PoE Expansion with One Cable

As the development of Internet of Thing (IoT) under this tech-orientation era, network devices are indispensable and are commonly used in business and home, such as IP camera, Wireless Access Points(WAPs), VoIP phone and so on. Additionally, some of them are PoE-enabled devices, also called PoE powered devices. Therefore, you might be more or less faced with expansion issue for your existing networking infrastructure because of the unexpected grow-up demand of multiple network devices at places where hard to find or deploy AC outlets and network ports, such as pole, garage, and backyard etc. That said, multiple RJ45 ports are required in this scenario. While some even want to get network and power expanded with one network cabling. Then what to do? Today, let’s focus on a practical and advanced product named PoE Powered Pass Through Switch, this might give you a feasible solution.

By implementing this device, you are capable of using one cable to realize the PoE expansion, in other word, there is no more complicate cabling, saving time and money. One thing to be noted that this “one cable” doesn’t mean you only need to one single complete cable, which is impossible as the pass through switch requires two ends connection at least. So this “one cable” only indicates one cabling is needed between the pass through switch and main network(switch or PoE injector). You might be still confused about how the device really gets your problem solved in an economic and convenient way. Keep reading and you are going to be enlightened.

In order to let you know the solution of “PoE Expansion with One Cable” more easily and clearly, we’d better go through how the general methods that float in your mind work to grant power and network to your multiple network devices. Provided that you have a PoE switch equipped with 8, 16 or 24 ports at home or office, then you may need to run Ethernet cables separately for each network device located within 100 meters from the main network. Besides, what if the network devices waiting for PoE connection are located beyond 100 meters, then some PoE extension devices are necessary, such as PoE extender, which offers you a maximum of 500m PoE connection, dealing with the issue of PoE’s 100 meters transmitting limit. These two methods are definitely cost more on network cable and take up more RJ45 port of your main network (PoE switch or PoE router). Or additionally you are likely to choose to add another PoE switch in the middle of your main network and network devices. This is an alternative choice for a PoE connection that is less than 200m, but meanwhile a 220V power source should be easily found near the switch. All in all, these methods are available and viable if you think less on installation complexity and deployment fee.

On the contrary, PoE Expansion with One Cable solution works more simply by using the PoE pass through switch with its high performance technology integrated in one single device, which receives standard PoE or PoE+ (power and data) from the back-end main network and pass through to the front-end network devices under a lossless connection.  


No AC outlet is required at the deployment site.

Unlike those common approach considered in your mind, this solution makes great use of PoE technology, it features PSU and PD integrated in one single device, namely, it doesn’t call for a necessity of AC outlet (220V power source) that close to. The reason is like we talked previously as its pass-through function, and thanks to PoE, it enables one Ethernet cable to carry power and data simultaneously to extend PoE for another 100 meters. This is perfectly solved some kinds of essential problems of lacking AC power source at remote deployment site. That said, it saves a lot of work and investment before connection, as you know network and wire cabling is not so easy for yourself to handle, so you need to hire professional electricians in most cases.

Sufficient Power and Fast network

You are opt to get a maximum of 4 or 7 IP devices powered up and gained gigabit network to ensure smooth and fast data streaming. Besides, as the pass through switch supports IEEE 802.3 at standard, offering up to 30W per port, so IP device with high power consumption can still get sufficient power. Additionally, sufficient power budget would be a main problem for supplying multiple IP devices from a single device. While this solution is perfect to ease back-end power supply when it is coupled with our 95W PoE injector, the pass through switch can receive up to 71W remained power and forward to front-end multiple devices.

Easy and Flexible Installation

By using this device you are allow to realize PoE expansion with simple steps. Just need to plug the Ethernet cable into RJ45 ports, then power and network can be delivered safely and stably to your PoE powered devices, no configuration is needed. Wall mount or din rail mount are optional for you to choose according to your requirement. Its compact design provide flexibility to install in confined space. Furthermore, take advantage of its qualified rugged component, and use with a combination of waterproof enclosure, you are able to place it at outdoor, where is not directly expose under sunlight, such as under the eave. Or you can just use the outdoor PoE passthrough switch that specially designed for outdoor installation.

You see, this one cable PoE expansion solution is truly practical and hassle-free to make IP device gain power and network easily, especial in your potential grow-up demand for adding new IP devices. Once the system set up, just need to plug a cable to add one IP device into your network system.
