Overview of the OptiX OSN 7500
This chapter describes the positioning and application of the OptiX OSN 7500
intelligent optical switching system (the OptiX OSN 7500 for short) in the optical
transmission network.
The OptiX OSN 7500 is a piece of new generation equipment that Huawei develops
based on what the metropolitan area network (MAN) is like and its development trend
in the future. It is a piece of optical core switching (OCS) equipment and mainly used
on the service grooming node at the backbone layer of the MAN as an intelligent
optical switching platform. It features large switching capacity with a maximum of 240
Gbit/s higher order cross connection and 40 Gbit/s lower order cross connection.
In addition, the OptiX OSN 7500 provides intelligent features that are convenient and
flexible to implement. The intelligent features help the OptiX OSN 7500 to realize
dynamic switching and allocation of bandwidth, intelligent service routing and
end-to-end service configuration, and therefore bandwidth utilization is improved
effectively.
The OptiX OSN 7500 integrates synchronous digital hierarchy (SDH), plesiochronous
digital hierarchy (PDH), wavelength division multiplexing (WDM), Ethernet,
asynchronous transfer mode (ATM), storage area network (SAN) and digital video
broadcasting (DVB), thus capable of transmitting voice, data, SAN and video services
efficiently on the same platform.
Figure 1-1 shows the outer view of the OptiX OSN 7500.

As an intelligent optical core switching system with large capacity, the OptiX OSN
7500 is mainly used at the backbone layer of the MAN to groom and transmit various
services with different granules. It is used with the OptiX OSN 9500 and OptiX OSN
3500/2500/1500 to provide a complete MAN solution. Figure 1-2 shows how the OptiX
OSN 7500 is applied in the transmission network.

The OptiX OSN 7500 is gradually used on the core convergence node of large cities,
the optical core switching (OCS) of medium and small cities, and service grooming on
provincial trunks.
