Dual-port adapters are the workhorses of the GRT catalogue. Two ports in a single slot serve three recurring designs: redundant uplinks to two switches, bonded links that aggregate bandwidth and survive a cable failure, and — in the bypass family — the in/out pair of an inline appliance. The pattern repeats at every speed: dual gigabit RJ45 on the FF-902TBP bypass card, dual SFP28 on the F2502E OCP card, dual QSFP28 on the FF-1102E, and dual optical ports on the F1102EBPLR bypass card.
Specifying a dual-port card starts with what the second port is for. Redundancy wants the two ports on separate switch paths; bonding wants a switch that speaks the same aggregation; bypass wants the pair wired so the card — not the cabling — decides the path state. Our product pages document the port arrangement of each model, and our engineers will check your intended topology when you inquire.

Can the two ports run at different speeds or media?
On cage-based models each port takes its own module, so media can differ per port. Link speeds follow the adapter design; ask for the specific model behaviour.
Is a quad-port option available?
The wider server NIC range includes quad-port specifications. Tell us the speed and port count you need and we will send matching models.
