After the distribution network plan is developed, the next step we have to do is the selection of the right fiber optic cable. Remember the bulk of the Fiber Optic Cable installed today is for either telephone or office applications. Industrial sites bring some challenges that are not address by many of the common fiber optic cable installation design. Just due to the local telephone company would rather a particular type of fiber optic cable does not mean it is the right one for a facility.
Driven by the rising demand for higher bandwidth and faster speed connections for a variety of industrial and residential purposes, fiber optic transmission is becoming more and more common in modern society. In this tutorial, the advantages and disadvantages of fiber optic transmission will be explored in details.
Fiber optic cable, which is lighter, smaller and more flexible than copper, can transmit signals with faster speed over longer distance. However, many factors can influence the performance of fiber optic transmission. Losses in optical fiber are negligible issues among them, and it has been a top priority for every engineer to work with and figure out solutions for.
There are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics. The article will compare these four kinds of fibers from history,the side of core size, bandwidth, data rate, distance, color and optical source in details.
A loopback cable is also known as loopback plug or loopback adapter, which is a plug used to test physical ports to identify network issue. It provides system test engineers a simple but effective way of testing the transmission capability and receiver sensitivity of network equipment.
