6.3 AD-1C-xx.x Card
Figure 6-5 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.
6.3 AD-1C-xx.x Card
Note See the “A.8.1 AD-1C-xx.x Card Specifications” section on page A-38 for hardware specifications.
The 1-Channel OADM (AD-1C-xx.x) card passively adds or drops one of the 32 channels utilized within
the 100-GHz-spacing of the DWDM card system. Thirty-two versions of this card—each designed only
for use with one wavelength—are used in the ONS 15454 DWDM system. Each wavelength version of
the card has a different part number. The AD-1C-xx.x can be installed in Slots 1 to 6 and 12 to 17.
The AD-1C-xx.x has the following internal features:
• Two cascaded passive optical interferential filters perform the channel add and drop functions.
• One software-controlled variable optical attenuator (VOA) regulates the optical power of the
inserted channel.
• Software-controlled VOA regulates the insertion loss of the express optical path.
• VOA settings and functions, photodiode detection, and alarm thresholds, are internally controlled.
• Virtual photodiodes (firmware calculations of port optical power) at the common DWDM output and
input ports are monitored within the software.
Figure 6-6 shows the AD-1C-xx.x faceplate.
