Product Features
Technical Overview
This media converter handles Fast Ethernet (10/100Base-T) over twisted pair and 100Base-X over fiber, ensuring seamless integration into existing network infrastructures. The four RJ45 ports support standard Ethernet cables, while the two SC ports connect to single-mode fiber optic cables, minimizing signal loss over long distances.
The device supports both optical fiber and twisted pair media, with a maximum reach of 20 km on fiber. Its 1300 nm wavelength is optimized for single-mode fiber applications, providing stable performance in extended network runs. Power is supplied via an external power adapter, and the low 9 W consumption contributes to energy-efficient operation.

Deployment / Use Cases
This media converter is ideal for scenarios requiring network extension over fiber, such as connecting remote offices, industrial control systems, or surveillance networks. It effectively bridges copper-based LAN segments to fiber backbone links.
Common applications include extending Ethernet over single-mode fiber in campuses, manufacturing plants, or data centers. The converter also suits environments where electrical isolation or immunity to electromagnetic interference is needed, thanks to its fiber optic connectivity.
Industrial Network Integration
Deploy in manufacturing or utility settings to connect Ethernet devices over long distances, leveraging fiber's durability and noise resistance.
Building-to-Building Links
Use to link network segments between separate structures, utilizing the 20 km fiber reach to maintain high-speed connectivity without additional repeaters.
Physical Profile
The converter measures 3.60 inches in height, 3 inches in width, and 1.70 inches in depth, with a weight of approximately 12.80 ounces. Its small footprint and multiple mounting options facilitate installation in space-constrained areas like network cabinets, control panels, or wall enclosures.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 3.60" (91.44 mm), 3" (76.20 mm), 1.70" (43.18 mm), 12.80 oz (362.87 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
