Detailed Product Description

Product  function: transmission of 4E1 and 4ETH signal through fiber
4 E1 is a family of FMO, this model it can multiplex to 4 E1 signals for transmission over an
optical fiber, resulting in reaching a longer distance without a repeaters and superior performance
compared to copper media.
4 E1is the 4 E1point-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 8E1. The outer design
use the standard 19 inches rack, so the volume is little, weight i s light and operation is convenient
and credit.
4 E1fiber Mulitplexer , is use the PDH fiber transmission technologies. The 2M (E1) interfaces
can connect with the exchanger, light loop device and multi-diplexer directly to form the mircomidi
or the special network. Complete alarm function for 8E1 fiber Mulitplexer, it is stable and easy to
maintenance, install and small in size. It has one digital service telephone.

Product Product Product characteristic: characteristic: characteristic:
 provides 8E1 The G.703 connection
 realizes long-distance monitoring of this end equipment to the far-end equipment (two-row
indicating lamp, upper row indicates local status, lower row indicates far-end status)
 provides function of ordering 4E1/8E1/16E1 to loop return from the remote end, fiber self-loop
at local end; and provides a group service telephone interface (to select)
 three power supplies: DC-48V, DC+24V or AC220V (optional)
 transmitting range: 2-120Km
 the double filament bidirectional and the single filament bidirectional type may select
 conforms to the telecommunication level operation
 requirement, and does not have the fault time equally (MTBF) above 100, 000 hours
 has the redundant reliability, provides installment of 19 "rack, desktop sets, the wall hanging,
and card-inserting, atthe same time 19" rack has the alternating and direct power supply.
 realizes the SNMP network management function.
