## Summary description

The BlueOptics QSFP28-DAC-2M-SO is a 2-meter InfiniBand/fibre optic cable with QSFP28 connectors on both ends. It is designed for high-speed data transmission and is ideal for connecting devices in data centers. The male/male configuration ensures compatibility with various equipment, providing reliable performance for demanding applications.

## Long description

The BlueOptics QSFP28-DAC-2M-SO is a 2-meter direct attach copper/fibre optic compatible cable with QSFP28 connectors on both ends, engineered for high-speed InfiniBand and data center interconnects. Its male-to-male QSFP28 termination supports line rates used in 100GbE and 100Gb INF architectures, enabling low-latency, high-throughput links between switches, servers and network adapters. The cable's 2 m length balances reach and signal integrity for rack-to-rack and in-rack connections.
Advantages
The cable provides a compact, low-power solution for short-reach, high-bandwidth connections with QSFP28 connectivity. Its fixed 2 m length reduces signal loss compared with longer passive links and simplifies cable management in dense installations. The male/male QSFP28 ends ensure broad compatibility with QSFP28 ports and modules, while the design targets consistent performance for latency-sensitive applications.
Suitable for
 Connecting QSFP28 ports between switches and routers in data centers
 Direct server-to-switch or server-to-server high-speed links
 InfiniBand clusters and HPC interconnects requiring low-latency cabling
 Short-reach 100Gb Ethernet links inside racks and between adjacent racks
Key specifications
 Cable length: 2 meters
 Connector type: QSFP28 male on both ends
 Supported interface: InfiniBand and 100 Gigabit Ethernet link rates
 Application: Direct attach for short-reach high-bandwidth connections
 Form factor: QSFP28 direct attach assembly suitable for dense rack environments
How to use
Install the cable by inserting each QSFP28 male connector firmly into the respective QSFP28 port on your devices, ensuring correct orientation. Verify link negotiation and port status in the switch or host interface, and route the cable to avoid sharp bends and mechanical stress. For passive assemblies, no additional power or configuration is required beyond standard port configuration; for active assemblies, confirm device compatibility and any required firmware settings.
Usage recommendations
 Use the 2 m QSFP28 assembly for short, direct links where low latency and minimal insertion loss are priorities. Avoid tight bends and secure the cable to prevent movement in high-vibration environments. Check compatibility with QSFP28 ports on your equipment and verify firmware or driver support for QSFP28 direct attach connections where necessary.
