Weighing only 40 g, it is suitable for various networking applications.

## Long description

The BlueOptics 100G-4WDM-QSFP40KM-BO network transceiver module is a compact fiber optic interface designed for 100000 Mbit/s data links. With a QSFP28 form factor, silver housing and a lightweight construction of 40 g, this module provides a practical option for high-density network environments. The specification includes an expected mean time between failures (MTBF) of 1,000,000 hours, making it suitable for installations where uptime and predictable service life are required.
Advantages
The QSFP28 interface supports 100G connections in a small, standardized module that simplifies upgrades and port density management. The module’s lightweight metal enclosure and compact dimensions reduce the physical footprint in switches and routers while providing mechanical robustness. A high MTBF value indicates long operational life and lower likelihood of unplanned replacements, and the module’s silver finish allows easy visual identification in mixed equipment racks.
Suitable for
 Data center spine and leaf switches requiring 100G uplinks
 High-throughput aggregation and core network links
 Telecommunication transmission segments over single-mode fiber
 Upgrading existing infrastructure to higher-speed QSFP28 ports
Key specifications
 Interface type: QSFP28
 Maximum data transfer rate: 100000 Mbit/s
 Form factor: QSFP28 optical transceiver module
 Weight: 0.04 kg
 Housing colour: silver
 Designed for fiber optic connections and long-distance links (optical reach depends on fiber and optics used)
 High reliability with MTBF of approximately 1,000,000 hours
How to use
Install the BlueOptics QSFP28 module into a compatible QSFP28 transceiver slot on a switch, router or optical transport platform while the host device is powered down or following the vendor’s hot-swap guidelines. Connect appropriate single-mode fiber patch cords and ensure correct polarity and clean connector end-faces before insertion. After physical installation, verify link status and configure interface parameters on the host system as required for speed, FEC and lane mapping. Monitor the port for stable link indicators and check logs for any alarms related to the transceiver.
Usage recommendations
Use factory-quality single-mode fiber and LC/APC or LC/UPC connectors as required by the transceiver’s optical specification, and follow optical safety guidelines when handling fiber connections. Keep connector end-faces clean using approved cleaning tools, avoid excessive bending of fibers, and store the module with protective caps when not in use. For optimal performance, match the module’s optical characteristics with compatible network equipment and perform compatibility checks with the host vendor’s transceiver support list.
