Broadcom Inc. launches the Tomahawk 6 – Davisson (TH6-Davisson), the corporate’s third-generation co-packaged optics (CPO) Ethernet swap, delivering the bandwidth, effectivity, and reliability for next-generation AI networks. The TH6-Davisson gives advances in energy effectivity and visitors stability for increased optical interconnect efficiency required to scale-up and scale-out AI clusters.
The development towards CPOs in information facilities is to extend bandwidth and decrease vitality consumption. With the TH6-Davisson, Broadcom claims the business’s first 102.4 Tbits/s of optically enabled switching capability, doubling the bandwidth of any CPO swap obtainable as we speak. This units a brand new benchmark for data-center efficiency, Broadcom mentioned.
Designed for energy effectivity, the TH6-Davisson heterogeneously integrates TSMC Compact Common Photonic Engine (TSMC COUPE) technology-based optical engines with superior substrate-level multi-chip packaging. That is reported to dramatically cut back the necessity for sign conditioning and decrease hint loss and reflections, leading to a 70% discount in optical interconnect energy consumption. That is greater than 3.5× decrease than conventional pluggable optics, delivering a major enchancment in vitality effectivity for hyperscale and AI information facilities, Broadcom mentioned.
Along with energy effectivity, the TH6-Davisson Ethernet swap addresses hyperlink stability, which has turn out to be a important bottleneck as AI coaching jobs scale, the corporate added, with even minor interruptions inflicting losses in XPU and GPU utilization.
The TH6-Davisson solves this problem by instantly integrating optical engines onto a typical bundle with the Ethernet swap. The mixing eliminates most of the sources of producing and check variability inherent in pluggable transceivers, leading to considerably improved hyperlink flap efficiency and better cluster reliability, based on Broadcom.
As well as, working at 200 Gbits/s per channel, TH6-Davisson doubles the road price and general bandwidth of Broadcom’s second-generation TH5-Bailly CPO answer. It seamlessly interconnects with DR-based transceivers in addition to NPO and CPO optical interconnects working at 200 Gbits/s per channel, enabling connectivity with superior NICs, XPUs, and cloth switches.
The TH6-Davisson BCM78919 helps a scale-up cluster dimension of 512 XPUs and as much as 100,000+ XPUs in two-tier networks at 200 Gbits/s per hyperlink. Different options embody 16 × 6.4 Tbits/s Davisson DR optical engines and field-replaceable ELSFP laser modules.
Broadcom is now growing its fourth-generation CPO answer. The brand new platform will double per-channel bandwidth to 400 Gbits/s and ship increased ranges of vitality effectivity.
The TH6-Davisson BCM78919 is IEEE 802.3 compliant and interoperable with current 400G and 800G requirements. Broadcom is at present sampling the Ethernet swap to its early entry prospects and companions.
The publish Broadcom debuts 102.4-Tbits/s CPO Ethernet swap appeared first on EDN.
