OptiX OSN 7500 Intelligent Optical Switching System. Technical Manual - part 3
3-14
The dimensions of the OptiX OSN 7500 subrack is 757 mm (H) x 497 mm (W) x 295
mm (D). A single empty subrack weighs 20 kg.
The OptiX OSN 7500 provides two-layer subracks, composed of processing board
area, interface board area, fan area, and fiber routing area, as shown in Figure 3-2.

This chapter introduces the board types of the OptiX OSN 7500, and the slots in which
they can be installed. It covers:
Board type
Installation slot
4.1 Type
The OptiX OSN 7500 consists of SDH interface unit, PDH interface unit, data service
(Ethernet/ATM/SAN/Video) interface unit, SDH cross-connect matrix unit (the core
part), synchronous timing unit, SCC unit, overhead processing unit, power input unit
and auxiliary interface unit. Figure 4-1 shows the system architecture of the OptiX
OSN 7500, and Figure 4-1 shows the boards and functions of each unit. For details,
refer to OptiX OSN 7500 Intelligent Optical Switching System Hardware Description
