Product Overview

The SF303RP PoE Passive Switch is a robust optical transceiver designed to deliver efficient data transmission and power management. It features 3 fiber optic ports operating at 155 Mbps and 3 Ethernet ports at 10/100 Mbps, with two of these Ethernet ports supporting Power over Ethernet (PoE). This design effectively addresses the challenges of powering customer access equipment in specialized environments, simplifying installation and maintenance while reducing power provisioning costs and operational workloads.

Key Features

  • 3 x 155 Mbps fiber optic ports and 3 x 10/100 Mbps adaptive Ethernet ports for versatile connectivity.
  • Ethernet ports support half/full duplex10/100 Mbps auto-negotiation, and automatic MDI/MDI-X functionality for easy integration into existing networks.
  • Ultra-wide input voltage range of 15~48VDC to accommodate diverse power requirements.
  • Capable of outputting 12V/1A to power additional devices via a convenient DC socket.
  • Ethernet ports can receive power using spare pairs (4/5+ and 7/8-) for flexible device integration.
  • All ports support wire-speed forwarding for smoother and more efficient data transmission.
  • Equipped with comprehensive indicator lights for both optical and electrical connections to facilitate installation and maintenance.
  • Supports both desktop and wall-mounted installation for adaptable deployment options.
  • Utilizes low-power consumption chips to enhance energy efficiency.
  • Plug-and-play design ensures easy operation with no configuration required.
  • Constructed with a metal housing that provides excellent heat dissipation, ensuring stable operation over extended periods.
