company’s 800G/ 1.6T optical modules, along with its capacity expansion. We Goldman Sachs (Asia) L.L.C.

expect the shipment and value contribution from 800G+ optical modules continue

to increase in 2H26E, and expansion from scale-out to scale-up/ scale across from

2027E. Maintain Buy with new TP at Rmb633.

800G/ 1.6T optical module ramp up ahead: With improving optics chipset supply

and the company’s capacity expansion, we see shipment ramp up of 800G/ 1.6T

optical modules will drive QoQ revenue growth. Looking into 2H, we expect the

contribution from 1.6T modules and Silicon photonics products to continue to

increase, supported by continuous improvement of chipset supply and rising

demand from clients on 800G+ products. Despite near-term tight industry supply of

optics chips, we expect rising Silicon Photonics penetration and industry capacity

expansion to support shipment ahead.
