            Huawei OptiX OSN 1800 SDH Optical Interface Board TNF8SL16Q Overview
TNF8SL16Q: 4 x STM-16 processing board
The TNF8SL16Q can be used to receive and transmit four STM-16 optical signals. The SL16Q converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL16Q converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.
The TNF8SL16Q consists of an O/E conversion unit, an overhead processing unit, a logic control unit, and a clock unit.
The TNF8SL16Q Receives/Transmits 4 x STM-16 optical signals.
