  • 1000BASE-LX Transceiver (operating over MMF)Multimode Fiber using 1310 nm wavelength requiring a mode-conditioning patch cord for 550 meters reach
  • 10GBASE-LR SFP+ TransceiverSingle-Mode Fiber using 1310 nm wavelength with a 10-kilometer reach
  • 100BASE-TX InterfaceCategory 5e/6 UTP Copper cable using RJ-45 connectors with a 100-meter limit

Cevap

10GBASE-SR SFP+ matches Multimode Fiber using 850 nm wavelength up to 300 m on OM3; 1000BASE-LX over MMF matches Multimode Fiber using 1310 nm wavelength requiring a mode-conditioning patch cord for 550 m reach; 10GBASE-LR SFP+ matches Single-Mode Fiber using 1310 nm wavelength up to 10 km; 100BASE-TX matches Category 5e/6 UTP Copper cable up to 100 m.
Each physical transceiver and interface type has specific operating wavelengths, core media requirements, and distance bounds: 10GBASE-SR uses 850 nm lasers on multimode fiber up to 300 meters (OM3); 1000BASE-LX can run over multimode fiber at 1310 nm up to 550 meters when using a mode-conditioning patch cord; 10GBASE-LR operates over 1310 nm single-mode fiber up to 10 kilometers; and 100BASE-TX uses twisted-pair copper with RJ-45 connectors up to 100 meters.

Adım Adım Çözüm

1
Identify copper media standards among the options
Classify 100BASE-TX as unshielded twisted-pair (UTP) copper media operating up to 100 meters with RJ-45 terminations.
The suffix -TX in IEEE 802.3 standards denotes twisted-pair copper specifications.
2
Differentiate 10 Gigabit optical transceiver specifications
Pair 10GBASE-SR with 850 nm multimode fiber (300m reach on OM3) and 10GBASE-LR with 1310 nm single-mode fiber (10 km reach).
Short Range (-SR) optics rely on lower-cost 850 nm VCSEL lasers for multimode cores, whereas Long Range (-LR) optics require 1310 nm Fabry-Perot/DFB lasers for single-mode fiber.
3
Analyze legacy Gigabit Ethernet deployment nuances over MMF
Associate 1000BASE-LX operating on legacy MMF with the mode-conditioning patch cord requirement to reach 550 meters.
Coupling a single-mode laser directly into the center of a multimode fiber core causes multiple light modes to propagate asynchronously (differential mode delay), which is corrected by offset laser launch via a mode-conditioning patch cord.
