Establish in 2012 in Hong Kong as a hi-tech communication enterprise, Kocent Optec Limited is one of China's leading fiber optic termination product manufacturers and solution providers. We are dedicated to developing and manufacturing fiber optic communication products ranging from passive to active categories for modern telecommunication networks, enterprise infrastructures, and next-generation cloud data centers.
By leveraging our extensive engineering experience and deep production capacity gained over the years, we magnify the outcome for our valuable customers. This strategic dedication ultimately expands their core competencies and helps them outperform global competitors. At Kocent Optec, we place heavy emphasis on close customer collaboration, defining ourselves not just as a supplier, but as your valuable partner in high-performance fiber optic connection solutions.
As Artificial Intelligence (AI) workloads, Large Language Models (LLMs), and cloud computing networks demand massive computing power, data center physical infrastructures are undergoing an unprecedented shift. The transition from 400G interfaces to 800G transceivers has become essential to support high-throughput, low-latency computing requirements. The industry is standardizing around form factors like the 800G QSFP-DD800 and OSFP (Octal Small Form Factor Pluggable) to maximize data port density per rack unit.
Global demand is driven by the scaling of AI training clusters (utilizing architectures like NVIDIA Hopper and Blackwell, AMD Instinct, and custom TPU platforms) that rely on RDMA over Converged Ethernet (RoCE v2) or InfiniBand interconnects. In these environments, any packet loss or latency jitter directly impacts training efficiency. Thus, high-quality 800G transceivers manufactured under stringent optical testing protocols are critical to maintaining cluster uptime and minimizing overall TCO.
Leveraging 8-lane electrical interfaces (each running at 112Gbps PAM4) to achieve 800Gbps aggregate bandwidth in standard QSFP-DD and OSFP form factors.
Innovating with finned top designs for OSFP modules to dissipate up to 18-22 watts of heat, allowing stable long-term operations in hyperscale environments.
Utilizing state-of-the-art 7nm/5nm DSPs to perform continuous adaptive equalization, compensating for high-frequency signal degradation across copper and fiber media.
China is the global epicenter for the assembly, packaging, and testing of active optical transceivers. At Kocent Optec Limited, we have optimized our supply chain to provide stable capacity, competitive lead times, and rigorous quality control. Our factories incorporate highly automated production lines, ensuring that delicate sub-assemblies (such as TO-can packaging, TOSA/ROSA alignment, and lens positioning) are executed with sub-micron precision.
Furthermore, China’s industrial ecosystem provides unparalleled access to high-quality passive optics—such as MPO/MTP connectors, PLC splitters, and custom fiber patch cords—which are essential for dense patch-panel infrastructure supporting 800G arrays. This vertical integration allows us to significantly reduce turnaround times and mitigate geopolitical supply chain shocks, giving our international clients a decisive time-to-market advantage.
With more than 13 years of manufacturing telecommunication fiber optic products, we strictly follow international fiber optic industry standards. We use mature scientific methods to deliver your products on time and ensure that 100% of our products are thoroughly tested and inspected before shipment.
The roadmap for high-speed interconnects is progressing along two primary technological axes: packaging innovation and module architectures. While traditional DSP-based pluggable transceivers dominate the current landscape, new alternatives such as Linear-drive Pluggable Optics (LPO) and Co-Packaged Optics (CPO) are emerging. LPO removes the power-hungry DSP from the transceiver module, relying instead on the host ASIC’s high-performance SerDes to drive the optical link. This reduces module power consumption by up to 50% and latency by orders of magnitude—crucial parameters for high-frequency trading and tightly coupled GPU compute clusters.
| Parameters / Features | 800G OSFP/QSFP-DD (DSP) | 800G LPO (Linear Drive) | 1.6T OSFP-XD (Next-Gen) |
|---|---|---|---|
| Typical Power Consumption | 16W - 22W per module | 8W - 10W per module | 25W - 30W per module |
| Latency Profile | ~100ns (due to DSP processing) | <10ns (analog transit only) | ~120ns (DSP-based) |
| Transmission Distance | Up to 10km (SMF) / 100m (MMF) | Typically <500m (SMF / MMF) | Up to 2km (SMF initial release) |
| Key Components | 5nm DSP, EML / Silicon Photonics | High-bandwidth Driver/TIA, No DSP | 3nm DSP, 224Gbps SerDes, Thin-film LiNbO3 |
As electrical lane rates transition from 112Gbps to 224Gbps, signal integrity issues on host PCBs will amplify. CPO addresses this by placing the optical engines on the same multi-chip module substrate as the switch ASIC. This layout shortens the electrical path to millimeters, virtually eliminating trace loss and enabling higher switch bandwidth density (e.g., 51.2Tbps and 102.4Tbps switches). Kocent Optec Limited is actively tracking and developing passive optical alignment sub-components to support the eventual adoption of CPO platforms.
Deploying 800G QSFP/OSFP modules in leaf-spine architectures to reduce the total number of physical optical links while increasing traffic capacity. This deployment lowers space and cooling costs in data centers throughout North America and Europe.
Enabling high-throughput GPU interconnections with 800G SR8 modules and ultra-low-loss MTP/MPO trunk cables. This configuration supports parallel processing workloads and reduces GPU idle times during matrix multiplication calculations.
Connecting metro edge routers directly to regional cores. 800G coherent optics (such as 800G ZR/ZR+) allow carriers to extend high-capacity links up to 120km without needing expensive optical amplification infrastructure.
Years of sales and service experience have enabled us to win customers across different global regions. Today, our footprint spans East Asia, Southeast Asia, the Middle East, Eastern Europe, Western Europe, Northern Europe, South America, North America, North Africa, and South Africa.
Win-win cooperation is our constant goal. Many of our OEM and ODM products have won Telecom Operator tenders and continue to meet strict end-user requirements. Our primary terminal telecom operator clients include:
SingTel, Vodafone, America Movil, Telefonica, Bharti Airtel, Orange, Telenor, VimpelCom, TeliaSonera, Saudi Telecom, MTN, Viettel, Bitel, VNPT, Laos Telecom, MYTEL, Telkom, Telekom, Entel, FiberTel, StarFiber, Ooredoo, Beeline, Azercell, and others.
Deploying 800G optical infrastructure requires strict compliance with international trade and technical standards. Kocent Optec ensures all transceiver designs meet MSA (Multi-Source Agreement) specifications, ensuring seamless interoperability with hardware from leading OEMs such as Cisco, Arista, Juniper, and Huawei.
Additionally, our global logistics network and localized distribution partners offer regional support, technical troubleshooting, and fast replacement services. We maintain strict compliance with regulatory standards, including CE, FCC, RoHS, and REACH. Every batch of 800G OSFP and QSFP modules undergoes rigorous bit error rate (BER) testing, eye diagram analysis, and temperature chamber testing before leaving our facility.
