Cisco CFP-40G-LR4

The Cisco CFP-40G-LR4 is a hot-pluggable transceiver module designed for high-speed data transmission over single-mode fiber optic cables. It is part of the Cisco 40 Gigabit Ethernet (40GbE) transceiver family and operates at a data rate of 40 Gbps. The "LR4" in the name stands for "Long Reach 4," indicating that it is capable of transmitting data over long distances. The module uses wavelength division multiplexing (WDM) technology to transmit and receive four different wavelengths simultaneously, each carrying 10 Gbps of data. This allows for a total aggregated data rate of 40 Gbps. The CFP-40G-LR4 is typically used in data center and telecommunications environments where high-speed and long-distance connectivity is required. It is compatible with various Cisco networking devices and provides reliable and high-performance connectivity for applications such as data center interconnects, metro networks, and long-haul transmission.
