Zorluk: ZorNetwork and Peripheral Cables and Connectors

A network infrastructure technician is cataloging cables and connectors required for an upcoming enterprise data center deployment. Which of the following correctly matches each cable or connector type to its primary deployment requirement or specification?

  • Single-Mode Fiber with LC ConnectorTransmits light over long distances (up to 40 km) using a narrow laser beam and a small form factor push-pull latching connector.
  • Cat 6a Shielded Twisted Pair (STP)Delivers 10 Gbps Ethernet throughput over distances up to 100 meters while mitigating electromagnetic interference (EMI).
  • USB 3.2 Gen 2x2 Type-C CableSupports dual-lane operation to achieve up to 20 Gbps data transfer rates for high-speed peripheral connections.
  • RS-232 Serial Cable with DB-9 ConnectorEnables legacy out-of-band management interfaces to directly configure router and switch command-line consoles.

Cevap

Each cable type matches its corresponding technical capability: Single-Mode Fiber with LC matches long-distance laser transmission with push-pull latching; Cat 6a STP matches 10 Gbps up to 100m with EMI shielding; USB 3.2 Gen 2x2 Type-C matches dual-lane 20 Gbps peripheral transfer; RS-232 DB-9 matches legacy out-of-band switch console management.
Single-Mode Fiber (LC) provides long-distance optical networking up to tens of kilometers; Cat 6a STP delivers 10 Gbps copper networking up to 100 meters with noise protection; USB 3.2 Gen 2x2 Type-C uses dual-lane transmission to achieve 20 Gbps; and RS-232 DB-9 provides direct out-of-band console access for network hardware configuration.

Adım Adım Çözüm

1
Identify the long-distance optical connection requirement.
Single-mode optical fiber utilizes a small-core glass fiber for laser transmission across tens of kilometers, standardizing on LC push-pull connectors for high-density switches.
Single-mode fiber is designed specifically for long-haul optical links beyond the distance capabilities of multi-mode fiber or copper cabling.
2
Evaluate the 10 Gbps copper twisted-pair requirement.
Cat 6a cabling maintains 10 Gbps speeds up to 100 meters, and its STP variants offer shielding against industrial EMI.
Standard Cat 6 is limited to 37-55 meters for 10 Gbps, whereas Cat 6a guarantees 10 Gbps up to 100 meters.
3
Determine the peripheral storage interconnect specification.
USB 3.2 Gen 2x2 leverages dual-lane operation exclusively available on Type-C cables to deliver 20 Gbps.
Single-lane USB 3.2 Gen 2 delivers 10 Gbps; doubling the active lanes inside Type-C cabling doubles throughput to 20 Gbps.
4
Identify the out-of-band management interface requirement.
RS-232 DB-9 serial cables connect computer serial ports to local console ports of network switches and routers.
Serial connections provide low-level out-of-band administration regardless of network IP protocol status.
