------Question for BCM957412A4120AC Please Put your question below------
This product can be supported 10/100/1000M/2.5G/5G/10GBase-T Multi-rate SFP+ Module ?
Hi @nattapongb ,
The Broadcom BCM957412A4120AC is a dual-port 10GbE PCIe Gen3 x8 network interface card that supports SFP+ optical modules and copper direct-attach cables. It uses the BCM57412 MAC controller with integrated dual-channel 10GbE SFI transceivers.
While the card supports 10G SFP+ modules, compatibility with multi-rate SFP+ modules (supporting 10/100/1000M/2.5G/5G/10GBase-T) depends on:
- Firmware and PHY support: The BCM57412 controller is optimized for 10GBase-T and SFP+ modules but may not support all intermediate speeds (e.g., 2.5G/5G) unless explicitly stated.
According to the datasheet and confirmed support:
- 10GBase-T： Supported via copper direct-attach or compatible SFP+ modules.
- 1GBase-T： Often supported as fallback.
