4E1 + Ethernet Fiber Optical 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 1-4E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light and operation is convenient and credit.
It uses the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the macromedia or the special network. Complete alarm function for 1-4E1 Fiber Optical Multiplexer, it is stable and easy to maintenance, install and small in size. It has one digital service telephone.
n Base on IC of independence intellectual property rights
n Adopt veneer structure
n Offer 1-4 ×2Mb/s digital interfaces
n Up to 4 E1 links on one fiber
n One link to service telephone for duty contract
n Provides one channels of 10M/100M, support VLAN.
n One channel OA for optional.
n 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.
n 1U/19inch type model can provide SNMP network management port independently. It can also support cascade management. (optional)
n User can become conscious of the temperature and voltage of the local device in SNMP managing interface. (Optional)
n 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)
n 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
n Standard 19 inches rack, little volume, light weight, steady capacity and convenient setup
