Long distance network transmission always confuses us. As we know, network signal transmission is limited by copper material. If using cropper cable to transmit network over 100 meters, the signal would become too weak to support devices working.
With convenient network, we are able to set up IP camera system to improve security safety. In the case of building A to building B, backyard to garage, warehouse to home, firstly it should have network connectivity there. In some situation, we may have to consider the power as well. Electronic equipments such as IP cameras, access point VoIP, not only need data but also power. In order to guarantee the devices working well 24/7, reliable and convenient network with power system are very essential.
The article would show 3 ways to extend network from one place to another. If you want to extend network between 100-500 meters, the first solution is right choice to go. If longer distance is required, like home to farms, the last 2 ways has provided some useful ideas.
- Long distance up to 500 meters.
In this way, we can use PoE products to extend network up to 500 meters. It allows us to extend network distance like home to backyard warehouse.
1. PoE switch
2. PoE extenders
3. Cat5e cables
You may confuse what is PoE and how it helps to extend network? PoE, power over Ethernet, is a technology that transports data and power over single Ethernet cable. That’s mean we do not need to prepare extra power adaptor which will reduce cables and simplify installation.
How it works? PoE switch transports data and power to front-end IP devices. It always has power source equipment such as PoE switch or PoE injector at back-end. These PoE switch or injector will send the power and data to the extender, the PoE extender catch it and boost up for next 100 meters. 4 units PoE extenders link together with daisy chain setup can provide totally 500 meters PoE network.
Firstly, we need one PoE switch port to connect to PoE extender. Now the PoE extender gets data and power which will transport both of them to IP device or next PoE extender with Cat5e/cat6 cables.
If we need to expand RJ45 ports at the front end, we can use pass through PoE switch. Similar as PoE extender, pass through PoE switch is powered by a PoE injector at back-end, and create multiple PoE ports for remote ip devices. As the latest IEEE802.3bt standard is employed, the pass through PoE switchsupply total power budget up to 71W.
- Long distance up to 80KM （Power from front-end）
1. PoE switch
2. Fiber cable
3. Media converter
4 .Ethernet cables
If the power source is available at the front end, what we need is the media converter to set up the fiber link network. The advantage of fiber optical cable is fast speed, low latency and long distance. It is basically the light transmission in the fiber cable. The fiber optical signal will be converted back to electronic signal and go through Ethernet cable after media converter.
Firstly, install SFP modules on PoE switch and media converter. If PoE switch has SFP slot, it saves one media converter. Otherwise, two media converters are needed at two building. The network system needs a converter to transfer optic signal into electronic signal.
Now use fiber line to link SFP and another media converter.
Finally we can connect the two building with fiber optical cable.
In addition, if we want to use media converter to back up multiple IP devices, we can connect the media converter to network switch. The switch would get data from converter and support data to multiple IP devices.
- Long distance up to 2.5km（Power from back-end）
This connection way is to solve the issue while the power source is difficult to acquire at front end. As we know, fiber optical cable does not deliver power and electronic devices need power to supply it work. In this way, building A would like to offer power as well as data.
1. Media converter
2. Fiber PoE extender.
3. Siamese fiber cable
Similar as above solution, it needs to set put fiber optical link between two buildings. The fiber optical can’t transport the power, however we can add one pair copper or Siamese fiber optical cable which has integrated copper cable to send the power in parallel. The voltage drop is the first issue for long distance power transmission. DC55-DC57V is properly voltage as it is safety to human being. After fiber PoE extender receives the power, it will boost up the voltage and regulate to DC48V output for front end PoE devices. Both non-PoE and PoE equipment can’t be connected to the fiber PoE extender at the other end. Constructed to voltage drop, the maximum meaningful PoE distance is 2500-3000 meters, the voltage will become too low to supply the PoE ip device, most of the power will be loss on the cable. The fiber PoE extender is convenient tool for long distance PoE network, where the network go, the power follow.
General speaking, if extends network from 2 building within 500 meter, user can choose PoE extender to repeater network. It is good choice for user to pick fiber solutions while extends network far from 2.5km. Click here and show Practical tips to improve your WiFi signal
