  PDH-CENTER Rack
 

    INTRODUCTION

 
  ZYEQ-PDH-CENTER is a centralized point-multipoint optical multiplexer which has a modularized machinery structure rack. There 16 slots for plug-in and pull-out modules in the rack and 15 of them are for the multiplex modules- JK120S JK240S and JK480S which have 4 E1 channels, 8 E1 channels and 16 E1 channels respectively and another 1 slot is for monitor module. At remote ends, all members in ZYEQ S family can be used to form a link via optical fibers.  

 

    MAIN FEATURES

 

Working status can be monitored by the watching computer in the upper layer in real time.

 

All the multiplex modules have Ħ°SĦħ optical ports.

 

Monitor up to 15 directions in real time.

 
Can be managed locally and remotely within the LAN.
 

JK120S and JK240S module can be used in ZYEQ-PDH-CENTER, while JK120S,JK240S and JK480S can be used in ZYEQ-PDH-CENTER- ?

 
Power supply: -48V, consumption <= 10W/per module.
