Modular Multi-service Fiber Mux | 16E1 PDH Multiplexer

View : 1,075
Type : 1-16E1 Fiber Multiplexer
Description :

The device provides 4 ethernet port and 2 AUX port which is for transmitting other data such as RS232/RS485/RS422,dry contact closure, two optical interface for optional 1+1 auto protection switch (APS).


This device is modular structure point-to-point optical transmission equipment with LCD display, uses FPGA chips, and is easy to upgrade. The Mainboard provides 4 ethernet ports and 2 AUX ports which are for transmitting other data such as RS232/RS485/RS422, dry contact closure, and 2 optical interfaces for optional 1+1 auto protection switch (APS).


4 slots of tributary with variant plug-in modules which included 4xE1 channels module, 4/8/16 x FXO/FXS module and 2x Nx64K V.35 module.The maximum capacity will be up 4 plug-in modules which could be combinations with the above modules. The high flexibility, and performance, is the best solution for voice/data/video services in the existing market.
