Arista SFP-10G Transceiver Modules are industry-standard SFP+ (Small Form-factor Pluggable) devices designed for high-performance 10 Gigabit Ethernet links. These modules are hot-swappable, allowing you to upgrade or replace them without powering down your Arista switches. They are essential for data center leaf-spine architectures, enterprise cores, and high-speed server uplinks.

Key Variants (Select the one you have):

• SFP-10G-SR (Short Range): Designed for multi-mode fiber (MMF). Supports distances up to 300m over OM3 fiber. Ideal for connections within a single rack or data hall.

• SFP-10G-LR (Long Range): Designed for single-mode fiber (SMF). Supports distances up to 10km. Ideal for campus-wide networking and building-to-building links.

• SFP-10G-T (Copper): Features an RJ-45 interface for use with standard Cat6a/7 copper cables. Supports distances up to 30m at 10Gbps.

Key Features:

• Hot-Swappable: Minimizes network downtime during maintenance or upgrades.

• Digital Optical Monitoring (DOM): Supports real-time monitoring of temperature, voltage, and optical power (for SR and LR models).

• Low Power Consumption: Optimized for high-density switch environments to reduce cooling costs.

• Full Compatibility: Specifically programmed and tested for seamless integration with Arista EOS-based switches.

The Arista 7140T-8S is a high-density 1U rack-mount switch designed for wire-speed Layer 2/3/4 switching. With 40 auto-negotiating 10GBASE-T ports and 8 SFP+ uplinks, it offers a total of 48 10GbE ports in a compact form factor. Running on the Arista Extensible Operating System (EOS), it provides industry-leading stability and programmability for modern cloud and enterprise networks.

Key Features:

• Ultra-Low Latency: Delivers a consistent latency of just 2.9 microseconds, making it ideal for time-sensitive applications and High-Performance Computing (HPC).

• Massive Throughput: Offers a switching capacity of 800 Gbps and a forwarding rate of 600 Mpps.

• Flexible Connectivity: 40 ports of 10GBASE-T (RJ45) allow you to use existing Cat6a/7 cabling, while 8 SFP+ ports provide fiber connectivity for long-range uplinks.

• Carrier-Grade Redundancy: Equipped with 1+1 hot-swappable 760W power supplies and N+1 redundant fans.

• Layer 3 Advanced Routing: Supports full IPv4 and IPv6 routing, including OSPF, BGP, and ECMP (Equal Cost Multi-Path) for scalable leaf-spine designs.
