Product Description

Introduction

This series of equipment is developed by the company PDH optical fiber transmission for ultra-large scale integrated circuit based on the development of point-to-point optical transmission equipment. It provides 1 ~ 16 E1 interface, 8*10/100M Fast Ethernet interface (wire speed 100M), and 2 extended service interface. 4*FE Ethernet interface for the exchange port, can support VLAN division. 2*extended service interface can be used as RS232/485 / 422 asynchronous data, the application is very flexible. Optional digital business phone, optional Console serial network management, optional independent SNMP network management.

Features

◆ Based on independent intellectual property rights of integrated circuits;

◆ Modular wide dynamic photodetector;

◆ Ethernet interface rate of 10M / 100M, full duplex / half duplex adaptive;

◆ 8*FE Ethernet interface for the exchange port, VLAN can also be divided into four channels can be set to logic isolation;

◆ With the Ethernet loopback function (when the optical line occurs when the loop, the Ethernet data will not be loop back, effectively prevent the Ethernet loop may cause the Ethernet network paralyzed);

◆ E1 interface in line with G.703 recommendations, the use of all-digital clock recovery and smooth phase-locked technology;

◆ Uses standard 2 wire telephone (non-telephone handles) set as engineering order-wire hotline(optional);

◆ Can detect when the optical signal is lost when the remote device power down or fiber unreasonable, and through the indicator light alarm;

◆ Have the function of displaying the remote device working status at the local end;

◆ Provide Console management interface, easy to install and open;

◆ Provide 2 expansion interface, optional expansion 1~2 asynchronous data, such as RS232/485/422/TTL; or 1 to 4 dry contact and so on;

◆ No relay transmission distance of up to 2 to 120 km;

◆ A variety of power supply options: AC220V, DC-48V / DC24V, etc .; support AC + DC; AC + AC; DC + DC dual power backup mode;

◆ DC-48V / DC24V power supply with automatic polarity detection, installation without distinction between positive and negative
