Description
TNS7N404 overview
TNS7N404 supports 4*100Gbit/s Universal Line Service Processing Board, applied to Huawei OptiX OSN 9800.
The TNS7N404 board is a hybrid line board and supports a mixture of OTN, SDH services. The TNS7N404 board processes and converts the received service signals into two OTU4 signals.
The TNS7N404 board processes and converts the received service signals into four OTU4 signals. The OTU4 signals are carried over ITU-T G.694.1-compliant DWDM wavelengths.
It uses coherent receiving technologies and applies to coherent systems.
Variants
The TNS7N404 board has two variants: TNS7N404C01 and TNS7N404C06. The two variants are interchangeable.
