, causing the data signal to attenuate too much, although the line is good)

What are the benefits of turning on ipv6 on the router 'Advantages of using the latest IPv6' What are the benefits of turning on ipv6 on the router 'Advantages of using the latest IPv6' Feb 06, 2024 pm 05:34 PM

Students who know computers all know that if our computer wants to connect to the network, it must have an IP address. This IP address can be manually configured, such as 172.16.19.20; it can also be automatically obtained by the DHCP server of the computer network card, such as 192.168.1.100 etc. These IP addresses are what we often call IPV4 addresses, and the corresponding IPV6 is also a type of IP address. What is IPV6 IPV6 is a new IP address that emerged in response to the exhaustion of IPV4 address resources. Its full name is "Internet Protocol Version 6", and its Chinese name is the sixth generation of Internet Protocol. The number of IPv6 addresses is theoretically 2^128
