Application

Because it is a type of optical protection unit, the QCP board implements intra-board 1+1 protection and client 1+1 protection.

For the position of the QCP board in the WDM system, see Figure 1 and Figure 2.

Figure 1 Position of the QCP board in the WDM system (intra-board 1+1 protection) 

 NOTE:

When being used for configuring intra-board 1+1 protection, the QCP board cannot be connected to an OTU board with the line rate of 2.5 Gbit/s.

For the application scenarios of intra-board 1+1 protection, see Introduction of the intra-board 1+1 protection in the Feature Description.

 NOTE:

For the application scenarios of client 1+1 protection, see Introduction of the client 1+1 protection in the Feature Description.

Functions and Features

The QCP board provides intra-board 1+1 protection and client 1+1 protection.

For detailed functions and features, refer to Table 1.

Table 1 Functions and features of the QCP board

Working Principle and Signal Flow

The QCP board contains the optical module, control and communication module, and power supply module.

Figure 1 shows the functional modules and signal flow of the QCP board.

Figure 1 Functional modules and signal flow of the QCP board 

Signal Flow

One QCP board supports the dual-feeding and selective receiving of four signals. It processes the four signals in the same way. The following describes the service flow of only one signal.

Transmit direction

The TI1 optical interface receives one channel of optical signals. After passing through the splitter, the signals are output to the working and the protection fibers (channels) through the TO11 and TO12 optical interfaces.

Receive direction

The signals in the working and the protection fibers (channels) are input through the RI11 and RI12 optical interfaces, and then are transmitted to the optical switch. The optical switch selects one from the two channels of signals based on the optical power of the signals. In this way, the selection of signals from the working and the protection channels is achieved. The selected optical signals are output through the RO1 optical interface.

The optical power detecting module detects the detection signals that are extracted from the working and protection signals, and reports the detection results to the control and communication module. The control and communication module compares the optical power of the two channels of optical signals, and controls the operation of the optical switch based on the optical power. In this way, the selection of signals from the working and the protection channels is achieved.

Module Function

Optical module

The optical module contains the signal dual-feeding part and signal selective receiving part.

Signal dual-feeding part

Divides the one channel of optical signals into two channels of the same power, and outputs them to the working and protection channels.

Signal selective receiving part: receives the optical signals from the working and protection channels. The optical power detection module detects and reports the optical power of two optical signals, and then the control and communication module controls and implements the selective receiving of optical signals from the working and protection channels.

Control and communication module

Controls board operations.

Controls the operations on each module of the board according to CPU instructions.

Collects information about alarms, performance events, working states, and voltages from functional modules on the board.

Communicates with the SCC board.

Power supply module

Converts the DC power supplied from the backplane into appropriate power required by each module on the board.

Front Panel

There are indicators and interfaces on the front panel of the QCP board.

Appearance of the Front Panel

Figure 1 shows the front panel of the QCP board.

Figure 1 Front panel of the QCP board 

Indicators

Four indicators are present on the front panel:

Board hardware status indicator (STAT) - triple-colored (red, green, yellow)

Service active status indicator (ACT) - dual-colored (red, green)

Board software status indicator (PROG) - dual-colored (red, green)

Service alarm indicator (SRV) - triple-colored (red, green, yellow)

For details about these indicators, see Board Indicators.

Interfaces

Table 1 lists the type and function of each interface.

Table 1 Types and functions of the interfaces on the QCP board

Laser Hazard Level

The laser hazard level of the board is HAZARD LEVEL 1, indicating that the maximum power launched by the board is less than 10 dBm (10 mW).

Valid Slots

One slot houses one QCP board.

Table 1 shows the valid slots for the TN11QCP board.

Table 1 Valid slots for the QCP board

 NOTE:

When a system control board is installed in slot IU2 of the OptiX OSN 9800 universal platform subrack subrack, the TN11QCP board cannot be installed in slot IU1.

Physical Ports Displayed on the NMS

This topic describes the interface information on the U2000.

Display of Optical Interfaces

The serial numbers of the optical interfaces on the front panel of the board displayed on the NM are listed in Table 1.

Table 1 Serial numbers of the interfaces of the QCP board displayed on the NM

 NOTE:

The port number displayed on the U2000 indicates a physical port pair, in which one port transmits signals and the other receives signals.
