Key Features

Positioning: Cost-effective, entry-level version.
Functionality: Supports only 10GBASE-SR Ethernet; does NOT support FCoE (Fibre Channel over Ethernet).
Best Use Cases:
Standard 10G Ethernet links in data centers and enterprise networks.
Environments where only basic 10G connectivity is needed, with no storage or FCoE requirements.
Customers seeking budget-friendly 10G optical modules for routine aggregation or access.
Other Notes:
S-Class modules are ideal for typical data traffic, not for converged Ethernet/storage applications.

Applications Scenarios

Data Centers

High-performance 10G aggregation and access links for top-of-rack and end-of-row deployments.

Enterprise Core & Distribution

Scalable 10 Gigabit Ethernet backbone connectivity across campus or wiring closets.

Service Providers

Reliable 10G optical links for Metro Ethernet and transport aggregation.
