100G QSFP SR4
The 100G QSFP SR4 optical transceiver is designed for use in 100-Gigabit Ethernet links up to 100m over Multi-Mode Fiber. It integrates 4 data lanes in each direction with 4×25Gb/s data rate, each lane operating on 850nm wavelength. The product is compliant with IEEE 802.3bm 100GBASE-SR4. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA.

Q: What fiber type and distance does this 100G QSFP SR4 module support?
A: It works on multimode fiber (OM3 or OM4) with an MPO‑12 connector. Maximum reach is 70 meters on OM3 and 100 meters on OM4. For longer distances, you would need a single‑mode module like PSM4 or CWDM4.
Q: What is the power consumption and does it need extra cooling?
A: Maximum is typically around 2.5W (check your specific module specs). That's low – no extra cooling is needed in standard data center environments (0‑70°C). You can populate adjacent ports without overheating.
Our Commitment to Quality
Quality is built into every module we ship, not just claimed. Our ISO 9001‑certified management system governs everything from component sourcing to final assembly. Each transceiver undergoes 100% end‑of‑line testing – including optical power, sensitivity, eye mask compliance, and DDM accuracy – before it is sealed and labeled.
We also take regulatory compliance seriously. All our products are RoHS compliant (free of hazardous substances), REACH compliant (registration of chemical substances), and bear the CE mark for European market access. These certificates are not just paperwork; they reflect our disciplined approach to material selection, production traceability, and environmental responsibility.
When you buy from us, you get a fully tested module backed by a systematic quality framework. No shortcuts. No guesswork. Just reliable optics that meet international standards – from our factory to your network.
