Need to deliver power and data 300m away, and you only have a coaxial cable to do it?
Advantech might have just the thing for you, with its IMC-150LPC PoE (power-over-Ethernet) extender.
“This device uses extant coaxial cables and and makes the IMC-150LPC an excellent choice for industrial and rail network infrastructure upgrade projects with limited power and network resources,” according to the company. Its “capabilities are buttressed by an LFPT mechanism that augments transmission quality.”
LFPT is ‘link fault pass through’, a troubleshooting feature designed for media converters, available when a pair of the devices are used, one at each end of the link – there are actually two parts: EKI-150LPC-M (master) and EKI-150LPC-R (remote).
When enabled, LFPT serves to prevent data loss by taking action during link failure incidents, and will pass a link fault through the device at each segment. “For, example if the link fails on one IMC-150PLC, the other IMC-150LPC will force the link down on its link partner and avoid data loss,” said Advantech.
Ethernet cables up to 100m long can be used on the other side of the boxes, and up to 100Mbit/s is possible through the coax along with >15.4W of power – the company sees the devices being used with IP cameras.
Size is 25 x 80 x 85mm plus connectors, operation is specified over -40 to 75°C and it is EN50121-4 EMC certified. 300m range is specified with RG59 coax.

A compatible 120W power adapter (XIMC-FSP120-AWAN3) is sold separately
