Engineered for high-density networking environments and reliable long-reach performance.
In the current telecommunications era, the 100G QSFP28 LR4 optical transceiver has become the fundamental building block for long-distance data transmission. Unlike SR4 (Short Reach), the LR4 technology utilizes LAN-WDM multiplexing over four wavelengths in the 1310nm window, allowing for data transmission up to 10km over single-mode fiber (SMF). Globally, as cloud service providers (Hyperscalers) like AWS, Google, and Microsoft continue to expand their hyperscale data centers, the demand for 100G LR4 remains robust due to its perfect balance between cost, power consumption, and reach.
The industrial rollout of 5G NR networks has significantly shifted procurement trends. 100G LR4 modules are critical in the "middle-haul" and "backhaul" segments of 5G infrastructure. Telecom operators worldwide are upgrading their metro-area networks to handle the massive influx of mobile data. The reliability of 100G LR4 ensures that packet loss is minimized over 10km spans, which is the sweet spot for urban fiber ring architectures. Kocent Optec Limited serves this sector by providing carrier-grade modules that meet stringent outdoor temperature requirements.
While 400G and 800G are entering the core of massive data centers, the 100G LR4 technology is evolving through Silicon Photonics and single-lambda (100G LR1) innovations. However, the traditional 4x25G LR4 standard remains the most widely compatible and reliable solution for existing legacy hardware. We observe a trend toward "green" transceivers—modules with reduced power consumption (under 3.5W)—which directly impacts the operational expenditure (OPEX) of large-scale server farms.
Established in 2012 in Hong Kong, Kocent Optec Limited has grown into a high-tech communication enterprise and one of China's leading fiber optic termination product manufacturers. Our mission is to bridge the gap between complex network demands and efficient hardware solutions.
By leveraging our extensive experience and excellent production capacity, we magnify the outcome for our valuable customers. We define ourselves as your partner in fiber optic connection solutions, believing that our differentiators are your perceived advantages. With over 13 years of expertise, we follow strict industry standards (ISO, Telcordia) to ensure 100% of our products are inspected before shipment.
A glimpse into our high-standard production environment where precision meets technology.
Our SFP and QSFP production lines are equipped with state-of-the-art Agilent and Anritsu error-rate testers. Every 100G LR4 module undergoes rigorous temperature cycling and aging tests to ensure long-term stability in commercial environments. Our passive product lines (MTP/MPO) utilize 3D interferometers to guarantee fiber end-face geometry, meeting the ultra-low insertion loss requirements of modern data centers.
KCO Fiber provides transceivers compatible with over 50 global brands including Cisco, Huawei, ZTE, Juniper, HP, Dell, and Arista. Our software engineers can write custom EEPROM code to ensure seamless integration into any vendor's ecosystem without triggering "unsupported transceiver" warnings.
We provide full-stack ODM services: Optical design, PCB layout, mechanical housing customization, and firmware development. Whether you need a specific wavelength, a ruggedized industrial housing, or a specific thermal dissipation profile, our R&D team can deliver.
Beyond transceivers, we customize Tactical CPRI Patch Cords and MTP/MPO breakout cables. We can specify any fiber type (G.652D, G.657A2, OM3/OM4/OM5), any length, and even custom jacket colors and branding labels for your specific projects.
Global enterprises face unique challenges when sourcing 100G LR4 products. In North America and Europe, the primary demand comes from Enterprise Data Centers (EDC) migrating from 10G/40G to 100G. These clients prioritize reliability and compliance. In contrast, in emerging markets like Southeast Asia and South America, the focus is on ISP infrastructure expansion and FTTH backhaul, where cost-performance ratios are the deciding factor.
Our localized application scenarios include:
As a leading China-based factory, Kocent Optec Limited offers the distinct advantage of a complete supply chain. We source raw materials (TOSA/ROSA) at scale and maintain high-efficiency assembly lines, allowing us to offer prices 30-50% lower than traditional "Original" brand transceivers without sacrificing quality.
Completing your network infrastructure with professional-grade components.
