Cisco 10GBASE-SR SFP Module, Up to 400m on OM3 Multimode Fiber (SFP-10G-SR)

The SFP-10G-SR is a high-performance, hot-swappable SFP+ (Small Form-Factor Pluggable Plus) optical transceiver module designed for 10 Gigabit Ethernet (10GbE) connectivity over short distances. Ideal for data centers, enterprise networks, and server-to-switch links, this module delivers reliable, low-latency performance within the same rack or building. With support for OM3 and OM4 multimode fiber, 850nm VCSEL lasers, and Digital Optical Monitoring (DOM), the SFP-10G-SR ensures efficient transmission, real-time diagnostics, and easy installation in Cisco and MSA-compliant networking equipment.

Product Features

Short-Range 10GbE Connectivity

Supports high-speed 10GbE links over multimode fiber, reaching up to 400 meters on OM4 and 300 meters on OM3, making it ideal for intra-building and data center applications.

Digital Optical Monitoring (DOM/DDM)

Provides real-time monitoring of temperature, optical power, and voltage, ensuring reliable network operation and early detection of potential issues.

Hot-Swappable Design

Allows installation or removal without powering down the host device, minimizing network downtime and simplifying upgrades or replacements.

Multiple Variants for Specialized Environments

Available in standard, S-Class (budget-friendly Ethernet-only), extended temperature (SR-X), and industrial-grade (SR-I) models to meet different operational and environmental requirements.

IEEE 802.3ae Compliance

Fully compliant with 10GBASE-SR/SW standards, ensuring broad compatibility with Cisco and other networking devices, and supporting limiting receiver functionality for simplified host design.

High-Quality Optical Transmission

Utilizes 850nm VCSEL lasers and PIN photodiodes to maintain signal integrity, low attenuation, and stable 10GbE performance over multimode fiber.
