Alcatel-Lucent 3AL94452EAAB09 TRBC1111 Transceiver Board

The Alcatel-Lucent 3AL94452EAAB09 TRBC1111 is a compact transceiver board engineered for flexible optical interface connectivity in the 1650 Synchronous Multiplexer - Compact (1650SM-C) and 1660 Synchronous Multiplexer (1660SM) platforms for SDH/SONET network architectures. This module serves as a universal host card for Small Form-factor Pluggable (SFP) optical transceivers, providing the electrical interface to the shelf backplane and the physical cage for various optical modules. The TRBC1111 card supports a wide range of data rates and protocols depending on the installed SFP, including STM-1/OC-3, STM-4/OC-12, STM-16/OC-48, Gigabit Ethernet, and Fast Ethernet, enabling multi-service aggregation in metro access and enterprise deployments. The board implements comprehensive signal conditioning, clock and data recovery (CDR), and serialization/deserialization (SERDES) functions to ensure signal integrity between the backplane and the optical module. Advanced features include hot-swappable SFP cages for non-disruptive module replacement, digital diagnostic monitoring (DDM) interface via I²C bus for real-time monitoring of optical power, temperature, laser bias current, and supply voltage, and comprehensive alarm indication for loss of signal (LOS) and transmitter fault conditions. The module integrates with the shelf's control plane for automated inventory detection of installed SFPs, configuration provisioning, and performance monitoring through the element management system. Management interfaces include standard I²C communication with the shelf controller for data retrieval and status reporting. Power is supplied via the shelf backplane with integrated regulation and protection circuits. 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. The TRBC1111 is validated for deployment in Alcatel-Lucent compact transport platforms and ensures compliance with ITU-T G.783, G.957, and SFF-8472 standards for optical interface management and interoperability.
