Match each Ethernet physical interface transceiver standard to its corresponding physical cabling medium, optical wavelength, and maximum distance specification.
- 10GBASE-SROperates at an 850 nm wavelength over OM3 Multimode Fiber (MMF) supporting 10 Gbps throughput up to 300 meters.
- 1000BASE-LXOperates at a 1310 nm wavelength over Single-Mode Fiber (SMF) supporting 1 Gbps throughput up to 5 kilometers.
- 1000BASE-TOperates using four wire pairs of Category 5e or higher Unshielded Twisted Pair (UTP) copper up to 100 meters.
- 10GBASE-LROperates at a 1310 nm wavelength over Single-Mode Fiber (SMF) supporting 10 Gbps throughput up to 10 kilometers.
Cevap
10GBASE-SR matches 850 nm OM3 MMF up to 300 m; 1000BASE-LX matches 1310 nm SMF up to 5 km; 1000BASE-T matches 4-pair Cat 5e/6 UTP up to 100 m; 10GBASE-LR matches 1310 nm SMF up to 10 km.
Each physical interface type is uniquely defined by its transmission speed (1G vs 10G), medium (Copper UTP, MMF, or SMF), optical wavelength (850 nm vs 1310 nm), and distance limit (100 m, 300 m, 5 km, 10 km). Matching these characteristics correctly ensures physical layer compatibility and prevents signal degradation over specified link lengths.
