Description of the optical ports on a transceiver OTU board

7

Question:
A transceiver OTU board provides two groups of optical ports: IN/OUT and Rx/Tx. The IN port inputs WDM-side signals and the OUT port outputs WDM-side signals. The Rx port inputs SDH-side signals and the Tx port outputs SDH-side signals. WDM side is also called line side, and SDH side is also called client side. In alarm parameters, the WDM-side IN/OUT port number is 1, and the SDH-side Rx/Tx port number is 2.
In some documents, the optical ports of a transceiver OTU board may be at the system side or line side. What is system side?

Answer:
System side is the former name of client side. Pay attention to distinguish the names.

Optical ports of the OTU board
The OTU board provides two groups of optical ports: IN/OUT and Rx/Tx. The IN and OUT ports correspond to WDM-side input and output, and the Rx and Tx ports correspond to SDH-side input and output. The WDM side is also called the line side; the SDH side is also called the client side. In the alarm parameters, 1 indicates the WDM-side transceiver optical port, and 2 indicates the SDH-side transceiver optical port. In some documents, the optical ports of the OTU board are classified into system-side and line-side ports. In the early period, the system side is also called the client side.

Whether the client-side optical port of the peer OTU board does not send or receive optical signals if the client-side optical port of the local OTU board does not with ALS enabled
According to the ALS principle, if the local OTU board does not receive any optical signal on its client side, the peer OTU board will not emit light on its client side.

Incorrect wavelength detected by the MCA/MS2 board for the OTU board of the Super WDM
The implementation of the Super WDM system is different from that of the common WDM system in the line modulation format of the transmit part. The Super WDM system uses the CRZ encoding format while the common WDM system uses the NRZ encoding format. These two modulation formats have different spectral widths and shapes in the corresponding frequency domains. For the NRZ encoding format, the width of �?0 dB spectrum is about 0.2 nm to 0.3 nm, and the spectral shape is shown in Figure 1. For the CRZ encoding format, the width of �?0 dB spectrum is about 0.64 nm, and the spectral shape is shown in Figure 2. The existing MCA board cannot select the spectral width of the wavelengths to be scanned, the adjacent wave crests in three wave crests of the LWFS board will be scanned. As a result, the wavelength offset will exceed the threshold.
