Dual-port QSFP28 plug-in card with two optical transceiver cages

Mellanox Technologies

Mellanox Technologies MCX416A-CCAT dual-port 100GBase-X QSFP28 network connector

SKU CH-BD28-4H0V9 MPN MCX416A-CCAT

Dual-port 100GBase-X adapter with PCIe 3.0 x16 host interface and QSFP28 slots for optical fibre

  • Dual 100 Gbps ports double server bandwidth
  • PCIe 3.0 x16 host interface feeds full line rate
  • Two QSFP28 cages accept optical fiber modules
  • Plug-in card form factor fits standard server slots
  • RoHS-6 certified build meets environmental standards

Dual-Port 100GBase-X Adapter

The Mellanox Technologies MCX416A-CCAT is a dual-port 100GBase-X QSFP28 network connector designed for server environments. It connects via a PCI Express 3.0 x16 host interface and supports optical fiber media. The plug-in card form factor fits standard server expansion slots. RoHS-6 certification confirms environmentally friendly manufacturing.

Suited for Dual-Port 100G Connectivity

This adapter suits administrators deploying two 100GBase-X links over optical fiber in servers with an available PCI Express 3.0 x16 slot. It is not for builders who need copper-based 100G connections, single-port density, or a different host interface such as OCP. Teams requiring more than two ports or a lower-speed Ethernet variant should look elsewhere.

PCI Express 3.0 x16 Host Interface

The PCI Express 3.0 x16 host interface is the specification that determines compatibility with the target server platform. Verify that the motherboard provides a full-length x16 slot wired for PCI Express 3.0 signalling. The card occupies one such slot and presents two QSFP28 cages for optical transceiver modules.

Questions about this item

How does the 100GBase-X rate translate to actual throughput when the MCX416A-CCAT is installed in a server?

Each of the two QSFP28 ports carries a 100GBase-X signal, so the card delivers up to 100 Gb/s per port when connected to matching optics and cabling.

What does the PCI Express 3.0 x16 host interface mean for bandwidth limits on this adapter?

The x16 lane width at PCIe 3.0 supplies enough upstream bandwidth to sustain both 100GBase-X ports simultaneously without host-bus saturation.

What physical slot and bracket space does the MCX416A-CCAT require inside a server chassis?

The plug-in card fits a standard PCI Express x16 slot and uses a single full-height bracket; the two QSFP28 cages protrude through that bracket for optical fiber connections.
