The Cisco SFP-10G-SR is a 10GBASE-SR SFP (Small Form-Factor Pluggable) module manufactured by Cisco Systems. It is a multimode fiber optic transceiver designed to support high-speed data communication over short distances.

The SFP-10G-SR module operates using 850nm wavelength signals and is compatible with OM3 (Optical Multimode 3) fiber optic cables. OM3 is a type of multimode fiber with a core size of 50 microns and is capable of supporting higher bandwidth over longer distances compared to older multimode fiber types.

The SFP-10G-SR module supports a link length of up to 400 meters when used with OM3 fiber optic cables. The link length refers to the maximum distance that the transceiver can reliably transmit data without signal degradation or loss.

The module provides a data transfer rate of 10 gigabits per second (10G), which makes it suitable for high-bandwidth applications such as data centers, enterprise networks, and storage area networks (SANs). It uses the SR (Short Reach) standard, which is designed for short-distance transmissions within a building or a local area network (LAN).

Overall, the Cisco SFP-10G-SR module is a reliable and widely used transceiver for short-range, high-speed data communication over multimode fiber optic cables.

Key features of the Cisco SFP-10G-SR module:

1. Data Rate: The module supports a data transfer rate of 10 gigabits per second (10G), enabling high-speed communication for bandwidth-intensive applications.

2. Fiber Type: The SFP-10G-SR module is designed for use with multimode fiber (MMF) cables. Specifically, it is compatible with 4700MHz KM MMF (OM3) cables.

3. Link Length: When used with 4700MHz KM MMF (OM3) cables, the SFP-10G-SR module can support a link length of up to 400 meters. This allows for flexible connectivity within a data center or local area network (LAN) environment.

4. Wavelength: The module operates using 850nm wavelength signals, which are commonly used for short-range multimode fiber applications.

5. Connector Type: The SFP-10G-SR module typically uses LC (Lucent Connector) duplex connectors for fiber optic cable connections.

6. Compatibility: The module is compatible with a wide range of Cisco networking equipment, including switches, routers, and other devices that support SFP transceivers.

7. Hot-Swappable: The SFP-10G-SR module is hot-swappable, meaning it can be inserted or removed from a compatible device without interrupting network operations. This feature facilitates easy installation and maintenance.
