NTK552BAE5 is a Midstage Line Amplifier (MLA) circuit pack for Ciena’s 6500 Photonic Platform, designed to be installed in the MLA C-Band slot of an OM6500/6500 shelf to provide midstage amplification. It functions as a dual‑stage EDFA, combining a pre‑amplifier and a booster to boost optical signal strength within the MLA C‑Band assembly. This hardware circuit pack is specific to the MLA role in the OM6500 family, serving as a dedicated amplification module rather than a standalone shelf or transponder. It is used in Ciena’s 6500 photonic network architecture to maintain signal integrity across the midspan of optical paths in C‑band deployments.
