External optical amplifiers
Overview
The Alcatel-Lucent external optical amplifier provides service providers, system integrators, and network equipment manufacturers with one of the key technologies needed to build next generation DWDM and OADM networks. With the optical amplifier, operators enhance system performance while minimizing capital expenditures.
The optical amplifier can be configured to provide variable gain between 13 dB and 22 dB. This enables users to optimize optical transmission performance as needs grow. After gain setting is provisioned, the amplifier dynamically controls and maintains signal levels even as the number of amplified wavelengths change.
The amplifier features dynamic transient suppression and gain flattening across C-band to reduce the likelihood of data errors, channel outage, and signal degradation. In dynamic metro access networks or long-haul optical networks, these features allow service providers to provision and deliver reliable wavelength services to their end customers on demand.
The external optical amplifiers are available in front access and rear access versions.
The figure below shows the front access version of the external optical amplifier, and Figure 4-8, Optical amplifier (rear access) shows the rear access version of the external optical amplifier.

Interfaces
The optical amplifiers provide a 10/100 Mbps and an RS-232 port for operations and maintenance communications (similar to Alcatel-Lucent 1665 DMX). The optical amplifier continuously monitors its own electrical and optical performance. If operating parameters exceed user-specified thresholds, autonomous alarms are reported.
The optical amplifier may be managed by any of the following means:
