Alcatel-Lucent KFA18 OP155M/1.3IR16 Line Processing Unit

The Alcatel-Lucent 109091603006 KFA18 OP155M/1.3IR16 is a line processing unit designed for STM-1/OC-3 optical transport applications in synchronous digital hierarchy (SDH/SONET) network infrastructures. This module provides optical signal processing and regeneration functions for 155.52 Mbps client interfaces operating at 1310 nm wavelength over single-mode fiber. The KFA18 card integrates optical-to-electrical conversion, clock recovery, signal reshaping, and retiming (3R regeneration) capabilities to extend transmission reach and maintain signal integrity across metropolitan and regional network segments. It features standardized SC or LC optical connectors for fiber interface compatibility and supports automatic laser shutdown (ALS) for safety compliance. The unit connects to the shelf backplane via high-density edge connectors for power distribution at nominal −48 V DC and for communication with central system controllers. Performance monitoring functions include optical power level measurement, bit error rate (BER) calculation, and alarm indication signal (AIS) generation for fault isolation and service quality assurance. Management and configuration are handled through the platform's shelf controller using TL1, SNMP, or proprietary element management system interfaces. The module is engineered for hot-swappable installation in Alcatel-Lucent 1660/1640/1678 series transport platforms and complies with ITU-T G.707, G.783, and G.826 SDH standards. Environmental hardening includes operation across extended temperature ranges from −5 °C to +50 °C with humidity tolerance up to 95% non-condensing, meeting ETSI EN 300 019 and NEBS Level 3 specifications for telecommunications equipment deployment in central office and controlled data center environments.
