CASE STUDY AROONA serves a Municipality’s networks ©Atypix The client’s issue The AROONA solution To keep up with the citizens’ ever-increasing needs of high When taking into account the location topology, deploying bandwidth, Frederikssund Municipality had to boost their new single-mode fibers (SMF) was a technically complex network’s capacity. The connection had delivered 100 Mb/s project including constructional work that could have been over a 1096 meter OM1 (62.5 µm / 125 µm) multimode fiber operationally and financially not feasable. The municipality (MMF) connection. Using 1310 nm boosters at each end, they chose the passive solution AROONA-STAR by Cailabs. With could get the connection up to 250 Mb/s, but above that, the this solution, the capacity of MMFs (OM1 - OM5) could speed fluctuates tremendously. potentially increase to 100Gb/s over long distances up to a few kilometers. The benefits of the solution • Drastically reduced project cost for upgrading fiber infrastructure • Installation done in a few hours • 10 Gb/s throughput instead of being limited at 250 Mb/s over their MMF links Increasing need for high bandwidth Frederikssund Kommune is a municipality on the shores of Andersen from Frederikssund Municipality. Roskilde Fjord in the northern part of the Danish island of “Using 1310 nm boosters at each end, we could get the Zealand.

Up until 2019, the connection had delivered 100 Mb/s Thomas Thorbjørnsen, over a 1096 meter OM1 (62.5 µm / 125 µm) multimode fiber Network Consultant (MMF) connection,” said Network Specialist Brian Christian Itectra, Denmark A complex and costly new fiber deployment The municipality thought that the only way to gain additional To increase the capacity of the existing 1096-meter-OM1 link, bandwidth, after increasing the capacity with 1310 nm boosters, AROONA boxes have been installed at each end of the fiber link was to add a single-mode fiber to the path. That would have between Skibby Library and the nearby Marbæk School. been very expensive when adding this to the cable duct. “After a design presentation from Itectra, the passive set up In close collaboration with Cailabs, Itectra designed and installation of the 2-port AROONA-STAR and Reach Extender presented the passive AROONA solution to Frederikssund products was done during the local school winter holidays,” said municipality. Brian Andersen. With this solution, the capacity of multimode fibers (OM1 - OM5) could potentially increase to 100 Gb/s over distances up to a few kilometers by eliminating modal dispersion in the multimode fiber. One 1096-meter-long optical OM1 link was upgraded Facilitation of the renovation project The AROONA-STAR solution allowed the Municipality to “Following this installation, the municipality – in collaboration overcome the 100 Mb/s limitation of their OM1 MMF link. with Itectra – is looking at installing AROONA in several other places in our network, where we have capacity problems on Based on the installation between Skibby and Marbæk - with existing multimode connections,” Brian Christian Andersen increased capacity for 1 Gb/s connection - Frederikssund continues, “It is extremely interesting to be the early bird Municipality expects further extensions in the long term, adopter of a technology like MPLC in the Nordic region.” including upgrading the same section to 10 Gb/s in the near future.
