Single Port PoE Ethernet Extender - Surveillance

Gem Electronics
Part Number POE-PL602
Single Port PoE Ethernet Extender
POE-PL602 Single Port PoE Ethernet Extender is a high-speed Ethernet transmission device.
It can transmit Ethernet and Power signals together for PoE devices. It transmits data network signal
up to 1,000 meters over any pair of 2-wire such as Cat5, coaxial cable and power line, etc.
The maximum physical bandwidth can reach 200Mbps.
It supports PoC and PoE functions.
It consists of the master unit and slave unit. By PoE power equipment, it can directly supply power for the remote unit,
supporting point to point and point to multi-point. It can greatly simplify the project cabling, applied to expand network
system and transmit long distances of PoE device signals.

POE-PL602 supports enhanced high speed network data transmission. The data differs from the cables types.
Moreover, the longer distance of cable, the lower the transmission rate accordingly. The following testing details are for
your reference:
Figure (1)
The above data is one-way network parameters. Testing is made under the condition of the cable not fully expanded.
There may be differences compared with practical application of the data. Rate is only used as reference in project
Network & Power can be transmitted over 2-wire. The total PoE power output is 30W(at) and it can be attenuated when
transmitting through cable. Distance is longer, attenuation is more.
Power loss and attenuation differs from the cable types. The following PoE power distance chart is just for your

Tips: In the above figure, the left vertical coordinate is PoE power output, the below horizontal coordinate is PoE
transmission distance, please simultaneously contrast the horizontal and vertical coordinate to get accurate
corresponding power output.

1. Provide PoE Power Supply for front-end PoE device (The device only supports PoE Output, don’t support PoE
Page 5 of 6
2. Provide low voltage 12VDC for front-end device.
3. When transmission distance is long, to avoid output voltage dropping too much, also provide 48~56VDC power
supply for slave unit, at the same time master unit also get power from it.
4. When connect 12VDC power supply for master unit, because long distance causes output voltage to drop too much,
it can’t satisfy slave unit power requirement, also provide 12VDC power supply for slave unit as supplement.
Tips: The power consumption supports PoE / Non-PoE equipment power supply standard, due to the difference of line
loss and transmission distance, it may not be able to meet simultaneously two kinds of power supply requirement, only
through dip switch setting to choose one kind of power output mode.
When you use POE-PL602, please follow the below tips as a reference, in order to reduce the fault in the process of
using and the inspection work.
1. The device supports auto-negotiation allocation master and slave. It also can be set master-slave side and grouped
by the software. Each group (one point to multi-point communications group) only allows one Master, others are Slaves.
Otherwise, the network data won't be able to transmit.
2. Signal transmission cable must be the copper cable. Other material cables will cause the decrease of signal
transmission quality and distance.
3. Long-distance cable connections must be by standard connection method, such as welding or using connectors.
4. Make sure the electrode of transmission cable is consistent, otherwise, it is easy to cause the power failure.
5. Please choose matching power adaptor (12VDC or 48~56VDC).
6. There is no waterproof design for this product, please make sure that it is used in dry environment.
7. If device fails, do not disassemble or repair it by yourself. Please contact us timely.
