SL91CQ1,CQ1,,Huawei OptiX RTN 980L IDU Boards

Huawei RTN 980L Board SL91CQ1 Overview

The functional version of CQ1 boards is SL91.

CQ1 boards apply to OptiX RTN 980L NEs to transparently transmit STM-1 services over Packet microwave networks. CQ1 boards receive/transmit only channelized STM-1 services.

A CQ1 board receives and transmits four channels of channelized STM-1 optical/electrical signals.

This section describes how the functional units of a CQ1 board process channelized STM-1 optical signals.

A CQ1 board has indicators and STM-1 ports on its front panel.

The CSHL can be inserted in slots 15 and 20. On the NMS, the CSHL is divided into three logical boards by function and each logical board has a logical slot.

The CQ1 board can be inserted in Slots 1 to 14, which have consistent logical slot numbers on the NMS.

STM-1 ports on CQ1 boards support multiple types of SFP modules.

This section describes the technical specifications of the CQ1, including STM-1 optical/electrical port specifications, mechanical specifications, and power consumption.
