The industrial-grade fiber optic media converter DS201 can operate in either low latency converter mode or store & forward switching mode. The fiber interface supports 100Mbps/1000Mbps SFP by dip switch configuration. It detects and changes to switch mode if the copper and fiber speed or duplex are different. In converter mode, the Link Fault Pass-Through (Link Loss Forwarding) reaches low latency with bi-directional alert and auto-recovery. The 16Kbytes jumbo frame forwarding capability guarantees high-speed Giga communications. Wide operation temperature -40~75C and heavy industrial EMC design brings DS201 suitable for any industrial application.
