Zorluk: ZorPhysical Interface and Cabling Types

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.

Adım Adım Çözüm

1
Identify the transmission speed and medium type for each standard.
Standards starting with '1000BASE' denote 1 Gbps, while '10GBASE' standards denote 10 Gbps. 'T' indicates twisted-pair copper, 'SR' indicates short-range multimode fiber, and 'LX'/'LR' denote long-reach single-mode fiber.
Ethernet standard nomenclature directly describes operational speed and physical media characteristics.
2
Map optical wavelength and maximum distance limits to each optic spec.
Short-range multimode optics (SR) utilize 850 nm VCSEL lasers (300 m reach on OM3). Long-range single-mode optics (LX/LR) utilize 1310 nm lasers (5 km for 1G LX, 10 km for 10G LR). Copper Gigabit (1000BASE-T) uses RJ-45 over Cat5e/6 for 100 m.
Wavelength and fiber core design (SMF vs MMF) dictate distance limitations due to modal dispersion and attenuation.
