Due to the extensive use of optical transceivers in both scale-up and scale-out network, this 384-GPU cluster is very power hungry. We estimate that
At the 2025 Huawei Cloud Ecosystem Conference, the CloudMatrix384 (CM384) supernode once again attracted widespread attention
Huawei is promoting its Supernode 384, a high-performance AI computing system using Ascend processors, as a competitor to Nvidia''s NVL72
Use the command display transceiver to view the optical module information of all optical ports, and use the command display transceiver interface interface-type interface-number to view the
Exclusive channel loss resistance and contamination & looseness detection improve module reliability by 10x. Huawei provides a full series of pluggable optical modules. A wide variety of modules give
The Ascend 384 supernode uses an all-optical interconnect architecture (3,168 optical fibers + 6,912 400G optical modules), replacing traditional copper cables to achieve long-distance, high
A switch must use optical or copper modules that have been certified for use on Huawei switches. Non-certified optical or copper modules cannot ensure transmission reliability and may affect service
Therefore, when using such optical modules, select optical fibers of an appropriate length to ensure that the actual receive power is smaller than the overload power. If the optical fibers connected to a long
Use optical modules with a longer transmission distance on the two ports. When connecting switches through optical ports, pay attention to the following points:
The ratio of next-generation AI chips (such as the B300) to optical modules will increase from 1:3 (H100) to 1:4.5 or even 1:8 (specific ASIC
Evolving towards the 2030 optical communications network system and architecture is a key issue facing the optical communications industry and requires viable technical options for building future
Huawei offers a comprehensive portfolio of pluggable StarryLink optical modules for data center networks, with various models providing flexible plug-and-play solutions tailored to diverse interface
Use an optical power meter to measure the receive power of the port. Form a loop on the port using an optical fiber, and check whether the port can go Up (if optical modules with a long transmission
Huawei''s CloudMatrix 384 Supernode delivers 300 petaflops—beating Nvidia NVL72—via 384 Ascend 910C chips and optical
This document provides an overall description of the CE12800 series switches hardware, helping you obtain detailed information about each chassis, power module, fan module, card, cable, and
CloudMatrix 384 supernode is the answer given by Huawei Cloud. What Makes CM384 Different? CloudMatrix 384 super-node uses 6912 x 400G
Analysts see the supernode trend as a tailwind for domestic suppliers of optical interconnects and liquid-cooling components. As supernode penetration grows, demand should lift
For details about the optical modules supported by optical ports on switches, see "Appearance and Structure" of a specific switch model in the Hardware Description. The following figure shows the
In this case, how to use efficiently use meshes to interconnect the chips within large AI systems. Eyeing so-called SuperNodes – singular
Optical Modules in Intelligent Computing Scenarios In the AI era, Huawei provides a full range of GE to 800GE optical modules, featuring three major capabilities: Spanning (ultra-long transmission), Stable
CloudMatrix 384 super-node uses 6912 x 400G OSFP silicon photonic (SiPh) Linear Drive Pluggable Optics (LPO) optical modules and 3168
Huawei''s latest AI innovation, the Supernode 384, showcases a significant leap in AI computing, challenging Nvidia''s market leadership amid US-China tech tensions.
At Huawei, we have been developing a more unified approach to infrastructure design with UB-Mesh —reframing the data center as a tightly integrated system rather than a collection of loosely
Huawei''s approach introduces what it calls "hundred-nanosecond-level" fault detection and protection switching mechanisms, combined with
On an optical network, a sender needs to convert electrical signals into optical signals before sending them to a receiver, and the receiver needs to convert received optical signals into electrical signals.
If different optical modules are used at the two ends, the communication may fail. Huawei optical modules are recommended. The optical modules from other vendors may cause faults on the USG
