The QSFP-to-QSFP connectors enable straightforward cabling between switches, servers and storage adapters without additional transceivers, reducing power consumption and component count. The 0.5 m length minimizes cable slack and improves airflow in racks, and the robust construction ensures reliable mechanical and electrical performance over sustained use.
Suitable for
 Interconnecting QSFP ports on switches and servers in data centers
 High-performance computing (HPC) clusters using InfiniBand
 Short-reach links inside server racks and top-of-rack setups
 Direct cabling between storage controllers and host adapters
Key specifications

How to use
Install the BlueLan PAN-QSFP-DAC-0.5M-BL by aligning each QSFP plug with the corresponding QSFP port on your switch, server or adapter and inserting until the connector latches.
