Network transceiver module BlueOptics PAN-QSFP28-100GBASE-CWDM4-BO Fiber optic QSFP28 LC Aluminium 40g

The BlueOptics PAN-QSFP28-100GBASE-CWDM4-BO is a QSFP28 fiber optic transceiver module for 100G data links using CWDM4 transmission over single-mode fiber. Designed with an LC duplex connector and an aluminium housing, the module follows MSA-compliant QSFP28 form-factor specifications and weighs approximately 40 g. It supports high-speed Ethernet and Fibre Channel over Ethernet applications and is intended for installation in networking equipment that accepts QSFP28 optical modules.

Advantages

This transceiver provides up to 100 Gbps aggregate bandwidth over CWDM4 wavelengths, enabling high-capacity links with reduced electromagnetic interference compared to copper. The LC duplex interface allows simultaneous transmit and receive on separate fibers. The aluminium housing offers a compact, lightweight and thermally stable enclosure, while compliance with QSFP28 MSA ensures broad interoperability with devices that support QSFP28 optical modules. Built-in digital diagnostic monitoring (DDM/DOM) enables remote measurement of supply voltage, laser bias current, optical Tx/Rx power and temperature for simplified troubleshooting.

Suitable for

• 100G Ethernet interconnects in data centers and campus networks
• High-speed Fibre Channel over Ethernet links
• Aggregation and spine links between switches and routers
• Longer single-mode fiber runs where CWDM4 wavelength multiplexing is used (up to specified range)

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gbps (aggregate)
• Connector: LC duplex
• Transmission type: CWDM4 over single-mode fiber
• Housing material and colour: aluminium
• Weight: approx. 0.04 kg
• Digital Diagnostics Monitoring (DDM/DOM) support

How to use

Insert the QSFP28 module into a compatible QSFP28 port on switches, routers or other network devices while the host is powered down or following hot‑swap guidelines from the device vendor. Connect LC duplex single-mode patch cables to the module’s LC ports, ensuring correct transmit/receive orientation. Verify that the host device recognizes the module and that link parameters (speed, protocol) are configured as required. If available, enable DDM/DOM in the host to monitor operational parameters remotely.

Recommendations

Use single-mode LC duplex patch cords specified for CWDM4 wavelengths and follow the equipment vendor’s compatibility list. Confirm that the target hardware supports QSFP28 CWDM4 modules and the DDM/DOM feature to access diagnostic information. For stable performance, avoid tight bends in fiber and keep connectors clean; perform end-face inspection and cleaning before insertion.
