Mini UPS for FTTH Networks: MYLION’s Backup Power Guide

Why FTTH Deployments Need Reliable Backup Power

Fiber-to-the-Home (FTTH) networks depend on continuous power at the customer premises to keep ONTs, ONUs, routers, modems, and gateways online. Short outages, voltage drops, or unstable grid conditions frequently cause these devices to reboot or lose service entirely. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, this translates into dropped connections, support tickets, and dissatisfied subscribers. A mini UPS designed specifically for FTTH equipment addresses this gap by maintaining power during brief interruptions, preserving service continuity at the point where it matters most: the subscriber’s premises.

Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, is a global B2B provider of Mini UPS products, DC backup power solutions, and project support built around this exact pain point. Headquartered in Shanghai, China, with business coverage extending globally, MYLION positions itself as a backup power partner and OEM/ODM project partner for telecom, ISP, broadband, and security applications.

The Core Selection Problem in DC Backup Power

A recurring issue in FTTH and broadband deployments is improper UPS selection. Mismatches in voltage, current, peak load, or connector type can cause application failure even when a backup unit is technically present. MYLION addresses this through evaluation of solutions based on real device voltage, working current, peak and startup behavior, and the installation environment. The company provides technical confirmation and connector or cable matching to reduce selection errors before deployment, rather than after equipment has already failed in the field.

This approach reflects MYLION’s broader value proposition: supporting more reliable DC backup deployment and reducing avoidable selection risks for professional project customers. With over 13 years of experience in lithium battery technology and more than 10 years focused specifically on Mini UPS development, MYLION brings accumulated technical depth to a category that is often treated as an afterthought in network equipment planning.

A Product Portfolio Built Around FTTH Use Cases

MYLION’s catalog spans ten distinct products organized into series that map directly to the realities of FTTH and broadband backup scenarios.

The 12V Standard Series covers entry-level to mainstream broadband backup. The MU26W supports 2.5A continuous current with 12V DC output and 18.72Wh of battery capacity, suited for standard routers and ONTs during short outages. The MU48W offers mid-range capacity at 29.6Wh with a center-positive DC5525 output for ISP and broadband network equipment, while the MU68W extends runtime further with 44.4Wh of energy and a maximum output of 36W for professional ISP projects.

For deployments requiring extended backup duration, the 12V Long-Runtime Series, including the MU635W and MU635L, provides 75.6Wh of battery energy while maintaining the same 2.5A continuous / 3A maximum 12V output, specifically positioned for long-duration power outages in residential or remote areas.

Where equipment draws more current than standard thresholds, the 12V High-Power Series MU65W delivers 4A continuous and 5A maximum output (60W total), supporting high-performance WiFi equipment and storage-integrated gateways that exceed the common 2.5A ceiling. Combining this higher output with maximum runtime, the 12V High-Power Long-Runtime Series (MU35W/MU35L) pairs 60W output capability with 75.6Wh of battery capacity, intended for professional gateways that require both high peak current and long backup time.

For installations that must support more than one device type, the 12V + USB Multi-Output Series offers the MUJ46 and MUJ435, each combining 12V DC output with dual 5V USB-A and USB-C ports under an 18W total system limit—practical for small office and home office setups where a router and a USB accessory need simultaneous backup. The AC-Input Dual Output Series ML1202AC takes a different approach, drawing directly from a 100–240V AC wall outlet and distributing power to two separate 12V DC ports (2A each, 24W total) using LiFePO4 battery chemistry, simplifying deployment for combined ONT and router installations without requiring an external DC adapter.

Looking ahead, MYLION’s Development and Project-Evaluation Directions include the MUC85, a USB-C PD Mini UPS under development aimed at modern WiFi 6/7 devices requiring USB-C Power Delivery (65W standard, 100W max input), and the MU248, a 24V/48V telecom backup direction using LiFePO4 chemistry for higher-voltage wireless CPE and radio bridge equipment with independent 24V and 48V outputs under a 100W system limit.

Technical Foundations Supporting FTTH Reliability

MYLION’s product portfolio spans 12V DC systems up to 60W, LiFePO4 chemistry integration, and emerging USB-C PD 100W input/65W output capabilities. This range allows project teams to match backup power precisely to device requirements rather than relying on oversized or undersized generic solutions. Platform compatibility extends to routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification—underscoring MYLION’s emphasis on confirming real-world compatibility rather than assuming it.

On the compliance side, MYLION adheres to lithium battery transport documentation and model-specific compliance requirements, including UN38.3 and MSDS certifications where applicable to specific models. This attention to documentation matters for ISPs and system integrators managing cross-border shipments of battery-based equipment.

Service Model: From Requirement Analysis to Mass Production

MYLION’s service capabilities are structured around B2B project support, OEM/ODM services, and sample validation. The service scope includes requirement analysis, model matching, sample testing support, connector and cable matching, private labeling, and documentation coordination. For project customers, this means a path that begins with technical evaluation and sample testing and extends through managed pilot evaluation to mass-production preparation.

This end-to-end structure is particularly relevant for FTTH-focused customers—telecom operators, ISPs, system integrators, distributors, and brand owners—who need backup power solutions validated against their specific device fleets before committing to large-scale rollout. Pricing follows a custom enterprise and project-based quote model, reflecting the variability in device requirements, volume, and OEM/ODM customization across different FTTH deployment contexts.

Conclusion

For organizations deploying or maintaining FTTH network equipment at the subscriber premises, power interruption remains a persistent operational risk. MYLION’s Mini UPS lineup, backed by over a decade of lithium battery and Mini UPS development experience, offers a structured range of 12V, long-runtime, high-power, multi-output, AC-input, and emerging USB-C PD and telecom-voltage solutions. Combined with a service model built on technical evaluation, connector matching, and documentation support, MYLION presents itself as a backup power partner suited to the technical and logistical demands of global FTTH, broadband, and security equipment deployments.
