ALCATEL 1AB210830002 -Lucent 1626 Light Manager (1626 LM) DWDM optical line system Optical Transmission Module

The Alcatel-Lucent 1AB210830002 is a dispersion compensation module (DCM) for Alcatel-Lucent’s 1626 Light Manager (1626 LM) DWDM optical line system, documented in supplier catalogues as ‘DCM-5’ / ‘LL DCM 5 KM’. It compensates chromatic dispersion accumulated over single-mode C-band fibre spans, in this case sized for the shortest reach tier in the 1626 LM’s DCM range, roughly equivalent to 5km of standard SMF dispersion. Installed as a passive fibre-based module within the 1626 LM shelf or an associated optical line amplifier site, it works alongside the platform’s optical amplifiers and add/drop elements to keep DWDM channel quality within specification over long-haul and metro links. As a passive, span-specific module, it is typically matched to a particular fibre route’s measured dispersion during network design or re-engineering. Tech-Star (UK-based, shipped worldwide) supplies the 1AB210830002 for DWDM network builds and spares. Contact our team to confirm exact specification and stock.
