Huawei OSN 9800 LDX Board TN12LDX Overview

LDX: 2 x 10 Gbit/s wavelength conversion unit

Only one functional version of the LDX board is available, that is, TN12.

The TN12LDX board has one variant: TN12LDX02.

The LDX board is an optical transponder unit that converts two channels of 10 Gbit/s service signals into OTU2 or OTU2e signals and performs conversion between the 10 Gbit/s service signals and WDM signals that comply with ITU-T Recommendations.

The LDX board provides OTN interfaces and electrical supervisory channels (ESCs).

The LDX board consists of the client-side optical module, WDM-side optical module, signal processing module, control and communication module, and power supply module.

The transmit and the receive directions are defined in the signal flow of the LDX board. The transmit direction is defined as the direction from the client side of the LDX to the WDM side of the LDX. The receive direction is defined as the direction from the WDM side of the LDX to the client side of the LDX.

The RX1/TX1 and RX2/TX2 ports independently process signals. The RX1/TX1 port corresponds to the OUT1/IN1 port, and the RX2/TX2 port corresponds to the OUT2/IN2 port.

Transmit direction

The client-side optical module receives two channels of the optical signals from client equipment through the RX1/RX2 optical interface and performs O/E conversion.

After O/E conversion, the electrical signals are sent to the signal processing module. OTU2/OTU2e signals are sent to the client-side OTN processing module for performance monitoring. Other types of signals are sent to different encapsulation and mapping modules for encapsulation and mapping. In the end, operations such as the OTN framing and FEC encoding are performed. Finally, the module outputs two channels of OTU2 /OTU2e electrical signals.

The OTU2/OTU2e signals are sent to the WDM-side optical module. After E/O conversion, the module transmits OTU2/OTU2e optical signals at DWDM wavelengths that comply with ITU-T G.694.1 through the OUT1 and OUT2 optical interfaces.

Receive direction

The WDM-side optical module receives two channels of OTU2/OTU2e optical signals at DWDM wavelengths that comply with ITU-T G.694.1 through the IN1 and IN2 optical interfaces. Then, the module performs O/E conversion.

After O/E conversion, the OTU2/OTU2e signals are sent to the signal processing module. The module performs operations such as OTU2/OTU2e framing, FEC decoding, demapping, and decapsulation processing. Then, the module outputs two channels of OC-192, STM-64, 10GE LAN, 10GE WAN, or OTU2/OTU2e electrical signals.

The client-side optical module performs E/O conversion of OC-192, STM-64, 10GE LAN, 10GE WAN, or OTU2/OTU2e electrical signals, and then outputs client-side optical signals through the TX1 and TX2 optical interfaces.

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