OTS9100 User Manual 1-13
Module Quick Check
NOTE: Before installing the optical cables, clean the optical fiber connectors on both the cable
ends and the front panel connectors.
1. With proper in-line 15dB attenuator, connect a single mode optical cable between the Optical
OUT and Optical IN connectors on the Optics card.
CAUTION! Signal levels greater than 0 dBm may damage the Optical Input devices. Always
pad the input level to less than 0 dBm.
Always use 15dBm of attenuation when connecting the OTS9100 module transmit output to its
receive input. Failure to do so will damage the optical detector.
2. If the instrument is not already powered on, start the system as described in the Power On
and Software Initialization procedure of the previous section.
3. From the Menu Bar, click the System button; this opens a drop down menu. In the drop down
menu select Signal Standard then select Set to SONET.
4. Transmitter Setup
From the Menu Bar, click on View and select System View. The System View should
display an image with each card in position. Check this view to ensure that all the cards
loaded are visible. Blue lines spanning across the cards represent the correct cabling for the
configuration of cards loaded in the system. The System View window is meant to be used as
a reference for verifying cards and cabling a system. It does not provide a means to
determine live or dead cards.
5. Click the Setup Category bar in the Navigation window and select the OTS91T3 10Gb/s Tx+
#1 icon. The Setup Property Page associated with the selected icon should display.

8. Receiver Setup
In the Navigation window, keeping the Setup Category as the active category (always check
the Title Bar of the Setup Menu to ensure that it is associated with the correct device), select
the OTS91R2 10Gb/s Rx+ #1 icon and set the Receiver Threshold Offset level to 0 mV.
