Huawei OptiXtrans E6600 8 Port Optical Transponder Unit TMB1ELOM Overview

TMB1ELOM: Enhanced 8 x Multi-rate Ports Wavelength Conversion Board

The TMB1ELOM board consists of the client-side optical module, the WDM-side optical module, the service en/de-capsulation and processing module, the clock processing module, the variable optical attenuator, the communication module, and the power supply module. The variable optical attenuator is optional

In the signal flow of the TMB1ELOM board, the transmit and the receive directions are defined. The transmit direction is defined as the direction from the client side of the B1ELOM to the WDM side of the B1ELOM, and the receive direction is defined as the reverse direction.

Transmit direction

The client-side optical module receives optical signals from client side equipment through the RX1 - RX8 optical ports, and performs O/E conversion.

After conversion, the eight channels of electrical signals are sent to the service en/decapsulation and processing module. The module performs processes such as multiplexing, clock generating and frame processing. Then, the module outputs two channel of OTU2 or OTU2e electrical signals.

The OTU2 or OTU2e electrical signals are sent to the WDM-side optical module. After performing E/O conversion, the module sends out the ITU-T G.694.1-compliant optical signals at DWDM standard wavelengths or the ITU-T G.694.2-compliant optical signals at CWDM standard wavelengths OTU2/OTU2e optical signals. The optical signals are output through the OUT1 and OUT2 optical ports.

Receive direction

The WDM-side optical module receives OTU2/OTU2e optical signals carried over an ITU-T G.694.1-compliant DWDM wavelength or ITU-T G.694.2-compliant CWDM wavelength from the WDM side through the IN1 and IN2 optical ports. Then, the module performs O/E conversion.

After O/E conversion, the signals are sent to the service en/de-capsulation and processing module. The module performs processes such as decapsulation, clock recovery and demultiplexing. Then, the module outputs eight channels of electrical signals at any rate.

The client-side optical module performs E/O conversion and the client-side electrical module performs level conversion of the eight channels of electrical signals, and then outputs eight channels of client-side optical signals and electrical signals through the TX1 - TX8 optical ports.
