100G DWDM Transponder (CFP2) – enabling reliable wavelength conversion and long-distance optical transmission in DWDM fiber networks. The card transforms 100G Ethernet customer traffic into wavelength division multiplexing (WDM) optical wavelengths to easily plug into metro and long-haul WDM systems.
The transponder also achieves high-density DWDM system stability performance by employing CFP2-DCO coherent optical technology with PDM-QPSK modulation. It supports tunable wavelengths across the C-band spectrum for added flexibility when deploying high-speed optical links.
It is commonly used for long-haul optical backbone networks, metro DWDM transport systems and data center interconnect (DCI) infrastructures.
100G CFP2 DWDM transponder module supports service conversion between client-side Ethernet and DWDM optical wavelengths with dedicated interfaces.
Client Side
