The Cisco SFP-10G-ER-S is a small form-factor pluggable (SFP) transceiver module manufactured by Cisco Systems. It is designed for use in high-speed data communication networks and supports 10 Gigabit Ethernet (10GbE) connections. The "ER" in the product name stands for "Extended Reach," indicating that this transceiver is capable of transmitting data over longer distances compared to standard SFP modules. The "S" in the name denotes that it is a single-mode fiber module. The SFP-10G-ER-S supports a maximum link length of up to 40 kilometers (24.85 miles) over single-mode fiber optic cables. It operates at a wavelength of 1550 nm and uses the digital optical monitoring (DOM) feature to provide real-time monitoring of transceiver parameters such as temperature, optical power levels, and voltage. This transceiver module is hot-swappable, meaning it can be inserted or removed from a compatible network device without powering down the system. It is commonly used in enterprise networks, data centers, and service provider networks to enable high-speed and long-distance connectivity.
