Fibre Multiplexing: An Overview of Time Division Multiplexing (TDM)

Fibre multiplexing is a technique used to transmit multiple signals over a single fibre optic cable, allowing for efficient use of bandwidth and high transmission rates. There are several different methods of fibre multiplexing, including time division multiplexing (TDM).

In this article, we’ll take a closer look at TDM and its key features and benefits.

What is Time Division Multiplexing (TDM)?

Time division multiplexing (TDM) is a method of transmitting multiple signals over a single fibre optic cable by assigning each signal to a specific time slot. This allows for efficient use of bandwidth, as the cable is used effectively and there is less risk of congestion.

However, TDM also has some limitations. One major limitation is that the transmission rate of each signal is limited by the time slot assigned to it. This means that if a signal requires a larger time slot, it may not be able to be transmitted at the same rate as other signals.

Overall, TDM is a useful method of fibre multiplexing that can provide efficient use of bandwidth and high transmission rates in certain situations. It’s important to carefully consider your specific needs and requirements when deciding which method of fibre multiplexing is right for you.
