Cable InfiniBand/fibra óptica BlueOptics OS6560-CBL-300-BL

The BlueOptics OS6560-CBL-300-BL is a 3 meter passive 40GBase-CR4 Direct Attach Cable (DAC) with QSFP-to-QSFP connectors and 30 AWG twinax copper construction. MSA-compliant and compatible with the Alcatel‑Lucent OS6560-CBL-300 specification, this cable is designed for short-distance electrical signal transmission between hardware in the same rack or adjacent racks. It supports Ethernet, FCoE, Fibre Channel and InfiniBand applications at up to 40 Gbit/s over a 3 meter length and is intended for use in switches, routers, storage systems and other platforms that support the referenced original part.

Advantages

This BlueOptics Alcatel‑Lucent OS6560-CBL-300 compatible DAC offers low power consumption, low latency and a cost-effective connectivity option for short-reach links. Manufactured to MSA standards using components from established suppliers, the cable is tested for compatibility with vendor hardware and adapted to software requirements to ensure reliable operation. The construction and component selection contribute to an extended service life.

Key specifications

How to use

Before installation, verify that both connected devices officially support passive QSFP 40GBase-CR4 DACs. Insert each QSFP connector into the corresponding QSFP port on your switch, router or storage device until it latches. Use the cable for short-distance electrical connections (up to 3 m) and select the appropriate transmission settings on your equipment per vendor documentation. No external power or transceivers are required when using passive DACs; the link negotiation and signalling are handled by the host devices.

Recommendations

Handle the cable by the connector housings and avoid sharp bends; maintain the minimum bend radius specified by the hardware vendor. Confirm firmware and software compatibility on your devices and request a test sample when integrating into critical systems.
