A Beginner’s Guide to Multi-Gigabit Power over Ethernet (PoE)

Multi-gigabit power over Ethernet (PoE) combines the high-speed capabilities of multi-gigabit Ethernet with PoE’s convenience to supply data and power over a single Ethernet cable. A robust and efficient solution for modern networks, the benefits of multi-gigabit PoE include:

• Faster data transfer.
• Simplified deployment.
• Support for a more versatile range of applications.
• Enhanced network performance.
• Scalability and flexibility.
• Centralized device management.
• Cost-effectiveness.

This guide will offer an overview of the possible uses of multi-gigabit PoE and what hardware will help users get the most out of it.

What is multi-gigabit PoE used for?

Multi-gigabit PoE supports data rates beyond 1 Gigabit per second (Gbps) with numerous applications, including:

• Access control devices.
• Digital signage.
• IoT devices.
• Surveillance cameras.
• PoE lighting.
• Remote kiosks.
• Wi-Fi 6/6E access points.
• IP cameras.
• Wireless access points.

This setup allows for simultaneous data delivery via gigabit connections to multiple devices, with speeds over 1 gig up to 10 gigs. It is beneficial for supporting demanding applications like cloud computing, video conferencing, and IoT deployments in enterprise networks. Data centers can benefit tremendously from incorporating multi-gigabit PoE capability in their facilities.

Do I need a multi-gigabit switch?

Speed, efficiency, and scalability requirements will determine whether you need a multi-gigabit switch. However, even if businesses don’t need multi-gig support now, it’s still worth considering a multi-gig switch, as having one can future-proof your network. 

A standard switch typically supports Ethernet connections of up to 1 Gbps. A multi-gig switch can accommodate internet speeds beyond 1 Gbps. An upgrade to a multi-gigabit switch doesn’t necessarily mean an increase in the number of ports; it signifies that each port can sustain higher throughput.  Also, not all ports within a single multi-gig switch will provide the same power or speed capacity level. It allows device connection according to speed requirements and task nature.

Multi-gigabit PoE switches supporting a variety of network speeds are available.

2.5G Switches

Ideal for small offices, 2.5G switches can support multiple 4K video streams and simultaneous HD videoconferencing.

5G Switches

Suited to small and medium-sized businesses with heavy online activities, 5G switches enhance productivity for video production companies and graphic design firms by speeding up large file transfers.

10G Switches

Ideal for data storage centers and large enterprises with intensive data needs, 10G Ethernet switches enable rapid data analytics and cloud operations. These switches support high-traffic volumes for data centers that host multiple online services.

A single switch might feature one 10G Ethernet port, one 5G Ethernet port, and several 2.5G Ethernet ports. With this highly efficient and flexible networking setup, you can connect a Network Access Storage (NAS) system to the 10G port, transfer large files via the 5G Ethernet port, and connect a desktop computer to the 2.5 port for streaming.

If your business only requires a handful of devices and your internet service plan doesn’t exceed 1G, investing in a multi-gigabit switch may not be necessary. For a higher level of capability, with speeds of up to 10G, a multi-gigabit PoE switch is a must.

Environments Demanding Higher Transfer Rates and Volumes

Commercial environments and institutions are some of the biggest beneficiaries of multi-gigabit PoE. The most common are those that demand higher transfer rates and volumes.

Data Centers

Multi-gigabit PoE can provide the bandwidth required by high-performance storage systems. This technology supports increased network demands in high-density server environments to ensure efficient data transfer and management.

Enterprise Networks

Providing the flexibility and bandwidth needed to support demanding applications of enterprise networks, multi-gig PoE helps enable:

• Cloud computing.
• Video conferencing.
• IoT deployments.

Multi-gig PoE helps connect and manage large numbers of IoT devices within a single system, such as cameras, sensors, and automation systems. High-quality audio and video transmission is possible in conference centers and large meeting rooms.  

Healthcare Facilities

Modern telemedicine applications such as real-time video consultations with patients and data transfer between health providers require secure, reliable, high-speed connectivity. High-resolution imaging equipment like MRI and CT scans require a lot of bandwidth to deliver superior image quality.  

Educational Institutions

Multi-gigabit power over ethernet enables the seamless integration of student collaboration tools, multimedia content, and videoconferencing used in interactive classrooms. It also provides fast access to the extensive digital collections and resources digital libraries offer.

Hospitality Industry

In hotels, this technology can connect and power smart hotel amenities like TVs, lighting systems, and climate control. It also supports the high-bandwidth requirements of conference centers.

Retail Centers

Point-of-sale systems depend on the fast and reliable transaction processing multi-gig PoE can provide. It can also power high-resolution digital signage devices to provide customers with information and advertising.

Manufacturing Centers

Manufacturing facilities can use multi-gigabit PoE for industrial automation to remotely monitor and manage operations on the factory floor. Surveillance systems can leverage the power and convenience offered for better security and improved quality control.

Transportation Hubs

A valuable asset to transportation hubs, multi-gigabit PoE enhances connectivity and efficiency. Specific applications for the technology in transportation hubs include:

• Digital signage to provide travelers with real-time updates.
• Wireless access points to supply high-speed Wi-Fi connectivity to passengers.
• Surveillance systems to detect anomalies like suspicious behavior or unattended baggage.
• Building automation systems to power sensors that monitor energy consumption, security devices, and access control systems.
• IoT applications can facilitate smart parking infrastructure and asset tracking.

Transportation hubs can create a more secure, efficient, and connected environment for travelers and staff by incorporating multi-gigabit PoE.

Is special cabling required for multi-gigabit PoE?

Multi-gigabit PoE delivers blazing-fast performance and support over existing cable. Cat5e, Cat6, and Cat6A wiring are sufficient for optimal operation. This convenience eliminates added expenses and reduces the complexity of installing new cabling infrastructure.
