Huawei OTN Service Board SL91SL1D02 Overview

The SL1D/SL1DA is a 2xSTM-1 optical interface board. It can also provide STM-1 electrical ports through SFP electrical modules. In addition to all functions of the SL1D board, the SL1DA board also supports K byte pass-through. The functional version of the SL1D/SL1DA board is SL91.

The SL1D/SL1DA board can be used by the OptiX RTN 950 to aggregate TDM services from a microwave network for transmission to an SDH network or by the OptiX RTN 950 to work with the SDH equipment for building an SDH network.

The SL1D/SL1DA board receives and transmits two channels of STM-1 optical or electrical signals.

On the front panel of the SL1D/SL1DA board, there are indicators, STM-1 ports, and labels.

The SL1D/SL1DA board provides two STM-1 ports.

Indicators visually communicate the operating status of the SL1D/SL1DA board.

The SL1D/SL1DA board can be inserted in any of slots 1 to 6. The logical slots for the board on the NMS are the same as the physical slots.

The type of the SFP module of the SL1D/SL1DA board can be identified by the board feature code in the bar code. A board feature code refers to the number next to the board name in a bar code.
