Features
The modular integrated transmission optical multiplexer is created with optical path interoperability, flexible structure and modular design. Its function modules are independent of each other but easy for assembly, which enables it to derive a series of optical multiplexer products with multi-service interfaces. The equipment is furnished with four modular slots. According to the networking requirements of different users, various kinds of interface modules can be employed. Users can also add or replace interface modules to accommodate to the requirements of different application environments to protect their existing investment. Meantime, the equipment allows users to activate expandable interfaces to adjust the scale of network interfaces based on business growth, so as to help realize real-time follow up of network to business.
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. Supporting hot add/drop of optical interface, and fulfill switching without error code during hot add/drop.
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.
Various Functional Modules: User interface modules (N脳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.
A basic Modular Integrated Transmission System consists of a motherboard, four slots for optional pluggable interface boards, a power switch module and a user interface card. Order wire module, network management module, and alarm output module are also prepared for user selection. The system is provided in a structure of 19鈥 standard rack. It can be used not only as the desktop device independently but also installed inside the 19鈥 rack. The equipment height is 1.2U.
