Alcatel-Lucent 3AL34292AAAE legacy SDH/PDH transmission Optical Transmission Module

The Alcatel-Lucent 3AL34292AAAE is an S-4.1 STM-4 short-haul optical aggregate interface card, fitted with an FC/PC fibre connector, designed for Alcatel-Lucent’s legacy SDH transmission shelves. The S-4.1 designation marks this as a short-haul optical variant operating at the STM-4 rate (622 Mbit/s), suited to aggregate links between sites that are close enough not to require the extended optical budget of a long-haul (L-4.x) card. It fits into the aggregate slot of a compatible Alcatel-Lucent SDH shelf, carrying multiplexed tributary traffic as the shelf’s optical line-side interface, and its FC/PC connector terminates directly to standard single-mode fibre patch leads. As a field-replaceable plug-in module, it lets maintenance engineers restore short-haul aggregate connectivity on an in-service ring without disrupting the rest of the shelf. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy SDH optical spares including this aggregate card.
