4E1+4ETH PDH Multiplexer

4E1+4ETH Fiber Optic Multiplexer is the 1~4E1 point-to-point optical transport equipment that uses the FPGA chips and it is easy to upgrade. It is single board structure and the largest transmission capacity is 4E1 and 4*100M line Ethernet data, one channel RS232 (Optional). The Ethernet bandwidth is set on base on multiple of 32K.The outer design use the standard 19 inches rack, so the volume is small, weight is light and operation is convenient and credit.

Description

4E1-4Ethernet Fiber Optical Multiplexer can multiplex to 4E1 signals for transmission over an optical fiber, resulting in reaching a longer distance without a repeaters and superior performance compared to copper media.

 Product Characters

Base on IC of independence intellectual property rights

Adopt veneer structure

Offer 1-4 ×2Mb/s digital interfaces

Up to 4 E1 links on one fiber

One link to service telephone for duty contract

Support fiber redundancy function, there is two fiber ports, when one fiber is off, another fiber will connected automatically.(optional)

Provides 4 channels of 10M/100M, support VLAN setting.

One channel OA for optional.

RS232 channel for optional.

When fiber signal is loss, users can distinguish whether the remote device is power off or the fiber line is down from the indicator status on the local device.

1U/19inch type model can provide SNMP network management port independently. It can also support cascade management. (optional)

User can become conscious of the temperature and voltage of the local device in SNMP managing interface. (Optional)

User can also become conscious of the temperature and voltage of the remote device in SNMP managing interface, and can set the alarm threshold of the remote device’s temperature. (Optional)

180-260VAC & -48VDC power options and the positive and negative of DC-48V can be optional because there is the self-test circuit for the polarity inside th1e device

Standard 19 inches rack, little volume, light weight, steady capacity and convenient setup
