4-Port 100Base-TX to 100Base-FX Media Converter (1+1 Fiber Backup)
This device provides 4 ports 10/100M Fast Ethernet and 2 ports 100Base-FX.
Overview
Features
● The device provides 4 100Mbps Ethernet ports and 2 100Mbps optical ports.
● It provides a primary fiber interface and a backup fiber interface, ensuring uninterrupted service through dual-fiber redundancy.
● Both optical ports are equipped with OAM management frames, which can indicate the status of remote devices.
● The Ethernet ports support auto-negotiation for speed and duplex mode and support AUTO-MDIX.
● The 4 100Mbps Ethernet ports can be configured for logical isolation, allowing independent transmission of four sets of network services on the same fiber line.
● It supports the transmission of jumbo frames and is fully compatible with forwarding various extended protocol data frames.
● The optical interfaces support multi-mode dual-fiber, single-mode dual-fiber, and single-mode single-fiber transmission modes, with optional SC/ST/FC/LC interfaces.
● It features a variety of status indicator lights, providing convenient and accurate information about the device interfaces and link statuses.
● The Ethernet interfaces are equipped with three-level lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) short-circuit current wave of 8/20μs and peak output voltage of 6KV.
● The device supports multiple power supply options, including AC220V, DC-48V/DC+24V, and DC+V12.
