Description

The R0Z25A-BCC is a drop-in compatible replacement for the Aruba R0Z25A. This passive copper direct-attach cable connects Aruba switches equipped with 100G QSFP28 ports for short-reach interconnects within and across racks. - 100GBASE-CR4 compliance ensures interoperability with Aruba networking equipment using QSFP28 interfaces - QSFP28 to QSFP28 passive twinax copper cable, 100 Gbps aggregate data rate across four 25 Gbps lanes - Passive copper design requires no external power, reducing operating cost and heat output compared to active solutions - Available in 1 meter, 3 meter, and 5 meter lengths to suit different rack configurations and spacing requirements - SFF-8665 and SFF-8636 compliant form factor and management interface for seamless integration

Features

• Four-lane architecture operating at 25 Gbps per lane to deliver 100 Gbps aggregate throughput over passive copper pairs
• 100GBASE-CR4 and IEEE 802.3bm compliance guarantees electrical interoperability with Aruba QSFP28 ports and other vendor platforms supporting the standard
• SFF-8665 mechanical specification and SFF-8636 management interface ensure form factor compatibility and host system identification via EEPROM product data
• Passive copper construction eliminates active signal conditioning, reducing power draw to approximately 1.5W per connector end and minimizing thermal load in high-density environments
• Suitable for short-reach data center interconnects up to 5 meters, offering cost-effective alternative to optical modules for same-rack or adjacent-rack switch fabric connections
• Hot-swappable design supports installation and removal without disrupting adjacent ports or powering down the host switch
• Commercial temperature range (0°C to 70°C) suitable for typical controlled data center environments

FAQs

Q: Will this work in place of the Aruba R0Z25A?
A: Yes. This cable is electrically and mechanically compatible with the Aruba R0Z25A based on the 100GBASE-CR4 standard, QSFP28 form factor, and 100 Gbps data rate. It is a plug-and-play replacement requiring no configuration changes.

Q: Which Aruba platforms support this cable?
A: This cable works with any Aruba switch equipped with 100G QSFP28 ports that support 100GBASE-CR4, including the Aruba 8325-32C and 8325-48Y8C switch series. Verify your platform has QSFP28 ports rated for 100G operation.

Q: Can I mix different cable lengths in the same switch fabric?
A: Yes. Each cable operates independently, so you can use 1m, 3m, and 5m variants within the same switch or across different switches without performance impact. Signal integrity is maintained across all passive copper lengths up to 5 meters.

Q: Does this cable support Infiniband EDR in addition to Ethernet?
A: Yes. The same QSFP28 passive copper assembly supports both 100 Gigabit Ethernet (100GBASE-CR4) and Infiniband EDR (Enhanced Data Rate) at 100 Gbps, as both protocols share the same physical layer signaling and QSFP28 connector standard.

Q: What is the maximum reach limitation for passive copper at 100G?
A: Passive copper cables at 100 Gbps are typically limited to 5 meters due to signal attenuation and timing constraints across four parallel lanes. Beyond 5 meters, active copper (with signal conditioning) or optical solutions are required to maintain link integrity.
