DWDM (Dense Wavelength Division Multiplexing) is a technology used in fiber optic networks to increase the capacity of existing fiber optic cables. It works by combining multiple optical signals into a single fiber optic cable, allowing for more data to be transmitted over a single connection. DWDM is used in a variety of applications, including telecommunications, data centers, and cloud computing. It is also used in long-distance networks, such as those connecting cities and countries. DWDM is a cost-effective way to increase the capacity of existing fiber optic networks, allowing for more data to be transmitted over a single connection. It is also more reliable than other technologies, as it is less susceptible to interference.
The Dell 0RP3GV Q28-100G-DWDM2-32 QSFP28 DWDM transceiver supports to multiple 100G links up to 80km over single-mode fiber (SMF) via an CS connector. PAM4 modulation technology allows for DWDM connectivity in a QSFP28 form factor on the 100G ITU DWD..
