## Summary description

The BlueOptics JNP-100G-DAC-2M-BL is a 2-meter InfiniBand/fibre optic cable featuring QSFP28 male connectors on both ends. It is designed for high-speed data transmission, ensuring reliable connectivity in data centers and networking environments. This cable supports 100G data rates, making it ideal for demanding applications.

## Long description

The BlueOptics JNP-100G-DAC-2M-BL is a 2‑meter QSFP28 to QSFP28 direct attach cable (DAC) designed for short-reach high‑speed connections in racks and between adjacent racks. As a passive 100G twinax copper cable compliant with MSA standards, it supports 100GBase‑CR4 transmission and is suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications at up to 100 Gbit/s on a 2 m link. The cable features 30 AWG conductors and QSFP28 male connectors on both ends for direct hardware interconnection in data centers and networking environments.
Advantages
The passive twinax design provides low power consumption and low latency for short-distance links while avoiding the need for active components. MSA-compliant construction and the use of high-quality components ensure broad compatibility with major switches, routers and storage systems that support 100GBase‑CR4 DACs. The 2 m length is optimized for rack-to-rack and in-rack connections, offering a compact, cost-effective alternative to active optical transceivers for supported hardware.
Suitable for
Rack-to-rack and in-rack 100 Gbit/s links in data centers
High-throughput connections between switches, routers and storage arrays
Short-reach InfiniBand, Ethernet, FCoE or Fibre Channel links up to 2 m
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 2 meters
Data rate: up to 100 Gbit/s (100GBase‑CR4)
Cable type: passive twinax copper (30 AWG)
MSA compliant design for cross-vendor compatibility
Typical use case: short-reach interconnects inside and between racks
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring that the connectors are fully seated and latched if the port uses a latch mechanism. Confirm that both devices support passive 100G DACs and the 100GBase‑CR4 electrical interface. No external power or additional modules are required for passive operation. Verify link status on connected devices and check speed/duplex settings in the host or switch management interface as needed.
Usage recommendations
Use this 2 m passive DAC for short, direct connections inside racks or between adjacent racks where both endpoints explicitly support passive QSFP28 DACs. Avoid routing the cable through hot-plenum air paths or bending below the manufacturer’s minimum bend radius. For longer distances or where device support for passive DACs is uncertain, consider active optical transceivers or verified vendor-compatible alternatives.
