Description

The CAB-SFP-SFP-0-5M-Arista is a high-performance 10G SFP+ passive direct attach copper twinax cable designed for short-reach data centre and enterprise connectivity. With a 0.5-metre cable length, it provides a cost-effective and low-power solution for connecting SFP+ ports on Arista switches, routers, and network storage equipment. Ideal for top-of-rack switching and high-density interconnects where reliable 10 Gigabit Ethernet performance is essential.

Features

MSA-compliant SFP+ connectors on both ends for reliable hot-pluggable connectivity
- Passive copper twinax design for low power consumption and minimal heat generation
- Supports 10 Gigabit Ethernet, 8G Fibre Channel, and Fibre Channel over Ethernet (FCoE)
- High-speed differential signalling for data rates up to 10.5 Gbps
- RoHS compliant and lead-free construction for environmental responsibility
- Cost-effective alternative to fibre optic transceivers for short-distance links
- Ideal for top-of-rack switching, server-to-switch, and switch-to-switch connectivity
- Operating temperature range from 0°C to 70°C for standard networking environments
- Compliant with SFP+ MSA standards SFF-8431, SFF-8432, and SFF-8472

FAQs

Q: What is the maximum distance supported by this cable?
A: The CAB-SFP-SFP-0-5M supports a maximum reach of 0.5 metres, making it ideal for short-range interconnections within racks or adjacent equipment.

Q: Is this cable compatible with other vendor equipment?
A: This cable is specifically coded for Arista Networks equipment. While it may work with other vendors' SFP+ ports, compatibility is not guaranteed. For cross-vendor deployments, verify compatibility or use vendor-neutral DAC cables.

Q: Does this cable require external power?
A: No, this is a passive copper cable that draws minimal power (maximum 0.57W per end) directly from the SFP+ port. No external power supply is needed.

Q: What is the difference between passive and active DAC cables?
A: Passive DAC cables like this one use copper conductors without signal amplification, making them lower cost and lower power. They are suitable for short distances up to 7 metres. Active cables include signal boosting for longer reaches.

Q: Can this cable support speeds lower than 10G?
A: Yes, the cable supports data rates ranging from 1.25 Gbps (Gigabit Ethernet) up to 10.31 Gbps, making it backward compatible with lower-speed SFP+ applications where the port supports rate adaptation.
