How to use
Insert the SFP+ module into an available SFP+ slot on a compatible switch or router until it clicks into place, then connect single-mode LC fiber cables to the LC ports. Verify link status through the device management interface and monitor DDM parameters as needed. The module is hot-swappable, so it can be inserted or removed without powering down the host device if the equipment supports hot-swapping.
What to consider before purchase
Ensure the target switch or router supports compatible SFP+ transceivers and accepts third-party modules.
Confirm your network uses single-mode fiber and LC connectors.
Verify required link distance does not exceed 40 km.
Check that device firmware or vendor restrictions will not prevent module operation.
Usage recommendations
Use certified single-mode LC fiber cables, check DDM readings periodically for signal and temperature status, and keep spare modules on hand for faster replacement during maintenance or upgrades.
