RS is a superset of RS and expands on the capabilities. For your easy reference, a quick comparison chart listed below demonstrates the key differences of these three commonly used serial interfaces for industrial applications. In terms of serial-to-fiber media converters, there are two kinds of connection mode: pair and ring. The working principles of them are different. Pair Connection Mode The Pair Connection simply extends the point-to-point transmission distance of the serial connection.
Two serial-to-fiber converters can be connected over a fiber cable between a computer and a serial device. These two locations can be up to 12 miles 20 km apart. The working principle of serial to fiber converter will differ as per the input, output, and transmission requirements of the network. The following are two popular topologies, which are widely adopted by industrial networks across the globe.
Gaining an understanding of these topologies will help you understand the workings of these devices as well. A converter may be connected to two other media converters, and the signal conversion from electrical to optical or vice versa takes place between these alternating converters.
Ring topology is usually employed for long-distance transmissions. It supports up to km transmission. High dependability is touted as one of the main drawbacks of this topology.
If one converter fails to perform, it may affect the performance of the entire loop. Ring topology is also suited for managed serial media converters. When connected in a ring mode, the features of managed switches are put best to use and they assure optimized performance and better data conversion. This assures quick point-to-point data conversion. Although effective, this topology is best suited for short distances such as 20 km networks and so on. Quality control is deeply integrated in our manufacturing and stringently followed through all phases of manufacturing.
