Nokia (Alcatel‑Lucent) 8DG59561AB MVAC Multiple Variable Attenuator Card with WaveTracker for 1830 PSS-4, PSS-8, PSS-16, PSS-32

Nokia (Alcatel‑Lucent) 8DG59561AB MVAC Multiple Variable Attenuator Card

8DG59561AB MVAC is a photonic layer card for Nokia 1830 PSS optical transport platform. Equipped with 8 high-speed variable optical attenuators (VOA) and WaveTracker encoders, it handles optical power adjustment and alien wavelength tracking for TOADM and ROADM nodes.

Product Overview

Part Number: 8DG59561AB
Card Identifier: MVAC
Configuration: 8 high-speed VOA channels + WaveTracker wavelength encoders
Core Function: Optical power tuning, alien wavelength detection & tracking for TOADM / ROADM
Supported Platform: Nokia 1830 PSS‑4, PSS‑8, PSS‑16, PSS‑32

The MVAC card is a unidirectional photonic layer service blade designed for ROADM and TOADM architectures. It regulates the optical power of alien wavelengths passing through the node and tracks wavelength positions to maintain stable DWDM spectrum performance. It works with other photonic and amplifier cards within the 1830 PSS photonic layer. Please confirm shelf configuration and software release before ordering.

Key Features

• Multiple Variable Attenuator Card (MVAC) for 1830 PSS ROADM / TOADM systems
• 8 integrated high-speed variable optical attenuators for fine optical power adjustment
• WaveTracker encoders for alien wavelength identification and tracking
• Optimized for alien wavelength management in mesh DWDM networks
• Unidirectional photonic blade: alien wavelengths pass through MVAC on the add direction
• Hot-swappable design for in-service maintenance

Compatibility Notice

MVAC (8DG59561AB) is a dedicated photonic layer ROADM/TOADM blade, not an optical amplifier, power supply or service transponder. It is deployed to manage external alien wavelengths passing through the ROADM node. Supported on Nokia 1830 PSS‑4, PSS‑8, PSS‑16 and PSS‑32 platforms. Confirm shelf type and software release prior to deployment.
