How MYLION Prevents ONT Restarts During Power Interruptions

How MYLION Mini DC UPS Solutions Keep ONTs Online During Power Failures

For fiber broadband operators and Internet Service Providers, Optical Network Terminals (ONTs) serve as critical access points connecting subscribers to fiber networks. However, a persistent operational challenge threatens service continuity: power interruptions that cause ONT devices to restart, resulting in internet downtime, customer complaints, and increased field support costs. Shanghai Mylion Technology Co., Ltd. (MYLION) has developed specialized Mini DC UPS and telecom BBU solutions designed specifically to address this pain point for FTTH deployments and broadband network applications.

Understanding the ONT Power Interruption Challenge

ONTs installed at customer premises rely on continuous power supply to maintain network connectivity. Even brief power fluctuations, voltage drops, or adapter disconnections can trigger device reboots. These interruptions may last only seconds, but the resulting service disruption affects subscriber experience, generates remote troubleshooting workload, and often requires costly field technician visits.

The problem intensifies in regions with unstable electrical grids, where repeated power interruptions cause frequent ONT restarts throughout the day. Traditional solutions like bulky AC UPS systems prove impractical for residential installations due to size constraints, installation complexity, and cost considerations. MYLION recognized this gap and developed compact DC backup power solutions tailored specifically for ONT, router, modem, gateway, and CPE backup applications.

MYLION’s Specialized Approach to ONT Backup Power

Unlike generic UPS suppliers, MYLION positions itself as an engineering-driven B2B manufacturer focused on project-ready backup power systems for telecom and broadband infrastructure. With over 13 years of experience in lithium battery pack development and Mini DC UPS solutions, the company supports model selection based on actual device specifications rather than one-size-fits-all products.

The core value proposition centers on preventing ONT restarts through properly matched backup power. MYLION’s technical approach involves evaluating real working current, device voltage requirements, startup surge characteristics, connector compatibility, required backup time, and installation environment constraints before recommending specific models. This application-matching methodology helps ISPs and broadband operators avoid common pitfalls like insufficient runtime, connector mismatches, or inadequate current capacity that plague generic backup solutions.

Product Solutions for FTTH and ONT Applications

MYLION’s product portfolio includes several series specifically designed for fiber broadband and ONT backup scenarios:

Standard 12V Mini DC UPS Series (Models MU68, MU26, MU48) provides compact backup power for mainstream ONTs, routers, modems, and gateways. These models feature built-in lithium battery packs with BMS protection against overcharge, over-discharge, overcurrent, and short circuit conditions. The compact housing enables desktop, wall-mounted, or customer premises installation with optional connector, cable, label, and packaging customization for B2B projects.

Inline FTTH Mini UPS Series (Model MUJ46) addresses space-constrained installations common in fiber terminal deployments. This ultra-compact inline design connects between the original power adapter and the ONT device, providing DC-side backup without requiring additional installation space. The solution proves particularly valuable for FTTH deployments where clean installation and minimal visual impact matter to subscribers and installers alike.

High-Power 12V Telecom BBU Series (Models MU35, MU65) supports advanced ONTs and gateways with higher current requirements. Some modern fiber gateway devices demand more power than standard Mini UPS models can deliver. These high-current backup solutions accommodate demanding applications where peak load, startup surge, or sustained operating current exceeds typical low-power backup capacity.

Technical Differentiation: Beyond Simple Battery Backup

MYLION’s engineering focus distinguishes its solutions from consumer-grade power banks or generic UPS products. The company emphasizes several technical considerations critical for reliable ONT backup:

Real current measurement over adapter label ratings: Many installers mistakenly select backup power based solely on adapter specifications rather than actual device consumption. MYLION recommends measuring real working current and peak surge to ensure adequate safety margin.

Connector and cable matching: Different ONT models use varying DC barrel connector sizes and polarities. MYLION supports customized connector and cable configurations to ensure proper physical and electrical compatibility.

Backup time calculation: Required runtime depends on typical power interruption duration in specific deployment regions. MYLION helps customers calculate appropriate battery capacity based on measured device current and target backup duration.

BMS protection architecture: Built-in Battery Management Systems provide essential safeguards against abnormal operating conditions, enhancing safety for unattended residential installations.

Installation environment considerations: MYLION evaluates whether backup devices will experience temperature extremes, humidity exposure, or physical space constraints that affect product selection and housing design.

Supporting B2B Deployment Models

MYLION structures its business model around B2B telecom and ISP project requirements rather than retail consumer sales. The company supports multiple cooperation frameworks:

Standard product supply for distributors and system integrators building ONT backup inventory for regional markets.

OEM/ODM customization for telecom operators and broadband providers requiring private labeling, customized packaging, specific connectors, adjusted capacity, or project-specific documentation.

Sample testing programs allowing customers to validate backup performance with actual ONT devices before committing to volume orders.

Technical matching support including voltage/current evaluation, backup time estimation, connector confirmation, and certification coordination.

Project-based production with quality inspection protocols, export documentation, and international logistics support for mass deployment.

Quality and Compliance Framework

For telecom and ISP applications, product reliability and safety documentation prove as important as technical specifications. MYLION applies incoming material control, production process inspection, functional testing, and 100% outgoing inspection before shipment. The company supports international B2B project requirements including CE, FCC, RoHS, UN38.3, MSDS, and related certification documents depending on specific model configurations and project requirements.
