## Summary description

The BlueOptics XLDACBL05-BL is a 0.5 m InfiniBand fibre optic cable featuring QSFP connectors. It provides high-speed data transfer, ideal for data centers and high-performance computing environments. The male connectors ensure a secure connection, making it a reliable choice for demanding applications.

## Long description

The BlueOptics XLDACBL05-BL InfiniBand fibre optic cable 0.5 m QSFP is a short-reach, high-speed connection solution for rack-to-rack and intra-rack links. Designed with QSFP connectors and a 0.5 metre length, this cable supports InfiniBand and other 40G-class protocols for data centre and high-performance computing environments. The cable is intended as a passive direct attach solution for short distances and is compatible with hardware platforms that support QSFP 40G connections.
Advantages
This 0.5 m QSFP cable provides a compact and reliable physical link with low latency and low power consumption typical of passive direct attach assemblies. Manufactured to meet common multi-source agreement (MSA) interface specifications, it uses high-quality components and is tested for interoperability across standard switches, routers and storage systems. The cable offers a cost-effective alternative to optical transceivers for short-distance 40G links and is designed for stable performance and long service life.
Suitable for
Short-range 40G InfiniBand or Ethernet links inside racks and between adjacent racks
High-performance computing clusters and server-to-switch connections
Storage system interconnects and switch-to-switch aggregation ports
Environments that require low-latency, low-power direct attach solutions
Key specifications
Connector type: QSFP to QSFP
Cable length: 0.5 m
Supported data rate: up to 40 Gbit/s
Cable type: passive direct attach (twinax copper for equivalent products)
Compliance: MSA-form factor compatibility and industry conformity for 40G QSFP links
Typical power consumption: very low (passive assembly)
How to use
Install the BlueOptics XLDACBL05-BL by inserting each QSFP connector into the corresponding QSFP port on networking equipment, ensuring a secure mechanical latch. Use the 0.5 m length for short, direct connections between adjacent ports; verify that both devices support passive 40G direct attach links and the required protocol (InfiniBand, 40G Ethernet, FCoE or Fibre Channel as applicable). No additional configuration is required at the physical layer beyond ensuring that device firmware and port settings support the chosen protocol and link speed.
Usage recommendations
Use this cable only for short-distance links where passive QSFP direct attach assemblies are supported by the hardware vendor. Avoid running the cable through tight bends or high-temperature environments and ensure ports and connectors are free of dust before insertion. For deployments requiring longer reach or optical isolation, consider optical transceivers and fibre cabling instead.
