CWDM OMUX in a point-to-point application

Point-to-Point (PTP) optical networks carry data directly between two end points without branching out to other points or nodes. PTP connections (Figure 9) are made between mux/demuxs at each end. PTP connections transport many gigabits of data from one location to another, such as linking two data centers to become one virtual site, mirroring two sites for disaster recovery, or providing a large amount of bandwidth between two buildings. The key advantage of a PTP topology is the ability to deliver maximum bandwidth over a minimum amount of fiber.

Each CWDM OMUX supports one network backbone connection and four or eight connections to CWDM GBICs in the switch. Typically, two CWDM OMUXs are installed in a chassis. The CWDM OMUX on the left is called the east path and the CWDM OMUX on the right is called the west path.
