TNF2LQM,03021FAT,Huawei OSN 1800 Optical Transponder LQM Board

Huawei OSN 1800 Optical Transponder LQM Board TNF2LQM 03020LYK Overview

TNF2LQM: 4 x Multi-rate Ports Wavelength Conversion Board

The available hardware versions for the LQM are TNF1 and TNF2.

The LQM can be used in two different application scenarios: convergence of Any service signals and regeneration of OTU1 optical signals.

The LQM board consists of the client-side optical module or client-side electrical module, the WDM-side optical module, the service en/de-capsulation and processing module, the clock module, the variable optical attenuator, the communication module, and the power supply module. The variable optical attenuator is optional. If you need this module, contact Huawei.

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

Transmit direction

The client-side optical module receives optical signals from client equipment through the RX1-RX4 ports, and performs O/E conversion.

The client-side electrical module receives electrical signals from client equipment through the RX1-RX4 ports, and performs level conversion.

After conversion, the four channels of electrical signals are sent to the service en/de-capsulation and processing module. The module performs processes such as multiplexing, clock generating and frame processing. Then, the module outputs a channel of OTU1 signals.

The OTU1 signals are sent to the WDM-side optical module. After performing E/O conversion, the module sends out the G.694.1-compliant 2.67 Gbit/s optical signals at DWDM standard wavelengths or the G.694.2-compliant 2.67 Gbit/s optical signals at CWDM standard wavelengths. The optical signals are output through the OUT1 and OUT2 optical ports.

Receive direction

The WDM-side optical module receives the G.694.1-compliant 2.67 Gbit/s optical signals at DWDM standard wavelengths or the G.694.2-compliant 2.67 Gbit/s optical signals at CWDM standard wavelengths 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 four channels of electrical signals at any rate.

The client-side optical module performs E/O conversion of the optical signals, and the client-side electrical module performs level conversion of the electrical signals, and then outputs four channels of client-side signals through the TX1-TX4 ports.

(Only the TX1/RX1 port on the TNF1LQM board supports; Only the TX1/RX1 and TX2/RX2 ports on the TNF2LQM board support.) NOTE: FC100, FC200, FICON, and FICON EXPRESS services that the TNF1LQM receives can be configured as sliced services. The "SDI" is also called the "SD-SDI" according to SMPTE 259M standard. It is recommended that F2LQM boards transmit and receive CPRI option2 services in ODU0 non-convergence mode, and CPRI option3 services in ODU1 non-convergence mode.
FEC mode	Supports forward error correction (FEC) that complies with ITU-T G.709.
Ethernet service mapping mode	TNF1LQM: Supports encapsulation of GE services in GFP-F (ITU-T G.7041) (displayed as GE on the NMS) and GFP-T (ITU-T G.7041) modes.
