In most cases, the channels for these cards are either numbered (for example, 1to 32 or 1 to 40) or delimited (odd or even). Client interfaces must comply with these channelassignments to be compatible with the ONS 15454 system.Table 5-6 lists the channel IDs and wavelengths assigned to the C-band DWDM channels.NoteIn some cases, a card uses only one of the bands (C band or L band) and some or all of the channels listedin a band. Also, some cards use channels on the 100-GHz ITU grid while others use channels on the50-GHz ITU grid. See the specific card description or Appendix A, “Hardware Specifications” for moredetails.Table 5-6DWDM Channel Allocation Plan (C 0.11613195.401534.25054193.351550.517Cisco ONS 15454 DWDM Reference Manual, R8.578-18343-025-5

The faceplatesof the cards are clearly labeled with warnings about the laser radiation levels. You must understand allwarning labels before working on these cards.5.2.1 Class 1 Laser Product LabelsThe 32MUX-O card has a Class 1 laser. The labels that appear on the card are described in the followingsections.5.2.1.1 Class 1 Laser Product LabelThe Class 1 Laser Product label is shown in Figure 5-1.Class 1 Laser Product LabelCLASS 1 LASER PRODUCT145952Figure 5-1Class 1 lasers are products whose irradiance does not exceed the Maximum Permissible Exposure (MPE)value. Therefore, for Class 1 laser products the output power is below the level at which it is believedeye damage will occur. Exposure to the beam of a Class 1 laser will not result in eye injury and maytherefore be considered safe. However, some Class 1 laser products may contain laser systems of a higherclass but there are adequate engineering control measures to ensure that access to the beam is notreasonably likely. Anyone who dismantles a Class 1 laser product that contains a higher Class lasersystem is potentially at risk of exposure to a hazardous laser beam5.2.1.2 Hazard Level 1 LabelThe Hazard Level 1 label is shown in Figure 5-2.Cisco ONS 15454 DWDM Reference Manual, R8.55-878-18343-02

Some optical input and output ports are monitored by means of photodiodesimplemented both for power control and for safety purposes. An internal control manages VOA settingsand functionality as well as photodiode detection and alarm thresholds. The power at the main outputCisco ONS 15454 DWDM Reference Manual, R8.55-2278-18343-02

A virtual photodiode is implementedin the firmware of the plug-in module. This firmware calculates the power on a port, summing themeasured values from all single channel ports (and applying the proper path insertion loss) and thenproviding the TCC2/TCC2P card with the obtained value.5.5.1 Wavelength PairsTable 5-13 shows the band IDs and the add/drop channel IDs for the 4MD-xx.x card.Table 5-134MD-xx.x Channel SetsBand IDAdd/Drop Channel IDsBand 30.3 (A)30.3, 31.2, 31.9, 32.6Band 34.2 (B)34.2, 35.0, 35.8, 36.6Band 38.1 (C)38.1, 38.9, 39.7, 40.5Band 42.1 (D)42.1, 42.9, 43.7, 44.5Band 46.1 (E)46.1, 46.9, 47.7, 48.5Band 50.1 (F)50.1, 50.9, 51.7, 52.5Band 54.1 (G)54.1, 54.9, 55.7, 56.5Band 58.1 (H)58.1, 58.9, 59.7, 60.65.5.2 Power MonitoringPhysical photodiodes P1 through P8 a
