Along with the social progress and development, as well as people's growing material and cultural needs, communication to large capacity, long-distance direction of development has been an inevitable trend of development. Since the light wave has a very high frequency (about 300 million MHz), that is, it has a very high bandwidth to accommodate huge communication information, so the use of optical waves as a carrier for communication has been the goal of people for more than hundreds of years to

The continuation of optical fiber (1) Fiber continuity. Optical fiber connection should be followed by the principle: when the core number is equal, to the same beam tube of the corresponding color optical fiber docking, the core number is not at the same time, in order to connect the core number of large, and then th

Introduction to Optical Fiber Temperature Measurement Technology in data centers The data center has high temperature requirements and requires 365 days of constant temperature throughout the year. However, in fact, the temperature in different locations is different within the data center. If the ventilation is not good, the temperature in the same data center may vary by a few degrees, in this way, the temperature at the local location is relativel

The dual-fiber access router is the most suitable access method for Internet cafes. So I studied the specific solution of the dual-fiber access router in Internet cafes. I will share it with you here, hoping it will be useful to you. In recent years, Internet cafes have become more and more formal and scaled, and the demand for network bandwidth is also growing. Due to the slow data transmission rate provid

In recent years, with the explosive growth of IP business volume, China Telecom is beginning to develop towards the next generation of Sustainable Development. Building a fiber-optic infrastructure with huge transmission capacity is the physical basis of the next generation of networks. The traditional G.652 single-mode optical fiber has been unable to meet the above-mentioned development needs of ultra-hig

Optical Fiber Laser principles and characteristics I. Introduction Fiber Laser (Fiber Laser) is a device that uses glass Fiber reinforced with rare earth elements as the gain medium to produce Laser output. The fiber laser can be developed based on the

Broadband connection Password Forget what to do? Because the broadband password is not like QQ or mailbox password so often used when we occasionally will not remember, below I teach you a way to see the broadband password. 1, click on the computer in the lower right corner of the display icon, in the pop-up menu click on the right side of the cat-like icon.

"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have? "Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part. and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing, and the name is not standardized, more ambigu

In terms of access network technology, ADSL is a transitional broadband technology, which requires further investment to achieve real broadband. Fiber-optic Ethernet technology is mature and widely used. broadband access is in place in one step. No investment is required. It is the best choice for transmitting voice,

Because the network monitors the long-distance widespread need to use the optical fiber equipment, considers the customer to have the understanding optical fiber connection method The need, therefore below will briefly introduce the fiber optic cable, the terminal box, the tail fiber function and the connection methodT

the shortlisted manufacturer of China Netcom's broadband network equipment selection, Shida network provides a complete broadband IP address resident network solution based on the broadband network construction requirements of China Netcom's Shanghai Branch, this solution provides a broadband IP address resident netwo

PA interface was released earlier, but has been slow to release official documentation, due to the recent customers more, close up this documentBecause PA uses the standard RADIUS authentication protocol, so users need to build a local billing, because the majority of users only hundreds of, do not say to buy a local version of the charge 5000-6000,On the single from the electricity bill, a server, the most common PC also to 120w/h,120w*24*365=1051200, that is, 1000 multi-degree electricity, to

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

MPO/MTP high-density optical fiber pre-connection system is mainly used in three fields: application of high-density environment in data centers, application of optical fiber to building, application of optical fiber to optical splitter, 40G, 100g sfp, connection applications of SFP + and other optical transceiver devices. This article focuses on why MPO/MTP high

In the past two years, with the development of the communication industry and the implementation of national policies, China's FTTH has developed rapidly from the pilot project to the current scale deployment. As an important part of FTTH construction, fiber connection doubles the engineering volume. Meanwhile, the extension of FTTH construction connection point to the indoor environment also brings about a significant increase in the difficulty of wo

Fiber Channel switches are still commonly used. So I have studied the practical application of fiber channel switches. Here I will share it with you and hope it will be useful to you. In the SAN storage architecture, the core devices in the fiber channel switch play an important role in the SAN storage process and affect the network performance.

Almost all projects require performance verification tests on the cabling system after construction. At present, copper cable testing methods, instruments and testing standards have been widely used by practitioners. Compared with copper systems, the popularity of optical fiber testing is much lower. Many projects do not perform fiber link tests, or only use a VFL light source to verify the optical connecti

Today, the competition in the access network market is fierce. When deploying fiber-to-Building (FTTP) networks, it is usually difficult but necessary to make a budget early. This is because business providers should not only consider the initial installation fee, but also the unexpected business operation and maintenance costs. A large number of cost budget models prove that in the design and construction stages, the correct method for connecting FTT

1. Introduction The rapid development of optical fiber communication technology increases the demand for optical fiber cables. At present, hundreds of millions of kilometers of optical fiber has been laid around the world. Optical Fiber Communication is not only used on land, but also forms a submarine cable line span

To build a new broadband community, we have many options, including the Ethernet access scheme, ADSL access scheme, Cable Modem and hfc-network scheme, and optical fiber access scheme. How should we choose these access solutions? Different solutions vary in application scenarios. Let's take a look at the features of several access solutions. High-speed Ethernet solution In the
