QSFP Transceiver BlueOptics QSFP-100G-CWDM4-S-BO 100G 3.3V

The BlueOptics QSFP-100G-CWDM4-S-BO is a 100G QSFP28 fiber optic transceiver module designed for high-speed optical links in data center and carrier networks. It supports 100GBASE-CWDM4 transmission over single-mode fiber and uses an LC duplex connector. The module operates at 3.3V and has a compact, lightweight metal housing in silver, allowing straightforward integration into QSFP28-compatible ports on switches, routers and storage systems.

Advantages

This QSFP transceiver provides 100 Gbit/s aggregate throughput with CWDM wavelength multiplexing for up to multi-kilometer links, while maintaining a small 3.3V power footprint and a 4 g weight. It is built to MSA QSFP28 mechanical and electrical standards and includes digital diagnostic monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, optical transmit/receive power and module temperature. The metal housing and industry-standard LC duplex connector ensure mechanical robustness and reliable optical mating.

How to use

Install the BlueOptics QSFP-100G-CWDM4-S-BO by inserting the module into a compatible QSFP28 port until it latches. Use LC duplex single-mode fiber patch cords and, if required, CWDM-capable patch panels or multiplexers to achieve the specified link distances. Confirm that the host hardware supports 100GBASE-CWDM4 and DDM/DOM if you plan to monitor diagnostics. Follow vendor guidance for hot-plugging and ensure proper ESD precautions during handling. After insertion, verify link status and optical power levels via the host system or the DDM interface.

Recommendations

Use certified single-mode LC duplex fiber and maintain clean connectors to preserve optical performance. Verify compatibility with the target switch or router firmware and enable DDM/DOM support in the host for proactive monitoring. For long-haul or multiplexed CWDM deployments, plan channel allocation according to CWDM grid specifications and use appropriate passive or active CWDM components.
