The statement that a network using the 1000Base-T standard operates at one gigabit per second is accurate. The 1000Base-T Ethernet standard is specifically designed for transmission of data at a rate of 1 Gbps (gigabit per second) over twisted-pair copper cabling, typically using Category 5e (Cat 5e) or Category 6 (Cat 6) cables. This standard enables high-speed networking over relatively short distances—up to 100 meters—making it suitable for many local area network (LAN) configurations.

In contrast, networks using fiber optic cables, like those specified in other standards (for example, 1000Base-LX or 1000Base-SX), do not apply in this case. 1000Base-T does not utilize coaxial cables, as it is intended for twisted-pair connections. Moreover, 1000Base-T employs standard RJ-45 connectors for its connections, which are readily available and do not require special or proprietary connectors. Thus, the operational characteristics defined in the B choice are specifically relevant to the 1000Base-T standard, establishing its applicability in modern networking environments.
