Product information "NSM-205PFT Unmanaged PoE Fiber Switch, 4 x RJ-45 PSE + 1 x 100Base-FX ST"
The NSM-205PFT CR is an unmanaged Ethernet switch that combines four 10/100Base-TX copper ports with one multi-mode 100Base-FX fiber port. The four RJ-45 ports act as Power Sourcing Equipment (PSE), so one DC input can feed several IEEE 802.3af powered devices from a single cabinet. Each PoE channel delivers up to 15.4 W, and the switch automatically detects connected powered devices and manages their power.
The fiber uplink uses an ST connector and runs at 100 Mbps over distances of up to 2 km for full duplex operation, with 62.5/125 μm fiber recommended. Because the link is optical, it is well suited to cable runs where electrical noise could affect copper connections. The housing is metal and the unit mounts on a DIN-rail, with IP30 protection and an operating range of -30 °C to +75 °C.
Store-and-forward switching with IEEE 802.3x flow control, 1024 MAC addresses and 1500 Vrms isolation. The power input accepts +46 VDC to +55 VDC, with reverse polarity protection built in.
Applications
- Centralised power distribution to PoE-powered devices across an industrial site
- Extending Ethernet links over fiber where electrical noise is a concern
- Connecting remote Ethernet segments over multi-mode fiber up to 2 km
