The 2xRJ45 to 4xSFP 10/100/1000Base‑T Single Mode SC PoE Media Converter is great conversion technology available today, enabling seamless transitions between copper and fiber optics in the FTTH model. This helps customers bridge the gap between their home networks and the optical networks that serve them while offering cost-efficiency and improved performance.
Design and Construction
It features a durable and rugged design, measuring 190 × 95 × 30 mm. It is constructed with an aluminum alloy that provides a high level of thermal conductivity, helping to dissipate excess heat. Inclement weather, extreme temperatures, and electromagnetic interference (EMI) can cause equipment failures.
Performance and Transmission
The 2xRJ45 to 4xSFP converter is designed specifically for high-speed, rapid response applications and supports both single-mode and multi-mode fiber. Single-mode fibers provide transmission distances of 3 km, 20 km, 40 km, 60 km, 80 km, and 120 km, while multi-mode fibers support distances up to 550 meters.
Operating wavelengths are 1310 nm and 1550 nm, reducing fiber attenuation and ensuring excellent long-distance performance across multiple ports. The internal backplane design has a bandwidth of 12 Gbps and an 8.94 Mpps packet forwarding rate.
The built-in advanced chip technology for low latency and low power consumption provides the highest resistance to electromagnetic interference, making it an optimal solution for applications such as high-definition video monitoring, VoIP, and other applications with strict latency requirements.
Optical Interface Flexibility
The unit is equipped with 4 1000Base‑X SFP slots, providing maximum flexibility for different optical connections. Instead of being limited to a fixed connector, users can choose LC, SC, FC, or ST interfaces simply by selecting the corresponding SFP modules. It supports both single-mode and multi-mode fiber, with transmission distances ranging from 550 m to 120 km depending on the selected module. The unit can be configured as either Single-mode Dual-fiber or BiDi (Single-fiber/WDM), depending on the equipment requirements of your project. This flexibility makes it ideal for retrofitting complex networks and operating in a wide range of telecommunications environments while allowing easy future expansion with minimal maintenance.
Power and PoE Capability
The media converter supports PoE+ according to the IEEE 802.3af/at standards and transmits PoE power through the RJ45 ports. PoE devices connected to the unit are automatically detected, and the unit provides up to 30 W per port as needed; non-PoE devices remain protected from damage.
A power-priority algorithm is implemented to ensure that critical devices do not lose power when the load is high, minimizing downtime. Power is supplied to the unit using a 3C‑certified 48–57 V DC power adapter (standard 52 V), providing over‑voltage, over‑current, and short‑circuit protection for connected devices.
The media converter itself consumes less than 6 W under normal operation. With its certified power module and overload protection circuitry, the unit continues to work safely and reliably even under voltage fluctuation.
Intelligent Functionality
The device’s robustness is matched by its intelligence. It is built with a high‑precision domestic chipset designed for both high‑speed packet processing and stable signaling capabilities. Its adaptive MDI/MDIX allows it to automatically detect which port it will connect to and eliminates the need for manual configuration of cables.
The device has a plug‑and‑play feature that does not require additional configuration or management interfaces, which greatly simplifies the installation process and increases deployment efficiency in large-scale projects such as IP video systems and building networks.
Other features include:
- Minimal Latency – Supports low latency for real‑time video streaming.
- Low Power Consumption – Designed for energy efficiency.
- Excellent Anti‑Aging Properties – Delivers consistent long‑term performance.
- Noise Immunity – Maintains data integrity in noisy environments.
Reliability and Certification
A global variety of converters is subjected to an extensive evaluation process before being submitted for certification. All certified converters have received CE, FCC, and 3C approval, ensuring compliance with electromagnetic compatibility and electrical safety standards.
The power module is manufactured with a flame‑retardant enclosure and advanced circuit protection, all of which contribute to an extended life for the hardware. With a 3‑year warranty, customers can rely on long‑term performance and technical support.
Customization Options
The device can be customized according to the specific requirements of the project:
- Connector Types: Determined by SFP module (LC, SC, FC, ST optional)
- Distance Options: Single‑Mode – 20 km, 40 km, 60 km, 80 km, 100 km, 120 km; Multi‑Mode – 550 m
- Power Adapters: EU, UK, US, BR, AU standards available
- Fiber Configuration Modes: Single‑Mode Dual‑Fiber, Single‑Mode Single‑Fiber (BiDi), Multi‑Mode Dual‑Fiber
Typical Application Scenarios
The PoE Media Converter has a wide range of applications in modern networks:
- FTTH, FTTB, FTTX Optical Broadband Systems
- Campus, Residential Community, and Hotel Network Projects
- Security Surveillance and IP Camera Systems
- Large‑Scale LAN / Enterprise Backbones
- Broadcasting and Teleconferencing Networks
- Internet Cafes / Industrial Network Expansions
Because of its stability for transferring data, as well as its range, it is typically used in both Backbone Links and Last Mile Access Solutions.
