Kocent Optec Limited, established in 2012 in Hong Kong as a premier hi-tech communication enterprise, has risen to become one of China's leading fiber optic termination product manufacturers and solution providers. Our journey began with a vision to bridge the gap in high-speed data transmission, and today, we stand at the forefront of the 100G and 400G revolution.
We are dedicated to the comprehensive development and manufacturing of fiber optic communication products. Our portfolio spans from passive components to advanced active categories, catering to telecommunication networks, enterprise infrastructures, and massive cloud data centers. With over 13 years of specialized experience, we have mastered the scientific methods required to deliver excellence consistently.
By leveraging our extensive production capacity and technical expertise, we empower our global customers to expand their core competencies. We don't just sell products; we define ourselves as your strategic partner in fiber optic connection solutions. Our commitment to 100% testing and inspection ensures that every 100G QSFP28 SR4 module and MTP/MPO cable leaving our facility meets the highest international standards.
The 100G QSFP28 SR4 remains the workhorse of modern data centers. Despite the emergence of 400G and 800G, 100G modules currently hold the largest market share in terms of volume due to their optimized cost-to-performance ratio for short-reach (up to 100m) interconnects.
The surge in Artificial Intelligence (AI) and Machine Learning (ML) workloads requires massive east-west traffic bandwidth. Global giants in North America, Europe, and Asia are procuring 100G SR4 modules by the thousands to build low-latency fabric networks.
Localized application scenarios such as 5G edge nodes and smart cities are driving the demand for 100G. These environments require reliable, compact, and low-power consumption transceivers like the QSFP28 SR4 to handle real-time data processing.
In the current industrial landscape, the 100G QSFP28 SR4 (Short Range 4-channel) is the preferred choice for connecting switches to servers and switches to switches within the same rack or adjacent racks. Utilizing 850nm VCSEL technology and MPO-12 connectivity, it provides a seamless migration path from 10G and 40G architectures. As a professional China manufacturer, KCO Fiber stays ahead of these trends by integrating the latest silicon photonics and chip designs into our production lines.

Our factory operates under strict ISO standards. The SFP/QSFP production line is equipped with automated aging test systems and high-precision spectral analyzers to guarantee that every 100G QSFP28 SR4 transceiver offers maximum reliability. Meanwhile, our MTP/MPO production line focuses on low insertion loss and high return loss performance, essential for the OM3/OM4/OM5 fiber links that SR4 transceivers utilize.
Our modules are engineered to be 100% compatible with major brands including Cisco, Huawei, ZTE, H3C, Juniper, HP, Dell, Netgear, and Arista. We utilize specialized coding and testing to ensure seamless plug-and-play operation.
From custom optical design and PCB layout to specialized firmware development, we provide tailored solutions for unique network requirements. This includes specific labels, custom cable lengths, and unique housing designs.
We support our partners with complete branding solutions. Whether you need private labeling (OEM) or full product development (ODM), KCO Fiber is equipped to scale with your business growth.
Global procurement teams often face challenges regarding supply chain stability and cost control. As a direct China factory, KCO Fiber offers several distinct advantages:
At Kocent Optec Limited, quality is the cornerstone of our authority. Each 100G QSFP28 SR4 transceiver undergoes a rigorous multi-stage testing process. First, the Optical Component Testing ensures the integrity of the VCSEL lasers and PIN photodiode arrays. This is followed by Automated PCB Verification using high-speed SMT machines and AOI inspection.
The final and most crucial stage is the Real-Switch Interoperability Test. We maintain a lab with hundreds of different switch models from Cisco to MikroTik. Every module is plugged into its intended environment to verify bit error rates (BER), eye diagrams, and DDM (Digital Diagnostic Monitoring) accuracy. This "Real-World" testing protocol is why KCO Fiber is trusted by telecom operators and enterprise IT managers worldwide.
The industry is currently witnessing a massive shift towards Hyperscale Data Center architectures. While 100G QSFP28 SR4 is the current standard for 100m multimode links, we are seeing increasing interest in 100G Single-Lambda technologies and 200G/400G SR4 evolutions. KCO Fiber is already producing 200G QSFP-DD and QSFP56 solutions to meet this rising tide.
Another major trend is the Greening of Data Centers. Power consumption per gigabit is a critical metric. Our latest 100G modules are designed with optimized ICs that reduce power consumption to less than 2.5W, helping operators reduce cooling costs and improve their PUE (Power Usage Effectiveness) ratings.
