Review Questons 1. The original commercial version of Ethernet supported 10 Mbps bandwidth; the version introduced in the early 1990s supports 100 Mbps; and in 1998, Gigabit Ethernet was introduced. All versions use the same data frame formats, with the same maximum PDU sizes, so they can interoperate freely.
1000BASE-SX/LX. The IEEE 802.3-2002 is a gigabit Ethernet solution over fiber that supports half-and full-duplex transmission at speeds of 1Gbps (1000mbps). The 1000Base-SX standard was developed to support lower cost multimode fiber runs in horizontal and shorter-length backbone applications.he IEEE 802.3-2002 is a gigabit Ethernet solution over fiber that supports half-and full-duplex transmission at speeds of 1Gbps (1000mbps).
