Description:
The Nortel NT0H01LB is an optical channel transceiver module used in Nortel optical transport equipment (such as Optical Metro/Optera 5200 series). This module is part of the NT0H01xx series, which provides OC-LD / optical channel line cards operating around 1.25 Gb/s (OC-3/STM-1 class) signals. The suffix “LB” indicates this specific wavelength and channel assignment within the NT0H01 series.
NT0H01xx modules are deployed as individual optical channel cards in a larger transport chassis where they terminate or originate one optical channel at standardized wavelengths in the 1530–1600 nm range. These cards interface between the fiber network and the transport system’s backplane.
