## Long description

The BlueOptics X66100-05-BL is a 0.5 m InfiniBand/fibre optic cable with QSFP connectors on both ends. Designed for high-speed data transfer in data centers and networking environments, this cable provides a short, reliable connection for switches, servers and storage devices where low latency and stable signal integrity are required. The blue jacket and QSFP form factor make it suitable for dense rack installations and adjacent-rack links.
Advantages
This 0.5 m cable supports up to 40G data rates over a short reach, offering a cost-effective solution for direct connections between compatible hardware. The passive design reduces power consumption and potential points of failure while MSA-compliant QSFP connectors ensure wide compatibility with major vendors' equipment. The cable is manufactured using quality components to provide consistent performance and long service life in professional networking environments.
Suitable for
Direct links between QSFP ports on switches and routers in racks
Server-to-switch connections in high-performance computing and data centers
Storage system interconnects and short-range InfiniBand links
Applications requiring low latency and high throughput over short distances
Key specifications
Cable length: 0.5 m
Connector type: QSFP to QSFP
Supported protocol: InfiniBand and 40G Ethernet (40GBase-CR4 compatible)
Cable jacket color: blue
Passive twinax copper construction for short-range electrical signal transmission
Wire gauge: 30 AWG
How to use
Ensure both devices support passive QSFP direct attach twinax connections and the required transmission protocol (InfiniBand, Ethernet, or Fibre Channel over appropriate interfaces). Insert each QSFP connector firmly into the corresponding port until the latch engages. Route the 0.5 m cable within the rack or between adjacent racks avoiding sharp bends and mechanical stress. For passive twinax use, confirm the host hardware and firmware accept passive cables; no external power or transceiver modules are required.
Usage recommendations
For reliable operation, verify compatibility with your switch, server or storage vendor documentation before installation. Keep the cable length appropriate for short-range links (0.5 m) and avoid excessive bending or repeated flexing. Use in controlled rack environments and replace the cable if connectors show wear or if link errors occur.
