QSFP28 Transceiver BlueOptics QSFP28-100G-CLR4-2KM-BO 100G 2KM

The BlueOptics QSFP28-100G-CLR4-2KM-BO is a 100G fiber-optic transceiver module with a QSFP28 interface designed for high-speed single-mode links up to 2 km. Housed in a durable metal enclosure and weighing approximately 40 g, the module uses LC duplex connectors and implements 100GBASE-CWDM4 transmission. It supports common high-speed protocols and is intended for integration into data center switches, routers and other network equipment that accept QSFP28 optical modules.

Advantages

This QSFP28 transceiver offers 100 Gbit/s line rate over single-mode fiber with a maximum reach of 2000 m, supporting simultaneous transmit and receive via LC duplex interfaces. The metal housing provides mechanical robustness and thermal stability while the compact QSFP28 form factor allows high port density in network equipment. The module includes digital diagnostic monitoring functionality for real-time reporting of supply voltage, temperature and optical parameters when supported by the host device.

Key specifications

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on your switch, router or optical device following the host manufacturer's hot-plug and handling procedures. Connect LC duplex single-mode fiber patch cords to the transmit and receive lanes, ensuring correct polarity. Confirm link parameters and enable any required software or firmware support for third-party optics on the host device. If the host supports digital diagnostics, monitor supply voltage, temperature and optical power readings to verify link health.

Recommendations

Use single-mode LC duplex patch cords rated for CWDM4 and ensure end-to-end polarity and connector cleanliness. Verify that the host hardware and firmware accept QSFP28 third-party optics and enable DDM/DOM support if available for remote diagnostics. For stable long-term operation keep the module within the equipment manufacturer's specified temperature range and avoid mechanical stress when inserting or removing the transceiver.
