Understanding the Fiber Internet Backup Power Challenge
Fiber internet service depends on a chain of powered devices sitting at the customer premises — ONTs, ONUs, routers, modems, gateways, and CPE units. Any of these devices can reboot or drop service during a short power outage, a voltage drop, or an unstable grid condition. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, this creates a recurring reliability gap that standard AC power protection does not always solve. Shanghai Mylion New Energy Co., Ltd., operating globally under the brand MYLION, has built its entire business around closing this specific gap with Mini UPS products and DC backup power solutions designed for telecom, ISP, broadband, and security applications.
Why Generic Power Backup Often Falls Short
A core industry pain point identified by MYLION is that improper UPS selection — regarding voltage, current, peak load, or connectors — can lead to application failure even when a backup device is technically installed. Network equipment has specific voltage requirements, working current demands, and peak or startup current behavior that must be matched precisely. Selecting a backup unit without evaluating these real device characteristics and the installation environment is a common source of avoidable deployment risk. This is the exact problem MYLION positions itself to solve as a B2B backup power partner and OEM/ODM project partner, rather than a general consumer electronics supplier.
MYLION's Approach to Fiber Internet Backup Power
Differentiated Advantages: MYLION evaluates solutions based on real device voltage, working current, peak/startup behavior, and installation environment, combined with technical confirmation and connector/cable matching to reduce selection errors. The company's value proposition centers on supporting more reliable DC backup deployment and reducing avoidable selection risks for professional project customers — a positioning built on more than 13 years of experience in lithium battery technology and more than 10 years of experience in Mini UPS development.
Technical Capabilities
MYLION's proprietary R&D is focused specifically on Mini DC UPS technical content and ISP/broadband backup power applications. Its technical portfolio covers 12V DC systems up to 60W, LiFePO4 chemistry integration, and emerging USB-C PD 100W input / 65W output capabilities. Platform compatibility extends to routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification for each use case.
Product Matrix Built for Fiber and Broadband Backup
MYLION offers ten products and development directions organized into distinct series, each addressing a different fiber internet backup power scenario.
12V Standard Series — The MU26W is an entry-level 12V Mini UPS supporting 2.5A continuous / 3A maximum output, 18.72Wh battery capacity, and a DC5521 input / DC5525 output interface, suited to telecom, ISP, and home networking equipment. The MU48W offers mid-range 29.6Wh capacity with the same 2.5A continuous / 3A maximum output through a center-positive DC5525 output, aimed at ISP and broadband network equipment. The MU68W steps up to 44.4Wh energy with a maximum 36W (12V/3A) output, positioned for professional ISP projects.
12V Long-Runtime Series — The MU635W / MU635L models deliver 75.6Wh of battery energy while maintaining 2.5A continuous / 3A maximum output, designed for long-duration power outages in residential or remote areas where standard CPE devices need prolonged service continuity.
12V High-Power Series — The MU65W targets high-load CPE or gateways that exceed standard 2.5A thresholds. It supports up to 6A DC input and delivers 4A continuous / 5A maximum output (60W total) with 56.16Wh battery energy, suited to high-performance WiFi equipment and storage-integrated gateways.
12V High-Power Long-Runtime Series — The MU35W / MU35L combine 4A continuous / 5A maximum output with 75.6Wh battery energy, supporting 60W output for professional gateways that require both high peak current and long backup time.
12V + USB Multi-Output Series — The MUJ46 provides simultaneous 12V DC output (1.5A continuous / 2A maximum) plus dual 5V/3A USB-A and USB-C ports within an 18W system limit and 37.44Wh battery energy, fitting small office / home office setups that need to power a router and a USB accessory at once. The MUJ435 extends this concept with 50.4Wh battery energy across the same 12V DC + 5V USB-A + 5V USB-C port configuration and 18W system limit.
AC-Input Dual Output Series — The ML1202AC is an AC-input dual 12V LiFePO4 UPS accepting 100–240V AC and delivering two 12V DC ports (2A each; 24W total system limit) with 25.6Wh battery energy, simplifying installations where an ONT and a router need backup from a single AC wall outlet without an external DC adapter.
Development / Project-Evaluation Directions — The MUC85, currently under development, is a USB-C PD Mini UPS accepting 65W standard / 100W max input, with one USB-C output up to 20V/3.25A (65W) and a second up to 12V/2.5A (30W), backed by 92.16Wh battery energy for modern WiFi 6/7 devices requiring USB-C Power Delivery. The MU248, also under development, addresses 24V / 48V telecom backup needs using LiFePO4 chemistry, accepting 48V / 60V DC input and providing independent 24V (3A) and 48V (1A) outputs within a 100W total system limit and 102.4Wh battery energy, aimed at higher-voltage wireless CPE and radio bridge equipment.
Service Model Supporting ISP and Fiber Network Deployments
MYLION's service capabilities extend beyond hardware. The company provides B2B project support, OEM/ODM services, and sample validation, covering requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination. This supports managed pilot evaluation and mass-production preparation for telecom operators, ISPs, system integrators, distributors, and brand owners. On the compliance side, MYLION adheres to lithium battery transport documentation and model-specific requirements, including UN38.3 and MSDS certifications where applicable to specific models.
Pricing follows a custom enterprise and project-based quote structure, reflecting the company's focus on B2B and OEM/ODM relationships rather than standardized retail sales. Deployment is handled through device-side hardware installation for subscriber-side equipment, with after-sales support including technical evaluation, model matching, and project-specific documentation coordination.
Conclusion
Fiber internet backup power is not a one-size-fits-all problem. The diversity of ONT, router, modem, gateway, and CPE power requirements means that selection mistakes around voltage, current, peak load, or connectors can undermine even a well-intentioned backup deployment. Shanghai Mylion New Energy Co., Ltd., through its MYLION brand, addresses this directly with a structured product matrix spanning standard, long-runtime, high-power, multi-output, AC-input, and emerging USB-C PD and 24V/48V directions — all supported by technical evaluation services built specifically for telecom, ISP, broadband, fiber networking, and security customers worldwide.
