Modern IP-based networks, which map parallel services on a network infrastructure (computers, but also VoIP or WIFI applications), are designed for power supply via PoE or PoE+ (according to IEEE 802.3at, downward compatible IEEE 802.3af). This is mainly driven by the large number of compact end devices. There is no need for a separate power supply; a 230V socket and separate cabling are not required.
For simple 1:1 media conversion with additional PSE (Powered Source Equipment) supply, MICROSENS has special PoE bridges in its product portfolio that are designed in the typical desktop design.
The main features of these devices are
- Conversion / bridging from 10/100/1000Base-T (RJ-45 with PoE+ PSE function) to
- the Dual Speed fiber optic SFP slot (100/1000Base-X, depending on SFP type)
- the direct 230VAC power supply without an external power source (integrated power supply unit)
- the adjustable Link Fault/Pass Through function.
The adjustable LFP function contains a simple but extremely effective mechanism for IT administration. To reset the PoE-fed terminal device, only the interruption of the fiber optic connection to the bridge is necessary (this bridge is typically connected to a centrally administered access switch). As soon as the fiber connection is briefly interrupted by management access, the bridge in LFP mode can also forward this interruption to the TP port and the PoE power supply. If the PoE supply is briefly interrupted, the terminal restarts.
The compactness of the desktop PoE bridge is also worth mentioning; the power supply unit for the bridge and the PoE+ terminals is integrated in the housing. An external power supply is not required.
