The unit operates with an external 5-VDC power adapter, featuring a barrel connector for reliable power delivery. Its compact, low-profile design allows flexible placement on flat surfaces or optional rack mounting using standard accessories, making it adaptable to various deployment scenarios without occupying significant space.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
This media converter eliminates distance limitations of copper cabalone by leveraging optical fiber, supporting runs up to 0.55 km while maintaining Gigabit throughput. Its dual media support provides network designers with a versatile tool for integrating fiber segments into existing copper-based networks without requiring wholesale infrastructure changes.
The inclusion of international power clips (US, EU, UK, AU) with the adapter ensures global deployment readiness, reducing the need for additional power accessories in multi-region installations.
Extended Reach
Overcomes the 100-meter limit of standard Ethernet copper by converting to fiber, enabling reliable connectivity across longer distances such as between buildings or across large facilities.
Backward Compatibility
Supports 10/100/1000Base-TX auto-negotiation, ensuring compatibility with existing Fast Ethernet and Gigabit Ethernet switches and devices without configuration hassles.
Deployment / Use Cases
Ideal for extending network segments beyond the reach of copper cabalone, this converter is commonly deployed in scenarios where fiber optic backbone connections meet copper-based edge networks. It serves as a cost-effective solution for integrating fiber into legacy infrastructure, avoiding expensive switch upgrades or complete rewiring.
Typical applications include connecting wiring closets to main distribution frames, linking separate buildings within a campus, or integrating fiber-based security cameras and access control systems into standard Ethernet networks. Its standalone or rack-mountable form factor suits both temporary setups and permanent installations in server rooms or network racks.
Campus Networking
Connect buildings across a campus using existing multi-mode fiber, extending Gigabit LANs between administrative offices, classrooms, and data centers without signal degradation.
Data Center Edge
Interface fiber backbone links with copper-based servers, storage, or networking equipment at the rack level, simplifying connectivity in mixed-media environments.
Physical Profile
The converter features a sturdy, compact chassis measuring 1" H x 3.70" W x 2.70" D (25.40 mm x 93.98 mm x 68.58 mm), with a lightweight design at 11.20 oz (317.51 g). Its low-profile footprint allows discreet placement on desks, shelves, or in crowded rack enclosures. The dual form factor supports both standalone use on any flat surface and optional rack mounting for organized installations in network cabinets or server racks.
