Transmode Systems has focused on supplying new "ultra-broadband" solutions for the companies – from one customer port to the other. Transmode has been a pioneer in the optical transmission systems for the new generation, redefining what the price and performance mean when we are talking about the area, metro and interface networks.
The optical transmission technology has been, and still is, one of the key factors in those changes seen in the telecommunications technology during the last years. The significant progression in the optical fibre production started a development process enabling the quick growth in the data traffic. The progress of the fibre amplifiers enabled the dramatic growth in the distances and in the number of the channels. The breakthrough of the Internet created fast a "black hole", which used up all the capacity focused on it. Due to this, the long-distance Dense Wavelength Division Multiplexing (DWDM) systems were introduced all over the world.
The most important present bandwidth users are for example Asymmetric Digital Subscriber Line (ADSL), Wireless Fidelity (Wi-Fi), Storage Area Network (SAN), 3G Mobile phone technology (UMTS) and IP calls. Their all have one common denominator: they all affect the data transmission demands on the metro areas or even more close the companies, homes and end users. This results in the growing need for the inexpensive, reliable, multi-purpose and easy-installable systems. The data transmission demands originating on the separate sides of the network bridge the gap between the end users and metro/frame network.
The traditional DWDM systems meet difficulties on the present, more challenging market, mainly due to their more expensive price structure, compared to the Coarse and Dense Wavelength Division Multiplexing (C/DWDM) systems with the changeable optical interfaces (so-called mini-GBIC, Gigabit Interface Converter).
The CWDM systems, pioneered by Transmode since 2000, are well suitable for the growing metro and local connection market. They include several features of the traditional DWDM systems, but are optimised for the metro area networks and are therefore less expensive.
In the System 1100 platform Transmode improves its CWDM solutions by adding the TDM aggregation feature into them by the new Universal Aggregator product family.
This makes an excellent extension alongside the already successful transponders, increases the utilisation rate of every CWDM channel and improves the cost-effectiveness at the same time.
System 1100 is a modular platform, which is adjustable in the number of the channels and in the operating range. The system can be enlarged into a CWDM system including 16 channels, by adding one channel or more at a time, without any breaks in the service or in the traffic.
When Transmode now introduces the changeable DWDM optics (SFP, Small Form-Factor Pluggable), it enables the system extension with 32 channels. It is also possible to obtain distances supported up to 180 km for the regional network applications, by adding an Erbium-Doped Fiber Amplifier (EDFA) into the equipment.
