Description :

The device is an Ethernet IEEE 802.3 media converter that enables the conversion of 100 Mbps optical Ethernet to 4 100 Mbps Ethernet, along with support for one RS232/422/485 serial port.

Overview

This device is an Ethernet IEEE 802.3 media converter that enables the conversion of 100 Mbps optical Ethernet to 4 100 Mbps Ethernet, along with support for one RS232/422/485 serial port. It supports transmission distances of 20/40/60/80/120 kilometers.

 

It is based on an Ethernet switch chip and FPGA solution, equipped with powerful local and remote management capabilities, this device can be integrated into a layer-3 network management system alongside 4*optical to 4*Ethernet devices and 1*optical to 1*ethernet with RS232 devices. It features comprehensive alarm functions, ensuring stable and reliable operation, low power consumption, high integration, and a compact form factor.

Features

● The device features an industrial rail-mounted design, specifically designed for harsh industrial environments.
● The device provides 4 100 Mbps Ethernet ports, 1 RS232/422/485 serial port, and 1 100 Mbps optical port, with a total transmission bandwidth of line-rate 100M.
● The ethernet ports support 10/100Mbps auto-negotiation and MDI/MDI-X auto-adaptation without the need for manual adjustment.
● It incorporates an automatic power-off and system reboot function in case of optical module failure.
● The device has a built-in 512Kbit MP-SSRAM high-speed memory, non-blocking design, and features such as automatic reset in case of system freeze, making it suitable for high-bandwidth data applications such as video transmission.
● Based on FPGA+ARM design, the device offers powerful local and remote management capabilities and can be connected to 2U card-insertion devices. It can also be configured with an SNMP network management card for management.
● It supports VLAN long packet transmission and can be used in conjunction with switch products that support IEEE802.1Q protocol, enabling support for Ethernet packets up to a maximum of 10K bytes.
● The device provides functions such as broadcast storm protection, flow balancing, collision isolation, and error detection.
● The Ethernet and serial data interfaces are protected against lightning strikes, meeting the GB/T17626.5 (IEC61000-4-5) short-circuit current wave 8/20μs and open-circuit peak output voltage 6KV standards.
● It offers 1 RS232/485/422 interface, with an optional RS232/485/422 channel that allows for the transmission of asynchronous serial data at baud rates from 0 to 115200.
● The network management feature allows real-time viewing and management of the interface status and settings for both the local and remote Ethernet.
● The device has a power failure detection function that can detect power loss to the remote device or fiber optic failure when the optical signal is lost.
● It supports a wide range of 9-55V AC and DC power inputs.
● It supports internal isolation and redundant dual power inputs.
● The power supply is equipped with overload protection and reverse connection protection.
● It complies with industrial-grade electromagnetic compatibility requirements.
● It provides excellent lightning protection, making it resistant to lightning strikes, high voltage induction, surge protection, and other related issues.
● With a fanless design, it ensures efficient heat dissipation and reduced repair time.
● The device is enclosed in an anodized aluminum alloy housing, providing an IP40 protection rating. It is capable of withstanding the challenges posed by harsh environmental conditions.
● It can be installed either on a rail or wall-mounted.
● It is designed to operate within a wide temperature range, from -40°C to +85°C.
● The device has passed the 100% burn-in testing and comes with a 5-year warranty period.
