At this top-tier global communication industry event, four leading Chinese optical communication companies—Hengtong, YOFC, FiberHome, and ZTT—gathered together to showcase the latest innovations and industrialization capabilities of Chinese enterprises in the optical communication field, focusing on cutting-edge areas such as hollow-core fiber, AI computing infrastructure, marine communications, and FTTx all-optical networks. From core materials to system solutions, from land to sea, from transmission media to intelligent operations, the Chinese optical communication industry presented a collective front, sending a clear signal to the global industry: in an era of deep integration between AI and communications, China's strength is becoming a key engine reshaping global digital infrastructure.

01 Breakthroughs in Hollow-Core Fiber Technology, Ushering in a New Era of "Near-Light-Speed" Transmission
Against the backdrop of extreme demands from AI large models for data transmission latency and bandwidth, hollow-core fiber, with its disruptive technology using air as the transmission medium, has become the core path to breaking through the physical limits of traditional silica fiber. At this year's MWC, the collective breakthroughs achieved by Chinese optical communication companies in the field of hollow-core fiber became a focal point of attention.

Hengtong Optic-Electric also achieved significant breakthroughs in the field of hollow-core fiber: its hollow-core anti-resonant fiber reduces transmission latency by 33% and has a bandwidth potential exceeding 200THz. Hengtong has taken the lead in China to achieve the commercial deployment of the first hollow-core fiber financial dedicated line and has successfully won bids for domestic DCI commercial projects, while also initiating trials in multiple overseas locations. Min Yue, Director of Hengtong's Optical Network Business Unit, stated at the exhibition site that hollow-core fiber can increase transmission speed by 45%, and after applying this cutting-edge technology to access networks, home and industrial users will experience microsecond-level ultra-low latency.

YOFC officially launched its hollow-core fiber brand HollowBand^® during the conference and announced that its anti-resonant hollow-core fiber has achieved the world's lowest attenuation of 0.04dB/km, reducing latency by 31% and increasing transmission speed by 47% compared to traditional solid-core fiber. Even more remarkably, YOFC has achieved a single hollow-core fiber preform drawing length of 91.2 kilometers and has deployed over 10 commercial and pilot projects globally, including the Guangdong-Hong Kong 100km project—the world's longest hollow-core fiber commercial project. YOFC simultaneously launched the INFINITE-2030 Plan, aiming to promote the deployment of over 50 commercial projects globally and the formulation of international standards.

FiberHome Telecommunications made a major announcement at the conference, unveiling its new generation improved double-nested structure ultra-low-loss hollow-core fiber, with a minimum attenuation value of 0.06dB/km @1550nm and a transmission latency reduction of 31% compared to traditional solid-core fiber. FiberHome has overcome industry challenges such as non-compliant PMD indicators and loss fluctuations. The total loss over 10km is only 1.2dB (including 0.6dB connector loss), and the additional attenuation after loosely winding 100 turns at a 50mm radius is ≤0.1dB, demonstrating superior environmental adaptability and bending resistance. Currently, FiberHome possesses full-process industrialization capabilities from raw materials and equipment platforms to batch manufacturing processes, and has obtained authoritative certification from China Telecommunication Technology Labs (CTTL).
