Fujitsu Limited
6702.TMEDIUMOptical Transport (OTN) — JP equivalent of $NOK · Weight: 7%· Data as of 2026-05-14
Investment Thesis
Direct JP equivalent of Nokia ($NOK) in the X post — Fujitsu's 1FINITY Ultra Optical System delivers 1.2 Tbps per wavelength with upgrade path to 1.6 Tbps, using liquid cooling + AI/ML automation. P300 800G ZR/ZR+ coherent pluggable transceiver covers hyperscale data center interconnect. Like Nokia's PSE-6s, Fujitsu's 1.2 Tbps coherent capability is one of the few non-Cisco/non-Nokia/non-Infinera solutions globally. Cheaper valuation than Nokia (Fujitsu PE 18.9 vs Nokia ~30) despite similar OTN positioning. FY2026 net income +104.5%, revenue ¥3.50T. The 'forgotten one' of Japanese photonics — market still sees Fujitsu as an IT services company.
Risk
OTN is a small fraction of Fujitsu's total revenue (also IT services, Uvance / Modernization). Most analyst coverage focuses on services growth, not photonics. If hyperscale buyers consolidate around Nokia/Cisco/Infinera, Fujitsu's photonics window narrows. PE 19x is not deep value — but for the OTN exposure alone, the multiple is reasonable.
Monitoring Trigger
If 1FINITY Ultra wins a named hyperscale design (NVIDIA / Meta / Microsoft / Google), upgrade. If Fujitsu announces an OTN-business carve-out or IPO, MASSIVE value crystallization. If Nokia (post-Infinera) or Cisco wins long-term contracts that include Tier-2/Tier-3 hyperscale buyers, photonics window narrows.
