Preface:Sharetop is the first choice for optical expansion. We have 15 years of experience in optical communication and transmission industry, serving more than 1000 industry customers, and providing customers with professional, stable and reliable optical transmission solution service provider -- Sharetop.
Today we will talk about the application of wave division transmission equipment in data center room.
With the rapid development of the Internet in the last decade and the emergence of various apps, unimaginable things can be accomplished without leaving home. You don't want to travel, but you can see the scenery of Mount Qomolangma online in real time through mobile phone or TV at home. Doctors can operate on patients thousands of miles away by remote control. Do not want to cook, order a takeout within half an hour of steaming food delivered to your hands, all these convenience and efficiency can not be separated from the support of the data center behind.
All kinds of apps, software, or Internet technology need to be carried by hardware, app is carried by mobile phones, public software services or cloud computing/big data/artificial intelligence/blockchain is carried by IT hardware, and IT hardware is living in a place called the data center.
Houses come to live in, but not necessarily people. A data center is a house that houses all kinds of IT equipment. The design of the data center's housing type map, feng shui electricity, temperature and humidity, fire prevention and theft prevention, etc., is for the comfort of the machine to live, based on the machine.
Data center is the infrastructure of IT industry, is the real estate of IT industry, the development of Internet technology to these infrastructure is more and more demand.
The residents of the data center are servers, storage, switches and security equipment, and the property is the operation and maintenance personnel of the data center. The data center provides computing and storage services. Servers, PCS, and smartphones also provide computing and storage services, but data centers are large and covered with buildings rather than plastic. In fact, the data center is a large room, there are many many servers, dedicated to the centralized management of data (storage, computing, exchange). Data Center, English abbreviation is IDC, is also the Internet Data Center (Internet Data center).
So what is the key role of the wavelength transmission equipment in the data center?
1. Save optical fibers
One of the bandwidth costs of data centers is the cost of optical fiber resources. The more fiber cores rented, the more expensive the cost. Wavelength division transmission equipment can be directly multiplexed and expanded on the original 2-core fiber, and the 2-core can be changed into 20 or 40 or even 80 core. Most IDC customers already know that wave division can be used to solve the problem of inadequate cable resources.
2. Build a backbone network
The upper layer backbone network of a data center has a large bandwidth, with each port exceeding 100 Gbit/s. If a wave division device is used for networking, a maximum bandwidth input of 80X100G/200G and a maximum of 16 Gbit/s can be achieved to meet the bandwidth output between cities or bandwidth inbound and outbound requirements of some small countries.
3. Pure transmission, low delay
Most customers of data centers have high requirements on the network. For example, bank customers have very high requirements on the delay. As the wavelength division transmission equipment is pure transparent transmission and does not do any analysis and processing on the data, it only generates very low delay, which is about 1 millisecond delay for the transmission of 100 kilometers.
4. Suitable for ultra-long distance transmission
Many services of the data center are across many cities, and even across provinces and countries. The transmission distance is dozens or hundreds of kilometers, and some even thousands of kilometers. The longer the distance, the higher the rental cost, at this time, the wavelength division transmission equipment can play a maximum value in the cable laying. It has circled the whole country and passed through more than 40 machine rooms. Currently, the equipment has been running stably for more than 6 years. Next, users need to upgrade and expand the wavelength division port.
So far, my friends in the data center industry, you want to buy
