About This Part
The Alcatel 3AL91790AA is a critical optical interface module specifically engineered for integration within the Alcatel 1660 SM (Synchronous Multiplexer) product family. This module serves as a vital component for establishing high-speed optical data links, enabling robust and reliable network connectivity. Adhering to the S-1.1 optical interface standard, it is designed for short-haul applications, typically supporting STM-1 (Synchronous Transport Module Level 1) data rates of 155.52 Mbps. The module operates at a nominal wavelength of 1310 nm and is equipped with industry-standard LC connectors, ensuring compatibility and ease of deployment within existing fiber optic infrastructures. Its primary function is to convert electrical signals into optical signals for transmission over single-mode fiber and vice-versa, facilitating efficient data flow across metropolitan and access networks. This hot-swappable module ensures minimal service disruption during installation or maintenance, contributing to the overall resilience and operational efficiency of the network. The Alcatel 3AL91790AA module is typically deployed in the line cards or optical interface slots of Alcatel 1660 SM platforms, which are widely utilized by telecommunications operators, internet service providers, and large enterprises globally. These platforms form the backbone of many synchronous digital hierarchy (SDH) networks, providing essential infrastructure for voice, data, and video transmission. The Part Number 3AL91790AA facilitates the aggregation and transport of various traffic types over optical fiber, supporting applications such as leased lines, mobile backhaul, and inter-exchange carrier connectivity. Its robust design and adherence to established optical standards ensure seamless integration into mission-critical network environments. By providing a reliable and standardized optical interface, this module helps network operators solve challenges related to expanding network capacity, extending geographical reach, and ensuring the quality of service for their subscribers. It is often used in scenarios where existing Alcatel 1660 SM infrastructure requires maintenance, expansion, or the replacement of aging or faulty optical components to maintain network integrity and performance.
