Features & Benefits

• Single-mode fiber support extends the network over long distances (20 km).
• Auto MDI/MDIX and auto speed/duplex provide ease of installation.
• Link Fault Pass-Through keeps your copper and fiber connections strong.
• Compact, chassis-free design fits easily in any setup.
• Low power consumption (~2.4 W) keeps energy use low.
• Easy-to-read LEDs provide instant status at a glance.

Ideal Use Cases

• Extend Ethernet devices to distant buildings or towers over extended fiber runs.
• Add access points, IP cameras, or switches to fiber backbone.
• Mount independently or rack-mounted in pairs, with TP-Link chassis.
• Bridge fiber spans where copper cable max (100 m) does not reach.

Technical Insight

This media converter translates 100 Base-FX (fiber) to 100 Base-TX (copper Ethernet) through a 1310 nm longwave laser. It performs full wire-speed forwarding with flow control in both directions. The Link Fault Pass-Through feature notifies faults on one side to the other immediately, enabling network recovery quickly. Thanks to auto-negotiation and Auto MDI/MDIX, no manual network configuration is required.
