Transition TR-CF-01(SM) Copper to Fiber RJ45 , ST Duplex Token Ring

Product Description

The Transition TR-CF-01(SM) is a specialized media converter designed specifically for legacy Token Ring networks. It facilitates the transition between copper-based Token Ring connections, typically using an RJ45 connector for UTP cabling, and fiber optic connections. The fiber side utilizes ST duplex connectors, which were a common standard for fiber optic networking, allowing for both transmit and receive signals. This converter enables network administrators to extend the reach of their Token Ring networks beyond the limitations of copper cabling. By converting the electrical signals to optical signals, the network can span greater distances, often up to 2 kilometers for multimode fiber, and gain immunity to electromagnetic interference (EMI). This is particularly valuable in industrial settings or large facilities where copper cabling might be susceptible to noise or where longer cable runs are necessary. The 'SM' in the part number likely indicates 'Single Mode' or 'Small Form Factor', but given the commonality of ST connectors with multimode fiber for such converters, it's more probable that it refers to the ST connector type or a specific chassis/form factor. This device is crucial for maintaining and extending existing Token Ring infrastructure where replacement with newer network technologies is not immediately feasible.
