Understanding the FTTH Power Continuity 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 stay powered to maintain service continuity. According to Shanghai Mylion New Energy Co., Ltd., a global B2B provider operating under the brand MYLION, short power outages, voltage drops, or unstable grid conditions frequently cause this equipment to reboot or lose service entirely. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, these interruptions translate directly into service-level failures at the subscriber's premises.
Mylion also points to a secondary, often overlooked risk: improper UPS selection. When voltage, current, peak load, or connector specifications are mismatched to the actual device, the resulting backup power application can fail even when a UPS unit is installed. This insight shapes Mylion's entire approach to FTTH backup power.
Mylion's Engineering-Led Approach to Backup Power
Mylion positions itself as a B2B backup power partner and OEM/ODM project partner, rather than a generic power accessory supplier. The company's differentiated approach centers on evaluating solutions based on real device voltage, working current, peak or startup behavior, and installation environment. Before a project moves forward, Mylion provides technical confirmation and connector/cable matching to reduce selection errors—directly addressing the mismatch problem described above.
This methodology is backed by more than 13 years of experience in lithium battery technology and more than 10 years of experience in Mini UPS development. The company's stated value proposition is to support more reliable DC backup deployment while reducing avoidable selection risks for professional project customers, which is precisely the concern facing FTTH operators managing large, distributed equipment fleets.
Product Lineup Built for FTTH Equipment
Mylion's product matrix spans ten Mini UPS and DC backup models, organized into series that map directly to common FTTH scenarios.
Standard 12V Series for Everyday ONTs and Routers
The 12V Standard Series is positioned for entry-level to mainstream broadband backup. The MU26W offers a 12V DC input supporting up to 3.5A, a 12V DC output of 2.5A continuous (3A maximum), and 18.72Wh of battery capacity, using DC5521 input and DC5525 output interfaces—suited to short outages that would otherwise cause router or ONT reboots. The MU48W raises capacity to 29.6Wh with the same 2.5A continuous/3A maximum output, using a center-positive DC5525 output, targeting ISP and broadband network equipment. The MU68W extends this further with 44.4Wh of energy and a maximum output of 36W (12V/3A), intended for professional ISP projects requiring longer runtime.
Long-Runtime Series for Extended Outages
For residential or remote-area deployments facing long-duration power outages, the 12V Long-Runtime Series—represented by the MU635W and MU635L—delivers 75.6Wh of battery energy while maintaining the same 2.5A continuous/3A maximum 12V DC output as the standard series, prioritizing prolonged service continuity for standard CPE devices.
High-Power Series for Demanding Gateways
Some FTTH gateways and high-performance routers exceed the standard 2.5A threshold. The MU65W in the 12V High-Power Series addresses this with a 12V DC input supporting up to 6A and an output of 4A continuous/5A maximum (60W total), backed by 56.16Wh of battery energy—built for high-performance WiFi equipment and storage-integrated gateways. The 12V High-Power Long-Runtime Series, covering the MU35W and MU35L, combines that same 60W output capability with 75.6Wh of battery capacity, serving professional gateways that require both high peak current and extended backup time.
Multi-Output and AC-Input Series for Combined Installations
Many FTTH installations involve more than a single powered device. The 12V + USB Multi-Output Series addresses this directly: the MUJ46 provides a 12V DC output of 1.5A continuous/2A maximum alongside dual 5V/3A USB-A and USB-C outputs, within an 18W system limit and 37.44Wh battery energy—allowing simultaneous backup for a router and a USB accessory. The MUJ435 extends runtime with 50.4Wh of energy while retaining the same 12V DC plus 5V USB-A/USB-C port configuration and 18W system limit.
For installations combining an ONT and a router from a single AC wall outlet, the AC-Input Dual Output Series offers the ML1202AC: an AC-input dual 12V LiFePO4 UPS accepting 100–240V AC and delivering two independent 12V DC outputs (2A each, 24W total system limit) from 25.6Wh of battery energy, eliminating the need for a separate external DC adapter for each device.
Mylion also lists two directions currently under project evaluation rather than general sale: the MUC85, a USB-C PD Mini UPS targeting modern WiFi 6/7 devices with 65W standard/100W maximum PD input and 92.16Wh battery energy, and the MU248, a 24V/48V telecom backup direction built on LiFePO4 chemistry with independent 24V (3A) and 48V (1A) outputs, a 100W system limit, and 102.4Wh of battery energy for higher-voltage wireless CPE and radio bridge equipment.
Certification, Compliance, and Project Support
Mylion's lithium battery products are developed with adherence to lithium battery transport documentation and model-specific compliance requirements, including UN38.3 and MSDS certifications on a model-specific basis. On the service side, Mylion supports B2B project work, OEM/ODM services, and sample validation, covering requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination. This extends through managed pilot evaluation and mass-production preparation, giving FTTH-focused customers a structured path from technical assessment to deployment.
Why FTTH Operators Choose Mylion
For telecom operators, ISPs, broadband network companies, fiber network operators, and system integrators evaluating backup power for FTTH service continuity, Mylion's value lies in matching real electrical requirements—voltage, current, and connector type—to a defined product range rather than offering a one-size-fits-all accessory. Platform compatibility spans routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification for each deployment. Pricing follows a custom enterprise and project-based quote model, and deployment is designed around device-side hardware installation for subscriber-side equipment, supported by technical evaluation, model matching, and project-specific documentation coordination.
