## Summary description

Compatible NetApp BlueOptics QSFP28 transceiver X65406-BO supporting 100GBASE-CWDM4 over singlemode fiber with LC-duplex interface. Provides 4xWDM channels, up to 2 km reach and supports DDM/DOM for remote monitoring. Operates in 0°C to +70°C range. Designed for high-speed data center and metro links requiring compact, hot-pluggable 100 G optics.

## Long description

The Transceiver BlueOptics QSFP28 X65406-BO 100GBASE-CWDM4 LC-Duplex Singlemode 2 km DDM is a compact, hot-pluggable optical module designed for 100 Gigabit Ethernet links over singlemode fiber. It implements the CWDM4 specification with four wavelength channels multiplexed within a QSFP28 form factor and provides an LC-duplex electrical/optical interface. The module supports a reach of up to 2 kilometers and includes digital diagnostics monitoring (DDM/DOM) for real-time status of optical power, temperature and module supply.
Advantages
This QSFP28 transceiver offers a space-efficient solution for high-density 100 G ports and is compatible with standard QSFP28 cages and optics bays. The CWDM4 multiplexing reduces the number of fibers required compared with parallel optics while maintaining singlemode reach for data center and short metro links. Integrated DDM enables network administrators to monitor operating parameters remotely for improved fault detection and maintenance planning. Operating over a standard commercial temperature range, the module is suitable for typical indoor networking environments.
Suitable for
 100 Gigabit Ethernet links in data centers
 Short metro and campus interconnects up to 2 km
 High-density switch and router uplinks using QSFP28 ports
 Environments requiring remote optical diagnostics (DDM/DOM)
Key specifications
 Interface: QSFP28 form factor with LC-duplex optical connector
 Protocol: 100GBASE-CWDM4 (4-channel CWDM multiplexing)
 Fiber type: Singlemode fiber (SMF)
 Maximum reach: Up to 2 km over singlemode fiber
 Monitoring: Digital diagnostics monitoring (DDM/DOM) supported
 Operating temperature range: 0°C to +70°C
 Hot-pluggable design for easy insertion and replacement
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or media converter while the host device is powered according to the equipment manual. Connect LC-duplex singlemode fiber patch cables to the module’s optical ports observing correct transmit/receive alignment. Allow the device and module to negotiate link parameters; monitor the link and module status via the host device management interface or the module’s DDM values. For safe handling, avoid touching the optical interfaces and keep dust caps on unused connectors until connection.
Usage recommendations
Use clean, singlemode LC patch cords and confirm fiber polarity before powering operational links. Regularly check DDM readings for transmit/receive power and temperature to detect degradation early. Store spare modules in anti-static packaging and protect optical connectors with dust caps when not in use.
