Key Features

0.5 m fixed cable length for adjacent equipment
QSFP28 interface for 100G-class ports
100GBASE-CR4 copper interconnect
InfiniBand EDR compatibility
NVIDIA-compatible connectivity
Connect compatible QSFP28 endpoints across a fixed 0.5 m copper link.

Create a short 100 GbE or InfiniBand EDR connection between compatible QSFP28 ports without selecting separate optical modules and fiber patch cables. The Axiom Memory 980-9I621-00E00A-AX is specified as a 0.5 m 100GBASE-CR4 direct-attach copper cable, providing a fixed-length copper link for equipment installed in the same rack or immediately adjacent rack positions. QSFP28 connectivity supports 100G-class interfaces used in dense server, storage, and network environments. The CR4 designation identifies a four-lane 100 Gigabit copper connection, while InfiniBand EDR compatibility makes the cable applicable to supported high-performance computing and storage-fabric equipment. NVIDIA compatibility is named for deployments that use compatible NVIDIA networking hardware. Its 0.5 m length distinguishes this cable for very short interconnects where excess cable length can obstruct airflow or complicate rack routing. Use it for direct connections between a QSFP28 adapter and a nearby switch port, between adjacent network devices, or for compact storage and compute fabric links. Confirm that both endpoints provide compatible QSFP28 100 GbE or InfiniBand EDR interfaces before installation.

Ideal For

Adjacent-rack 100 GbE switch-to-server connections using compatible QSFP28 ports.
Short InfiniBand EDR links in compute clusters and storage fabrics.
Direct QSFP28 connections where a 0.5 m cable reduces excess rack cabling.

Why This Product

1Fixed 0.5 m reach for adjacent-device QSFP28 links.
2Combines 100GBASE-CR4 Ethernet and InfiniBand EDR application support.
3Specifies compatibility with NVIDIA networking equipment.
4Uses a direct-attach copper construction rather than separate transceivers and fiber.

Frequently Asked Questions

What is included with 980-9I621-00E00A-AX?▾

980-9I621-00E00A-AX denotes a 0.5 m QSFP28 direct-attach copper cable for 100GBASE-CR4 Ethernet and InfiniBand EDR connections. It is the cable component used to connect two compatible QSFP28 endpoints at short range.

What ports does this cable connect?▾

This cable is specified with QSFP28 connectivity at both ends. It requires compatible QSFP28 interfaces on the equipment being connected and is intended for 100 GbE or InfiniBand EDR applications using the stated 100GBASE-CR4 cable format.

When should I use the 0.5 m cable length?▾

Use a 0.5 m cable when both endpoints are installed very close together, such as adjacent ports in the same rack. The short length helps avoid excess cable slack around dense switch, server, storage, or compute equipment.

Is this cable compatible with NVIDIA networking equipment?▾

Yes. NVIDIA compatibility is specified for this QSFP28 cable. Endpoint compatibility still depends on the installed port type and supported connection mode, so both devices should provide compatible QSFP28 100 GbE or InfiniBand EDR interfaces.
