Established in 2012 in Hong Kong as a high-tech communication enterprise, Kocent Optec Limited has emerged as one of China's premier fiber optic termination product manufacturers and solution providers. With over 13 years of industry experience, we specialize in both passive and active optical components essential for modern telecommunication networks, enterprise infrastructures, and massive-scale data centers.
By leveraging our extensive experience and excellent production capacity gained over the years, we magnify the outcome for our valuable customers. This collaborative approach expands their core competencies and helps them outperform competitors in the rapidly evolving 100G and 400G markets.
The 100G QSFP28 PSM4 (Parallel Single Mode 4-lane) standard has reached a peak level of maturity. It remains the preferred choice for hyperscale data centers requiring reach up to 2km, offering a perfect balance between the low cost of SR4 (Short Range) and the long-distance capabilities of CWDM4.
Utilizing 4 lanes of 25Gbps NRZ modulation over single-mode fiber with MTP/MPO connectors, PSM4 simplifies the optical architecture. It avoids the complexity of wavelength multiplexing, making it highly reliable for massive East-West traffic within data center spines.
Global procurement for 100G PSM4 has transitioned from early adoption to large-scale industrial maintenance and infrastructure expansion. Industries like AI-driven cloud computing, high-frequency trading, and 5G backhaul rely on PSM4 for stable, low-latency data transmission.
As global data traffic grows, the industry is seeing a trend toward higher density. This is where China 100g Psm4 manufacturers excel. By integrating MTP/MPO-12 connectors with single-mode fiber, PSM4 allows for seamless migration paths to 400G and 800G through "breakout" configurations.
Kocent Optec operates state-of-the-art production facilities in China, following strict international fiber optic industry standards. Our commitment to quality is anchored in mature scientific methods and rigorous testing protocols.

KCO Fiber provides a consultative approach to engineering custom optical solutions. Whether you need specific labels, customized optical designs, or specialized mechanical enclosures, we deliver solutions that match your technical requirements.
Our transceivers (SFP, QSFP28, QSFP-DD) are compatible with leading brands such as Cisco, Huawei, ZTE, H3C, Juniper, HP, Dell, and Netgear. We empower our partners to leverage their strengths while we handle the complexities of precision manufacturing.
Tactical CPRI, MTP/MPO patch cords in any length, fiber type (OM3, OM4, OS2), and color.
ODM services for fiber optic terminal boxes, distribution frames, and splice closures based on your drawings.
Custom firmware coding for transceiver compatibility and specialized DDM/DOM monitoring features.
China hosts the world's most integrated supply chain for optical communications. From laser chip packaging to precision plastic molding for connectors, sourcing locally ensures reduced lead times and competitive pricing.
Factories like Kocent Optec invest in high-end testing gear including Keysight/Anritsu bit error rate testers (BERT) and high-speed oscilloscopes to ensure every 100G PSM4 module meets the IEEE 802.3bm standard.
Unlike many Western distributors, Chinese manufacturers offer deep customization even for medium-sized batches, allowing for specific cable jackets (LSZH/OFNP) or unique breakout lengths.
