Cloud Tranceiver The Sustainable Development

Cloud Tranceiver With the continuous development of trends such as cloud computing, industrial networking and software definition networks, accelerating and driving demand for unlimited bandwidth, Cloud Tranceiver technology innovation must extend support for 50G, 100G, 400G ports, and TB interfaces to maximize port density without increasing unit bit costs and power consumption. Standardized line rates are critical to meeting the evolving next generation bandwidth requirements. In the Optical Interconnection Forum (OIF) and the Institute of Electrical and Electronic Engineers (IEEE), Xilinx plays a leading role in the work of 56G PAM4 standardization. The 56G PAM4 transceiver technology developed by Ling Si has broken through the physical limitations of Cloud Tranceiver traditional transmission of data by line rate, and solved the problems of insertion loss and crosstalk. The technology supports chips and chips, modules, straight cables or backplane applications such as copper wire and optical interconnection, to support the implementation of more than TB-level line cards, 400G or even TB rack back-panel system design Next generation.

Transceiver is a signal conversion device, usually refers to a fiber transceiver. The emergence of fiber-optic transceiver, the twisted pair of electrical signals and optical signals to each other to ensure the smooth transmission of packets between the two networks, while it will network Cloud Tranceiver transmission distance from the limit of 100 meters to 100 km (Single-mode fiber). ”

Because of the use of different media, transceiver can transmit the distance is not the same, Multimode transceiver general transmission distance between 2 kilometers to 5 kilometers, and the single mode transceiver coverage can range from 20 km to 120 kilometers. It is necessary to point out that the transmission power, receiver sensitivity and wavelength of the fiber transmitter are different depending on the Cloud Tranceiver transmitting distance. The receiving sensitivity of 5 km fiber transceiver is -30, using 1310nm wavelength, while the receiving sensitivity of 120 km fiber transceiver is 18-38d, using 1550nm wavelength.

According to the structure, can be divided into desktop (independent) fiber transceiver and rack-type optical transceiver.

Desktop fiber transceiver Suitable for a single user, such as a single switch in the corridor to meet the upper allied. The rack-type optical transceiver is suitable for multi-user aggregation, such as the central room of the cell must meet the upper allied of all the switches in the community, the use of the rack to facilitate the implementation of all modular optical fiber transceiver Unified management and unified power supply.
