 Product Description: 
 OE-4A 4E1 PDH Optical Multiplexer 
 OE-4A 4E1 PDH Optical Multiplexer is the company's private network based on the current market the rapid increase in user self-developed multi-functional PDH PDH network, the largest single four E1 interfaces can provide, especially for small communication capacity, reliable of demanding customers private network access. 
 The device performance as a mature technology products, both hardware and software within the modular structure. Circuit board on the use of architecture, hardware with a proprietary FPGA, set of codecs, digital smoothing lock is equal to one, so much better than the indicators ITU-T recommendations. Has been widely used in telecommunications, mobile, Unicom, electricity, railways, military, banks and other private communication online.
