EXECUTIVE SUMMARY

The Nokia G-140W-MD is a GPON Optical Network Terminal (ONT) designed for Home Gateway Unit (HGU) applications in FTTH deployments. This datasheet provides authoritative engineering specifications for optical sensitivity thresholds, power consumption profiles, and electrical requirements. The device integrates PON, voice, gateway, and LAN switching functions into a single System-on-Chip (SOC) architecture, delivering carrier-grade performance with optimized energy efficiency. Operators deploying the G-140W-MD gain a proven platform for delivering high-speed Internet, VoIP, and IPTV services over a single fiber infrastructure.

HARDWARE ARCHITECTURE & SILICON

The G-140W-MD is built around a highly integrated MTK chipset that consolidates GPON MAC, voice processing, Layer 3 routing, and Ethernet switching into a unified silicon platform. This architectural approach eliminates discrete component interconnects, reducing both bill-of-materials complexity and power overhead. The optical subassembly supports GPON Class C+ performance, ensuring compatibility with extended-reach ODN deployments.

KEY FEATURES

- GPON Compliance: Full ITU-T G.984.x protocol support with Class C+ optical module

- Optical Interface: SC/APC connector with low insertion loss (<0.5 dB)

- Power Efficiency: 25% power reduction through integrated SOC design

- Forwarding Performance: GE line-rate bridging and 900 Mbit/s NAT throughput

- Management: TR-069 remote provisioning, OMCI per G.988, and local web UI

- Service Ports: 1×GE, 3×FE, 1×POTS, 1×USB, and 2.4GHz WiFi

OPTICAL SENSITIVITY CHARACTERISTICS

The G-140W-MD operates on standard GPON wavelengths: 1490 nm downstream and 1310 nm upstream. The optical receiver is specified for Class C+ sensitivity, supporting fiber reach up to 20 km. Deployment guidance indicates that fiber light levels below -27 dBm trigger registration failures, with contaminated SC/APC endfaces identified as the predominant root cause in field diagnostics . The optical link budget accommodates typical ODN loss scenarios including split ratios up to 1:64 and connector losses.

POWER REQUIREMENTS & CONSUMPTION PROFILE

The device is powered via an external AC-DC adapter with universal input acceptance. The power architecture employs a single-stage conversion topology with system-level power management. Static power consumption is documented at 5W, while maximum power draw under full load reaches 15.5W . Typical operating consumption is rated at 8W, reflecting real-world mixed-service conditions .
