Description:
The Cisco QSFP-40GE-LR4 is a transceiver module designed for use in 40 Gigabit Ethernet (40 Gbps) connections over single-mode fiber optic cable. It supports a maximum reach of 10 kilometers and utilizes four lasers with Coarse Wavelength Division Multiplexing (CWDM4) technology to transmit and receive data at different wavelengths within the 1310nm window. This allows for high-bandwidth data transmission over longer distances.
The QSFP-40GE-LR4 is a hot-swappable module, meaning it can be inserted and removed from a compatible switch or router without interrupting network operation. It also supports digital diagnostics monitoring, which allows for real-time monitoring of operational parameters such as temperature, laser bias current, and optical power output.
