Fiber Optic Multiplexer pdh E1 V.35 ethernet LAN (DHDOT-E+)

Fiber optic multiplexer, fiber PDH, fiber converter, fiber optic equipment

The modular integrated optical transmission multiplexer is created with a 16*E1+10/100M auto-negotiating Ethernet capacity of transmission interfaces. The equipment also provides various interface modules for voice, data and video services in cities and industrial districts. Its optional interfaces support multiservice transmission of large customers and customer groups such as MSEs, governmental organizations, schools and intelligent residential areas. Open and standard interfaces are applied to guarantee prompt interlinking of various devices.

1)1+1 Optical Redundancy Backup: Protection of dual optical interface available to ensure that business will not be interrupted when one pair of optical fibres is confronted with failure. It supports hot swap of optical interface.
 2) Flexible Configuration: 4/8/12/16E1 optical multiplexers and multiservice interfaces are derivable from main system board and different functional modules, to meet different user requirements and customizations.
 3) Various Functional Modules: User interface modules (N*64K V.35, FV.35, FXO/FXS, E/M, RS232/RS485, and etc.), order wire module, network management module (RS232, and Ethernet Interface, etc.), and alarm output terminal module, etc. available.
