## Long description

The BlueOptics JL284A-BL InfiniBand fibre optic cable is a 5 m connection solution with a QSFP28 connector on one end and four SFP28 connectors on the other. Designed for high-speed data transmission in data centers and networking environments, this QSFP28 to 4xSFP28 cable supports breakout configurations and links between servers, switches and storage systems where a 100G QSFP28 port must be split into four 25G SFP28 links. The cable is offered as a passive direct attach option suitable for short-reach, rack-to-rack or within-rack connections.
Advantages
This cable provides compact QSFP28-to-4xSFP28 breakout connectivity over a 5 m length, enabling consolidation of high-density ports and simple splitting of a 100G interface into four 25G links without additional transceivers. The male/female connector arrangement increases compatibility with a range of hardware and the passive construction offers low latency and low power consumption for short-distance applications. The product follows widely used industry form-factors and is intended for use in environments that require reliable, high-throughput links.
Suitable for
Breaking out a 100G QSFP28 port into four 25G SFP28 connections
Short-reach connections within racks and between adjacent racks (5 m)
Connecting servers, switches and storage systems that support QSFP28 and SFP28 interfaces
Key specifications
Cable type: QSFP28 to 4xSFP28 breakout
Length: 5 metres
Supported data rates: QSFP28/4x25G (100G breakout to 4×25G)
Connector configuration: QSFP28 on one end, four SFP28 on the other
Construction: passive direct attach twinax-style cable for short-distance links
How to use
Connect the QSFP28 plug to the 100G QSFP28 port on your switch or server and insert the four SFP28 plugs into the corresponding 25G SFP28 ports on the target devices. Ensure ports are powered down or follow your equipment maker’s hot-plug guidance when inserting or removing the cable. Verify that the target hardware supports passive breakout cables and the applied 100G-to-4x25G configuration in firmware or switch settings before use.
Usage recommendations
Use this cable for short-distance, high-density breakout tasks inside racks or between adjacent racks. Confirm interoperability with your hardware vendor and test a sample in your environment if required. Avoid routing the cable through long pathways or using it for distances beyond 5 m to maintain signal integrity and expected performance.
