Compatibility
The Cisco documents cited in the sources list DS-SFP-FC64G-LW as an option for Cisco MDS 9124V. That listing is the only compatibility claim recorded here: the part is not assumed to fit other generations or other product lines of the same brand. Firmware, software, slot, backplane and controller requirements are set out in the vendor documentation for the specific product, and the vendor's compatibility tool should be checked before ordering a second-hand unit.
Buying used
Inspect the optical connector for scratches or dirt, read the module details from the switch (vendor name, part number, serial) and confirm the switch accepts it without an unsupported-module warning. Check the speed and reach on the label. Ask the seller for photos of the part number label, confirm the return terms, and test the part in a running system before accepting it. Prices vary with condition, so compare several listings for the exact product ID.
