Precautions for MCA connections in the engineering design

2

The MCA board is the spectrum analyzer board with four or eight channels. It supports the functions of spectrum analysis, optical power detection, and APE. The precautions for its physical connections are as follows:

1. At an OTM or OADM site, IN1 connects to the east transmit end, IN2 connects to the east receive end, IN3 connects to the west transmit end, and IN4 connects to the west receive end.
2. At a ROADM site, the MCA board preferentially connects to the OA port. IN1 connects to the east transmit end, IN2 connects to the east receive end, IN3 connects to the west transmit end, and IN4 connects to the west receive end. It is not recommended that the MCA board be configured at the MON ports on boards that implement the ROADM function, because the port provides only the optical power detection function but not OSNR and wavelength detection.
3. For an ASON, the MCA board needs to be configured on the transmit and receive ends at the ROADM site. The local dimension is configured at the transmit end.
4. The MCA board does not support the OSN 1800 product.
5. The MCA board cannot be configured for the MON ports of the M40, D40, and V40 boards.

Precautions for physical connections of the MCA board during the project design
Question: What are the precautions for physical connections of the MCA board in project design? Analysis: None Root cause: MCA is a 4- or 8-channel spectrum analyzer that supports functions and features such as optical spectrum analysis, optical power detection, and APE. Pay attention to the following for the physical connections: 1. For an OTM or OADM site, connect the IN1 port to the east transmit port, IN2 to the east receive port, IN3 to the west transmit port, and IN4 to the west receive port. 2. For a ROADM site, preferentially connect the MCA board to the OA ports. Connect the IN1 port to the east transmit port, IN2 to the east receive port, IN3 to the west transmit port, and IN4 to the west receive port. Do not connect the MCA boards to the MON ports of boards that can implement the ROADM function. These MON ports provide only the function of optical power detection rather than OSNR and wavelength detection functions. 3. For an ASON network, the MCA board needs to be configured at both the transmit and receive ends of a ROADM site. In addition, the MCA board needs to be configured at the local transmit end. 4. The MCA board cannot be configured in the OSN 1800. 5. The MCA board cannot be configured on the MON ports of the M40, D40, and V40 boards. Answer: None

Whether MR8V can be connected to MCA to measure the line flatness
MR8V does not provide any MON port and therefore cannot be connected to the MCA board to measure the line flatness. To detect the line flatness, you can connect the MCA board to the MON port of the OA board adjacent to the MR8V board in the upstream direction.

What precautions do I need to pay attention to when connecting camera cables?
The precautions are as follows: In outdoor installation, a lightning arrester must be installed and the lightning rod must be grounded. The heavy current and light current cables must be separately laid. The distance between the heavy current cables and the light current cables must be greater than or equal to 5 cm. When connecting cables to the device, do not connect heavy current cables to the light current interfaces to avoid device damage. Use PVC insulation tape and waterproof tape to get all pigtails insulated and waterproofed to prevent short circuit and water leakage.

MCA functions
The MCA board is an optical spectrum analyzer board that is used to analyze the optical spectrum of optical signals. The MCA board analyzes the optical spectrum of the input optical signals, and transmits the analyzed and converted data to the control and communication module through the data interface. The control and communication module then reports the data to the SCC board and the NMS. The NMS then displays the final spectrum analysis results.
