Description

The JL282A-BCC is a drop-in compatible replacement for the Aruba JL282A. This passive copper breakout cable connects one 100 Gigabit QSFP28 port to four 25 Gigabit SFP28 ports, providing plug-and-play compatibility with HPE Aruba Networking switches and HPE Comware-based devices. - Complies with IEEE 802.3bm 100GBASE-CR4 standard, ensuring reliable 100 Gbps operation over passive copper - QSFP28 to 4x SFP28 breakout architecture: one end with QSFP28 connector, opposite end with four independent SFP28 connectors - 1 metre cable length ideal for within-rack or adjacent-rack connections - Passive twinax design requires no external power, reducing heat and power consumption compared to active cables - Cost-effective alternative to optical transceivers for short-reach 100G to 4x25G connectivity - Hot-swappable for live network maintenance without disrupting adjacent ports

Features

• IEEE 802.3bm compliance guarantees interoperability with any MSA-compliant QSFP28 and SFP28 ports, enabling vendor-agnostic deployments across mixed infrastructure
• Four independent 25 Gbps electrical lanes on the SFP28 side allow each breakout leg to connect to a separate device or port without lane coordination required at the host
• Passive copper construction eliminates signal retiming or amplification, resulting in sub-microsecond latency and zero power draw beyond the host port itself
• QSFP28 host connector supports 100GBASE-CR4 electrical signalling with automatic link negotiation and FEC (Forward Error Correction) when enabled on the host platform
• Twinax cable geometry provides inherent EMI shielding and supports tight bend radius for high-density rack deployments without signal degradation
• Hot-pluggable design permits insertion and removal under power, with QSFP28 module management interface providing real-time cable presence and basic diagnostic visibility

FAQs

Q: Will this work in place of the Aruba JL282A?
A: Yes. This cable is a direct replacement for the Aruba JL282A. It uses the same QSFP28 to 4x SFP28 form factor, complies with the same IEEE 802.3bm 100GBASE-CR4 standard, and delivers the same 100 Gbps aggregate data rate (4x 25 Gbps lanes) over 1 metre of passive copper. It is plug-and-play compatible with any QSFP28 and SFP28 ports that support 100GBASE-CR4 signalling.

Q: Which HPE Aruba platforms support this cable?
A: This cable is compatible with HPE Aruba Networking switches and HPE Comware-based devices that provide QSFP28 100G ports on the host side and SFP28 25G ports on the breakout side. Confirm that your platform supports 100GBASE-CR4 (QSFP28) and 25GBASE-CR (SFP28) electrical interfaces. Consult the official HPE Aruba transceiver compatibility matrix for your specific switch model and software version to verify support.

Q: Can I connect all four SFP28 ends to different switches or servers?
A: Yes. Each of the four SFP28 connectors operates as an independent 25 Gbps link. The QSFP28 host port aggregates four lanes, and the cable splits them into four separate physical connections. Each breakout leg can connect to a different device, enabling one 100G port to feed four independent 25G devices. Lane assignment is handled automatically by the host switch.

Q: What is the maximum reach for passive copper breakout cables and why?
A: Passive copper cables are typically limited to 1-5 metres due to electrical signal attenuation over copper at 25 Gbps per lane. At 1 metre, the JL282A-BCC operates well within the IEEE 802.3bm specification for 100GBASE-CR4, ensuring low bit error rates without active signal conditioning. For longer distances, consider active copper or active optical breakout cables, which include signal retiming or optical conversion.

Q: Does this cable require FEC to be enabled on the switch ports?
A: FEC (Forward Error Correction) is recommended but not always mandatory for passive copper DAC cables at 1 metre. Many switches auto-negotiate FEC during link bring-up. The IEEE 802.3bm standard for 100GBASE-CR4 supports both Reed-Solomon (RS-FEC) and Base-R FEC. If you experience link instability or elevated error rates, enable FEC explicitly on both the QSFP28 and SFP28 ports according to your switch vendor's guidelines.
