The Cisco SFP-10G-LR-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 "LR" in the model name stands for "long reach," indicating that this transceiver is capable of transmitting data over long distances. The "S" at the end of the model name signifies that it is a Cisco original product. The SFP-10G-LR-S operates using a single-mode fiber optic cable and has a maximum reach of up to 10 kilometers (6.2 miles). It supports a wavelength of 1310 nanometers (nm) and provides a data transfer rate of 10 Gbps. This transceiver module is commonly used in enterprise networks, data centers, and telecommunications environments to connect switches, routers, and other networking devices over long distances.
