10Base-F

10BaseF is the name given to a family of implementations of the physical layer of the telecommunications architecture (popularly known as Ethernet).

10BaseF uses fiber optics as the transmission medium for Ethernet networks at a speed of 10 Mbps.

The number 10 refers to the transmission speed, the word base refers to the transmission method (baseband), and the letter 'F& #39; refers to the transmission medium (optical fiber).

The 10BaseF Family

There are three implementations in this family:

• 10BASE-FL. An updated standard variant FOIRL.
• 10BaseFB. Directed to use in trollular networks. Today in disuse.
• 10BaseFP. Directed to topologies in passive-type star. It never developed.

Although outside of this family, there is another implementation adapted to the speed of 100 Mbps called 100BaseFX.

10BaseF in the context of Ethernet

The IEEE 802.3 standard architecture follows the OSI Reference Model for Telecommunications Architectures. Any architecture that follows this reference model must define its physical level. The physical layer describes the electrical (or optical) interfaces to perform the communication.

In the case of IEEE 802.3, several implementation alternatives have been defined for said physical layer. The best known are:

• 100BaseTX. Transmission on braided copper pair category 5. Very used.
• 10BaseT. Transmission on braided copper pair category 3. Still very used.
• 10Base2. Transmission on coaxial cable. Unused.

Evolution

The last type of cabling to date, and it is not the cabling for Fast-Ethernet systems, the 10Base-FX cabling type, which uses two multistage protocols, one in each direction of transmission between the center and the season. Like 10Base-T, the 10Base-FX system is a 10Mbit/s full-duplex network. However, the use of fiber optics as a communication medium allows the transmission of 10Mbit/s signals over distances of up to 2 km.
