PLANET LRP-104CET – Industrial 4-Port 10/100TX PoE + 1-Port Coax Long Reach PoE Extender

SKU: 4713 Category:



PLANET Long Reach PoE solution is designed to extend IP Ethernet transmission and inject power simultaneously into a remote 802.3af/at PoE compliant powered device (PD) beyond the 100 meters distance limit of Ethernet.

Perfect 1-to-4 PoE over Coaxial/UTP Extender in Harsh Environment
The LRP-104CET, a PLANET Long Reach PoE solution, is an industrial-grade Single-port Long Reach PoE to 4-port 802.3af/at PoE Extender delivered in an IP30 rugged strong case. It features long-range data and power transmission over any existing coaxialUTPtwisted-pair cable or telephone wires for distance up to 1,000m and converts power to standard 802.3af/at PoE over another 100-meter Ethernet cable connected to four remote PoE PDs at the same time. The LRP-104CET provides one to multi applications for configure-free operation and deployment in climatically demanding environments with wide temperature range from -20 to 70 degrees C. It makes the installation of remote PoE powered devices easier and more efficiently.


IP Ethernet and Power over Long Distance
The LRP-104CET provides a Long Reach PoE solution for adding PoE ports without running more cabling and achieves more flexible network applications without requiring an external power adapter.

A normal UTP cable can only be extended up to 100 meters, but with the LRP-104CET, the distance for PoE networking can be extended up to 1,000 meters (3,280ft.) when functioning with PLANET LRP injector or LRP switch over 75 ohm coaxial cable or up to 500 meters (1,640ft.) over twisted-pair UTP cable, without affecting the quality of video transmission. Thus, it eliminates the need for an additional electrical outlet as its single power source can provide power to a PoE PD at long range via the LRP-104CET.

Two Types of Power Input: Remote LRP Power through BNC/RJ45 and Local Power
In the Long Reach PoE mode, the LRP-104CET‘s PoE budget depends on the output of the Long Reach Poe Injector or Long Reach Switch, but with External DC Power input, it is possible to increase the PoE budget up to 120W. It means the four IEEE 802.3at PDs (powered device) can be powered by the LRP-104CET. It also features a strong dual power input system (Dual 24V~48V DC) incorporated into customer’s automation network to enhance system reliability and uptime.

Configure-free Installation
The LRP-104CET can be used immediately without the need of configuration and is also compliant with all kinds of IP network protocols. Moreover, the rich diagnostic LEDs and PoE Power Usage LEDs on the front panel show the operating status of the individual port and the whole system. The DIP switch can control PoE output of each port by turning ON or OFF, enabling the administrator to efficiently manage the network.


Stable Operating Performance under Difficult Environments
PLANET Long Reach PoE Extender is the perfect solution for extended data and power transmission for warehouses, parking lots, campuses, casinos, and many more. It can operate stably under temperature range from -20 to 70 degrees C which enables the users to conveniently apply the device in any harsh environment. Without the problem of power source, it makes the installation of remote PoE powered devices easier and more efficiently.
