Description

Cisco 10GBASE-SR SFP+ Module for MMF, 10G Ethernet, ON-OFF Operation, Gold, Multicolor

Crucially, regarding Multimode Fiber (MMF) Optimization, the 10GBASE-SR is exclusively designed for use with multimode fiber optic cables.  it operates at a short wavelength of 850 nanometers (nm), which is, in turn, optimized for transmission over MMF using cost-effective Vertical-Cavity Surface-Emitting Lasers (VCSELs).

Moreover, the achievable link length with a 10GBASE-SR module significantly depends on the type and quality of the multimode fiber used:

• For instance, it achieves 26 meters over older FDDI-grade (62.5/125 µm) MMF.
• Conversely, it extends up to 300 meters over newer, laser-optimized OM3 (50/125 µm, 2000 MHz*km) multimode fiber.
• And finally, it can reach up to 400 meters over even higher-performance OM4 (50/125 µm, 4700 MHz*km) or OM5 multimode fiber.

Additionally, the Dual LC Connector is a notable feature; specifically, the module utilizes a dual LC/PC connector, a widely adopted, compact, and high-density fiber optic connector type, thereby facilitating efficient cabling in densely populated network racks.

Consequently, DOM is invaluable for troubleshooting, performance validation, and proactive network health management.

Also, for convenience and efficiency, being an SFP+ form factor, the 10GBASE-SR module is hot-swappable.

Finally, concerning Industry Standards Compliance, the 10GBASE-SR fully complies with the IEEE 802.3ae 10GBASE-SR standard, thus ensuring interoperability with other compliant 10GbE networking equipment from various vendors. In addition, it adheres to the SFP+ Multi-Source Agreement (MSA), which, importantly, defines standardized form factors and interfaces.

Considering Typical Use Cases:

• Connecting servers to top-of-rack (ToR) switches in data centers.
• Similarly, inter-switch links within the same rack or adjacent racks.
• And furthermore, providing high-speed backbone connections within a single building or a small campus.
