Ports on E4G series routers are compatible with a variety of optical modules, including SFP, SFP+, and XFP modules.
Extreme Networks optical modules are tested to work in all supported Extreme Networks devices. We recommend that all customers use Extreme Networks optical modules in their Extreme Networks devices. Extreme Networks assumes no liability for third-party optical modules. Although Extreme Networks does not block third-party optical modules, we cannot ensure that all third-party optical modules operate properly in all Extreme Networks devices. The customer assumes all risks associated with using third-party optical modules in Extreme Networks devices.
For details about which optical modules are supported for use with E4G series routers, see the Extreme Hardware/Software Compatibility and Recommendation Matrices.
