Mini Fiber Optic Media Converter PCBA – 2x RJ45 to 3x SFP, Single Mode, Fast Ethernet

Core Specifications and Network Capability

The BYXGD Mini Fiber Optic Media Converter PCBA is a small, but powerful signal converter that allows you to convert optical signals back into electrical signals using Ethernet. The board measures 80mm x 70mm and has been developed for the development of integrated communications systems and industrial applications where space and stability are vital to the end product.

This particular converter has 2 RJ45 Ethernet ports and 3 SFP fiber ports, all of which support 10/100 Mbps full-duplex transmission in non-blocking wire-speed. The SFP ports in this model work with both 155M and 1.25G modules, providing flexibility and compatibility when connecting to fast fiber networks. Because of its high compatibility, it is ideal for mixed environments moving away from legacy fast Ethernet towards newer gigabit systems.

The converter has been designed with single-mode, single-fiber fiber transmission. A standard module can transmit distances as far as 3 kilometers; with a long-range SFP option, the maximum distance is 120 kilometers. This makes it the ideal solution for point-to-point fiber applications using wavelengths 1310nm / 1550nm.

Power Management and Stability

Instead of using an internal power brick, the PCBA employs an internal power management circuit that can receive inputs of 5V to 24V DC. By doing so, the board is protected from voltage fluctuations that occur in industrial control, transportation, and mining applications.

A highlight of the PCBA is that it is capable of Power Daisy-Chaining several converter boards from a single power source, providing less complicated wiring and reducing the amount of power wasted in systems. Therefore, a single regulated DC output from the PCBA can supply power to multiple units, making the integration of the modular racks or enclosures easier.

The PCBA was designed with reliability in mind, so passive cooling was also adopted. The chassis design does not contain any mechanical components (such as bearings in fans) and therefore operates silently, which extends the life of the PCBA even when it is subjected to high levels of dust or vibrational forces. Because the module’s typical power consumption is very low (usually less than 3 watts), passive cooling provides thermal stability without the use of airflow.

Embedded Design and Application Flexibility

The BYXGD Mini Fiber Media Converter PCBA provides a professional platform on which manufacturers, developers, and consumers can base their networking products. Its compact size allows for installation directly into a variety of applications, including small enclosures, base stations, and mining controls, while its layout also facilitates mechanical integration without compromising performance.

The non-PoE model eliminates power-related circuitry that would otherwise consume space and increase the complexity of the overall design. This makes the BYXGD Mini Fiber Media Converter PCBA the ideal choice for systems with existing DC power buses or for those systems where power regulation is managed elsewhere in the overall system.

Some typical applications of this product include:

• Industrial Automation & Safety Monitoring Networks
• Fiber Backhaul Networks used in Mining and Energy Production Sites
• Embedded Networking Products (such as Routers, Switches, and Hubs) installed in Compact or Sealed Enclosures
• FTTX (Fiber To The X) or Point-to-Point Fiber Links requiring High Reliability and Low Heat Generation.

Manufacturing Quality and Certifications

The BYXGD fiber media converter products are fully manufactured in China (Guangdong) with strict adherence to quality assurance procedures. The Mini PCBA uses the latest technology and adheres to all applicable FCC, CE, and RoHS standards for electrical safety and environmental health. Every unit is fully functional and thermally tested before being shipped.

The company offers a three-year warranty, which is indicative of the manufacturer’s confidence in the product’s ability to withstand long-term operation in even the most challenging environments.

OEM and Customization Capability

In addition to the usual 5 ports found on most equipment, BYXGD offers full support for deep OEM/ODM customization on their hardware architecture, including options for modifying the hardware to include more optical or RJ45 ports as per engineer requests.

• Typical configuration: 3x SFP + 2x RJ45 (with Fast Ethernet)
• Options available to customize: Scalable platform that can be configured from a minimum of two ports (combined optical and copper) through to a maximum of up to 48 ports; configurable input voltages; unique mechanical dimensions that can be tailored to clients’ specifications.

This scalability allows for many converters to be placed within a high-density enclosure or custom controller, all while providing the same level of electrical and optical performance.

Specifications
