Cisco SFP-10G-ER

The Cisco SFP-10G-ER is a small form-factor pluggable (SFP) transceiver module designed for use in high-speed data communication networks. It is specifically designed for long-range optical connectivity, offering a reach of up to 40 kilometers (24.85 miles) over single-mode fiber. The SFP-10G-ER supports 10 Gigabit Ethernet (10GbE) and can operate at a wavelength of 1550nm. It uses an LC duplex connector for fiber optic connections and supports digital optical monitoring (DOM) functionality, allowing for real-time monitoring of transceiver parameters such as temperature, optical power levels, and voltage. This transceiver module is commonly used in enterprise and service provider networks for applications that require long-distance connectivity, such as connecting data centers, metropolitan area networks (MANs), and wide area networks (WANs).
