Product Introduction

CTC8180 (TsingMa.MX) is the core network switching chip launched by Centec for the cloud era. CTC8180 will become the connection hub of cloud-network convergence, integrating all the characteristics of enterprise network, bearer network, and access network, and providing infinite possibilities for the future through mortise and tenon programmable technology.

The chip supports 2.4T I/O bandwidth, provides full-rate port capabilities from 1000M to 400G, and has the following leading service features:

• Intelligent network visualization technology

The chip uses hardware to learn, record, and report the chip and traffic status, providing more accurate and detailed visual information for network applications, and greatly reducing the load of CPU traffic analysis, supporting the full implementation of intelligent technology.

• Deterministic network technology

The chip can provide maximum 800G FlexE switching capabilities, support 50G/100G/200G/400G FlexE interfaces, and flexible FlexE group binding. The chip supports SCL L1 crossover, FlexE OAM, and PTP functions, as well as the superimposed protection functions of services and FlexE, as well as deterministic ultra-low latency, to meet latency-sensitive network requirements.
