Figure 5-10 Shock Hazard Label
This label alerts personnel to electrical hazard within the card. The potential of shock hazard exists when
removing adjacent cards during maintenance, and touching exposed electrical circuitry on the card itself.
5.3 32MUX-O Card
Note See the “A.6.1 32MUX-O Card Specifications” section on page A-19 for hardware specifications.
The 32-Channel Multiplexer (32MUX-O) card multiplexes 32 100-GHz-spaced channels identified in
the channel plan. The 32MUX-O card takes up two slots in an ONS 15454 and can be installed in
Slots 1 to 5 and 12 to 16.
The 32MUX-O features include:
• Arrayed waveguide grating (AWG) device that enables full multiplexing functions for the channels.
• Each single-channel port is equipped with VOAs for automatic optical power regulation prior to
multiplexing. In the case of electrical power failure, the VOA is set to its maximum attenuation for
safety purposes. A manual VOA setting is also available.
• Each single-channel port is monitored using a photodiode to enable automatic power regulation.
An additional optical monitoring port with 1:99 splitting ratio is available.
Figure 5-11 shows the 32MUX-O faceplate.
