Detailed Product Description

DHODT-E  Modular PDH,FOM Fiber Optical  Multiplexer.

DHODT-E Series of Modular Integrated Optical Transmission Multiplexer is an optical multiplexer product with 1+1 redundancy backup of optical path protection,in modular design and flexible structure,independent functional modules but easy for combination,and able to derive a series of multi-service interfaces.Different interface modules can be selected based on various user requirements with available 4 modular slots and user requipments under different application environments can be catered to by adding or swapping interface modules.At the same time,users can start using escalation interface to adjust the scale of network interface based on their growth of services,so as to achieve a real-time follow-up of network to services.

Features:

Optical Path Backup:E3 or E6 optical path can be set,or switched,or mandatory switched,to meet requirements of high reliable network;

NM function:Available with NM Interface(RS485),to facilitate an easy achievement of network management;

Flexible Configuration:4\8\12\16E1 optical devices and multiple optional service interfaces are derivable from the system master board,to cater to different users and meet their requirements for customization;
