BlueOptics QSFP-H40G-CU2M InfiniBand optický kábel 2 m čierny

The BlueOptics QSFP-H40G-CU2M InfiniBand fibre optic cable 2 m Black is a 2-meter direct-attach cable with male QSFP connectors on both ends, intended for short-reach, high-speed interconnects in data centers and networking racks. It supports InfiniBand and QSFP form-factor ports to provide a straightforward physical link between compatible switches, host channel adapters (HCAs) and other QSFP-equipped devices, offering predictable latency and consistent signal integrity for server-to-switch or switch-to-switch connections.

Advantages

This cable provides a compact, low-latency connection using the QSFP interface and is designed for reliable short-distance transmission. Its fixed length of 2 m simplifies cable management in rack systems and reduces the need for transceivers or separate fiber patching. The black jacket adds a neutral appearance suitable for dense cabling environments, while the QSFP male-to-male termination ensures plug-and-play installation with compatible ports.

Suitable for

• Server-to-switch connections in data center racks
• Switch-to-switch uplinks within the same equipment room
• High-performance computing (HPC) clusters using InfiniBand
• Top-of-rack and middle-of-row interconnects

Key specifications

• Cable type: Direct-attach QSFP to QSFP
• Connector type: Male QSFP on both ends
• Length: 2 m
• Color: Black jacket
• Application: InfiniBand and QSFP-compatible high-speed links

How to use

Insert each QSFP connector into the corresponding QSFP port until the connector latches. Verify link status on connected devices and ensure ports are configured to support the intended InfiniBand or Ethernet mode as required by the network. Route the cable to avoid sharp bends and maintain recommended bend radius; secure with cable ties or management panels to prevent strain on the connectors. For installation in populated racks, label both ends to document the connection points.

Recommendations

Use this 2 m BlueOptics QSFP direct-attach cable for short-reach links where a fixed-length, low-latency QSFP connection is required. Avoid exceeding recommended bend radius, minimize mechanical stress on connectors, and confirm compatibility with device QSFP ports and firmware to ensure optimal performance.
