Description

The JL284A-BCC is a drop-in compatible replacement for the Aruba JL284A. This passive direct attach copper breakout cable connects a single 100G QSFP28 port to four 25G SFP28 ports, delivering plug-and-play compatibility with Aruba switches supporting QSFP28 and SFP28 interfaces. - Passive copper design supporting 100Gbps aggregate bandwidth across four 25Gbps lanes - QSFP28 to 4x SFP28 breakout configuration with 5-metre cable length, 26AWG copper construction - Ideal for data centre aggregation and top-of-rack connectivity where a single 100G uplink feeds four 25G server or switch connections - Hot-swappable for deployment flexibility without network downtime - Complies with InfiniBand and Ethernet signalling standards for broad interoperability

Features

• QSFP28 to 4x SFP28 breakout architecture allows a single 100G switch port to connect to four independent 25G endpoints, maximising port density and reducing uplink oversubscription in aggregation layers
• Passive copper design eliminates power consumption and heat generation, making it suitable for densely populated racks where thermal budget and power draw are critical
• 26AWG copper construction balances signal integrity and cable flexibility over the 5-metre reach, supporting full 25Gbps per lane without external repeaters or power
• Each SFP28 lane operates independently, enabling mixed-speed deployments or incremental migration from 10G to 25G infrastructure without replacing the entire cable assembly
• Hot-swappable for in-service deployment and replacement, supporting operational flexibility during network expansions or topology changes
• Complies with InfiniBand and Ethernet electrical specifications, ensuring interoperability across multi-vendor environments and compatibility with FEC-enabled host interfaces

FAQs

Q: Will this work in place of the Aruba JL284A?
A: Yes. The JL284A-BCC is engineered to the same electrical and mechanical specifications as the Aruba JL284A, using the same QSFP28 to 4x SFP28 passive copper breakout design with 26AWG conductors and 5-metre reach. It is plug-and-play compatible with any Aruba switch or device that accepts the JL284A, delivering 100Gbps aggregate bandwidth across four independent 25Gbps lanes.

Q: Which Aruba switch platforms support this cable?
A: This cable is compatible with Aruba switches featuring QSFP28 uplink ports and SFP28 downlink or breakout capabilities, including models in the CX 6300, CX 8325, and other AOS-CX and AOS-S platforms with 100G and 25G port options. Verify your specific switch model supports QSFP28 and SFP28 form factors at the required data rates.

Q: Can I use all four SFP28 breakouts simultaneously at full 25Gbps per lane?
A: Yes. Each of the four SFP28 breakout legs operates as an independent 25Gbps lane, and all four can run concurrently at full line rate for a total of 100Gbps aggregate throughput. The passive copper design ensures signal integrity across all lanes without requiring external power or active electronics.

Q: What is the maximum reach for this passive DAC breakout cable, and does it support Forward Error Correction?
A: The maximum reach is 5 metres as specified by the passive copper design and 26AWG conductor gauge. This cable supports Forward Error Correction (FEC) if enabled on the host switch ports, which can improve bit error rate performance over copper at 25Gbps signalling rates, particularly in electrically noisy rack environments.

Q: Can I connect this cable to a mix of 10G SFP+ and 25G SFP28 ports on the breakout side?
A: No. Each SFP28 breakout connector is designed for 25Gbps signalling. While SFP28 ports are mechanically compatible with SFP+ form factors, this cable's electrical characteristics are optimised for 25Gbps operation per lane. Connecting to 10G SFP+ ports may not establish a link or may result in undefined behaviour depending on the switch's autonegotiation and signal detection logic.
