Key Features
Long-Distance Single-Mode Conversion
Converts 10/100Base-TX copper Ethernet signals to 100Base-FX single-mode fiber optic signals, extending transmission distances up to 25 km.
Dual SC Fiber Interface
Equipped with dedicated TX (transmit) and RX (receive) SC-type optical connectors for stable, full-duplex data transfer over standard single-mode fiber patch cables.
Auto-MDI/MDIX & Auto-Negotiation
The RJ45 Ethernet port automatically detects network speed (10 Mbps or 100 Mbps) and configures crossover or straight-through cable connections without requiring manual DIP switch adjustments.
Comprehensive Diagnostic LED Panel
Features front-facing LED indicators for Power (PWR), Link/Act, Full/Half Duplex (FDX), and Fiber Status (FX TX/RX), allowing quick, at-a-glance status monitoring and network troubleshooting.
Compact Heavy-Duty Metal Chassis
Enclosed in a rugged, heat-dissipating metal housing designed for standalone desktop use or installation into standard rackmount media converter chassis.
Plug-and-Play Simplicity
Requires no complex software configurations or driver installations—simply connect power, copper Ethernet, and single-mode fiber for immediate deployment.

Applications
- Long-Distance IP CCTV & Surveillance Extensions – Extends network connectivity for remote outdoor cameras, gate access control systems, and security booths situated beyond the 100 m copper Ethernet limitation (up to 25 km).
- Building-to-Building & Campus Networking – Connects separate office buildings, warehouses, or educational facilities over a dedicated single-mode fiber link without requiring expensive active network routing equipment.
- High-Noise Industrial Fiber Backbones – Replaces copper Ethernet links in electrically noisy industrial environments—such as near high-voltage lines, heavy generators, or manufacturing equipment—eliminating EMI/RFI signal corruption.
- Service Provider & ISP Last-Mile Delivery – Acts as an economical optical demarcation device for delivering 100 Mbps Fast Ethernet connections from ISP fiber lines into customer premises equipment (CPE).
- Enterprise Network Distance Expansion – Integrates distant workstation clusters, remote access points, or isolated network switches back to the primary core server rack.
