10/100M Single Fiber Converter 120km 48VDC Power Input Industrial Grade

Product Overview
The LNK-S1100D Series Single Fiber Media Converter provides cost-effective 10/100M Ethernet conversion between twisted pair (RJ45) and single-mode fiber (100Base-FX) networks. Featuring intelligent link failure detection, this converter eliminates the need for expensive managed switches while extending network reach from 100m over copper to 120km over fiber. Its dual-mode operation (L1 cut-through/L2 store-and-forward) ensures optimal performance for diverse industrial and telecom applications.
