The Cisco QSFP-40G-LR4 is a transceiver module designed for use in high-speed data communication networks. It is part of the Cisco Quad Small Form-Factor Pluggable (QSFP) family of transceivers and supports data rates of up to 40 Gigabits per second (Gbps). The "LR4" in the product name stands for "Long Reach 4" and indicates that the module is capable of transmitting and receiving data over long distances. It uses four wavelengths of light (1310 nm) to achieve this, with each wavelength carrying a 10 Gbps data stream. The QSFP-40G-LR4 transceiver is commonly used in applications such as data centers, telecommunications networks, and high-performance computing environments. It provides a high-bandwidth and low-latency solution for connecting switches, routers, and other network devices over fiber optic cables.
