Product Description

Industrial Gigabit Ethernet Switch Overview

Switch principle
This entry was reviewed by the "Encyclopedia of Science Popularization" scientific encyclopedia entry preparation and application project.

NT-IN322BF Industrial Ethernet Switch series is an industrial-standard 4-port Gigabit Switch with dual fiber port redundancy, providing 2-port 10/100/1000BASE-TX Ethernet ports and additional two 100/ 1000Base-FX fiber ports.

A switch is a network device used to forward electrical (optical) signals. It can provide a unique electrical signal path for any two network nodes of the access switch. The most common switch is an Ethernet Switch.

Rigorous industrial design makes it stable and reliable with basic protection, as well as flexible enough for Ethernet expansion in harsh industrial environments.

The switch works at the second layer of the OSI reference model, the data link layer. The switch has a high-bandwidth back bus and internal switching matrix, which can perform data transmission between multiple port pairs at the same time.

When the main fiber broke down, NT-IN322BF Gigabit unmanaged industrial siwtch can switch to redundant fiber within 1ms.

The transmission mode of the switch is full-duplex, half-duplex, and full-duplex / half-duplex adaptive. [1]

NT-IN322BF Industrial Switch series is either rack-mountable with DIN rail or panel mounted in cabinet for easy installation.

Chinese name Switch principle Foreign name Switch principle Wiring standard Twisted pair connection, twisted pair is 8 core

Wide range of working temperature, power supply backup, IP40 protection, LED indicators and compact design, all these make NT-IN322BF a perfect solution for special industrial application site.

NT-IN322BF-AT (AF) Industrial Gigabit Ethernet Switch series is the POE version of NT-IN322BF with two POE Ethernet ports, powering POE IP camera, AP and IP phone over Ethernet cable. NT-IN322BF-AT (AF) Industrial Gigabit Ethernet switch supports IEEE802.3at with 25.5W output, compatible with IEEE802.3af.
