Cable de red BlueOptics 100G2X25GPD2M-LEG-BL QSFP 4xSFP28 InfiniBand 2 m negro

The BlueOptics 100G2X25GPD2M-LEG-BL QSFP to 4xSFP28 InfiniBand cable is a 2 meter, black high-performance network cable designed for data centre and high-speed networking environments. It provides a QSFP interface on one end and four SFP28 interfaces on the other, enabling a single 100G port to break out into four 25G links. The cable is intended for direct connection between switches, routers and servers where compact, reliable multimode/fibre connectivity is required.

Advantages

This cable offers a compact breakout solution that simplifies port aggregation and link consolidation without additional external hardware. Its four SFP28 terminations support parallel high-bandwidth lanes, enabling effective traffic distribution and reduced cabling complexity. The robust black jacket and factory-terminated connectors ensure consistent signal performance and durability in rack and cabinet installations.

Suitable for

• Breaking out a 100G QSFP port into four 25G SFP28 ports
• Direct connections between switches, routers and servers in data centres
• High-bandwidth InfiniBand or fibre optic links in short-reach applications
• Top-of-rack and intra-rack cabling where short, reliable links are needed

Key specifications

• Cable length: 2 m
• Connector A: QSFP
• Connector B: 4 × SFP28
• Colour: Black
• Weight: 0.26 kg

How to use

Connect the QSFP end to a compatible 100G QSFP port on a switch or adapter, and insert each SFP28 connector into the corresponding 25G SFP28 ports on target devices. Ensure ports are powered down or follow hot-plug guidelines specified by your hardware vendor when inserting or removing transceivers. Verify link status and negotiated speeds in your equipment management interface after connections are made.

Recommendations

For optimal performance, route the cable with minimal bends and avoid tight loops; maintain bend radius consistent with vendor guidance. Confirm compatibility of QSFP and SFP28 ports for breakout operation and ensure firmware or driver support for 4×25G mode on the host device. Use this 2 m cable for short-reach rack or cabinet connections rather than long-haul links.
