MYLION Mini UPS for FTTH Backup Power: A Technical Guide

Understanding the FTTH Power Interruption Challenge

Fiber-to-the-home (FTTH) networks depend on a chain of customer-premises equipment — ONTs, ONUs, routers, modems, gateways, and CPE devices — that must remain powered continuously to maintain service. Short power outages, voltage drops, or unstable grid conditions frequently cause these devices to reboot or lose connectivity entirely. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, even brief interruptions translate into service complaints, support calls, and degraded customer experience.

A recurring but often underestimated risk in deploying backup power is improper selection. Mismatches in voltage, working current, peak/startup load, or connector type can cause an otherwise functional UPS to fail in the field. This is precisely the gap that Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, is positioned to address as a global B2B provider of Mini UPS products, DC backup power solutions, and project support for telecom, ISP, broadband, and security applications.

What a Mini UPS Solution Needs to Deliver for FTTH

For FTTH backup power to function reliably, a solution must be evaluated against the real device it protects — not a generic power rating. MYLION's approach centers on assessing real device voltage, working current, peak/startup behavior, and installation environment, followed by technical confirmation and connector/cable matching to reduce selection errors. This evaluation-first methodology is intended to support more reliable DC backup deployment for professional project customers while reducing avoidable selection risks.

Core Technical Foundations

MYLION's technical capability is built on more than a decade of focused development: 13+ years of experience in lithium battery technology and 10+ years of experience in Mini UPS development. Its product portfolio spans 12V DC systems up to 60W, integrates LiFePO4 chemistry, and is extending into USB-C PD 100W input / 65W output capabilities for next-generation CPE.

MYLION's Product Portfolio for FTTH Backup Power

MYLION organizes its Mini UPS lineup into distinct series, each matched to specific FTTH and broadband scenarios.

12V Standard Series

The MU26W, MU48W, and MU68W form an entry-to-mainstream tier for standard broadband backup. The MU26W supports 12V DC input up to 3.5A and output of 2.5A continuous / 3A maximum, with 18.72Wh battery capacity and DC5521/DC5525 connectors — suited to home networking and standard router/ONT protection. The MU48W steps up to 29.6Wh with a center-positive DC5525 output for ISP and broadband equipment, while the MU68W extends capacity further to 44.4Wh with a maximum power output of 36W (12V/3A) for professional ISP projects.

12V Long-Runtime and High-Power Series

Where outages last longer, the MU635W/MU635L series provides 75.6Wh of battery energy at the same 2.5A continuous / 3A maximum 12V output, targeting residential or remote-area deployments with extended outage durations. For higher-load CPE and gateways exceeding standard 2.5A thresholds, the MU65W supports 12V input up to 6A and output of 4A continuous / 5A maximum (60W total) with 56.16Wh capacity — appropriate for high-performance WiFi equipment and storage-integrated gateways. The MU35W/MU35L combines this same high-power 4A/5A output profile with 75.6Wh capacity, serving professional gateways that require both high peak current and long backup time.

Multi-Output and AC-Input Options

For deployments powering more than one device, the MUJ46 and MUJ435 provide simultaneous 12V DC and USB-A/USB-C 5V outputs within an 18W system limit — practical for small office/home office (SOHO) setups running a router alongside a USB accessory. The ML1202AC addresses installations with two separate 12V devices from a single AC wall outlet: it accepts 100–240V AC input, uses LiFePO4 chemistry, and delivers two independent 12V DC ports (2A each, 24W total) — a configuration suited to combined ONT-plus-router installations.

Development Directions

MYLION is also advancing project-evaluation-stage products: the MUC85, a USB-C PD Mini UPS (65W standard / 100W max input) designed for WiFi 6/7 devices requiring Power Delivery, and the MU248, targeting 24V/48V telecom backup for higher-voltage wireless CPE and radio bridge equipment with a 100W total system limit.

Service Model: From Evaluation to Deployment

Rather than offering off-the-shelf units alone, MYLION structures its engagement around B2B project support, OEM/ODM services, and sample validation. This includes requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination — followed by managed pilot evaluation and mass-production preparation. Compliance elements such as UN38.3 and MSDS documentation are addressed on a model-specific basis, reflecting the regulatory requirements associated with lithium battery transport.

Industries and Customers Served

MYLION's business coverage is global, with its stated customer base spanning telecom operators, Internet Service Providers, broadband network companies, fiber network operators, system integrators, distributors, brand owners, and OEM/ODM customers across telecom, ISP, broadband, fiber networking, and security industries. Pricing follows a custom enterprise and project-based quote approach, and after-sales support includes technical evaluation, model matching, and project-specific documentation coordination — consistent with its positioning as a B2B backup power and OEM/ODM project partner rather than a pure retail supplier.

A Practical Path for FTTH Backup Power Planning

For organizations evaluating Mini UPS and DC backup power for FTTH and broadband customer-premises equipment, the underlying technical question is rarely about raw battery size alone — it is about matching voltage, current, peak load, and connector type to the actual device being protected. MYLION's model-by-model specifications, from the entry-level MU26W through the high-power MU35W/MU35L and into development-stage directions like the MUC85 and MU248, illustrate a structured approach to this matching process across standard, long-runtime, high-power, multi-output, and AC-input scenarios. Companies assessing backup power options for routers, ONTs, ONUs, modems, gateways, CPE devices, and security or CCTV equipment can use this breakdown as a reference point for aligning device requirements with available Mini UPS configurations, subject to electrical verification appropriate to each deployment.
