Description

The CAB-Q-S-xM-BCC is a drop-in compatible replacement for the Arista CAB-Q-S-1M. This passive copper breakout cable connects a 40GB QSFP+ port to four 10GB SFP+ ports, supporting Arista switches with QSFP+ and SFP+ interfaces. - Compliance with SFF-8436 (QSFP+) and SFF-8431 (SFP+) MSA standards ensures interoperability with Arista equipment - 40GBASE-CR4 to 4x 10GBASE-CU passive twinax construction, aggregate 40Gbps data rate with four 10.3125Gbps SFP+ channels - Supports 40 Gigabit Ethernet, 10 Gigabit Ethernet, InfiniBand QDR, and Fibre Channel applications - Available in 1M, 2M, 3M, and 5M lengths for flexible rack and adjacent-rack connectivity - Operating temperature 0 to 70 degrees C, hot-swappable for live installation

Features

• SFF-8436 and SFF-8431 MSA compliance guarantees mechanical fit and electrical signaling compatibility with Arista QSFP+ and SFP+ ports across platform generations
• Passive copper design eliminates external power requirements and delivers typical power consumption of 0.02W per cable assembly
• 40GBASE-CR4 electrical specification supports four independent 10Gbps lanes, enabling flexible port mapping from a single 40G port to four discrete 10G endpoints
• Twinax cable construction maintains signal integrity through controlled impedance and low pair-to-pair skew, critical for reliable 10Gbps per-lane operation
• Hot-swappable connectors with pull-to-release latching mechanism allow live insertion and removal without disrupting adjacent ports or requiring system shutdown
• Protocol-agnostic operation supports 40 Gigabit Ethernet, InfiniBand QDR, 10 Gigabit Ethernet, and Fibre Channel over the same physical assembly
• Four discrete SFP+ channels operate independently, allowing mixed link states and enabling gradual migration or asymmetric topologies

FAQs

Q: Will this work in place of the Arista CAB-Q-S-1M?
A: Yes. This cable is designed as a direct replacement for the Arista CAB-Q-S-1M and longer variants. It meets SFF-8436 QSFP+ and SFF-8431 SFP+ MSA specifications, supports 40GBASE-CR4 to 4x 10GBASE-CU electrical signaling, and provides plug-and-play compatibility with Arista switches featuring QSFP+ and SFP+ ports.

Q: Which Arista platforms support this breakout cable?
A: This cable is compatible with Arista switches that provide QSFP+ ports capable of 40G operation and SFP+ ports capable of 10G operation. The cable requires the host QSFP+ port to support 40GBASE-CR4 signaling and the SFP+ ports to support 10GBASE-CU. Consult the Arista Transceiver and Cable Guide for your specific platform and EOS version to confirm support.

Q: Can I connect all four SFP+ ends to different switches?
A: Yes. The four SFP+ channels operate as independent 10Gbps electrical lanes. Each SFP+ connector can terminate at a different switch, router, or host adapter, provided the upstream QSFP+ port is configured for 4x10G breakout mode. The host platform must support this mode in both hardware and software.

Q: What is the maximum reach for passive copper breakout cables?
A: Passive copper twinax cables are typically specified for distances up to 5 meters for 40GBASE-CR4 and 10GBASE-CU applications. Signal integrity degrades with length due to copper attenuation and crosstalk. For distances beyond 5 meters, consider active optical breakout cables or fiber transceivers with breakout harnesses.

Q: Does this cable require Forward Error Correction (FEC) on the host ports?
A: FEC requirements depend on the host platform and port configuration. Passive copper cables typically do not require FEC for short distances (1 to 3 meters) but may benefit from FEC at longer lengths (5 meters) or in environments with high electromagnetic interference. Consult the Arista platform documentation for FEC settings specific to breakout cables.
