PoE Switches

PoE switches are products that enable communication between the devices in a network by using Power-over-Ethernet (PoE) technology. These switches feature a built-in PoE junction for power management and data transmission simultaneously over a twisted-pair cable. Owing to the PoE functionality, these PoE/PoE+ switches can power the devices in the network during  active data transmission. These switches act as the plug-and-play modules between the main power source and multiple devices in the network.
 
VERSITRON provides a range of multi-port managed PoE switches featuring 4 to 52 ports for copper-to-fiber conversion. Our PoE and PoE+ switches also offer built-in SFP ports for fiber optic connectivity compatible and RJ45 copper ports.

PoE Switches Explained in Detail

The PoE switches are the devices that enable targeted data transmission and power transmission over a single twisted-pair cable. The power over Ethernet switches with SFP modules can be used for dual transmission over a fiber optic cable as well. The PoE switches eliminate the need for an additional power source between the main power sourcing equipment (PSE) and the powered devices (PDs) as the integrated devices in the Ethernet network are powered by the PoE powered source.
 
PoE switches working

The PoE enables the data transmission between a data source to the receiver equipment. However, the power function of these switches relies on the following components of the PoE system.
  • Power Sourcing Equipment (PSE):

    The power transmission in a PoE system takes place between a power source and a powered device (PD). The source of power that transmits power to the Ethernet cable is referred to as power sourcing equipment (PSE).
    PSE can be connected to powered devices (PD) in one of the following two ways.
    • ENDSPAN:

      ENDSPAN is the PoE transmission where there is absolutely no need for an additional power supply from PSE to PD.
    • MIDSPAN:

      MIDSPAN is the PoE transmission where an additional power supply is integrated at the mid-length of the transmission cable. Commonly, PoE injectors are used as MIDSPAN power supply in the PoE systems.
  • Powered Device (PD):

    The device that consumes the power transmitted by Ethernet cable is known as a powered device (PD). There can be one or multiple powered devices (PDs) in the PoE system. The powered devices can be VoIP phones, IP cameras, etc.
  • Ethernet Cable:

    Ethernet cable is the intermediate bidirectional transmission media between the PSE and PDs. The Ethernet cable can be a twisted-pair copper cable or fiber optic cable. It enables the transmission of data and power simultaneously.

What Devices Can be powered by PoE Switches?

PoE Ethernet switches can power the devices at 15.4W, however, network switches with PoE+ specifications can power the devices at 25.5W. VERSITRON’s Gigabit PoE switches and PoE+ switches can be used to power the following PDs in an Ethernet network.

Features and Specifications of PoE/PoE+ Switches Analyzed

PoE power switches are gaining in popularity over other types of devices because they rarely require an additional power supply. Their ability to transmit data and power devices over a single cable makes them popular over other types of switches. These switches use only one cable to supply the data and power.
 
VERSITRON’s Gigabit PoE Ethernet switches offer the following features and specifications.
  • Versatile Transmission Rate:

    The rate of transmission varies according to the media of transmission adopted in the PoE network switches. PoE switches and PoE+ switches offer transmission at a data rate of 10/100/1000mbps over a distance of 100 meters.
    • Ethernet: 

      Our industrial switches offer a 10 Mbps transmission rate.
    • Fast Ethernet:

      Our Fast Ethernet switches can transmit a data rate of 100Mbps. 
    • Gigabit Ethernet:

      The Gigabit Ethernet switches assure a 1000 Mbps data transmission rate.
  • Cable Compatibility:

    Our standard PoE Ethernet switches are compatible with Cat5e and Cat6 twisted-pair cables. SFP integrated PoE and PoE+ switches are compatible with multimode and singlemode fiber optic cable.
  • Compliance with Industrial Standards:

    PoE/PoE+ switches are compatible with the following standards.
    • IEEE 802.3- 10BASE-T Ethernet
    • IEEE 802.3 Auto-Negotiation
