The Cisco 15454-M-100G-ME-C Optical Transponder Module is a tunable 100G OTU-4 transponder that uses CP-DQPSK modulation across the full C-band. Its full C-band tunability enables flexible wavelength assignment for 100G OTU-4 transport in networks requiring adjustable optics. Also cataloged as CISCO 800-38038-01, this device corresponds to the 15454-M-100G-ME-C model.
