Provisioning 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 ONS Products 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:

Card Overview

The card overview section contains card overview, software compatibility, and channel allocation information for optical add/drop cards.

Optical add/drop cards are divided into two groups:

  • Band optical add/drop multiplexer (OADM) cards

  • 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).

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 9-2 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.

AD-1B-xx.x and AD-4B-xx.x Cards

AD-1B-xx.x Card

The AD-1B-xx.x card has reached end of support.

(Cisco ONS 15454 only)

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 features of the AD-1B-xx.x card are listed in the section, "“Features of AD-1B-xx.x and AD-4B-xx.x Cards” section on page 9-7".

For more information about the AD-1B-xx.x card, see http://www.cisco.com/en/US/prod/collateral/optical/ps5724/ps2006/product_data_sheet09186a00801a5572.html.

AD-4B-xx.x Card

The AD-4B-xx.x card has reached end of support.

(Cisco ONS 15454 only)

The 4-Band OADM (AD-4B-xx.x) card passively adds or drops four bands of four adjacent 100-GHz-spaced channels. Two versions of this card with different part numbers—each version designed for use with one set of bands—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 features of the AD-4B-xx.x card are listed in the section, "“Features of AD-1B-xx.x and AD-4B-xx.x Cards” section on page 9-7".

Features of AD-1B-xx.x and AD-4B-xx.x Cards

The AD-1B-xx.x and AD-4B-xx.x cards have the following features:

  • Software-controlled VOAs regulate the optical power flowing in the OADM paths.

  • 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.

  • Software-monitored virtual photodiodes (firmware calculation of port optical power) at the common DWDM output and input ports.


    Note

    The AD-4B-xx.x card has only one virtual photodiode at the common DWDM output port.
