Detailed Product Description

DHODT-E4 Modular PDH Fiber Optical Multiplexer with 4 ports ethernet

DHODT-E4 is Modular Multi-Service Integrated Optical Multiplexer has been created with 8E1 capacity of transmission interfaces, of which 4E1 are available with the first interface and the rest 4 channels can be freely distributed to the other 3 interfaces (Interfaces II, III, and IV). In addition, another 4 Ethernet interfaces are provided to further meet individual demands of clients. This optical multiplexer is provided with multiple interface modules for voice, data, and image services for cities and industrial areas and its optional interfaces can support multi-service transmission tasks of MSEs, governmental departments, schools, or intelligent residential areas and other key clients or customer groups. Open standard interfaces are applied to guarantee a real-time interlinking with various equipments.

>>1+1APS: Automatic Protection Switching in which the transmission automatically switches to a STANDBY optical link in the event of a failure of the PRIMARY optical link, to ensure an uninterrupted business operation.
>>Easy to Configure:  The combination of system mainboard and various function modules can give out 4/5/6/7/8E1 optical multiplexers and multiple business matching interfaces, to meet requirements and customizing demands of individual users.
>>Multiple Function Modules:  Including user interface module (E1, Nx64K V.35, V.35, FXO/FXS, E/M, and RS232/RS485, etc.), order wire module, network administration module, RS232 data channel module, warning leading-out terminal module, and switching value channel module, etc.
>>Network Management:  Capable be monitored and managed through RS232 port in the front panel and can be managed by the software.
