TSMC's COUPE via SoIC-X enables 3D PIC/EIC vertical stacking, cutting transmission distance. Against laser heat sensitivity, ELS/RLS (External Laser Source) architecture emerged, relocating heat from chassis. This "full-stack" strategy creates a "de-packaging" survival crisis for traditional modu...

Google pushes OCS & CPO tech for power saving in millions of TPU clusters. Broadcom's Bailly platform, the first commercial 51.2T/102.4T CPO system, cuts 70% power. This revolution vertically compresses supply chain, making silicon photonics dominant solution post-2028.

Taiwanese firms shifted value in 1.6T era. E-Da Technology deeply partnered with Marvell for co-dev; LuxNet Corp. monopolized US CSP access via 6,912+ core panels; OptiWorks Inc. leveraged global OEM resilience/yield to become Broadcom's key production hub.

The global 1.6T market is defined by three giants: Marvell levies a "brain tax" with its 3nm DSP chips; Lumentum defines mass production pace with EML laser chip capacity (40% expansion); and Coherent, leveraging vertically integrated indium phosphide materials and modules, secured historic major...

As single-channel rates approach 224Gbps (1.6T spec), electrical signal loss on copper wires hits physical limits. Over 1 meter, copper signals severely distort and overheat, forcing data centers to fully shift from copper to optical. This isn't a cost choice, but a physical necessity to break th...

Kingstate (3044) avoided AI's high capex, efficiently dominating 40% general server and 55% DRAM module markets where peers exited, achieving AI-like profits. Zhen Ding (4958) raised $400M for carrier boards, leveraging Hon Hai's EMS for full GB200 system supply chain penetration. These two giant...
