BlueOptics LSWM3STK-BL InfiniBand/kuitu-kaapeli 3 m SFP+ uros/uros

The BlueOptics LSWM3STK-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male connectors on both ends. It provides a direct connection for short-range high-speed links in racks and between adjacent racks, supporting data center and networking equipment that accept SFP+ interfaces. The cable is intended for low-latency, high-throughput applications and is suitable for use where a reliable 10 Gbit/s link is required over a 3 metre distance.

Advantages

This SFP+ male-to-male cable delivers stable 10 Gbit/s transmission over a 3 m span, using a passive direct-attach approach that requires no external power. The cable follows common MSA-compliant SFP+ physical specifications for broad compatibility and low interoperability risk. Its twinax construction provides low latency and low power consumption compared with active optical transceivers for equivalent short-range links.

Key specifications

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring the retainers click into place. Confirm that attached devices support passive direct-attach SFP+ twinax cables and that the link speed is configured or auto-negotiated to 10 Gbit/s where required. If a device requires vendor-validated cables, verify compatibility before deployment or test a sample in the target hardware to confirm operation.

Recommendations

For reliable operation, route the cable to avoid tight bends and mechanical stress, maintain proper airflow in racks, and use a length appropriate for rack layout—3 m for connections within or between adjacent racks. If you experience link issues, check device logs and ensure the hardware firmware supports passive DAC SFP+ modules.
