4/2/2024 0 Comments Ethernet testing proceduresThe number of LAN users is increasing so quickly that backbones are once again ready for a tenfold boost in throughput, and as a result, last March, the IEEE officially approved the development of a 10-Gigabit Ethernet standard for backbone communications. The two-year-old Gigabit Ethernet standard from the Institute of Electrical and Electronics Engineers (IEEE-New York City) for local-area-network (LAN) backbone signaling no longer sufficiently satisfies the exploding demand for bandwidth. Shaded boxes represent fiber-optic physical layers, and clear boxes represent twisted-pair layers. This chart shows the hierarchy of Ethernet physical-layer standards, including the 10-Gbit/sec specification under development. These newest developments in high-speed Ethernet transmission over fiber-optic media have forced the industry as a whole to take a closer look at field-testing issues associated with emerging standards. Today, fiber-optic installations are quickly growing in number and bandwidth to alleviate the throughput bottlenecks on backbone networks where traffic from multiple workstations aggregates. With more test-limit sets on the horizon, a field-tester's versatility becomes paramount.
