Zorluk: OrtaNetwork Hardware Devices

A network technician needs to connect a workstation in an outlying security office located 350 meters (1,148 feet) away from the main building's network switch. Fiber optic cabling has been installed between the two locations to overcome the 100-meter distance limitation of copper UTP cabling. However, neither the main switch nor the workstation possesses an SFP port or native fiber interface. Which of the following hardware devices should the technician deploy at both ends of the fiber run to bridge the connection?

  1. Media converterCevap
  2. B
    Layer 3 router
  3. C
    Power over Ethernet (PoE) injector
  4. D
    Unmanaged Layer 2 switch

Cevap

The correct device to deploy at both ends of the fiber run is a media converter.
A media converter is specifically designed to connect two dissimilar physical media types, such as copper Twisted-Pair (RJ-45) and fiber optic cabling. When existing network devices lack SFP transceiver slots, standalone media converters at each end of the fiber run translate electrical Ethernet signals into optical light pulses and back again.

Adım Adım Çözüm

1
Identify the physical layer cabling mismatch and distance requirements.
Copper Twisted-Pair (UTP) is limited to 100 meters, requiring fiber optic cabling for a 350-meter run.
Ethernet signals attenuate over copper cables beyond 100 meters.
2
Evaluate the endpoint hardware capabilities.
Neither endpoint possesses native fiber ports or SFP transceiver slots.
Direct fiber termination into the existing network equipment is impossible without signal translation.
3
Select the appropriate network hardware device for physical media translation.
A media converter receives copper RJ-45 Ethernet connections and translates electrical pulses into light signals for transmission over fiber, and vice versa on the remote end.
Media converters operate at Layer 1 to join disparate physical cabling media seamlessly.
