http://www.htfuture.com/Products/DWDM-Transmission-System-173.html?DWDM Transmission SystemHTFuture Dense Wavelength Division Multiplexing (DWDM) are fabricated with thin-film interference coatings to achieve 100GHz or 200GHz narrow bandwidth channel filtering at ITU wavelength. It features small size, high reliability, high extensibility, simultaneous transmission of multi-wavelength. It can be used for wavelength add/drop in telecommunication network system.

HTFuture provides whole series of 1xN DWDM products that are tailored for specific applications.
Features
l Large capacity using optical fiber with single mode at present, the transmission rate of each channel can reach 10Gbit/s. And the total capacity can be 160Gbit/s.
l 1+1 backup system for heat redundancy of power supply
l Flexible and transparent access for various rates and services. It provides various rate and service accesses which can support the services of Ethernet, PDH, SDH, and CATV and etc.
l The interfaces of the plug and play customer service module cards can be both optical fiber port and RJ 45 Ethernet port. Customers can choose its type flexibly according to their requirement.
l Support single fiber, Bidi and dual fiber, Bidi transmission at the COM port of this system.
l Flexible network management configuration and management mode
l This system has high efficiency and eminence performance to protect customers benefit and investment.
