Tips: Half-duplex and full-duplex
Half-duplex means that the sending and receiving of the same media is asynchronous. In contrast, full duplex has separate transmit and receive paths. Full-duplex links are the key to extending Fast Ethernet (100Mbps). A full-duplex link network segment cannot exceed two devices, and can be a network card or switch port.
10BASE-T and 10BASE-FL have separate transmit and receive paths, and full duplex can be performed depending on the complexity of the network card or switch port. If these interfaces are configured in half-duplex mode, the synchronous detection of receiving and transmitting will trigger the collision detection. The same interface is set to full duplex, and collision detection is disabled because full duplex does not follow the shared CSMA/CD rules.
As mentioned above, the network range at 100 Mbps has been reduced due to collisions. For twisted pair segments and switch ports, the longest distance of the segment is 100 meters (within the collision domain). The problem is that on fiber ports, for multimode fiber, the length of the network segment is 2 kilometers. For single mode fiber, it is 15 kilometers. In the half-duplex mode, it is limited by the collision domain, and the network segment distance is 412 meters. Therefore, only in full-duplex mode (CSMA/CA is ignored), the extension of the fiber segment can reach its limit.
