How to use

Install the QSFP28 module into a compatible 100G-capable QSFP28 port on switches, routers or optical equipment according to the host device instructions. Use single-mode fiber patch cords and appropriate LC duplex adapters or MPO-to-LC breakout assemblies as required by the LR4 interface. Ensure correct cable routing, secure connections and verify link status via the network device management interface. Follow manufacturer guidance for handling the optical interface and take electrostatic discharge precautions when inserting or removing the module.

Recommendations

For optimal performance, use single-mode fiber infrastructure certified for long-reach LR4 links and maintain clean connectors to minimize optical loss. Verify compatibility with the host device firmware and QSFP28 port settings; if necessary, update device drivers or firmware to support third-party transceivers. Monitor link parameters and perform routine inspections to ensure stable 100G operation.
