Key specifications

How to use

Install the QSFP28 module into a compatible QSFP28 port on switches, routers or host adapters while the system supports hot-plug operations. Connect single-mode fiber using the appropriate MPO/MTP or LC breakout cabling and ensure correct polarity and fiber type. Verify link status and optical power levels using network management tools or the host device's interface. Replace or remove the transceiver following the device manufacturer's hot-swap procedure to avoid interruption.

Recommendations

For reliable long-reach performance, use single-mode fiber rated for LR4 optics and follow manufacturer guidelines for maximum link distance. Verify compatibility with the host device's supported QSFP28 LR4 transceivers and ensure fiber connectors and patch panels are clean and tested before deployment.
