Basics of CWDM - Up to 18 different CWDM wavelength over one pair of fiber
Up to 18 CWDM wavelength over one pair of fiber
CWDM channel spacing 20 nm, 1270 nm to 1610 nm
Distances up to 120 km
Cost-effective WDM solution
Scalable by hybrid CWDM/DWDM - perfect solution for your investment
WDM-Module with up to 16 CWDM-Wavelengths.
Coarse Wavelength Division Multiplexing (CWDM) is a wavelength multiplexing technology for city and access networks. Transmission is realized using 18 channels with wavelengths between 1270 nm and 1610 nm. Due to the channel spacing of 20 nm cost-effective lasers can be used. The channel width itself is 13 nm. The remaining 7 nm is designed to secure the space to the next channel.
Optical Water peak
λ: 1271 nm - 1611 nm
Max. 18 channels can be used due to the waterpeaks
We have been using Pan Dacom Direkt products for our business connections on the Frankfurt airport site for years and are enthusiastic about the stability of the systems.
Klaus Schultz-Fademrecht (Senior Manager Networks, Fraport AG)
In addition to the optimal price / performance ratio of the SPEED-OTS 5000 system, we were impressed by the quick and easy commissioning and the good support.
Jochen Brünger (Leiter Informatik Produktion)
Our goal was to get an easy-to-use WDM system in order to connect our data center locations, which we can also scale in the future. In addition to the top advice and the good price-performance ratio, the very good References convinced us
The excellent price-performance ratio compared to the competition and the impressive references in the market were decisive for the purchase of the SPEED-OTS 500 system.
Ring-shaped, redundant connections from the production studios Freimann and Unterföhring to the Funkhaus location. In addition to company-wide telecom and IT-services such as 10 Gigabit Ethernet, STM-64 and 8G Fiber Channel, radio-specific ones also were supported.
The cooperation with Pan Dacom Direkt GmbH has been characterized by speed, reliability and stability for years. This, coupled with good cost efficiency and scalability, is the basis for the long-term partnership.
Gunnar Jäger (Geschäftsführer, Diebold Nixdorf Portavis GmbH)
Thanks to the professional advice and on-site inspection by Pan Dacom Direkt, we were once again able to save costs when networking our locations.
Together we have reached another milestone in the expansion of telecommunications. The fiber optic networking via deep-sea cables and the active transmissions in combination with the 24/7 monitoring enable us to quickly network our locations.
High-speed network FAIR Tera Net for research relies on the WDM system from Pan Dacom Direkt GmbH
The Matterhorn Gotthard Bahn uses WDM technology "Made in Germany"
Redundant structure of the existing connection of three switch nodes as well as increasing the data rate to 10GE or 40GE.
The system structure of the passive CWDM-modules, as well as the very good specifications of the WDM-filters, are decisive for us and enable a successive network expansion with the high-quality CWDM-optics.
Michael Philipp (Stellvertretender Direktor URZ)
Cooperation with the Pan Dacom Direkt team is always professional, uncomplicated and effective, starting with advice, planning, right through to technical implementation and support.
Frank Horst (Systemingenieur, ODN)
Through direct contact with the German-speaking Pan Dacom Direkt R&D department, we have managed to gradually replace a discontinued system with a system developed by Pan Dacom Direkt.
Fritz Röttenbacher (Head of Purchasing)
The SPEED-OTS 5000 convinced us with its individual and uninterruptible expandability, an optimal price-performance ratio and the reliable support from the German manufacturer.
