NS-205PFT
Unmanaged Power over Ethernet Switch with SC Connector, 4-Port 10/100 Mbps PoE (PSE) with 1 Fiber port, Multi-mode. Supports operating temperatures from –30 ~ +75°C
Features
Introduction
The NS-205PFT is a 4-port unmanaged PoE (PSE) with 1 fiber port switch; it supports 4 PoE ports which are classified as power source equipments (PSE). The NS-205PFT makes centralized power supply come true and provides up to 15.4 watts of power per PSE port. Using fiber optics, you can prevent noise from interfering with your system and supports high-speed (100 Mbps) and high distance (up to 60 km) transmissions.
