## Summary description

The BlueOptics YFNDD-BL is a high-performance InfiniBand/fibre optic cable with a length of 2 meters. It features a QSFP28 connector on one end and four SFP28 connectors on the other, providing excellent data transfer capabilities. The male/male configuration ensures easy connectivity. This cable is ideal for high-speed networking applications, delivering reliable performance and durability in demanding environments.

## Long description

The BlueOptics YFNDD-BL QSFP28 4xSFP28 InfiniBand 2m Orange is a 2 meter high-performance direct attach cable (DAC) designed for short-range, high-speed links in racks and between adjacent racks. With a QSFP28 connector on one end and four SFP28 connectors on the other, the cable supports 100GBase-CR4 and 4x25GBASE-CR electrical transmission and is suitable for InfiniBand, Ethernet, FCoE and Fibre Channel applications where a male-to-male passive twinax copper assembly is required. The cable is orange in colour and built to MSA-compliant specifications using 26 AWG conductors for reliable 100 Gbit/s operation over 2 meters.
Advantages
This BlueOptics direct attach cable offers a compact and low-latency connection option that requires no external transceivers or additional power for passive operation. MSA-compliant construction and the QSFP28 to 4xSFP28 form factor enable straightforward connectivity to hardware that supports the corresponding 100GBase-CR4 / 4x25GBASE-CR interfaces. The short 2 m length and twinax copper design provide low power consumption and predictable signal integrity for rack-level and adjacent-rack connections, while its rugged connectors and industry-grade components support consistent performance in demanding data centre environments.
Suitable for
 100GBase-CR4 and 4x25GBASE-CR rack interconnects
 InfiniBand high-speed links between switches and servers
 Short-distance Ethernet, FCoE and Fibre Channel connections
 Patching within and between adjacent server racks
Key specifications

 Supported protocols: Ethernet, InfiniBand, FCoE, Fibre Channel (as supported by host hardware)
 Colour: Orange
 Weight (approx.): 0.25 kg
How to use
Verify that the network devices (switches, routers, servers, storage) explicitly support passive QSFP28-to-4xSFP28 DAC connections and the relevant transmission protocol. Align the QSFP28 and SFP28 connectors with their respective ports and insert until the latches engage; do not force connectors. Ensure both ends are properly seated before powering equipment. For cable routing, avoid sharp bends below the manufacturer recommended bend radius and keep the 2 m length free from tight kinks or heavy strain. The cable is intended for short-range electrical connections in data centre rack environments and should not be used where optical transceivers or active repeaters are required.
Usage recommendations
Use this cable for direct rack-level and adjacent-rack links where passive twinax DACs are supported by the host hardware. For longer distances or cross-room links, select active optical cables or transceiver-based fiber solutions. Inspect connector contacts for debris before insertion and follow the host vendor compatibility list to ensure full functionality.
