eSFP-GE-SX-MM850Accessories

The Cisco eSFP-GE-SX-MM850 is a hot-swappable Gigabit Ethernet SFP transceiver designed to deliver reliable, high-speed optical connectivity for enterprise and data center networks. Supporting data rates up to 1 Gbps, it operates over multimode fiber (MMF) using an 850 nm wavelength laser, ensuring stable and efficient short-range transmission.

This module enables link distances of up to 550 meters when used with 50/125 µm MMF and up to 220 meters on 62.5/125 µm MMF, making it an ideal solution for intra-building or campus-level connections. It is fully compliant with the SFP Multi-Source Agreement (MSA), ensuring interoperability with a wide range of Cisco switches, routers, and optical networking devices.

The eSFP-GE-SX-MM850 offers Digital Optical Monitoring (DOM) capabilities to track critical parameters like temperature, voltage, and optical power, enhancing network reliability and maintenance efficiency. Designed for energy efficiency and durability, this SFP module helps maintain network uptime while reducing operational costs.
