Lightem LF-8-1SFP
10/100M Ethernet Optical Fiber Switch with one SFP Fiber Interface
LF-8-1SFP is a 8port Fast Ethernet (10/100Mbps) Switch including one SFP (optical fiber module port) and
seven 10/100M UTP ports. With the SFP slot this switch can easily interface with Singlemode or Multimode fiber
with the right SFP module. Featuring stable performance, excellent quality and reasonable price.
Main features
Optical-Electric Ethernet signals between 10/100M UTP ports (TX) and
100M optical fiber interface (FX).
UTP port supports MDI / MDI-X auto crossover
SFP interface for easy choice of Singlemode or Multimode fiber interface
Broadcast storm protection
Supporting the max 1916 bytes frame
