Overview:

 

DHODT-E is modular integrated fiber optical multiplexer with 4 slots which can be installed different modules, like 4*E1, RS232, Ethernet, FXO/FXS..ect. 1+1 redundancy backup of optical path protection optional.

 

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, with independent functional modules while 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 requirements under different application environments can be catered to by adding or swapping interface modules. It is wildly used in voice and data application field
