## Summary description

The BlueOptics JNP-100G-4X25G-3M-BL is a 3-meter InfiniBand/fibre optic cable featuring a QSFP28 connector on one end and four SFP28 connectors on the other. This cable is designed for high-speed data transmission, making it ideal for data centers and networking applications. With its male/male connector configuration, it ensures reliable connectivity and performance in demanding environments.

## Long description

The BlueOptics JNP-100G-4X25G-3M-BL is a 3 metre direct attach cable (DAC) with a QSFP28 plug on one end and four SFP28 plugs on the other, designed for short-range, high-speed connections in rack environments. This cable supports 100GBase-CR4 / 4x25GBASE-CR electrical transmission over a 3 m twinax copper link and is suitable for linking switches, routers and storage devices that accept QSFP28 to 4xSFP28 connectivity. The passive twinax construction and MSA-compliant form factor make it a practical solution for dense cabling in data centres and adjacent rack setups.
Advantages
The cable offers electrical 100 Gbit/s throughput across four 25 Gbit/s lanes with low latency and low power consumption typical of passive twinax DACs. Its 26 AWG construction and QSFP28/SFP28 connector combination enable reliable short‑distance links without additional optical transceivers. Manufactured to MSA standards and built from well-known components, the cable is compatible with major hardware platforms that support the corresponding Juniper-style direct attach solution.
Suitable for
Top‑of‑rack and adjacent rack interconnects in data centres
Connecting QSFP28 ports to multiple SFP28 ports for 100G to 4×25G breakouts
High‑performance Ethernet, FCoE and InfiniBand short‑reach links
Switch-to-switch, switch-to-router and switch-to-storage direct connections
Key specifications
Length: 3 metres
Interface: QSFP28 (1 end) to 4 × SFP28 (other end)
Data rate: up to 100 Gbit/s (4 × 25 Gbit/s lanes)
Cable type: passive twinax copper (DAC), 26 AWG
Standards: 100GBase‑CR4 / 4x25GBASE‑CR electrical transmission
Form factor: MSA‑compliant QSFP28 and SFP28 connectors
How to use
Insert the QSFP28 connector into the host device QSFP28 port and plug each SFP28 connector into the corresponding SFP28 ports on the target device. Ensure ports are powered down or follow hot‑plug guidelines of the hardware vendor when connecting or disconnecting. For breakout operation, configure the switch or host to enable 4×25G lanes as required by the device firmware or operating system. Verify link status through device management interfaces after installation.
Usage recommendations
Use this passive DAC for short interconnects up to 3 m inside racks or between adjacent racks. Confirm that your network equipment firmware supports passive QSFP28-to-4×SFP28 breakout cables and that the ports are rated for 100GBase‑CR4/4x25GBASE‑CR operation before deployment to ensure compatibility and stable performance.
