Frequently Asked Questions

Will compatible optics work in my Cisco switch without errors?
Yes — modules are coded to the target Cisco platform so they are recognized like OEM optics. Tell us your switch model and we code to match. (Note: mixing third-party optics may affect OEM support terms; many customers run them in production regardless.)

Can you code a mix of part numbers on one order?
Yes. Provide the list of Cisco part numbers and quantities on your RFQ and we will code each line accordingly.

Do you also supply OEM Cisco optics?
Yes. If a contract requires genuine Cisco modules, we can quote OEM alongside the compatible option so you can compare landed cost.
