Unmanaged Hardened Gigabit Ethernet Media Converter

Unmanaged Hardened Gigabit Ethernet Media Converter
(1) 10/100/1000Base-T Port + (1) 1000Base-SX/LX Port or (1) 100/1000Base-X Port

SISTG10xx-211-LRT-B Series



The SISTG10xx-211-LRT-B Series is a new generation of unmanaged hardened Gigabit Ethernet media converter. The converter can provide multimode or single mode fiber connections with fixed SC connectors for extending the Ethernet service distance over fiber. The converter also has a SFP version that provides the ultimate flexibility to choose the appropriate SFP module to match your communication and distance needs.

It has redundant input power connections to ensure safe reliable operation in temperatures between -40°C and +75°C. Transition Networks’ hardened switches are certified with UL Class 1 Division 2 to operate reliably in hazardous locations such as Oil & Gas, manufacturing, and the chemical industry.
