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 “S” 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.
