    INTRODUCTION

 
  ZYEQ-480S is optical fiber transmission device based on the highly integrated VLSI FPGA, which is put forward by BZY Co.Ltd. This multiplexer has the maximum capacity of 480 B channel, corresponding to 16 E1 channels. This device performs with high availability, reliability and flexibility . These features make ZYEQ-480S the ideal equipment for building small or medium scale communication network and private network.

ZYEQ-DF480S has same functions as ZYEQ-480S, the extra function is ZYEQ-DF480S has two optic connectors which provide 1:1 optic transmit protection.
