SFP-10G-SR-S - Cisco 10GB SFP+ S Class SR Module MMF

Cisco SFP-10G-SR-S — 10GBase-SR SFP+ Transceiver

What it is

The Cisco SFP-10G-SR-S is a 10 Gigabit Ethernet SFP+ fiber transceiver designed for short-range, high-speed connections over multimode fiber. It’s commonly used for switch-to-switch links, server connections, and high-density data center environments.

Why buyers pick SFP-10G-SR-S (plain English)

• 10 Gigabit speed: Delivers high-bandwidth connectivity for modern networks.

• Short-range fiber: Ideal for data centers, wiring closets, and campus buildings.

• SFP+ form factor: Compact and hot-swappable for easy deployment and upgrades.

• Reliable Cisco optics: Built for compatibility with Cisco 10G SFP+ platforms.

• Cost-effective 10G fiber: Lower cost than long-range optics when distance is short.

Where it fits (and when to choose something else)

Perfect for:

• Data center switch-to-switch links

• Server and storage connectivity

• Short-range 10G campus links

• High-density SFP+ environments

Choose something else if:

• You need longer distances → use 10GBase-LR

• You only need Gigabit → use 1000Base-SX/LX

• You’re using single-mode fiber → SR won’t work

TL;DR

SFP-10G-SR-S is a Cisco 10G SFP+ multimode fiber transceiver for short-distance, high-speed links — a go-to choice for data centers and campus networks.
