QSFP-transceiver BlueOptics QSFP-100G-LR4-C-BO 10000 m aluminium

The BlueOptics QSFP-100G-LR4-C-BO is a QSFP28 fiber optic transceiver module designed for 100GBASE-LR4 long-reach optical links. Housed in an aluminium casing and weighing approximately 40 g, the module supports single-mode fiber transmission up to 10,000 meters and uses an LC duplex connector. It implements a four-wavelength CWDM transmitter and receiver to carry up to 100 Gbit/s over standard LR4 links and is suitable for use in compatible network switches, routers and storage systems that accept QSFP-100G-LR4-C form-factor transceivers.

Advantages

The module follows MSA-compliant QSFP28 mechanical and optical specifications and provides interoperability with devices that support the QSFP-100G-LR4-C type. Its aluminium housing offers mechanical robustness while keeping weight low. Built with industry-standard optical components, the transceiver supports Digital Diagnostics Monitoring (DDM/DOM) to report supply voltage, laser bias current, transmit power, receive power and temperature for remote monitoring and troubleshooting. The design supports Ethernet, Fibre Channel over Ethernet and SDH/SONET high-speed applications at 100 Gbit/s over long distances.

How to use

Insert the QSFP-100G-LR4-C-BO module into a compatible QSFP28 slot on the target switch, router or host device and secure it according to the hardware manufacturer's instructions. Connect single-mode LC duplex fiber patch cords with correct polarity between transceivers or via a patch panel. Ensure the host device firmware and configuration support 100GBASE-LR4 operation and, if required, enable DDM/DOM monitoring in the management interface to read diagnostic values. Follow standard ESD precautions during handling and only operate the module within the temperature and power ranges specified by the system vendor.

Recommendations

For optimal link performance, use high-quality single-mode fiber and LC duplex patch cords, verify fiber polarity, and confirm that the remote end supports LR4 QSFP28 modules. If monitoring is required, check that the network device exposes DDM/DOM readings to the management system. Perform end-to-end testing after installation to validate signal levels and error statistics.
