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 Gigabit managed PoE+ switches featuring 4 to 52 ports with built-in SFP ports for fiber optic connectivity compatible and RJ45 copper ports.
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. These switches comply with the IEEE802.3af standard. They support a power consumption of 15.4W per PoE port. The PD devices, which have an operating voltage between 37V to 57V, can be connected to these switches.
VERSITRON also manufactures PoE+ switches that comply with the IEEE802.3at standard. Introduced in 2009, these switches also supply power over two pairs of cables and provide more power than standard PoE switches. These switches are used to connect devices, which may require more power than regular applications like several wireless applications. These switches can deliver 25.5W per PoE port and can accommodate PD devices in the operating voltage range between 50V to 57V.
What are the components of PoE/PoE+ Switches?
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 is the PoE transmission where there is absolutely no need for an additional power supply from PSE to PD.
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 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.
How does a PoE/PoE+ Switch work?
A power over Ethernet (PoE) switch configuration is easy to understand, owing to its simple construction. The switch features several Ethernet ports to ensure that power is provided to the networking devices connected to it. These switches may be operated in any of the following configurations:
Mode A Configuration: In this configuration, the switch delivers power and data through the same wire.
Mode B Configuration: In this configuration, the switch delivers power and data through different wires.
VERSITRON currently offers managed PoE/PoE+ swtiches.
Which Devices Can be powered by PoE and PoE+ Switches?

Remote Terminal Computers
Door Access Systems
Point-of-Sales (POS) network terminals
Back office servers
Our PoE+ switches are suitable to use for powering the following high-wattage devices:
Speed dome cameras
Audio Networking Systems
What are the Features and Specifications of PoE/PoE+ Switches?
PoE/PoE+ switches are gaining in popularity over other types of devices because they help simplify the installation and complex layouts in expanding networks. 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 are distinguishable due to the following features.
Our high-end managed gigabit Ethernet switches (10/100/1000) can transmit Ethernet, Fast Ethernet, and Gigabit Ethernet transmissions effectively.
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.
Our standard PoE Ethernet switches are compatible with Cat5e and Cat6 twisted-pair cables
Our SFP integrated Gigabit PoE+ switches are compatible with single mode, multimode, simplex, or duplex types of fiber optic transmission.
PoE or PoE+ switches offer better adaptability since this equipment can be transferred to any remote location without an active source of power supply.
The PoE and PoE+ switches feature copper-fiber compatibility with in-built SFP ports which makes them suitable for hybrid Ethernet networks.
These switches support jumbo frame transmission which enables the transmission of bulky data files.
The port mirroring or switched port analyzer (SPAN) feature of these PoE switches allows replication of data packets sent to different devices over a VLAN network.
Virtual stacking management (VSM) feature in our PoE/PoE+ switches enable centralized management, monitoring, and control over functions of multiple switches in a network.
Our switches support STP and RSTP protocols which improves their port capabilities such as discarding and forwarding data packets.
The switches encourage multicast VLAN registration (Port-based and 802.1Q tag-based LAN)
Our PoE switches support spanning tree protocol which prevents data loops in case of redundant paths in the network.
Link aggregation control protocol (LACP) supported by VERSITRON’s PoE switches allows establishing an LACP data unit connection between two devices in a network.
We offer full-time support and maintenance to the customers, therefore, maintenance and troubleshooting are no hassle for our buyers.
