We are now in an important strategic period of the vigorous development of the new generation of information technology, and the data center has entered a new stage of rapid development. At present and in the coming future, cloud computing, big data, industrial Internet, AR/VR and other new generation technologies are booming, and the demand for data processing is increasing sharply, which also presents the challenge for data centers to be denser, faster and more environmentally friendly. Driven by bandwidth, market demand and cost, the data rate of the optical transceiver in data center is constantly increasing and the power consumption is constantly decreasing.
Optical interconnection for data centers includes optical transmission and optical exchange. In the optical transmission part, which is the transmission of optical signals between switches and between servers and switches, GrenTech provides a series of optical transceivers with stable performance and high reliability.
The data center architecture has been transferred from the traditional 3-tier architecture to the 2-tier flat architecture. In the data center adopting spine-leaf two-tier architecture, single-mode transmission is used between leaf and spine switches, and the transmission distance is greater than 500m. Multi-mode transmission is used between ToR - Leaf and Spine switches, the transmission distance is greater than 30m. The server is connected to the TOR switch using AOC/DAC and the transmission distance is about 3 to 5 meters.
The following diagram shows an example of a 100G data center, where GrenTech provides optical transceiver between different levels
With the advent of 40/100G network era, the traditional LC cabling can no longer meet the demand of high density and high transmission rate of data center. MPO/MTP wiring can use 1 MPO/MTP connector instead of 12 or 24 LC connectors. MTP/MPO connection standard is miniaturized high density optical fiber connector standard, a single connector is equipped with multi-core ribbon fiber, which has high density, stable and reliable connection. By using MTP/MPO high density distribution system to complete the assembly and test of high density optical fiber connector and ribbon optical cable in factory, it is available for plug and play with equipment in the field to support rapid deployment in the user's data center. It is an ideal solution for the growing demand for high-capacity wiring in the data center.
GrenTech has a complete solution of MTP/MPO distribution system, including trunk optical cable, MTP/MPO box, optical fiber distribution box and various types of patch cords.
