Industrial 4xRJ45 to 2xSFP POE Fiber Media Converter, 10/100/1000Base-T

This unit converts Gigabit Ethernet signals from copper cables to fiber cables. There are four POE RJ45 (Power over Ethernet) ports and two SFP fiber ports on this unit. POE provides power and data over a single cable to devices such as cameras or wireless access points. Each POE port provides up to 30 W of power according to IEEE 802.3af/at standards.

The converter operates reliably under extreme temperatures ranging from -40 °C to +85 °C. It can also withstand humidity levels from 5% to 95%, as long as there is no condensation present. The unit is housed in an aluminum enclosure rated IP40 for protection from dust particles larger than 1 mm and is cooled via natural airflow (no fans are used).

The converter receives its power supply through two 12–54 V DC inputs using Phoenix terminals. If either power supply fails, the other will automatically take over without interrupting power to the converter. The unit has short-circuit, overload, and reverse-polarity protection, and the total power consumption is less than 65 W.

Performance specifications for networks include a switching capacity of 12 Gbps and a forwarding rate of 8.93 Mpps. The converter has an 8K MAC address table with a maximum packet buffer of 1 MB and uses a Marvell chipset for processing. Mean time between failures (MTBF) is more than 100,000 hours.

The design also allows for easy installation on standard DIN-35 mounting rails (size 145 × 105 × 50 mm, weight approximately 1 kg). There are no configuration requirements, as this is an unmanaged unit. SFP modules are sold separately, and power adapters are available with EU, UK, US, BR, and AU plugs.
