Alcatel-Lucent 3AL92111AA 1P10GSO Interface Module

The Alcatel‑Lucent 3AL92111AA (also designated 1P10GSO) is a single‑port 10 Gbps optical interface module designed for use in high‑performance routing and switching platforms. This module provides a flexible, pluggable 10G Ethernet or SONET/SDH interface using standard SFP+ transceivers, making it a versatile choice for carrier backbone, metro aggregation, and data center interconnect applications.

Overview

The 3AL92111AA module is typically installed in Alcatel‑Lucent 7750 SR series routers or similar chassis. It occupies a single slot and offers one SFP+ port, supporting a variety of optical transceivers for short‑reach (SR), long‑reach (LR), and extended‑reach (ER) distances. The module operates at line rate and supports advanced features such as digital diagnostics monitoring (DDM), forward error correction (FEC), and comprehensive QoS marking. Its hot‑swappable design facilitates maintenance and upgrades.

Key Features

• Single 10 Gbps SFP+ port

• Supports 10GBASE‑SR, 10GBASE‑LR, 10GBASE‑ER, and DWDM SFP+ optics

• Line‑rate forwarding with low latency

• Digital diagnostics monitoring (DDM) for optical power, temperature, and bias

• Forward error correction (FEC) for enhanced link budget

• Hot‑swappable field‑replaceable unit

• Management via SNMP, CLI, and TL1

Technical Specifications

• Port: 1x SFP+ cage (accepts SFP+ and SFP modules)

• Data Rate: 10.3125 Gbps (Ethernet), 9.95 Gbps (SONET/SDH), 10.709 Gbps (OTU‑2)

• Supported Optics: SR (850 nm, up to 300 m), LR (1310 nm, up to 10 km), ER (1550 nm, up to 40 km), ZR (80 km), DWDM

• Connector Type: LC duplex (on SFP+)

• FEC: IEEE 802.3 Clause 74 RS‑FEC and G.709 OTN FEC

• Power Consumption: 5 W (without SFP+), additional 1‑2 W for SFP+

• Operating Temperature: 0°C to 45°C

• Dimensions: Standard half‑slot or full‑slot (varies by chassis)

Applications

This module is used for high‑speed uplinks in IP/MPLS core networks, metro Ethernet aggregation, and data center leaf‑spine architectures. Its single‑port design is ideal for connecting to other routers, switches, or optical transport systems over fiber.

Integration and Management

The module integrates with Alcatel‑Lucent network management systems, providing real‑time monitoring of optical parameters and link health. Administrators can configure speed, FEC, and alarm thresholds via the CLI or SNMP.

Installation and Maintenance

Install the module into the chassis slot, insert the SFP+ transceiver, and connect the fiber cable. The system automatically initializes the port. Routine maintenance includes cleaning optical connectors and checking DDM values for early warning signs.

Conclusion

The Alcatel‑Lucent 3AL92111AA 1P10GSO interface module offers a compact, high‑performance solution for 10G optical connectivity, ensuring reliable and scalable network expansion.
