FAQs

Q: How does the TR model differ from SE in features?
A: TR is tuned for high-throughput packet transport with a streamlined feature set, while SE provides richer service features for PE/edge use cases.

Q: What optics can I use on this card?
A: SFP/SFP+ for 1/10G and QSFP28 for 100G, subject to platform support. Always validate against the official optics compatibility list.

Q: Is 2T/slot achievable in any chassis?
A: You need compatible high-capacity fabric modules and sufficient fabric bandwidth in the chassis to realize 2T/slot.

Q: Does it support MPLS-based services?
A: Yes, the TR variant supports MPLS transport; service scope depends on software version and licensing.

Q: Can I mix 1G and 10G on the same card?
