Transition SISTF1011-111-LR ST 100BFX Twisted Pair Media Converter

Product Description

This Fast Ethernet media converter facilitates the interconnection of 100 Mbps Ethernet networks operating over twisted-pair copper cabling with those using multimode fiber optic cabling. The SISTF1011-111-LR converts the electrical signals from the 100BASE-TX copper interface to optical signals for transmission over 100BASE-FX multimode fiber, and vice versa. This conversion is essential for extending network reach beyond the 100-meter limit of copper Ethernet and for providing immunity to electromagnetic interference (EMI). The converter features a standard RJ-45 port for copper connections, typically supporting auto-negotiation for speed (10/100 Mbps) and duplex modes. The fiber optic port uses an ST connector, a common and reliable interface for multimode fiber, allowing for communication up to 2 kilometers. This makes it suitable for applications within buildings, across campuses, or in industrial environments where longer cable runs or electrical noise are concerns. Operating in store-and-forward mode, the converter ensures data integrity by checking for errors before forwarding packets. It is powered by an external power adapter and includes comprehensive LED indicators for power, link status, and data activity on both the copper and fiber ports, aiding in network monitoring and troubleshooting. The 'LR' designation in the SKU might imply 'Long Reach' within the context of multimode fiber, though the standard 2km distance is typical for 100BASE-FX.
