Xelivor
Explore our core product lineup of premium 1.25G SFP transceivers, designed for absolute compatibility and optimized long-reach network stability.
In the rapid transition toward high-bandwidth architectures such as 100G, 400G, and 800G, the legacy and significance of 1.25G SFP (Small Form-factor Pluggable) modules remain absolute. Often referred to as the "workhorse of global telecom," the 1.25Gbps rate remains the primary architecture for vast swathes of edge routing, rural broadband networks, access layers, FTTH (Fiber-to-the-Home), and industrial control networks. The maturity of the 1000BASE standards ensures unparalleled transmission stability, extremely low power consumption, and highly cost-effective optical links over both multi-mode and single-mode fiber media.
Across the globe, industrial automation networks, transportation telemetry, municipal Smart Cities, and local government networks heavily depend on the SFP MSA (Multi-Source Agreement) form factor. By utilizing 1.25G modules, system integrators avoid high optical component upgrades, and instead extend the lifespan of installed enterprise switches and routers. This cost efficiency, combined with high-grade Digital Diagnostic Monitoring (DOM/DDM), permits network administrators to maintain live monitoring of laser telemetry, optical temperature, and Rx/Tx power, preventing network faults before they manifest.
Fully compatible with standard IEEE 802.3z standards and multi-vendor network platforms. Provides seamless drop-in upgrades without changing cabling infrastructure.
Extending networks up to 160km over single-mode fiber with optimized dispersion compensation and highly reliable 1550nm EML or DFB laser sources.
Operates at low power-consumption margins (<1W typical), ensuring lower thermal dissipation and extending the lifespan of core access switches.
Xelivor Optoelectronics Co., Ltd. is a pioneering manufacturer specializing in high-performance optical transceivers and integrated fiber connectivity solutions. Established in 2016, our production operations are housed within a modern 386 m² cleanroom facility. We operate under stringent quality management principles, delivering customized OEM/ODM services to distributors, system integrators, and telecom operators across North America, Europe, Southeast Asia, the Middle East, and South America.
Our competitive advantage lies in our manufacturing efficiency and advanced supply chain integration. By managing over 850 strategic raw material suppliers, we guarantee consistent component sourcing (including high-grade TOSA, ROSA, and BOSA optical sub-assemblies). This allows us to buffer inventory effectively, ensuring rapid order fulfillment and stable pricing even during global component shortages.
We deploy a specialized QA team of 32 expert inspectors. Each module undergoes incoming inspection, real-time wave monitoring, optical spectrum analysis, full-cycle thermal aging tests, and multi-platform compatibility validation.
Whether you require custom EEPROM code writing for proprietary switches, customized labels, bespoke housing layouts, or eco-friendly customized packaging, our R&D engineers adapt production to your design specifications.
Leveraging the world-class logistics infrastructure of our China-based export hub, we ship high-volume orders securely, reducing transit times to key global markets to a fraction of traditional lead times.
1.25G SFP transceivers serve critical functions across multiple localized settings. Here are the primary industries implementing these modules:
BiDirectional (BiDi) 1.25G SFP modules are widely deployed by telecom service providers. By utilizing wavelength-division multiplexing (WDM) via 1310nm/1550nm Tx/Rx paths over a single fiber, they effectively halve the cabling infrastructure costs for rural and suburban internet expansion projects.
In high-voltage power grids and factory floors, copper cabling is highly susceptible to electromagnetic interference (EMI). Industrial-grade 1.25G SFP transceivers, designed to withstand extreme operating temperature ranges (-40°C to 85°C), provide noise-free fiber backbones for industrial PLCs and remote terminal units.
Universities, hospitals, and corporate parks require fast, low-latency links across buildings. Utilizing 1000BASE-SX multimode modules over existing OM2/OM3 fiber backbones offers an extremely stable 550-meter gigabit connection at minimal cost.
When sourcing 1.25G SFP modules for large-scale enterprise deployments, procurement managers must evaluate parameters beyond basic pricing. Understanding technical nuances directly influences operational uptime and Total Cost of Ownership (TCO):
The global trend shows that despite higher speeds coming online, the demand for 1.25G SFPs is growing in IoT gateways and edge-computing nodes. Because modern smart-sensors and localized automation controllers do not generate terabytes of data, a stable, low-power 1G connection is optimal. As a result, maintaining a robust pipeline of high-quality 1.25G SFP modules remains vital for standard networking suppliers.
