Physical layer circuit

Abstract

Embodiments of the invention provide a physical layer circuit. The physical layer circuit comprises a first circuit and M second circuits. The first circuit is used for processing a first data block stream to obtain a first data stream, and distributing the first data stream to N1 second circuits in the M second circuits. The N1 second circuits are used for processing the received first data stream to obtain N1 first code streams. The N1 second circuits are in one-to-one correspondence with the N1 first code streams. According to the technical scheme provided by the embodiment of the invention, the requirements for complex bandwidth configuration can be met, and the application scene is expanded.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a physical layer circuit. Background technique [0002] At present, the traffic of the telecommunications backbone network is increasing rapidly at a rate of 50% to 80% every year. The 802.3 working group of the Institute of Electrical and Electronics Engineers (abbreviation: IEEE, English: institute of electrical and electronics engineers) started to collect bandwidth development after the publication of the 100 Gigabit Ethernet (English: gigabit ethernet, abbreviation: GE) standard since early 2011. need. It is predicted that network traffic in 2015 may reach ten times that in 2010. Future Ethernet interfaces may have two types of Ethernet interfaces, 400GE and 1 Terabit Ethernet (English: terabit ethernet, TE for short). The above two Ethernet interfaces may be widely used in 2015 and 2020, respectively. [0003] The rate of current routers is generally 200G, 480G or...
