Description
SSN1SL1A Overview
The SL1A is available in one functional version, namely, N1.
Through the board version replacement function, the N1SL1A can substitute for the N1SL1.
The SL1A is a line board. The SL1A can be used on the OptiX OSN equipment series to transmit and receive STM-1 optical signals. The SL1A converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SL1A converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.
The SL1A transmits and receives STM-1 optical signals, performs O/E conversion for the STM-1 optical signals, extracts and inserts overhead bytes, and generates alarm signals on the line.
The SL1A can be installed in slots 1-8, 11-18, and 26-31 in the subrack.
