How to use

Install the Extralink QSFP28 module into a compatible QSFP28 slot on a switch, router or network interface card while the host device is powered according to vendor guidance. Connect the appropriate fiber patch cable to the optical interface, ensuring the fiber type and connector match the module requirements. Verify link status in the host device management interface and confirm that the negotiated data rate is 100 Gb/s. Follow the equipment manufacturer's hot-plug and ESD handling instructions when inserting or removing the module.

Recommendations

Use multimode or single-mode fiber and connector types that meet the module's optical specifications, maintain clean fiber endfaces, and ensure fiber routes adhere to bend-radius and environmental limits. Verify compatibility with the host device firmware and maintain proper inventory of spare modules for critical links.
