Application

Because it is a type of optical protection unit, the DCP board implements intra-board 1+1 protection , optical wavelength shared protection (OWSP protection) and client-side 1+1 protection.

For the position of the DCP board in the WDM system, see Figure 1, Figure 2 and Figure 3.Figure 1 Position of the DCP board in the WDM system (intra-board 1+1 protection) 

 NOTE:

When used for intra-board 1+1 protection, the DCP board does not support the 2.5 Gbit/s OTU.

For the application scenarios of intra-board 1+1 protection, see Introduction of the intra-board 1+1 protection in the Feature Description.Figure 2 Position of the DCP board in the WDM system (OWSP protection) 

Figure 3 Position of the DCP board in the WDM system (client-side 1+1 protection) 

 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 DCP board provides intra-board 1+1 protection , OWSP protection and client-side 1+1 protection.

For detailed functions and features, refer to Table 1.

Function and Feature Description
Basic function Provides intra-board 1+1 protection to protect the services of the OTU, which has no dual-fed and selective receiving function. Compared with the OLP, the DCP provides protection for two signals to implement 1+1 protection.Provides client-side 1+1 protection, using a working OTU and a protection OTU to protect the client-side services.Provides the OWSP protection, make use of two different channels to achieve the protection of one channel of service between all stations.
Protection mechanism Dual-fed and selective receiving. (At the transmit end, the protected signal is dually fed to the working and protection paths. At the receive end, the working or protection signal is selected if it has the higher power level.)
Optical-layer ASON Supported

Working Principle and Signal Flow

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

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

Signal Flow

One DCP board supports the dual-fed and selective receiving of two channels of optical signals. The DCP board processes the two channels of optical signals in the same way. This section describes the service flow of only one channel of optical signals.

  • Transmit directionThe 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 directionThe 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 moduleThe optical module consists of two signal dual-fed parts and two signal selection parts.
    • Signal dual-feeding partDivides 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 operations on the board.
    • Controls operations on each module of the board according to CPU instructions.
    • Collects information about alarms, performance events, working states and voltage detection from each functional module on the board.
    • Communicates with the system control and communication board.
  • Power supply moduleConverts the DC power supplied by the backplane into the power required by each module on the board.

Parameters Can Be Set or Queried by NMS

This section lists the board parameters that can be set or queried by using the NMS.

For parameters of the DCP, refer to Table 1.

Field Value Description
Optical Interface/Channel - Displays the position of the optical interface.
Optical Interface Name - Sets and queries the Optical Interface Name.An Optical Interface Name contains a maximum of 64 characters. Any characters are supported.
Input Power Loss Threshold (dBm) -35 to -10Default: -35 The Input Power Loss Threshold (dBm) parameter queries the threshold value of the input optical power, which can trigger a board to generate an optical power loss (MUT_LOS) alarm. When the actual input optical power is lower than this threshold value, the board reports the MUT_LOS alarm.
Initial Variance Value Between Primary and Secondary Input Power (dB) -10 to 10Default: 0 Specifies the initial difference between the input working and protection signal power levels of a board.See Initial Variance Value Between Primary and Secondary Input Power (dB) (WDM Interface) for more information.
Variance Threshold Between Primary and Secondary Input Optical Power (dB) 0, 3 to 8Default: 5 Specifies the difference threshold for the input working and protection signal power levels. When the difference between the input working and protection signal powers reaches a specific value close to this threshold, a signal fail (SF) condition has occurred. When the difference exceeds this threshold, a POWER_DIFF_OVER alarm is reported and protection switching is performed to select the signal with higher power, ensuring desired service performance.See Variance Threshold Between Primary and Secondary Input Power (dB) (WDM Interface) for more information.

DCP Specifications

Specifications include optical specifications, dimensions, weight, and power consumption.

 NOTE:Margins exist between the default input power low threshold and the receiver sensitivity and between the default input power high threshold and the overload point. These margins ensure that the system can report an input power low or high alarm before the actual input power reaches the receiver sensitivity or overload point.
