Lensed Fibre
Metallized Opitcal Fibre and Component
Deliver cost‑-effective solutions for key optical‑communication sectors.
Data Center
Data‑center interconnection underpins AI compute clusters and cloud computing. For new‑gen high‑density flat data‑center architectures, we have overcome transmission challenges from exponential bandwidth growth.
PON Access
PON, the mainstream broadband‑access technology, powers global operators’ gigabit services and supports scenarios such as government‑enterprise private networks, 5G, IoT and industrial automation.
Metro&DCI
Supports metro & data‑center interconnection for cross‑regional computing scheduling, assisting operators and cloud providers in building nationwide all‑optical transmission networks.
5G Wireless Transport
As the foundation of the digital economy, 5G bearer networks meet stringent bandwidth, latency and clock‑synchronization requirements for broadband communications, low‑latency services and massive‑terminal access.
Cabling Fiber‑Optic Connectors
Fiber‑optic connectors are fundamental optical‑communication components, enabling fiber‑to‑fiber and fiber‑to‑chip interconnection. Products serve multiple industries including telecom, aerospace, energy, medical and automotive.
Serving diverse optical‑communication applications, our products sell well across China, North America, Europe and Southeast Asia, earning global customer trust.
