The POE-SFP100 is a high-performance Gigabit Ethernet Small Form-Factor Pluggable (SFP) module designed to convert fiber-optic SFP ports to RJ45 copper interfaces, supporting 1000BASE-T data transmission over standard Cat5e or Cat6 cables up to 328 feet (100 meters). Fully compliant with the Multi-Source Agreement (MSA) and IEEE 802.3/802.3ab standards, this module enables seamless integration with a wide range of switches and network devices requiring copper uplinks. Featuring a compact RJ45 connector assembly within a robust fully metallic enclosure, the POE-SFP100 ensures low electromagnetic interference (EMI) and reliable signal integrity. The device supports RX_LOS (Receiver Loss of Signal) link indication for enhanced network diagnostics and features low power dissipation, typically 1.05W, to maintain energy efficiency in network deployments. Designed with a hot-pluggable SFP footprint, the module allows for easy installation and removal without powering down host devices. It provides access to physical layer integrated circuits via a 2-wire serial bus and stores detailed product information in EEPROM for device management. Suitable for a broad temperature range, including commercial (0°C to +70°C), extended (-10°C to +80°C), and industrial (-40°C to +85°C) environments, the POE-SFP100 is ideal for reliable copper connectivity in diverse networking applications.
