TP-Link Omada SM9220-1M InfiniBand/fibre optic cable QSFP28 Twinax Black

SM9220-1M is a passive Direct Attach Cable (Twinax) with a length of 1 meter and QSFP28 connectors on both ends, designed for short-distance transmission of 100 Gbps data. Manufactured by TP‑LINK for rack-to-rack and intra-rack connections, this cable provides a compact, low-latency connection option for data centers and enterprise networking equipment.

Advantages

The cable supports 100 Gbps data transmission and uses QSFP28 connectors on both sides for direct compatibility with QSFP28 ports. As a passive Twinax assembly, it offers low power use and low latency for short links up to 1 m. The design allows hot-swappable installation and a jacket made of OFNR or PVC depending on the variant, providing standard durability and flexibility for typical data center environments.

Suitable for

• High-speed rack-to-rack connections in data centers
• Short-distance links between adjacent switches or servers
• 100 Gbps QSFP28 network ports and devices
• Environments requiring low-latency direct attach cabling
