Description

The Arista CAB-SFP-SFP-1.5 is a 1.5-meter passive direct attach copper (DAC) twinax cable designed for high-speed 10GbE connectivity between SFP+ devices. This cost-effective alternative to optical transceivers provides low-latency, reliable data transmission for short-reach applications in data centers, top-of-rack switching, and network storage deployments. Compliant with SFF-8431 and SFF-8472 standards, it supports 10GBASE-CR, 8G Fibre Channel, and FCoE applications.

Features

Passive copper twinax design for low power consumption and cost efficiency
- SFP+ MSA compliant for broad interoperability with networking equipment
- Supports 10GBASE-CR Ethernet, 8G/10G Fibre Channel, and FCoE protocols
- Low-latency data transmission ideal for high-performance computing and storage
- Hot-pluggable design for easy installation and maintenance without downtime
- RoHS compliant and lead-free for environmental compliance
- Operating temperature range of 0°C to 70°C for standard data center environments
- Suitable for top-of-rack switching, server-to-switch, and switch-to-switch connectivity

FAQs

Q: What is the maximum distance supported by the CAB-SFP-SFP-1.5?
A: This passive DAC cable supports up to 1.5 meters of reach, making it ideal for short-distance connections within a rack or between adjacent racks in data center environments.

Q: Is this cable compatible with non-Arista equipment?
A: While designed for Arista switches and routers, passive DAC cables typically work with other vendors' SFP+ ports. However, compatibility depends on the host device's acceptance of third-party optics and cable EEPROM encoding.

Q: What are the advantages of DAC over fiber optic cables?
A: DAC cables are more cost-effective than fiber transceivers and cables for short reaches, consume less power, generate less heat, and require no optical cleaning or maintenance. They're ideal for connections under 7 meters.

Q: Can this cable support 1GbE or only 10GbE?
A: The CAB-SFP-SFP-1.5 is designed primarily for 10G applications, though some SFP+ ports support backward compatibility to 1GbE. Check your switch documentation to confirm multi-rate support on specific ports.

Q: Does this cable require any additional licensing or configuration?
A: No, this is a passive copper cable that requires no software licensing or special configuration. It provides a simple plug-and-play connection between compatible SFP+ ports.
