Zorluk: OrtaPhysical Interface and Cabling Types

Network physical interfaces use specific transceiver standards designed for different cabling media, connector types, and maximum distances. Match each Ethernet transceiver standard to its corresponding physical medium and operational distance specification.

  • 10GBASE-LRSingle-Mode Fiber (SMF) using LC connectors up to 10 km at 1310 nm
  • 1000BASE-SXMultimode Fiber (MMF) using LC connectors up to 550 m over OM3
  • 100GBASE-SR4Multimode Fiber (MMF) using MPO/MTP multi-fiber connectors up to 100 m
  • 10GBASE-TCategory 6A (Cat6a) balanced twisted-pair copper cabling up to 100 m

Cevap

10GBASE-LR matches Single-Mode Fiber (SMF) using LC connectors up to 10 km at 1310 nm; 1000BASE-SX matches Multimode Fiber (MMF) using LC connectors up to 550 m over OM3; 100GBASE-SR4 matches Multimode Fiber (MMF) using MPO/MTP multi-fiber connectors up to 100 m; 10GBASE-T matches Category 6A (Cat6a) balanced twisted-pair copper cabling up to 100 m.
Each Ethernet optical and copper transceiver designation specifies its exact physical media type, wavelength, connector, and maximum supported distance according to IEEE 802.3 standards.

Adım Adım Çözüm

1
Identify the optical fiber classification and range for 10GBASE-LR
The 'LR' stands for Long Range, which utilizes 1310 nm lasers over single-mode fiber (SMF) up to 10 km.
Single-mode fiber is required for long-range high-bandwidth transmission due to minimal modal dispersion.
2
Identify the optical fiber classification and range for 1000BASE-SX
The 'SX' suffix denotes short-wavelength 850 nm optics designed for multimode fiber (MMF) reaching up to 550 m over OM3 grade fiber.
Multimode fiber utilizes LED or VCSEL light sources for shorter intra-building runs.
3
Identify the multi-lane 100G fiber specification for 100GBASE-SR4
The 'SR4' suffix indicates short-range 4-lane optics requiring parallel MPO/MTP multi-fiber push-on connectors up to 100 m.
Parallel optics aggregate four 25 Gbps lanes across separate fiber strands inside a ribbon cable.
4
Identify the copper Ethernet standard for 10GBASE-T
The 'T' suffix indicates twisted-pair copper media using standard RJ-45 connectors, specifically requiring Cat6a for full 100-meter 10 Gbps runs.
Category 6A cabling mitigates alien crosstalk required for 10 Gbps operation up to 100 meters.
