Fibronexa
Engineered for high-density environments and low-latency performance.
Fibronexa Communications Co., Ltd. is a professional optical transceiver manufacturer established in 2016, specializing in high-speed fiber optic communication solutions for global data center and telecom infrastructure markets. With a modern production facility covering approximately 3200㎡, Fibronexa has built a stable and efficient manufacturing system supported by advanced automation and precision assembly processes.
As a leading Optical Transceiver Manufacturer, we recognize that the shift from 100G to 400G and 800G is not just about speed, but about thermal efficiency, signal integrity (PAM4), and cost-per-bit reduction. Our 10-year industry expertise ensures that every QSFP28, QSFP56, and QSFP-DD module we produce adheres to strict MSA standards.
Leveraging China's world-class optical component ecosystem, we offer unbeatable lead times and cost efficiency. Our proximity to key semiconductor and laser diode suppliers allows us to bypass global logistics bottlenecks, ensuring 400G modules are delivered when your project needs them.
We strictly follow RoHS, CE, and FCC regulations. For our North American and European clients, we provide full TAA compliance support and localized technical documentation to ensure seamless integration into government and enterprise networks.
The industry is rapidly pivoting toward AI/ML workloads. This requires transceivers with lower latency and higher bandwidth. Fibronexa is already prototyping 800G OSFP/QSFP-DD800 solutions and LPO (Linear Drive Pluggable Optics) to meet future demands.
100G QSFP28 modules remain the backbone of most enterprise data centers. With variations like LR4 (Long Range) reaching 10km and ZR4 reaching up to 80km, these modules utilize four 25Gbps lanes. Our factory ensures signal integrity over single-mode (SMF) and multi-mode fiber (MMF) through rigorous DDM (Digital Diagnostic Monitoring) calibration.
Transitioning to 200G introduced PAM4 (Pulse Amplitude Modulation). Unlike NRZ used in 100G, PAM4 doubles the data rate by carrying two bits per clock cycle. Our 200GBASE-SR4 modules are optimized for AI clusters where density and power consumption are critical factors.
400G QSFP-DD (Double Density) is the current gold standard for Hyperscale Data Centers. With 8 lanes of 50G PAM4, these modules demand advanced cooling designs. Fibronexa's 400G DR4 and FR4 modules feature low-power DSPs and optimized laser packaging to maintain performance even at high operational temperatures.
Expert insights for procurement managers and network architects.
Extended solutions for short-range and long-haul networking.
At Fibronexa, we understand the complexities of global procurement. With over 6 years of export experience and a footprint in North America, Europe, and Southeast Asia, we don't just ship products; we provide end-to-end connectivity assurance.
Our 100G, 200G, and 400G optical modules are designed for scalability. Whether you are upgrading a legacy 10G network or building a greenfield 400G AI data center, our manufacturing facility provides the volume, quality, and technical expertise required for modern digital transformation.
