ALCATEL 3AL79176AAAD01 1660SM, 1670SM Telecom System Card / Module

The ALCATEL 3AL79176AAAD01 is a P4S4N four-port STM-4 optical interface card for the Alcatel-Lucent 1660SM and 1670SM synchronous digital hierarchy platforms. It provides four independent STM-4 (622 Mbit/s) optical ports on a single card, each accepting the appropriate physical optical module for the required connector type (FC/PC, SC/PC or LC) and wavelength/reach combination such as S-4.1 or L-4.1/L-4.2, letting operators consolidate several STM-4 tributary or aggregate connections into one card slot. The P4S4N is used where shelf density matters and a single-port STM-4 card would use slots inefficiently, and it shares its family relationship with the single-port S-4/L-4 optical cards used elsewhere on the same platforms. Tech-Star (UK-based, shipped worldwide) supplies tested ALCATEL 3AL79176AAAD01 cards for engineers maintaining Alcatel-Lucent SDH transport. Get in touch to confirm stock and compatibility.
