Explore our core optical components, custom hardware solutions, and production equipment optimized for high-bandwidth networks.
The surge in global internet traffic, accelerated by generative AI, high-performance computing (HPC), and 5G network expansion, has placed unprecedented demands on data center architectures. In this context, 100G QSFP (specifically QSFP28) has emerged as the definitive workhorse of modern optical networking, delivering the optimal balance of power efficiency, thermal performance, and port density.
Historically, legacy 40G systems struggled to keep pace with bandwidth demands, while emerging 400G and 800G systems remain cost-prohibitive for broad enterprise adoption. 100G QSFP28 modules bridge this gap by utilizing four independent channels of 25Gbps signals (using NRZ modulation) or single-lane lambda structures (using PAM4). As global supply chains mature, optical transceivers have transitioned from high-cost specialty units to highly optimized, scalable interconnects that power hyperscale data centers, enterprise server farms, and metropolitan transport systems.
Established in 2012 in Hong Kong as a high-tech communication enterprise, Kocent Optec Limited is one of China's leading fiber optic termination product manufacturers and solution providers.

Whether configuring multi-vendor switches, scaling metro backhauls, or providing clean connectivity with our custom clean-room instrumentation, Kocent Optec ensures every transceiver and component performs to standard under demanding enterprise conditions.
Choosing the right transceiver architecture is critical to matching infrastructure capabilities with budget requirements. Below is the technical breakdown of the 100G QSFP28 standards and the roadmap toward higher bandwidth configurations.
Designed for short-reach applications, utilizing multimode fiber (OM3/OM4/OM5) with MPO/MTP connectors. Operates at 850nm over 4 independent channels of 25Gbps. Maximum transmission distance is 100m over OM4. Ideal for top-of-rack (ToR) switch links.
Designed for long-reach applications over single-mode fiber (SMF) using LC connectors. Utilizes WDM (Wavelength Division Multiplexing) to combine 4 channels onto a single fiber pair, spanning up to 10km. Crucial for campus connections and backbone routing.
QSFP28 ER4 supports extended distances up to 40km over SMF using SOA (Semiconductor Optical Amplifiers). CWDM4 offers a cost-effective 2km intermediate reach, avoiding expensive single-mode fiber infrastructure over medium distances.
Different networking environments present unique requirements for environmental resilience, power limitations, and fiber termination configurations.
High-performance computing data centers require massive scale and low latency. Utilizing 100G QSFP28 transceivers alongside high-density MPO/MTP patch cables ensures clean data transmission with low packet loss. This design minimizes cabling clutter, optimizes chassis airflow, and lowers power usage to keep cooling requirements manageable.
Modern telecommunications networks demand transceivers capable of withstanding extreme environmental changes. Our temperature-hardened optical transceivers operate reliably within industrial ranges (-40°C to 85°C), enabling steady data transport from remote antenna units (RRUs) to baseband processing hubs.
For corporate headquarters and university campus networks, transitioning from 10G/40G backbones to 100G is straightforward. By deploying QSFP28 LR4 modules over existing single-mode fiber and matching them with reliable media converters, organizations can increase network capacity while avoiding expensive fiber updates.
