Fiber access network devices are still commonly used. So I have studied the functions of the next-generation Metro optical access network devices. I would like to share these functions with you here. I hope they will be useful to you. The ADM622 product series provides carrier-level devices with low costs and flexible services. The PM5337ADM622 and PM5338 ADM 622 PDH Optical Fiber access devices of PMC-siel

If the company decides to deploy an optical fiber channel storage area network (SAN), then it should determine the supplier of the switch, because it is unwise to mix different brands. Fiber Channel switches need to communicate and cooperate with each other to manage the entire network. To ensure that the switches communicate well with each other, the best way is to select one of the three top switch suppli

We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M of fiber, that is 1M b/s =1 M/8 b/S =0.125 MB/

How to Set up a connection between a telecom Optical Fiber cat and a tplink Wireless Router In my home, the optical fiber cat is connected to the tp-link router, one desktop computer, two mobile phones and one tablet computer. I encountered a lot of thorny problems. I checked n more information on the Internet and finally solved the problem. I will summarize it as follows and share it with you. Back to bu

Whether in Wuzhou set up optical fiber or in the Taiping set up ADSL dial-up internet every time you set up the Internet all the time is encountered various troubles ... This time again to get n long, each problem is different. Summary of the operation process, easy to later encounter problems back to query from a microblog.Setting up dial-up internet for telephone lines:1, the voice separator points over the line access all-in-one machine, and then s

According to the ibdn standard, it is generally recommended that the communication room in each building be 12 cores. The building room should use 24 cores for consideration. First, we should know the number of cabling points on this layer and calculate the number of switches, whether or not to stack the connections between switches. If the core switch is dual-host Hot Standby redundancy, 6 cores will be enough (2 cores and 2 cores for each core ). If you do not need to stack a vswitch with 4 co

Of course, we choose the legacy interfaces in Chapter 1 to go to the analysis. Fiber _ Lookup () We mentioned earlier that during fib initialization, The config_ip_multiple_tables macro leads to two methods of Fib table initialization, so there is a situation where multiple route tables exist and no more route tables exist, let's first look at the absence of Multiple Route tables. Static inline int maid (struct net * Net, const struct flowi * handle,

According to Eric eilebrecht's blog, the fiber does not reduce the memory overhead or have better performance. When we need to use a large number of threads (such as more than 100), the total overhead of stack space of each thread increases linearly, and the overhead of thread switching takes too much time, it may even exceed the overhead of program execution. At this time, we need to design a management mechanism similar to the thread pool, and use a

A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem. Fault 1: multiple

The EPON optical fiber access technology is still quite common. So I studied how to increase the network bandwidth of the EPON optical fiber access technology. I would like to share with you here and hope it will be useful to you. With the 1 Gbps fiber-to-the-Home (FTTH) technology, the deployment Speed of EPON fiber a

The optical fiber access network is still quite common. So I have studied the comprehensive solution of the EPON optical fiber access network. I will share it with you here, hoping it will be useful to you. At present, the optical fiber access network is facing a series of technological and business model revolutions and challenges. Changes in user business needs

Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Sparta

A security vulnerability exists in the implementation of the fiber home hg-110. Attackers can exploit this

Fiber To The Home, optical Fiber To The Home, refers To The optical network unit (ONU) installed in The Home user or enterprise user. Its significant technical feature is not only to provide greater bandwidth, but also to enhance the transparency of the network on data formats, rates, wavelengths and protocols, and to relax the requirements for environmental conditions and power supply, simplified maintenan

Hello everyone, our picture is stored with another pat on the Cloud (Upyun). Today, there is a sudden failure: Hangzhou Purple Tunnel construction, and Pat Cloud 2 of the city area fiber are dug, affecting the normal service of the cloud, resulting in 11:00-13:30 can not upload pictures in the garden. This brings us trouble, hope you understand!has been basically restored to normal, but because the use of backup lines, upload speed will be affected by

CISCO mds FC optical fiber switch configuration reference(1) There are several concepts that must be clarified (different from brocade ):(1) brocade divides zones directly. While mds divides zones under vsan, mds can divide several vsan first, and each vsan includes several zones.(2) brocase: the default port is open, while the default port of mds is closed.(3) mds has a Default zone: "The Default Zone ". if no zone is set, all the ports are in this z

Topic Links:https://vjudge.net/problem/POJ-2570Main topic:Some companies decided to build a faster network called the "Fiber network." They have built many sites around the world, and these sites function like routers. Unfortunately, these companies are arguing about the wiring between the sites, so that the "fiber optic network" project is forced to terminate, leaving behind the lines that each company lay
