The Cisco SFP-10G-LR-S supports 10 km over Single-mode fiber (SMF), using Duplex LC/PC connectors. Confirm the fiber grade and the optical budget of the link before ordering.
The Cisco SFP-10G-LR-S uses Duplex LC/PC. Standard duplex LC/PC patch cords are used for transmit and receive.
The SFP-10G-LR-S reaches 10 km over Single-mode fiber (SMF), while the SFP-10G-SR reaches — over . Pick the shortest reach that covers the link distance — going longer than needed costs more and adds optical budget margin you will not use.
