Arista

Specifications

Description:

Arista CAB-Q-S-1M is a high-performance Twinax copper breakout cable designed to connect a single 40GbE QSFP+ port to four 10GbE SFP+ ports. At just 1 meter in length, this direct attach cable (DAC) is optimized for short-distance, high-speed interconnects in top-of-rack (ToR) or rack-to-rack deployments. Ideal for data centers, enterprise networking, and high-performance computing environments, this passive breakout cable ensures low latency and reliable connectivity without the need for additional transceivers.

Features:
Breakout Configuration:

One QSFP+ connector (40Gbps) splits to four SFP+ connectors (10Gbps each), supporting aggregated and segmented bandwidth applications.

High-Speed Transmission:
Supports up to 40 Gbps total bandwidth (10 Gbps per SFP+ channel), making it perfect for high-throughput networking demands.

Low-Latency Passive DAC:
Designed for short-range, low-power, and low-latency connections—no active electronics needed.

Plug-and-Play Compatibility:
Fully compliant with SFF-8436 (QSFP+) and SFF-8431 (SFP+) standards—ensures broad compatibility with major switch and router brands.

Compact 1-Meter Length:
Perfect for confined spaces or short-link requirements within server racks or between adjacent networking equipment.

Technical Specifications:

Cable Type: Twinax Copper – Passive DAC
Product Model: CAB-Q-S-1M
Part Number: CAB-Q-S-1M
Cable Length: 1 meter (3.3 feet)
Connector 1: 1 x 40GbE QSFP+
Connector 2: 4 x 10GbE SFP+
Data Rate: 40 Gbps (QSFP+), 10 Gbps (per SFP+)
Application: Breakout/aggregation of QSFP+ to SFP+
Compliance: IEEE 802.3ba, SFF-8436, SFF-8431
Cable Jacket: Durable, shielded copper cable
Power Type: Passive (no external power required)

Ideal Use Cases:

Data Centers: Connect high-speed switches to servers with 10GbE NICs in rack setups.
Enterprise Networks: Deploy in edge aggregation layers where 40GbE uplinks are broken out to multiple 10GbE downlinks.
High-Performance Computing (HPC): Reduce latency and cabling complexity in short-range, high-throughput compute clusters.
Top-of-Rack Networking: Achieve efficient port utilization with minimal cable clutter in tightly packed network racks.

Why Choose CAB-Q-S-1M?

Cost-effective solution for short-range, high-speed interconnects
Reduces need for separate transceivers
Simplifies cabling in dense environments
Maintains high signal integrity and data performance
Backed by wide compatibility and industry-standard design
