A fiber optic modem (FOM) acts as a connecting interface between an electronic device and an internet network. These modems are different than regular DSL modems because the signal transmission is not via copper cables. It uses a fiber optic cable network to transmit signals. It transforms electronic communication signals via a fiber-optic network. Fiber optic modems (FOM) are nowadays being used in several applications such as data communication network systems, inter-network communication systems, etc. Since these fiber optic modems are gaining popularity, it is important to have information about before using it blindly. This post gives you insights about these fiber optic modems and their working.
The working of a fiber optic modem is quite simple. The following pointers will help you understand it better.
There are different categories of fiber optic modems according to the data transmission protocol followed by the modem. Let us discuss the types of FOM in brief.
That Make Them Popular FOMs are gaining popularity over DSL modems and cable transmission due to their beneficial features. The fiber optic modems offer the following benefits.
