The CPF2-100G-LR2 is a Cisco-manufactured 100G optical transceiver designed for long-range (LR2) transmission. It supports data transmission rates of up to 100 Gbps and operates over single-mode fiber (SMF) with a maximum reach of 10 km. This module is used for high-performance networking, typically in data centers and telecommunication infrastructures, where high-speed and long-distance connectivity are essential. It uses an LC duplex connector and supports Digital Optical Monitoring (DOM) for real-time monitoring.
