Connecting to the Network
Use the Network Port for backbone connectivity. The mux/demux
modules have one network port, which alternatively may be connected
to an expansion port (see below).
The OADM modules provide two network ports for connectivity to the
east and west. Connect the singlemode fiber from the west backbone to
the module’s WEST Network Port, and connect the singlemode cable
from the east backbone to the module’s EAST Network Port.
When making network connections, Metrobility recommends low
water peak ITU G.652.C-compliant singlemode fiber, such as Corning
®
SMF-28e
™
, which ensures low attenuation at the water peak (1383 nm).
Adding Channels Through the Expansion Port
By cascading through the expansion port, the four-channel mux/demux
modules can be configured to support up to 16 different channels over
the network. An example of how to configure two modules is shown
below.

Module 2
Module 1
After connecting to the local interfaces (channels 1-8), connect the
Network Port transmitter (TX) on Module 1 to the Expansion Port
receiver (RX) on Module 2. This connection is shown as a dashed blue
line in the diagram above. Connect Module 1’s Network Port receiver
to the Expansion Port’s transmitter (solid blue line).
In the illustration, the connection of the two modules via the expansion
port results in the transport of 12 wavelengths (channels 1-12) to the
network backbone. This is shown in green.
Refer to Expansion Port for more information.
