Fiber Arrays Industry Chain Analysis
Fiber array (FA) is an optical device used to accurately locate bare optical fibers. Its core function is to achieve standardized arrangement of multiple optical fibers through a specific structure. The device consists of four major components: substrate, optical fiber, fixing glue and cover plate. The current mainstream fiber positioning technologies include drilling method, optical channel close arrangement method and groove positioning method. The groove positioning method can be subdivided into U-groove and V-groove solutions due to structural characteristics. In actual production, V-groove has become the industry's preferred technical path due to its excellent positioning reliability and convenient assembly operability.
In response to the vertical coupling requirements of active devices (such as laser/detector integration), the fiber array needs to be designed with a special structure: the optical fiber needs to protrude 0.15-0.35mm from the substrate surface to optimize the optical coupling efficiency, and the substrate end face is processed into a 45° bevel, which effectively avoids mechanical interference between the tool and the substrate during the grinding process.

Driving Factors
Global 5G Deployment and Massive Data Center Expansion
The global rollout of 5G networks and large-scale data center expansion are core drivers of growth in the fiber array unit (FAU) market. With the rapid development of applications such as artificial intelligence, cloud computing, and video streaming, data traffic is increasing exponentially, driving demand for higher-speed, higher-capacity transmission equipment.
As of June 2024, commercial 5G networks had been launched by 320 operators across 119 countries and regions, while 614 operators in 176 countries are investing in or planning to invest in 5G deployment. The total number of deployed 5G base stations globally reached 5.94 million—a 32.6% year-on-year increase. The demand for FAUs per base station is about three times higher than in the 4G era, especially in fronthaul networks where high-density fiber arrays are used in array-packaged 25G/50G CWDM optical modules.
At the same time, a recent McKinsey report predicts that global demand for data center capacity may grow at an annual rate of 19% to 22% between 2023 and 2030. The adoption of 800G optical modules is directly driving demand for high-channel-count FAUs, with single modules requiring 48-channel arrays.
Additionally, demand for cloud computing and AI computing power is increasing reliance on low-loss, high-density fiber arrays in hyperscale data centers. The penetration rate of FAUs in optical modules is rising rapidly, as data centers must upgrade their network architectures to handle the massive volume of data transmission and processing. FAUs, which integrate multi-core fiber arrays, meet the requirements for large bandwidth and multi-channel parallel transmission.
Accelerated FTTH Deployment Boosting FAU Demand
Globally, Fiber to the Home (FTTH) is becoming the mainstream fixed broadband access solution. As residential demand for ultra-HD video, cloud gaming, smart homes, and remote work continues to grow, governments and telecom operators are actively expanding FTTH infrastructure to meet gigabit-to-home or 10G-to-community broadband coverage goals.
To improve deployment efficiency and connection quality, telecom operators increasingly focus on the performance and reliability of fiber connectivity components. FAUs, which enable efficient connection of multi-core fibers, are widely used in optical splitters, optical distribution networks (ODNs), and optical access terminals. With features such as compact structure, high connection density, and easy installation, FAUs help improve network construction efficiency, reduce installation errors, and enhance signal stability.
Furthermore, FAUs improve modularity and ease of maintenance in access equipment, playing a crucial role in large-scale FTTH rollouts. High-density FAU products are especially advantageous in dense urban areas and complex building access scenarios. As FTTH continues to expand across emerging markets, developing countries, and rural broadband areas, the FAU market will experience both volume growth and structural upgrades.
CPO Technology Driving Demand for FAUs
CPO (Co-Packaged Optics) imposes higher requirements on the density, size, and stability of FAUs, driving their development toward higher integration and density. The rise of CPO technology is creating rigid demand for FAUs, especially in data center switches and high-performance computing devices, where its adoption rate is a key force behind FAU market growth.
As optical communication evolves from traditional modules to CPO technology, the entire industry chain is developing in tandem. FAUs, as a critical component in this ecosystem, are closely linked to CPO’s advancement. As CPO matures and sees broader adoption, upstream suppliers of fibers and FAUs are optimizing their products to meet CPO performance requirements—further increasing demand for FAUs.
Additionally, CPO is accelerating the development of the entire optical communication industry, strengthening collaboration across the value chain. Closer cooperation among optical module manufacturers, chip designers, and fiber connector suppliers is helping to drive the commercialization of CPO. This industrial synergy improves the supply and scalability of FAUs in CPO systems, enhancing their market prospects.
Key Development Trends
Growing Demand from Data Centers
With the explosive growth of the digital economy, data centers are expanding at an unprecedented rate. Countries around the world are competing to attract data center deployments, viewing them as foundational to future economic growth. Governments—from Singapore and Saudi Arabia to Ireland and Kenya—have introduced tax incentives, fast-track permitting, and dedicated infrastructure zones to attract foreign direct investment (FDI) in data center construction.
The global demand for cloud computing, artificial intelligence (AI), and high-performance computing (HPC) is placing immense pressure on data center bandwidth and latency. As a result, optical interconnects are increasingly replacing traditional copper links in short-reach and co-packaged environments.
Tech giants such as Meta, Google, Microsoft, and NVIDIA are investing heavily in co-packaged optics (CPO) and silicon photonics, both of which rely on precise and scalable fiber array components. These applications require compact, multi-channel, high-bandwidth connectors, driving a shift from discrete connectors to fiber array-based solutions that enhance performance while reducing power consumption and space requirements.
Rising Penetration of CPO
Faced with increasing demands for higher model performance and lower hardware costs, data centers urgently need architectures with higher density, lower latency, and reduced power consumption. This is accelerating the transition of computing clusters toward next-generation optoelectronic integration. Traditional pluggable optical modules are reaching their limits in terms of transmission efficiency, thermal management, and port density, making them less suitable for future HPC scenarios.
Co-packaged optics (CPO), which integrate optical engines directly with switch ASICs, significantly shorten the electrical signal path and deliver breakthroughs in bandwidth, latency, power, and package size—while maintaining compatibility with mainstream switch designs and avoiding major infrastructure overhauls. This "better performance at lower cost" evolution path is accelerating CPO's commercialization.
According to LightCounting, although pluggable modules will still dominate the market for the next five years, CPO is expected to capture nearly 30% of the 800G and 1.6T port market by 2027. As the technology matures and costs decline, CPO is likely to enter a positive cycle of performance-driven adoption and rapid penetration.
Increasing Channel Counts and Port Density
One of the most significant trends in the fiber array market is the rapid increase in channel counts. Historically, Fiber array units (FAUs) were designed with 2-, 4-, or 8-channel formats—sufficient for early optical transceivers. However, to meet the data throughput needs of 400G, 800G, and emerging 1.6T transceivers, the market is now shifting toward 16-, 32-, or even 64-channel fiber arrays.
This trend is driven by the need for greater bandwidth density per unit area and a desire to reduce the number of discrete interconnects. There are two main ways to increase optical module bandwidth: boost per-channel bit rates or increase the number of channels—either by adding more parallel fibers or using wavelength division multiplexing (WDM) such as CWDM or LWDM. High-channel-count arrays enable large-scale parallel optical links, which are critical for PSM modules, optical switches, and photonic integrated circuits (PICs).
As channel counts rise, so too does the demand for ultra-precision V-groove machining, submicron alignment, and advanced polishing techniques to ensure signal integrity across all fibers.
