10/100M Fast Ethernet Media Converter with Fiber Support up to 120km
Overview
The LNK-1100 Series Fast Ethernet Media Converter converts 10/100Base-TX copper signals to 100Base-FX optical fiber, supporting multi-mode and single-mode fiber transmission. It extends network distances from 100m via copper to up to 120 km via fiber, making it ideal for industrial, campus, and long-distance network applications. With auto-sensing duplex, MDI/MDI-X, QoS, and flexible transmission modes, it ensures reliable and high-performance connectivity.
Features
Flexible media conversion – 10/100Base-TX to 100Base-FX fiber
Long-distance transmission – up to 120 km over single-mode fiber
Auto-sensing & duplex support – full/half duplex, MDI/MDI-X auto detection
Transmission modes – store-and-forward or 100Mbps cut-through
Enhanced network performance – QoS support for VoIP and VLAN traffic
Compact & efficient – low power consumption (<2W), MTBF 100,000 hours
LED indicators – power, fiber link/activity, TP link/activity, duplex, rate
Flexible fiber options – multi-mode dual fiber, single-mode dual or single fiber
