Cisco SFP-10G-SR

Key Features and Specifications

The "SFP" in the name stands for Small Form-factor Pluggable, and the "SR" stands for Short Reach. Here are its main characteristics:

• Data Rate: It supports a data rate of 10 Gbps.

• Wavelength: It operates at an 850 nm wavelength, which is ideal for short-reach connections over multimode fiber.

• Fiber Type: It works with multimode fiber (MMF). The maximum transmission distance depends on the type of MMF cable used:

  • OM3: up to 300 meters (984 feet).

  • OM4: up to 400 meters (1,312 feet).

  • OM1 (FDDI-grade): up to 26 meters (85 feet).

• Connector: It uses an LC duplex connector.

• Form Factor: The module is a SFP+, which is a more compact version of the original SFP, designed to support 10 Gbps data rates.

• Hot-Swappable: You can install or replace the module without needing to power down the system, which is crucial for maintaining network uptime.

• Digital Optical Monitoring (DOM): Most versions of the SFP-10G-SR support DOM, a feature that provides real-time monitoring of key parameters like optical input/output power, temperature, and voltage.

Use Cases

The SFP-10G-SR is widely used in environments where high-speed, short-distance connections are needed. Typical applications include:

• Data Centers: For connecting servers to switches and switches to other switches within a data center rack or across adjacent racks.

• Enterprise Networks: For backbone connections between switches in different wiring closets or on different floors of a building.

• Storage Area Networks (SANs): Used in Fibre Channel over Ethernet (FCoE) applications.
