Provision Optical Add/Drop Cards

This chapter describes optical add/drop cards used in Cisco ONS 15454 dense wavelength division multiplexing (DWDM) networks. For card safety and compliance information, refer to the Regulatory Compliance and Safety Information for Cisco CPT and Cisco ONS Platforms 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.

Chapter topics include:

9.1 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 Chapter10, “Provision Reconfigurable Optical Add/Drop Cards”

The AD-1C-xx.x, AD-2C-xx.x, AD-4C-xx.x, AD-1B-xx.x, and AD-4B-xx.x cards have different input and output optical channel signals depending on the interface card where the input signal originates from. The input interface cards have been grouped in classes listed in Table 9-3 . The subsequent tables list the optical performances and output power of each interface class.

9.1.4 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 9-7 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 B, “Hardware Specifications,” for more details.

For information about safety labels, see the “Class 1M Laser Product Cards” section.

9.3 AD-1C-xx.x Card

Note For AD-1C-xx.x card specifications, see the “AD-1C-xx.x Card Specifications” section in the Hardware Specifications document.

The 1-Channel OADM (AD-1C-xx.fx) 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.

Note For AD-2C-xx.x card specifications, see the “AD-2C-xx.x Card Specifications” section in theHardware Specifications document.

The 2-Channel OADM (AD-2C-xx.x) card passively adds or drops two adjacent 100-GHz channels within the same band. Sixteen versions of this card—each designed for use with one pair of wavelengths—are used in the ONS 15454 DWDM system. The card bidirectionally adds and drops in two different sections on the same card to manage signal flow in both directions. Each version of the card has a different part number.

The AD-2C-xx.x has the following features:

  • Passive cascade of interferential filters perform the channel add and drop functions.
  • Two software-controlled VOAs in the add section, one for each add port, regulate the optical power of inserted channels.
  • Software-controlled VOAs regulate insertion loss on express channels.
  • VOA settings and functions, photodiode detection, and alarm thresholds are internally controlled.
  • Virtual photodiodes (firmware calculation of port optical power) at the common DWDM output and input ports are monitored within the software.

9.6 AD-1B-xx.x Card

(Cisco ONS 15454 only)

Note For AD-1B-xx.x card specifications, see the “AD-1B-xx.x Card Specifications” section in the Hardware Specifications document.

The 1-Band OADM (AD-1B-xx.x) card passively adds or drops a single band of four adjacent 100-GHz-spaced channels. Eight versions of this card with eight different part numbers—each version designed for use with one band of wavelengths—are used in the ONS 15454 DWDM system. The card bidirectionally adds and drops in two different sections on the same card to manage signal flow in both directions. This card can be used when there is asymmetric adding and dropping on each side (east or west) of the node; a band can be added or dropped on one side but not on the other.

The AD-1B xx.x can be installed in Slots 1 to 6 and 12 to17 and has the following features:

  • Passive cascaded interferential filters perform the channel add and drop functions.
  • Two software-controlled VOAs regulate the optical power flowing in the express and drop OADM paths (drop section).
  • Output power of the dropped band is set by changing the attenuation of the VOA drop.
  • The VOA express is used to regulate the insertion loss of the express path.
  • VOA settings and functions, photodiode detection, and alarm thresholds are internally controlled.
  • Virtual photodiode (firmware calculation of port optical power) at the common DWDM output are monitored within the software.
