Alcatel-Lucent 3AL97795BA AD01 WLA 3CD Line Processing Unit

The Alcatel-Lucent 3AL97795BA AD01 WLA 3CD (Wavelength Lambda 3 Channel Dense) is a line processing unit engineered for high-capacity optical channel termination, wavelength division multiplexing, and transport in DWDM/OTN network platforms for metropolitan and long-haul telecommunications infrastructure. This module provides advanced optical channel functionality with support for dense wavelength division multiplexing (DWDM) applications in C-band spectrum. The WLA 3CD card implements comprehensive optical channel processing including wavelength conversion, 3R regeneration (re-amplification, re-shaping, re-timing), forward error correction (FEC) encoding/decoding per ITU-T G.709 and G.975 specifications, and optical performance monitoring for bit error rate (BER), optical signal-to-noise ratio (OSNR), chromatic dispersion, and polarization mode dispersion (PMD). The board features integrated optical transceiver functionality with laser drivers, photodiode receivers, and signal conditioning electronics supporting standardized DWDM grid spacing (100 GHz, 50 GHz, or 25 GHz) per ITU-T G.694.1 with configurable wavelengths for flexible network deployment. Advanced features include automatic power control (APC), wavelength stabilization with temperature compensation, hitless protection switching with sub-50ms switchover, automatic laser shutdown (ALS) for fiber break protection, and comprehensive digital diagnostic monitoring (DDM) for real-time visibility of optical power levels, temperature, bias current, and supply voltage. The module supports multiple client interfaces including STM-1/OC-3, STM-4/OC-12, STM-16/OC-48, Gigabit Ethernet, and 10 Gigabit Ethernet with automatic client signal detection and adaptation. Integration with the transport shelf backplane provides high-speed connectivity to cross-connect matrices, optical amplifier controllers, wavelength selective switches (WSS), reconfigurable optical add-drop multiplexers (ROADM), and system control processors for coordinated network operation. Management interfaces include I²C, MDIO, SNMP v3, TL1, NETCONF/YANG, and proprietary element management system protocols for integration with Alcatel-Lucent's 1350 OMS, NuWave EMS, and third-party network management systems, providing access to wavelength configuration, optical power levels, FEC statistics, performance monitoring data, alarm status, and diagnostic information. The WLA 3CD implements redundant protection architectures including 1+1 optical channel protection, client-side protection, and path protection switching with automatic revertive and non-revertive modes. Power is distributed via redundant −48 V DC feeds with integrated voltage regulation, current monitoring, and overcurrent protection. Environmental specifications comply with ETSI EN 300 019 Class 3.1 and NEBS GR-63 Level 3 standards, supporting continuous operation in controlled telecommunications facilities with ambient temperatures from 0 °C to +45 °C and relative humidity up to 95% non-condensing. The WLA 3CD is validated for deployment in Alcatel-Lucent 1650SM/1660SM/1670/1696MS/1830/1850 series optical transport platforms and ensures compliance with ITU-T G.709, G.798, G.872, G.694.1, G.698, G.959.1, G.783, G.825, IEEE 802.3, and Telcordia GR-253/GR-487 standards for optical line processing and carrier-grade DWDM/OTN network interoperability.
