Optical Add/Drop Cards
This chapter describes optical add/drop cards used in Cisco ONS 15454 dense wavelength division multiplexing (DWDM) networks. For installation and card turn-up procedures, refer to the Cisco ONS 15454 DWDM Procedure Guide. For card safety and compliance information, refer to the Cisco Optical Transport Products Safety and Compliance Information document.
Note The cards described in this chapter are supported on the Cisco ONS 15454, Cisco ONS 15454 M6, Cisco ONS 15454 M2 platforms, unless noted otherwise.
Note Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI shelf assemblies.
8.1 Card Overview
The card overview section contains card overview, software compatibility, interface class, and channel allocation information for optical add/drop cards.
Note Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols. For a list of slots and symbols, see the "Card Slot Requirements" section in the Cisco ONS 15454 Hardware Installation Guide.
Optical add/drop cards are divided into two groups: band optical add/drop multiplexer (OADM) cards and channel OADM cards. Band OADM cards add and drop one or four bands of adjacent channels. The cards in this chapter, including the 4-Band OADM (AD-4B-xx.x) and the 1-Band OADM (AD-1B-xx.x) are utilized only in the C band. Channel OADM cards add and drop one, two, or four adjacent channels; they include the 4-Channel OADM (AD-4C-xx.x), the 2-Channel OADM (AD-2C-xx.x), and the 1-Channel OADM (AD-1C-xx.x).
Note For information about L band add and drop capability, see Chapter9, “Reconfigurable Optical Add/Drop Cards”

8.1.4 DWDM Card Channel Allocation Plan
ONS 15454 DWDM channel OADM and band OADM cards are designed for use with specific channels in the C band. In most cases, the channels for these cards are either numbered (for example, 1 to 32) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with the ONS 15454 system.
Table 8-7 lists the channel IDs and wavelengths assigned to the C-band DWDM channels.
Note In some cases, a card uses only some or all of the channels listed in a band. Also, some cards use channels on the 100-GHz ITU-T grid while others use channels on the 50-GHz ITU-T grid. See specific card descriptions in Appendix A, “Hardware Specifications,” for more details.

8.2 Class 1M Laser Product Safety Lasers
This section lists the safety labels attached to the AD-1C-xx.x, AD-2C-xx.x, AD-4c-xx.x, AD-1B-xx.x, and AD-4B-xx.xx cards.
8.2.1 Class 1M Laser Product Statement
The Class 1M Laser Product statement is shown in Figure 8-1.
Figure 8-1 Class 1M Laser Product Statement
Class 1M lasers are products that produce either a highly divergent beam or a large diameter beam. Therefore, only a small part of the whole laser beam can enter the eye. However, these laser products can be harmful to the eye if the beam is viewed using magnifying optical instruments.
8.2.2 Hazard Level 1M Label
The Hazard Level 1M label is shown in Figure 8-2.
The Hazard Level label warns users against exposure to laser radiation of Class 1 limits calculated in accordance with IEC60825-1 Ed.1.2. This label is displayed on the faceplate of the cards.
8.2.3 Laser Source Connector Label
The Laser Source Connector label is shown in Figure 8-3.
Figure 8-3 Laser Source Connector Label
This label indicates that a laser source is present at the optical connector where the label has been placed.
8.2.4 FDA Statement Label
The FDA Statement labels are shown in Figure 8-4 and Figure 8-5. These labels show compliance to FDA standards and that the hazard level classification is in accordance with IEC60825-1 Am.2 or Ed.1.2.
Figure 8-4 FDA Statement Label
Figure 8-5 FDA Statement Label
8.2.5 Shock Hazard Label
The Shock Hazard label is shown in Figure 8-6.
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.
