BlueOptics QSFP-100G-CWDM4-500-BO network transceiver module QSFP28 2000m

The BlueOptics QSFP-100G-CWDM4-500-BO is a QSFP28 fiber optic transceiver module engineered for high-speed networking and data center interconnects. It supports 100G transmission using CWDM4 wavelengths over single-mode fiber with a maximum reach of 2000 meters. The module is supplied in an aluminium housing, weighs 0.04 kg and uses a QSFP28 interface with LC duplex connections, providing a compact, industry-standard form factor for compatible network equipment.

Advantages

This transceiver offers support for 100GBASE-CWDM4 links at distances up to 2 km while maintaining industry-standard QSFP28 interoperability. The aluminium housing provides mechanical protection and thermal dissipation in rack and data center environments. Lightweight and compact, the module is designed to meet MSA-compatible form-factor expectations and to integrate with hardware platforms that support CWDM4 QSFP28 optics. Digital Diagnostics Monitoring (DDM/DOM) functionality enables real-time monitoring of operating parameters when the host system supports it.

Key specifications

How to use

Install the module into a compatible QSFP28 port on a switch, router or transceiver cage while following the host vendor's hot-plug instructions. Connect LC duplex single-mode fiber patch cords to the module's LC duplex connector, ensuring correct polarity for transmit and receive channels. Verify link status in the host device and, if available, access the DDM/DOM registers to monitor voltage, temperature, laser bias and optical power values. Remove protective dust caps from both the module and patch cord ends before insertion to avoid contamination.

Recommendations

Ensure compatibility with the target hardware platform and check that the target device supports CWDM4 100G optics and DDM/DOM access if diagnostics are required. Use suitable single-mode fiber patch cords and follow ESD handling precautions during installation. For prolonged reliability, maintain clean optical connectors and use proper patch panels or trunking to avoid sharp bends and mechanical strain on fiber runs.
