Support Services for Infinera Products

The Infinera Call Center and Technical Assistance Center (TAC) support customers with Infinera products, including those carrying the Coriant, Transmode, Tellabs, Sycamore Networks, and NSN Optical brands.
For critical technical support requests and 4-hour advance hardware replacement requests, please call the Infinera Call Center at +1 408-572-5288 (in the US dial +1 800-443-5555 toll-free). The Infinera Customer Portal (https://support.infinera.com) is also available, but for immediate assistance we recommend that you call. These contact details are the same for all Infinera customers in all countries worldwide.
For non-critical technical support and hardware service requests, please use the Infinera Customer Portal at https://support.infinera.com. This Customer Portal Quick Reference Guide provides information that will help you log in and navigate the portal.
Infinera has also created a Technical Support Request Guide as well as a Return Material Authorization Guide to help you navigate our return process. If you have difficulty accessing or navigating the Infinera Customer Portal, our Call Center and TAC team are available to assist you.
