Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails.
Optical fiber jumper (also known as optical fiber connector), that is, the optical fiber connectors connected to optical modules, also have many types, and they cannot be used with each other. The SFP module (SFP (Small Form-factor Pluggables) can be simply understood as
placed in the 100 BaseTx module, 100 baseFx module, or even the ATM module and Gigabit Ethernet Interface Card (GBIC ). C2912-XL: 12 port 10/100 BaseTx adaptive C2912MF-XL: 2 expansion slots, 12 port 100 BaseFX C2924-XL: 24 port 10/100 BaseTX adaptive C 2924C-XL: 22 port 10/100 BaseTX adaptive, 2 port 100 BaseFX C 2924 M-XL: 2 expansion slots, 24 port 10/100 BaseTx adaptive in the 2900 series, two products are unique, one is C 2948G, the second is C
There are many users who use Cisco switches. When selecting their products, it is a headache to see Cisco switch models. Here we mainly explain how to quickly understand these complex Cisco switch models. The product line of the 2900 series is very long. Some of them are common 10/100 BaseTx Cisco switches, such as C2912 and C2924, some are with Optical Fiber interfaces, such as C2924C with two 100 BaseFx ports, and some are modular, for example, C 2924 M has two expansion slots. The expansion s
Let's take a look at the built-in user interface and detailed functions of Netgear to see what it can do.

Open the machine and connect to your computer with a network cable. in the address bar of your browser, enter the default vro192.168.address 192.168.1.1 of Netgear. During the first use, it has a wizard to help you use it for the first time, you can complete the basic configuration step by step.
Describes how to set up a home wireless local area network articles, you can search out a lot of online, these articles look very good, not only the details of the process described with the relevant pictures. Because of professional reasons, although I used to pay attention to the wireless router configuration in this respect, but because there is no actual operation and flow on the surface, the last few days can not resist the temptation to do a set of Net
Maybe many people are not very familiar with how to buy a wide M Wireless Broadband Router. Next we will mainly explain the purchasing skills of the wide M Wireless Broadband Router. The quality of vro products on the market is uneven and prices vary greatly. This is the case for products of the same grade, not to mention products of different grades. Therefore, it is really necessary for consumers to make more efforts when purchasing vrouters. Next we will introduce the two TP-LINK TL-WR642G an

This article describes how to set up a wireless LAN for a home. You can search a lot of articles on the Internet. These articles seem very good, not only the detailed process description, but also related images. Because of my career, although I used to pay attention to the wireless router configuration, I failed to follow the surface because I didn't have the actual operation. A few days ago, I was tempted to build a set of NETGEAR) in the wireless p
"IT168 technology" with the increase in mobile terminals, the demand for wireless routers more and more high, I do not want to buy a wireless router, I searched the internet, and found that the wireless router can be brush "ddwrt" to increase the function, we are a very strong hands-on ability, but also not afraid of brush bad, I decided to brush my Netgear WNDR3400 wireless router to see the effect.
The first thing to say is that any manufacturer ha
This article describes how to set up a wireless LAN for a home. You can search a lot of articles on the Internet. These articles seem very good, not only the detailed process description, but also related images. The lessons learned are shared with you.
The wireless router uses NETGEAR WGR614 (54M is 802.11g), and the NIC is also 54M (the configuration is very smooth, so I did not carefully look at the specific model). The reason why
controller maintains the authentication and encryption status of the client.
3. Independent controller roaming (only one wfs709tp in the environment)
1. l2 (Layer 2) Roaming
Note: AP1 (1.1.1) and AP2 (1.1.2) are on the same wfs709tp, And the broadcasted SSID is the same and on the same VLAN. When the client is roaming from 1.1.1 to 1.1.2, the IP address and encryption of the client are maintained in wfs709tp. During the roaming process, no IP address changes or re-Authentication occurs. Only
From the data, we can see that the current market demand for gigabit backbone switches is not high. Here we mainly analyze the functions and practical applications of mainstream Gigabit backbone switches. In the six Ethernet switches we tested, the EDIMAXES-5800R and LeaPComm6004 switches are not manageable switches, The Accton es00008 and the Thinker3800 switch of the Creative Company are all network tube switches, 3Com4900 is a layer-3 and layer-4 switch, and digital China D-Link DGS3308TG is
Ethernet switches are still commonly used, so I studied the high availability of stack 10/100 Ethernet switches. I would like to share with you here, hoping to be useful to you. Catalyst3524-PWRXL Ethernet switches are part of the CiscoSystemsCatalyst3500XL series, which is a series of scalable stack 10/100 and Gigabit Ethernet switches that provide optimal performance, manageability and flexibility, as well as unparalleled investment protection.
Advanced service quality QoS) is fully integrated
Currently, the mainstream Gigabit backbone switches have high forwarding capabilities and smaller sizes. They are suitable for common users. Among the six Ethernet switches we have tested, EDIMAX ES-5800R and LeaPComm6004 switch is not manageable switch, Accton es00008 and creative company Thinker3800 switch are network tube type switch, 3Com 4900 is support Layer 3 and Layer 4 switch, digital China D-Link DGS3308TG is a layer-3 switch.
Performance first
Among the six products, there are both fu
Several Optical Fiber interfaces (ST, SC, LC, FC)I have never been very clear about Several Interfaces of optical fibers. I have seen real images on the Internet and shared them with you. The optical fiber is sometimes annoying and summarizes several commonly used optical fiber connectors.The above figure shows LC to LC. LC is the SFP commonly used by routers and the line head inserted by mini GBIC.FC to SC, FC End Plug fiber step frame, SC end is catalyst or other or above
Cisco has become a leader in the communication industry, and its product performance is still very good. Here we mainly explain the common problems and solutions of Cisco switches. Here we will share with you some of them, I hope it will be useful to you.
