CIENA NTK539UB is a 100G WaveLogic 3 (WL3) optical transponder module with an integrated EDFA, designed for C-band DWDM long-haul transport. It is specified as a 100G EDC100G WL3 OCLD LH 1XOTU4 C-BAND CIRCUIT PACK, delivering a single OTU4 client with a C-band DWDM interface. Intended for use in Ciena’s 6500 Packet-Optical Platform and compatible transponder slots, the NTK539UB combines WL3 line functionality with C-Band DWDM and an EDFA to support high-capacity 100G links. Typical deployments include backbone or metro backhaul links requiring robust, long-haul 100G capacity across C-band wavelengths.
