Today we will talk about the application of wavelength division transmission equipment in data center computer rooms.

The Internet has developed rapidly in the past ten years, and various APP applications have emerged one after another. You can accomplish all kinds of unimaginable things without leaving home. If you don’t want to travel, you can see the scenery of Mount Everest online in real time through your mobile phone or TV at home. Doctors can Perform operations on patients thousands of miles away through remote control, or order takeout if you don’t want to and have steaming hot food delivered to you within half an hour. All these conveniences and high efficiency are inseparable from the support of the data center behind it.

Various apps, various softwares, or Internet technologies all need to be carried by hardware. Apps are carried by mobile phones, and public software services or cloud computing/big data/artificial intelligence/blockchain, etc. are carried by IT hardware. IT hardware all lives in a place called a data center.

Houses are for living in, but not necessarily for people to live in. A data center is a house specially used to house various IT equipment. The data center’s floor plans, wind, water, electricity, temperature and humidity, and fire and theft prevention are all designed to make the machines comfortable and machine-oriented.

Data centers are the infrastructure and real estate of the IT industry. The development of Internet technology has placed increasing demands on these infrastructures.
The residents of the data center are servers, storage, switches and security equipment, etc., and the property management personnel are the operation and maintenance personnel of the data center. The data center provides computing or storage services to the outside world. Servers, PCs, smartphones, etc. also provide computing and storage services to the outside world, but the data center is larger and the shell is made of buildings instead of plastic. In fact, a data center is an oversized computer room with many servers dedicated to centralized management (storage, calculation, and exchange) of data. Data center, the English abbreviation is IDC, which is Internet Data Center.

So what key role does wavelength division transmission equipment play in the data center?

1. Save fiber optics

One of the bandwidth costs of the data center is the cost of optical cable resources. The more optical fiber cores you rent, the more expensive it is. Wavelength division transmission equipment can be directly multiplexed and expanded on the original 2-core optical fiber, and the 2-core fiber can be transformed into 20-core, 40-core or even 80-core. . At present, most IDC customers already know that wavelength division can be used to solve the problem of insufficient optical cable resources.

2. Build a backbone network

Due to the large bandwidth of the upper backbone network of the data center, a single port exceeds 100G. If wavelength division equipment is used to build the network, a maximum bandwidth input of 80X100G/200G and a maximum of 16T can be achieved, which can meet the bandwidth output between cities, or between certain cities. Bandwidth entry and exit needs of some small countries.

3. Pure transparent transmission, low latency

Most of the customers in the data center have relatively high network requirements, such as bank customers, who have very high latency requirements. Since the wavelength division transmission equipment is purely transparent and does not perform any analysis and processing on the data, it only produces extremely low latency. When transmitting 100 kilometers, the delay is about 1 millisecond, so for high-end users in data centers, transmission equipment is a good choice.

4. Suitable for ultra-long distance transmission

Many data center services span multiple cities, and some even cross provinces and countries. The transmission distance is tens or hundreds of kilometers, or even thousands of kilometers. The longer the distance when laying optical cables, the higher the rental cost. At this time, the wave The transmission equipment can play its maximum value. The farthest ring network our transmission equipment has built overseas is more than 3,000 kilometers, surrounding the entire country and passing through more than 40 computer rooms. Currently, the equipment has been running stably for 6 For more than a year, users will need to upgrade and expand the wavelength division ports.
