This data sheet provides a technical overview of the Cisco SFP-10G-SR-S and its associated variants. Designed for high-speed 10 Gigabit Ethernet connectivity over multimode fiber, these “S-Class” modules are the enterprise standard for data centers and campus wiring closets in Pakistan.
Cisco SFP-10G-SR-S Overview
The Cisco 10GBASE-SR SFP+ module is a hot-swappable I/O device that plugs into a 10 Gigabit Ethernet SFP+ port. The “S” designation denotes “S-Class,” which is optimized for standard enterprise and data center applications, offering a more cost-effective alternative to non-S-Class modules by focusing on essential Ethernet protocols.

SFP-10G-SR Variants Available at SKYRS
SKYRS maintains a comprehensive inventory of 10G SR variants to meet diverse environmental and protocol requirements across Pakistan.
SFP-10G-SR-S (S-Class): Optimized for pure Ethernet applications. Ideal for switch-to-switch and switch-to-server connectivity within a rack or across adjacent racks.
SFP-10G-SR (Standard): Supports a broader range of protocols including FCoE (Fibre Channel over Ethernet) and OTN, suitable for high-end storage and telecom environments.
SFP-10G-SR-X (Extended Temperature): Designed for extreme environments with a wider operating temperature range (-5°C to 85°C).
SFP-10G-SR-I (Industrial): Ruggedized for industrial applications, supporting CPRI data rates and a temperature range of -40°C to 85°C.
Deployment and Installation
To ensure maximum link stability and hardware longevity, the SKYRS technical team recommends the following deployment standards:
Physical Installation:
Hot-Swappable: The SFP-10G-SR-S can be installed or removed without powering down the host switch or router.
Fiber Polishing: Use only LC-to-LC Duplex patch cords with PC or UPC polishing. APC (angled) connectors are not supported for these modules.
Dust Protection: Keep the protective dust plugs in the SFP+ port and on the fiber connectors until the moment of connection. Contamination is the #1 cause of link failure in Pakistan’s dusty environments.
Cabling Requirements:
OM3 Fiber: Supports up to 300 meters.
OM4/OM5 Fiber: Supports up to 400 meters.
FDDI-Grade Fiber: Supports up to 26 meters (legacy infrastructure).
Configuration and Availability Only at SKYRS
SKYRS provides specialized “Readiness and Verification” services for all transceiver deployments, ensuring the hardware is genuine and optimally configured.
Exclusive SKYRS Services:
Digital Optical Monitoring (DOM) Setup: SKYRS pre-configures the switch OS to provide real-time diagnostic alerts for temperature, voltage, and laser bias current.
Cisco Quality ID Verification: Every module is tested to ensure the host Cisco platform correctly identifies the “Cisco Original” ID, preventing “unsupported transceiver” errors.
Third-Party Compatibility Staging: For mixed environments (Aruba, Huawei, Juniper), SKYRS provides coded variants that ensure seamless cross-brand communication.
Local Staging in Karachi & Lahore: Same-day testing and configuration are available at our regional hubs for urgent 10G backbone upgrades.
Note: Advanced DOM diagnostic support and the specialized S-Class bulk-buy pricing are available exclusively through the SKYRS procurement network in Pakistan.
