Cisco CPAK-100G-CWDM4

The Cisco CPAK-100G-CWDM4 is a transceiver module designed for high-speed data transmission over optical fiber networks. It is specifically designed to support 100 Gigabit Ethernet (100GbE) connections. The "CPAK" in the name stands for Cisco Pluggable Advanced Optics, which refers to the form factor of the transceiver module. It is a compact and hot-swappable module that can be easily inserted into compatible networking devices. The "100G" indicates that the module supports data rates of up to 100 Gigabits per second, making it suitable for high-bandwidth applications. The "CWDM4" refers to the type of optical technology used by the module. CWDM stands for Coarse Wavelength Division Multiplexing, which allows multiple optical signals to be transmitted simultaneously over a single fiber by using different wavelengths of light. The "4" indicates that the module supports four different wavelengths. Overall, the Cisco CPAK-100G-CWDM4 is a high-performance transceiver module used in data centers and telecommunications networks to enable fast and reliable data transmission over long distances.
