The 100G-4WDM-QSFP20KM is a cutting-edge 100 Gigabit Ethernet QSFP transceiver module that utilizes four-wavelength division multiplexing (4WDM) technology to transmit data over single-mode fiber optic cables up to 20 kilometers. This advanced WDM approach maximizes fiber utilization by multiplexing four separate wavelengths onto a single fiber, thereby increasing bandwidth capacity without additional cabling. It is ideally suited for metro and enterprise network applications requiring extended reach with high-speed data transfer. The module complies with IEEE standards for 100G Ethernet, ensuring interoperability and reliability across diverse network equipment. It features a hot-swappable design for easy installation and maintenance, minimizing network downtime. Additionally, the 100G-4WDM-QSFP20KM operates efficiently with low power consumption, making it an environmentally friendly and cost-effective choice for growing data center infrastructures. Its compact form factor allows for high-density deployment in modern switches and routers, supporting scalable network expansion while maintaining exceptional performance and signal quality.
