Cavo in fibra ottica InfiniBand BlueOptics 4D6W8-BL 2 m SFP+ connettore maschio/connettore maschio

The BlueOptics 4D6W8-BL is a 2 m InfiniBand/fibre optic direct attach cable with SFP+ male-to-male connectors designed for short-reach, high-speed links in rack and adjacent-rack environments. It supports 10G data rates and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications where a reliable SFP+ passive connection is required. The cable implements a twinax/passive direct attach topology that delivers low latency and low power consumption for data center interconnects and high-performance computing setups.

Advantages

The cable provides a compact SFP+ male/male interface for plug-and-play connectivity without the need for optical transceivers. Its passive twinax construction keeps power draw minimal while maintaining signal integrity for distances up to 2 meters. Components and construction follow common MSA guidelines to ensure interoperability with major networking, switching and storage platforms that accept SFP+ direct attach cables. The design results in a cost-effective, low-latency link with an expected long service life under normal operating conditions.

Suitable for

• Short-distance connections between switches and servers in racks
• Inter-rack links across adjacent rack rows
• 10 Gigabit Ethernet, FCoE, Fibre Channel and InfiniBand connections
• High-performance computing clusters and storage arrays

Key specifications

• Cable type: passive twinax direct attach (SFP+ to SFP+)
• Length: 2 meters
• Connector: SFP+ male on both ends
• Supported data rate: up to 10 Gbps
• Wire gauge: 30 AWG
• Applications: Ethernet, FCoE, Fibre Channel, InfiniBand

How to use

Insert the SFP+ connector into the SFP+ ports of the two devices to be connected, ensuring the latch engages securely on each end. Verify that both devices are configured to accept passive direct attach twinax cables and that their firmware or software settings permit the use of non-active SFP+ modules. Once connected, confirm link status and negotiated speed on both devices. For safe handling, avoid sharp bends and excessive pulling on the cable and route it to minimize mechanical stress.

Recommendations

Use this 2 m SFP+ passive cable for short link distances inside racks or between adjacent racks where low latency and low power consumption are priorities. Ensure compatibility by checking device support for passive SFP+ DACs and keep cable bend radius within manufacturer guidelines to preserve signal quality and longevity.
