The Application of Fiber-Optic Ethernet switches is becoming more and more extensive. Here we mainly introduce the ACCESS scheme of fiber-optic Ethernet switches and its practical application problems. The fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, that is, Ethernet and optical network. It
Optical Fiber Communication is a communication mode in which various electrical signals are modulated by optical fibers. Optical Fiber Communication is different from wired communication. The latter uses metal media to transmit signals, while optical fiber communication uses transparent optical fiber to transmit light
4G investment over 240 billion Optical Fiber splitters will increase in demand
By 2014, China Mobile will build 0.5 million base stations with an investment of more than 240 billion yuan. The 4G wireless network will cover 340 cities and strive to expand 50 million 4G users, with the arrival of the 4G era, the demand for optical fiber splitters will increase dramatically.
Mobile communication is wireless a
When selecting the right optical cable for the data center, the application, distance, data transmission rate, and the difficulty and cost of future upgrades should be taken into account. Multi-Mode Optical Fiber has always been the choice of enterprise system network connection structure (ESCON) and related Switch Networks, and most modern SAN and LAN also adopt multi-mode optical fiber. Other applications
Broadband access network technology is still developing very rapidly. It does not matter if many people are not familiar with the fiber-based broadband access network technology. After reading this article, you must have gained a lot, I hope this article will teach you more things. With the emergence of optical fiber technology, optical fiber-based access network
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.

Youxun vro's optical fiber settings many netizens use fiber-optic access for broadband. They do not know how to set up routers. This article uses the D-Link vro as an example, the basic configuration, Security Service, and P2P settings in the optical fiber settings are described in detail. 1. Optical Fiber-Optic conver
-tube unit
A micro-tube unit is composed of a silicon core layer added to the inner wall of HDPE material. Generally, the inner wall with a diameter of more than 5mm has a flow channel, the inner wall of the microtube diameter below 5mm does not have a flow channel. At present, the external diameter of the micro-tube generally ranges from 3mm to 16mm. The number of fiber cores that can be accommodated in one microtube ranges from 1 core to 288 cores o
first, 100m fiber download speed can be how much
According to the theoretical data can achieve 12.5m download speed, theory, but the actual download speed can not achieve this high, because the decision to download the speed of a number of factors, there are access to the Community network cable problem (network cable too long or substandard quality will affect the speed), there are user computer problems and operating system environment problems, So
During the establishment of a LAN, according to the general standards of Integrated Wiring, the construction should use a network cable with a "meter" or a special "shaped number tube" at the crystal head on both sides ", the computer identification records corresponding to the "meter mark" or "number tube" are recorded in the cabinet.
Many units have a small number of computers. Later, some computers were added to form an inevitable lan. However, when the network was originally set up, the netw
1. What is GBIC?
GBIC is short for Giga Bitrate Interface Converter. It is an Interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBIC is an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange.
2. What is SFP?
SFP is short for small form pluggable. It can be understood as an upgraded version of GBIC. The size of the
This content is nothing for experienced friends, but it can be useful for new users who just entered the industry.
There are two types of optical fibers:
Single-mode Optical Fiber Single-mode Fiber): Generally, the optical Fiber jumper is yellow, the connector and protective sleeve are blue, and the transmission distance is long.
Multimode Optical
The help Command for partitioning zones of Optical Fiber switches prompts you how to perform this operation. Zonehelp prompts you how to operate zones. Zonecreate command to create a zone. Command: zonecreate "zone_name", "number; number ". Here, number can be "domain, port number", "wwn", zone alias, and Quickloop AL_PAs. The default vswitch domain is 1 and the port number ranges from 0 to 15. You can use switchshow to view the configuration. It is i

Advantages of Optical Fiber
As the successor of SCSI technology, fiber channel technology has three main advantages compared with its predecessor: Connection distance, scalability and performance.
1. Advantages of connection distance
We all know that SCSI Cables cannot exceed 25 m at most, and this is only a theoretical value. In practice, when the number of devices on the SCSI channel exceeds 8, the connec
The optical fiber access network is still quite common. So I studied the optical fiber access network equipment in Internet cafes and shared it with you here. I hope it will be useful to you. As customers have higher and higher requirements on Network Stability and speed, the network devices required for Internet cafes must also have higher stability and reliability to ensure uninterrupted and stable networ
