As the global digital economy accelerates, the demand for bandwidth is reaching unprecedented levels. The transition from 100G to 400G SFP (QSFP-DD/OSFP) is no longer a luxury but a necessity for hyperscale data centers, 5G telecommunications, and high-performance computing (HPC) environments. Globally, the 400G market is projected to grow at a CAGR of over 20% as enterprises replace legacy infrastructure to handle AI-driven traffic.
In North America and Europe, the push for 400G is driven by Cloud Service Providers (CSPs) like AWS and Microsoft. Meanwhile, in the Asia-Pacific region, led by China's manufacturing prowess, the focus is on achieving the perfect balance between high-density port configuration and thermal efficiency.
Unlike traditional NRZ, PAM4 allows double the bit rate in the same bandwidth. Our 400G SFP modules utilize advanced DSP and PAM4 technology to ensure signal integrity over longer distances.
The integration of optical and electronic components on a single chip is reducing the cost and power consumption of 400G transceivers, paving the way for 800G and beyond.
With QSFP-DD consuming up to 12-15W, advanced cooling designs and "finned top" heat sinks (as seen in our OSFP models) are becoming industry standards to prevent overheating.
Kocent Optec Limited, established in 2012 in Hong Kong as a hi-tech communication enterprise, is one of China's leading fiber optic termination product manufacturers and solution providers.

QSFP-DD (Quad Small Form-factor Pluggable Double Density) is backward compatible with QSFP28. OSFP (Octal Small Form-factor Pluggable) offers better thermal performance and is often used in massive AI clusters.
400G SR8 is ideal for short-reach (100m) multi-mode fiber in rows. 400G DR4 and FR4 cover medium distances (500m-2km), while 400G LR4 reaches up to 10km for campus or metro links.
At Kocent Optec, we utilize Agilent and Anritsu testing equipment to perform bit-error rate (BER) tests, eye diagram analysis, and compatibility verification for every 400G module.
