    Gigabit Power Over Ethernet Plus Injector, PoE+ (30W) Power Network Distances Up To 100M, Black

    Product Description

    The Gigabit POE Injector allows flexible installation of Wireless Access Points by providing an alternative to external DC power when deploying a Power over Ethernet (PoE) switch is not an option. The PoE power injector has two RJ45 network interface connectors one RJ45 interface connects to a switch or a network device, and the other is used to transmit network data and supply power to the Power Sourcing Equipment (PSE).

    By combining data and power over a single Cat5e or better cable, the injector can also be used to supply connectivity and power to other PoE endpoints such as IP phones and IP cameras, in order that makes it more flexible for the places difficult to connect to the power supply and provide with more efficient solutions. For all the function featured in SN-PSE302G, people can get the benefit of flexible network installation at lower cost, less downtime. It also provides a high-bandwidth pipe to the network.

    PoE Applications Explained

    PoE Standards

    The original PoE standard, known as IEEE 802.3af, allowed 15.4 watts of power to be sent from a switch port. After cable resistance losses, each PD was guaranteed to receive at least 12.95 watts.In 2009, the IEEE 802.3at standard (also known as PoE+) was released, doubling the power per port to 30 watts. More recently, the new IEEE 802.3bt standard (PoE++) was formalized, allowing a massive 90 watts of power.

    The Advantages of PoE Technology

    Power over Ethernet (PoE) technology uses network cables to transmit data and power to devices. This means that a single cable can fully support devices such as wireless access points, VoIP phones, IP cameras and IP TV decoders.PoE eliminates the need for power cables and reduces cabling costs.The benefits of PoE include.

    • Reduced infrastructure costs

    Transmitting power and data over cables makes it much cheaper to install a PoE system compared to traditional wiring.PoE also allows for easier and cheaper outdoor installation.

    • Safer than traditional outlets

    PoE has fewer installation steps and fewer electrical hazards.PoE also reduces the risk of power outages, potential damage to equipment, and electrical overloads.

    • Enhanced Flexibility

    PoE power supplies and devices are plug-and-play and highly configurable. This makes it easy to add or remove devices without interrupting or disrupting the entire system.

    • Flexible centralized management of networked devices

    PoE-controlled devices can be disconnected and reconnected to a new PoE system with minimal downtime.PoE systems provide better control for smart buildings and ip-based security systems.

    • Greater Scalability

    PoE networks can be easily expanded when more devices need to be added in new locations.

    What is the difference between IEEE 802.3 af and IEEE 802.3 at?

    The difference is the amount of power that can be delivered. IEEE 802.3af supports 15.4 watts over Ethernet cables. IEEE 802.3at can deliver up to 30 watts over Ethernet cables.

    How does Power over Ethernet work?

    In PoE, Ethernet cables are used to transmit power to the device, and PoE devices require no additional wiring during installation. Initially, PoE was primarily used for Voice over Internet Protocol (VoIP) telephony, which allowed existing IP networks to carry voice data. As PoE became more popular, security cameras became one of the most abundant PoE devices on the market. Later, as wireless connectivity became ubiquitous, wireless access points entered the PoE world.

    Does PoE need special Ethernet cable?

    No. PoE uses standard Cat 5 Ethernet cables to deliver both power and data.

    Do I need PoE or PoE+?

    This depends entirely on the type and nature of the PoE device you want to use. The original PoE standard (IEEE 802.3af) allowed 15.4 watts to be sent from a switch port. Taking into account cable resistance, each device was guaranteed to receive at least 12.95 watts. The updated IEEE 802.3at standard (also known as PoE+) doubles the power per port to 30 watts.

    Newly powered devices are taking advantage of this advancement and require more power than ever before. Even if your current devices only require the standard power of 802.3af, you should consider the types and requirements of devices you will add in the future.802. This may be a viable path to take!
