1 OverviewAbout This Chapter

This topic describes the OptiX OSN 500 equipment, and the network positioning and networkapplication of the OptiX OSN 500.

1.1 Introduction to the OptiX OSN 500The OptiX OSN 500 is new-generation optical transmission equipment, which is developed byHuawei for the access layer.1.2 Network ApplicationThe OptiX OSN 500 is used at the access layer of the transmission network. It can provideSTM-1/STM-4 optical interfaces and forms the entire equipment group with the other accesslayer equipment, thus optimizing the Huawei OptiX product series.1.3 Networking ApplicationExcept for the basic principles for planning a network, you need to plan a network according tothe NE type and networking mode supported by the OptiX OSN 500. The OptiX OSN 500 canform a network alone or with Huawei SDH equipment or third-party transmission equipment.

1.1 Introduction to the OptiX OSN 500The OptiX OSN 500 is new-generation optical transmission equipment, which is developed byHuawei for the access layer.Figure 1-1 shows the appearance of the OptiX OSN 500.

Figure 1-1 Appearance of the OptiX OSN 500 (48 V/60 V DC power input)

Figure 1-2 Appearance of the OptiX OSN 500 (110 V/220 V AC power input)

The OptiX OSN 500 is case-shaped equipment with a height of 1 U, and provides three slots,as shown in Figure 1-3.

Figure 1-3 Slot layoutSlot 3 Slot 4

Slot 2 (ISU)

The lower slot is an ISU slot, and the upper two slots are extended slots. The ISU slot houses afunctional board integrating the SCC unit, cross-connect unit, clock unit, tributary unit, line unit,and data transparent transmission unit. The ISU board is available in multiple types dependingon the functions and access capacity provided by the OptiX OSN 500. The extended slots supportthe line unit, tributary unit, and data unit. Table 1-1 provides the boards supported by the OptiXOSN 500.

In the Transmit DirectionThe overhead processing module inserts the overhead bytes into the electrical signals receivedfrom the cross-connect units and then transmits the signals to the E/O conversion module. TheE/O conversion module converts the received STM-1 electrical signals into STM-1 opticalsignals, which are then transmitted through fibers.

In the Receive DirectionThe O/E conversion module converts the received STM-1 optical signals into STM-1 electricalsignals and checks for the R_LOS alarm.The data clock recovery module recovers the clock signals, and transmits the STM-1 electricalsignals along with the clock signals to the overhead processing module. The overhead processingmodule checks for the R_LOF and R_OOF alarms.The overhead processing module also extracts overhead bytes from the received STM-1 signalsand transmits the signals to the cross-connect unit through the backplane.

Logical Control ModuleThe logical control module traces the clock signals and frame header signals that are receivedfrom the active or standby cross-connect board. This module controls the laser and passesthrough the orderwire and ECC bytes between the two optical interface boards that form anADM. This module also selects clock signals, frame header signals, and service signals fromthe active or standby cross-connect board.
