Product Overview

The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) offers enhanced optical amplifiers for extending the reach of a metro, regional, or long-haul network. The optical amplifier cards are part of the Cisco ONS 15454 MSTP intelligent dense wavelength-division multiplexing (DWDM) architecture engineered to reduce DWDM complexity and speed the deployment of next-generation networking solutions.

The Cisco ONS 15454 Enhanced C-Band 96 Channel Amplifier card (Figure 1) is a plug-in module that takes advantage of the proven Cisco ONS 15454 carrier-class features. It delivers the reach and optical performances to support a single DWDM channel all the way to 96 channels today, to meet the requirements of service provider and enterprise networks. Table 1 outlines the enhanced C-band optical amplifier plug-in card types available for the Cisco ONS 15454 MSTP with the applications they are designed to support.

Features and Benefits

The Cisco True Variable Gain Booster Amplifiers, with maximum 17- and 24-dB gain are high-power enhanced amplifiers suited for the needs of a next generation of optical networks. The coherent detection technology and a new modulation format like the PM-DQPSK modulation scheme employed in 40- and 100-Gbps transponder units of the recent high-capacity optical networks eliminate the need for dispersion compensation. The noise figure of these erbium-doped fiber amplifiers (EDFAs) is thus optimized by having a single amplification stage with no need for a lossy midstage access to provision dispersion-compensating units. Looking forward, the channel capacity is expected to grow beyond the current 80 channels to a 96-channel total. These amplifiers can also support the amplification of up to 96 channels in the C-band of the spectrum – 50-GHz-spaced ITU grid (wavelength range from 1528.77 to 1566.72 nm).

The 17- and 24-dB amplifiers take advantage of the latest in amplifier technology, variable optical attenuators, photo diodes, and extensive software to facilitate a high degree of automation for simplified operations. They feature a low-noise-gain block for C-band optical amplification requirements with an embedded gain-flattening filter. For flexibility of application support, the amplifiers support two modes of operation – constant gain and constant power – while also providing Amplified Spontaneous Emission (ASE) compensation in either modes. They also provide fast-transient suppression to respond quickly to network changes without adding impairments and degradation. Both cards allow a programmable tilt and possess a non-distorting low-frequency transfer function. Each card integrates software-controllable variable optical attenuators (VOAs) along with extensive optical monitoring with photo diodes, to provide nodal- and network-based automatic power-level management. Extensive optical safety algorithms provide user safety when operating the network. The optical amplifier cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational status at the card. Printed on each of the faceplates is an icon, an orange circle, which corresponds to shelf-slot icons located on the shelf assembly; it indicates the shelf slot where the cards can be inserted. The cards are supported by the integrated Cisco Transport Controller, a craft manager, which provides the user access for operations, administration, maintenance, and provisioning (OAM&P) for the system. Figure 2 depicts the functional block diagram of both amplifiers.

Deployment Application

Cisco True Variable Gain Booster Amplifier with maximum 17-dB gain (15454-OPT-EDFA-17)

You can use this flexible amplifier as a preamplifier or as a booster amplifier, providing a total output power of 20 dBm and maximum gain of 17 dB. It integrates an optical service channel splitter or combiner to allow the optical supervisory channel (OSC) to be sent to and received from the optical service channel module (OSCM) card or the OSC signal from the OSC pluggable associated with the Transport Node Controller (TNC) card.

Deployment locations include any site where high per-channel power is required to enter the fiber span.

Cisco True Variable Gain Booster Amplifier with maximum 24-dB gain (15454-OPT-EDFA-24)

You can use this flexible amplifier as a preamplifier or as a booster amplifier, providing a total output power of 20 dBm and maximum gain of 24 dB. It integrates an optical service channel splitter or combiner to allow the OSC to be sent to and received from the OSCM card or the OSC signal from the OSC pluggable associated with the Transport Node Controller (TNC) card.

Deployment locations include any site where high per-channel power is required to hit the fiber span.
