ALCATEL 3AL78856BE 1640FOX, 1660SM Telecom System Card / Module Image 1

L-4.2N single-port STM-4 extended long-haul optical interface card (FC/PC) for the Alcatel-Lucent 1640FOX and 1660SM.

The ALCATEL 3AL78856BE is an L-4.2N single-port STM-4 extended long-haul optical interface card for the Alcatel-Lucent 1640FOX and 1660SM SDH platforms, fitted with an FC/PC connector. It provides a single STM-4 (622 Mbit/s) optical port with a higher-power L-4.2 optic than the L-4.1N variant, giving operators additional link budget for the longest unrepeated SDH spans on 1640FOX and 1660SM shelves. The card occupies the same slot format as the rest of the single-port STM-4 optical card family (S-4.1N, L-4.1N) and is selected in place of those variants specifically where span loss requires the extra optical power. Tech-Star (UK-based, shipped worldwide) supplies tested ALCATEL 3AL78856BE cards for engineers keeping Alcatel-Lucent SDH rings running. Contact us to confirm stock and compatibility.
