The Genuine Cisco SFP-10G-SR-S is a short-reach S-Class transceiver designed for reliable, high-density 10 Gigabit Ethernet connectivity in enterprise and data center networks. It delivers 10GBASE-SR performance over multimode fiber (MMF) and is optimized for modern switching environments like Top-of-Rack (ToR) and spine-leaf deployments.
As an S-Class module, the SFP-10G-SR-S provides cost-effective 10G connectivity with the quality and compatibility Cisco is known for—factory sealed and ready to deploy.
What Is S-Class? Comparing SFP-10G-SR-S vs. SFP-10G-SR
Cisco’s S-Class optics offer targeted functionality for Ethernet-only applications at a more affordable price point.
-
SFP-10G-SR-S (S-Class): Ideal for standard 10GBASE-SR connections in controlled environments. Does not support DOM (Digital Optical Monitoring), making it perfect for cost-sensitive deployments where real-time diagnostics are not essential.
-
SFP-10G-SR (Standard): Offers broader compatibility across older protocols like Fibre Channel and typically includes DOM support. Suitable for mixed-use cases requiring wider compatibility.
By choosing S-Class, you're selecting a streamlined, efficient solution tailored for today's 10G Ethernet backbone.
