2. Industrial-Grade Protection: Incorporates dual 4KV lightning/surge protection on both power and Ethernet ports, with a watchdog circuit for automatic recovery from faults.
3. Advanced Chipset & Management: Built with Marvell chipset supporting jumbo frames and auto-negotiation, plus DIP switches for configuring LFP, storm control, and port speed.
4. Wide Environment Tolerance: Operates in extreme temperatures from -30°C to 70°C, making it suitable for outdoor cabinets and harsh industrial applications.
Media Converter Description
This Gigabit Single-Fiber Media Converter is engineered for robust, long-distance network extension. It converts 10/100/1000BASE-T Ethernet to an optical signal for transmission up to 25km over one strand of single-mode fiber. Key features include industrial 4KV dual lightning protection, a watchdog auto-reboot function, and versatile DIP switch configuration. It is an essential solution for connecting remote IP cameras, extending campus networks, and building reliable FTTx backbones in challenging environments.
