Optical Amplifier Cards
This chapter describes the optical amplifier 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.

4.1 Card Overview
This section provides summary and compatibility information for the optical amplifier cards.
Note
Optical amplifiers are used in amplified nodes (such as hub nodes), amplified OADM nodes, and line amplifier nodes. The six types of ONS 15454 DWDM amplifiers are:
•
•
•
•
•
•
Note
Optical amplifier card architecture includes an optical plug-in module with a controller that manages optical power, laser current, and temperature control loops. An amplifier also manages communication with the TCC2/TCC2P card and operation, administration, maintenance, and provisioning (OAM&P) functions such as provisioning, controls, and alarms.
Optical amplifiers have a linear power feature that enables them to remain in constant gain mode if the gain falls below 28 dB. However, for longer spans, you might have to manually place amplifiers in constant power mode.
If span loss degradation causes channel loss or reprovisioning while an amplifier is in constant power mode, the amplifier cannot dynamically adjust its output power to compensate for a decreased (or later increased) number of channels. In this way, constant power mode affects automatic power control (APC) requirements.

4.2 Class 1M Laser Safety Labels
This section explains the significance of the safety labels attached to the optical amplifier cards. The faceplates of the cards are clearly labeled with warnings about the laser radiation levels. You must understand all warning labels before working on these cards.
4.2.1 Class 1M Laser Product Label
Figure 4-1 shows the Class 1M Laser Product label. 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.
Figure 4-1 Class 1M Laser Product Label
4.2.2 Hazard Level 1M Label
Figure 4-2 shows the Hazard Level 1M label. The Hazard Level label warns users against exposure to laser radiation calculated in accordance with IEC60825-1 Ed.1.2.
Figure 4-2 Hazard Level Label
4.2.3 Laser Source Connector Label
Figure 4-3 shows the Laser Source Connector label. This label indicates that a laser source is present at the optical connector where the label appears.

4.2.4 FDA Statement Label
Figure 4-4 shows the FDA Statement label. This label represents compliance to FDA standards and a hazard-level classification in accordance with IEC60825-1 Am.2 or Ed.1.2.
Figure 4-4 FDA Statement Label
4.2.5 Shock Hazard Label
Figure 4-5 shows the Shock Hazard label. This label alerts you to an electrical hazard within the card. The potential for shock exists when you remove adjacent cards during maintenance or touch exposed electrical circuity on the card.
