Description:
The Nortel NT0H20DJ is a legacy optical transport and traffic interface module originally manufactured for Nortel’s Optical Metro family (such as OM5100/OM5200/Optical Metro 5000) used by carriers and service providers for high-speed fiber transport. It functions as an OC-48/STM-16 (≈2.5 Gbps) optical channel interface (OCI) traffic card operating at a 1310 nm wavelength over single-mode fiber (SMF), providing critical DWDM/CWDM optical link support and optical transport network layering.
