Alcatel-Lucent KFA632 10G Optical Interface Carrier

The Alcatel‑Lucent KFA632 (also designated WMOTBUKLAA) is a high‑performance 10 Gbps optical interface carrier module designed for use in carrier‑grade transport and routing systems. This module provides a flexible, pluggable interface for 10G Ethernet, SONET/SDH, and OTN (Optical Transport Network) applications, enabling seamless integration into metro, long‑haul, and data center interconnect networks.

Overview

The KFA632 optical interface carrier is typically deployed in Alcatel‑Lucent chassis platforms such as the 7750 SR series routers or optical transport nodes. It accepts standard SFP+ or XFP optical transceivers, allowing operators to choose the appropriate reach and wavelength for their specific link requirements. The module supports a wide range of protocols, including 10GBASE‑R, OC‑192/STM‑64, and OTU‑2, making it a versatile solution for mixed‑traffic environments. Its hot‑swappable design simplifies maintenance and upgrades without service disruption.

Key Features

• 10 Gbps line rate with support for Ethernet, SONET/SDH, and OTN framing

• Pluggable SFP+ or XFP optics for flexible reach (up to 80 km or more with DWDM)

• Support for digital diagnostics monitoring (DDM) for real‑time optical performance

• Forward error correction (FEC) for improved link budget and error resilience

• Hot‑swappable field‑replaceable unit (FRU) for easy maintenance

• Compliant with ITU‑T G.709, IEEE 802.3ae, and Telcordia GR‑253 standards

• Management via SNMP, TL1, and CLI for performance monitoring and fault detection

• Optical Interfaces: 1x SFP+ or XFP slot (customer‑selectable)

• Wavelength Support: 1310 nm, 1550 nm, or DWDM (ITU grid) depending on SFP+

• Reach: Up to 10 km (SR), 40 km (LR), 80 km (ER), or >100 km (DWDM with amplification)

• Connector Type: LC duplex (on SFP+/XFP)

• FEC: Integrated G.709 FEC (OTN) and RS‑FEC (Ethernet)

• Power Consumption: 8 W typical (without SFP+)

• Operating Temperature: 0°C to 45°C (ambient chassis temperature)

• Dimensions: Standard carrier card form factor (e.g., 1U or half‑slot)

Applications

This optical interface carrier is ideal for:

• Metro Ethernet aggregation and core routing

• Long‑haul DWDM transport with optical amplification

• Data center interconnect (DCI) over dark fiber

• Mobile backhaul for LTE/5G aggregation

• Enterprise WAN extension and leased line services

Integration and Management

The KFA632 module integrates seamlessly with Alcatel‑Lucent network management systems, such as the 5620 SAM and 1350 NM. Operators can monitor optical power, temperature, and bias current via DDM, and receive alarms for signal loss, degradation, or hardware faults. The module supports in‑service software upgrades and can be remotely configured for different protocol modes.

Installation and Maintenance

Installation involves inserting the carrier module into the appropriate chassis slot, installing the SFP+/XFP transceiver, and connecting the fiber optic cable. The system automatically detects the module and negotiates the link parameters. Routine maintenance includes cleaning optical connectors, verifying DDM readings, and replacing the SFP+/XFP if faults are detected. The hot‑swap capability allows replacement without powering down the chassis.

Conclusion

The Alcatel‑Lucent KFA632 WMOTBUKLAA 10G optical interface carrier offers a flexible, high‑performance solution for 10G optical transport in demanding network environments. Its protocol‑agnostic design, pluggable optics, and robust management features make it a reliable choice for carriers and enterprises seeking scalable, future‑proof connectivity.
