Optical multiplexer 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. Point-to-Point connections (see the following figure) are made between
mux/demuxs at each end. Point-to-Point connections transport many gigabits of data from one
location to another to support applications, such as the linking of two data centers to become one
virtual site, the mirroring of two sites for disaster recovery, or the provision of a large amount of
bandwidth between two buildings. The key advantage of a Point-to-Point topology is the ability to
deliver maximum bandwidth over a minimum amount of fiber.
Each CWDM optical multiplexer/demultiplexer (OMUX) supports one network backbone connection
and four or eight connections to transceivers (SFPs/SFP+s). Typically, two OMUXs are installed in a
chassis. The OMUX on the left is called the east path, and the OMUX on the right is called the west
path.
