1、 Data Center Overview

With the development of the communication industry, the construction of modular data centers has become a common trend. With years of experience, Changcheng provides innovative modular data center optical series products, including optical distribution frames, modules, pre terminated jumpers, and other products, which have high density and scalability, and are suitable for the smooth upgrading of future large data centers of 40G/100G/400G.

With the arrival of the big data era, the development of internet data centers has improved the overall computing power level and ushered in large-scale construction. The internal data transmission rate of internet data centers has also moved from the initial gigabit and gigabit networks to the stage of large-scale deployment of "25G access+100G interconnection". In the era of "100G access+400G interconnection", data centers have also begun to deploy and pave the way for future 800G links.

2、 Application of OM3/OM4/OM5 Fiber Optics

At present, the average distance between the Internet data center TOR and the leaf switch is about 45 meters, and the distance between the leaf and ridge switch is within 200 meters. The OM3/OM4 fiber optic system can be used for the link of the TOR leaf switch, while the OM4/OM5/OS2 fiber optic system is recommended for the link of the leaf ridge switch.

2.1 The average distance between TOR and leaf switches is about 45 meters. OM3/OM4 fiber optic system can be used in the link of TOR leaf switch

2.2 It is recommended to use OM4/OM5/OS2 fiber optic systems in the link of leaf ridge switches with a distance of less than 200 meters.

What is the optical module for

Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The optical module is also called a fiber optic transceiver, which is mainly used for photoelectric conversion of signals. At the transmitting end, the electrical signal of the device is converted into an optical signal, and at the receiving end, the optical signal is restored to an electrical signal. The optical module is composed of a laser at the transmitting end, a detector at the receiving end, and electronic devices for data encoding/decoding.

What is the principle of optical communication?

The principle of optical fiber communication is: at the sending end, the transmitted information (such as voice) must first be converted into an electrical signal, and then modulated onto the laser beam emitted by the laser, so that the intensity of the light changes with the amplitude (frequency) of the electrical signal. And send it out through the optical fiber; at the receiving end, the detector converts the optical signal into an electrical signal after receiving it, and restores the original information after demodulation.
