Alcatel-Lucent 3AL34727BC legacy SDH/PDH transmission Optical Transmission Module

The Alcatel-Lucent 3AL34727BC is an optical aggregate interface card operating at the STM-16 rate (2.5 Gbit/s), part of the same 3AL34727 aggregate-card family as the SC/PC and FC-terminated variants used in Alcatel-Lucent’s legacy SDH transmission shelves. Like its siblings in the same part family, it fits into the aggregate slot of a compatible Alcatel-Lucent SDH shelf, carrying multiplexed tributary traffic as the shelf’s high-capacity optical line-side interface between network sites. The ‘BC’ variant code distinguishes this build from the AA and AC options in the same family, most likely reflecting a different connector or optical budget configuration suited to a particular site’s fibre plant. As a field-replaceable plug-in module, it lets maintenance engineers restore high-capacity 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.
