Alcatel-Lucent 3AL00378AF Interface Card – Full Product Description
The Alcatel-Lucent 3AL00378AF is a high-performance line interface card designed for use in carrier-grade IP/MPLS and Ethernet aggregation platforms. This module provides multiple Gigabit Ethernet interfaces, advanced packet processing, and deep buffering capabilities to support demanding metro and core network applications. Its robust architecture and comprehensive feature set ensure reliable service delivery for both residential and business subscribers.
The 3AL00378AF is built around a state-of-the-art network processor that handles line-rate forwarding for all ports. The card supports standard Ethernet frame sizes up to 9,216 bytes (Jumbo Frames) and includes hardware acceleration for VLAN manipulation, QinQ stacking, and MPLS label imposition/disposition. Quality of Service is implemented through multiple hardware queues (up to eight per port), with support for strict priority, weighted round-robin, and deficit weighted round-robin scheduling algorithms.
Port configuration includes eight 10/100/1000BASE-T copper ports and four SFP-based fiber ports, offering flexibility for both short-haul and long-haul connections. The SFP ports support 1000BASE-SX, -LX, and -ZX optics, as well as 100BASE-FX, providing compatibility with a wide range of optical networks. The card also includes a dedicated management Ethernet port and a console port for out-of-band system access.
Traffic management features include hierarchical QoS with up to three levels of scheduling, shaping, and policing per port. The card supports dual-rate three-color marking (CIR/PIR) for ingress policing and egress shaping, enabling granular bandwidth control per subscriber or service. Congestion avoidance mechanisms such as Weighted Random Early Detection (WRED) help maintain optimal throughput during transient overloads.
The card incorporates advanced synchronization capabilities, including support for Sync-E (Synchronous Ethernet) and IEEE 1588v2 Precision Time Protocol (PTP) with hardware timestamping. This ensures accurate frequency and phase alignment for mobile backhaul and other latency-sensitive applications. The module also includes a programmable oscillator for holdover performance during loss of external reference.
Physical design emphasizes reliability and maintainability. The 3AL00378AF is a full-height, half-width card with a front panel that provides clear status LEDs for each port, power, and system health. The ejector/injector handles ensure secure insertion and extraction, and the board is keyed to prevent improper installation. A built-in temperature sensor monitors on-board heat dissipation, triggering alarms if thresholds are exceeded.
Management and monitoring are facilitated through the system's central management software, which provides comprehensive CLI and SNMP access. The card reports detailed statistics on per-port throughput, error counters, and QoS drops. It also supports remote loopback testing and RFC 2544 performance benchmarking for service turn-up and troubleshooting.
Environmental compliance includes operation in temperatures from 0°C to 50°C with humidity up to 85%. The card meets ETSI EN 300 386 and FCC Part 15 for EMC, and carries CE and UL certifications. Its MTBF is rated at 250,000 hours, backed by rigorous burn-in testing during manufacturing.
Typical deployment scenarios include Ethernet aggregation in mobile backhaul networks, enterprise VPN services, and as a subscriber-facing interface in broadband network gateways. The 3AL00378AF provides the density and performance required for efficient network scaling, while its advanced QoS and synchronization features enable differentiated service offerings.
Overall, the Alcatel-Lucent 3AL00378AF is a versatile, high-reliability interface card that delivers superior packet processing and connectivity. Its flexible port options, deep feature set, and manageability make it a valuable component for network operators seeking to optimize their IP/MPLS infrastructures for current and future traffic demands.
