## Long description

The BlueOptics JL283A-BL InfiniBand fibre optic cable is a 3 m direct attach solution featuring a QSFP28 male connector on one end and four SFP28 male connectors on the other. Designed for short-reach, high-speed links, the cable supports up to 100 Gbps aggregated bandwidth using a 4x25G lane split and is intended for use in rack-to-rack or within-rack interconnects in data centres and networking equipment that accept QSFP28 to 4xSFP28 breakout connections.
Advantages
This QSFP28 to 4xSFP28 cable provides a compact, passive direct-attach option for high-speed InfiniBand and Ethernet environments. Its 3 m length and twinax construction enable low latency and low power consumption for short-distance connections. The product is manufactured to industry multi-source agreement (MSA) mechanical and electrical guidelines for QSFP28 breakout DACs and is compatible with commonly used hardware platforms that support the corresponding QSFP28/ SFP28 interfaces.
Suitable for
High-speed server-to-switch and switch-to-switch connections within racks
Short-reach aggregation of 100G links into 4×25G ports
InfiniBand and Ethernet fabrics requiring QSFP28 to SFP28 breakout
Data centre top-of-rack (ToR) and adjacent-rack cabling
Key specifications
Cable length: 3 metres
Connector type: QSFP28 (male) to 4×SFP28 (male) breakout
Aggregate data rate: up to 100 Gbps (4×25G lanes)
Cable type: passive direct attach (twinax) suitable for short distances
Wire gauge reference: 26 AWG
Compliance: designed to MSA guidelines for QSFP28 breakout DACs
How to use
Install the cable by inserting the QSFP28 end into the QSFP28 port of the source device and the four SFP28 ends into the corresponding SFP28 ports of the destination device or devices, ensuring correct alignment and full insertion until the connector latches engage. Confirm that the connected devices support passive QSFP28-to-4×SFP28 direct attach cables for the intended protocol (InfiniBand, Ethernet, FCoE or Fibre Channel) and configure the interfaces in the network equipment as required by the operating system or switch firmware. Monitor link LEDs and management interfaces to verify the link is up and negotiating at the expected speeds.
Usage recommendations
Use this 3 m passive QSFP28 to 4×SFP28 cable for short-distance connections inside racks or between adjacent racks. Avoid routing the cable through areas with excessive bending or mechanical stress; maintain the manufacturer’s minimum bend radius. For longer reaches or where active signal conditioning is required, consider optical transceivers or active DAC solutions compatible with your hardware.
