DIN 18220: A MILESTONE FOR FIBER OPTIC EXPANSION
Noviembre 23, 2023
DIN 18220 COMES INTO FORCE
On 28.07.2023, "DIN 18220:2023-08. Trenching, milling and ploughing methods for laying empty conduit infrastructures and fiber optic cables for telecommunications networks" was adopted. The document was ceremoniously handed over at an event on the gigabit strategy of the Federal Ministry for Digital and Transport (BMDV). According to Section 126 of the German Telecommunications Act (TKG), it is to be applied uniformly by all parties involved as a recognized technical rule from the time of publication.
DIN 18220 is intended to contribute to the cost-effective acceleration and, above all, high-quality implementation of fiber optic expansion. It defines clear conditions for use and implementation and sets the legal framework for achieving a milestone in broadband and fiber optic expansion. DIN 18220 increases investment security for all parties involved, especially for telecommunications companies.
To date, there have been neither standardized framework conditions nor uniform principles for the application of the trenching method. Up to now, most municipalities have mainly chosen the open construction method as the laying method for fiber optic expansion, as the minimum overlap had to be at least 60 cm before the standard. Since 2012, the TKG has permitted the use of shallow laying (trenching, shallow laying methods), which also includes non-standardized methods such as trenching. However, the process has so far had difficulty establishing itself on the market. This is primarily due to legal uncertainties for all parties involved. These are inevitably associated with the lack of binding technical specifications, in the form of a binding standard, for the use of such alternative laying methods. The difficulty lay in particular in differences between road construction authorities, contractors and telecommunications companies regarding the specific execution and implementation. As a result, there were delays in the expansion of the fiber optic infrastructure.
THIS CHANGES WITH THE NEW DIN 18220
Up to now, most local authorities have mainly chosen the open construction method as the laying method for fiber optic expansion, as the minimum cover had to be at least 60 cm before the standard was introduced. DIN 18220 now regulates laying methods for reduced construction depths, including diamond trenching from LISSMAC (38 cm laying depth).
"With DIN 18220, fiber optic installation will not only be easier in the future, but also of higher quality, faster, more cost-effective and more resource-efficient. DIN 18220 creates the necessary legal certainty and investment security for all parties involved," said BMDV State Secretary Stefan Schnorr, describing the importance of the new standard.
WHAT DIN 18220 MEANS FOR LISSMAC
LISSMAC has been active in diamond trenching for around 10 years. Due to our experience in the field of joint cutting, we are a long-standing member of the VDMA (German Engineering Federation) and were involved in the creation of the standard as a member of the standardization committee. We are very pleased about the recognition of the alternative laying methods for fiber optic expansion, including LISSMAC diamond trenching, as the standard creates clarity for the construction industry, all municipalities, communities and telecommunications companies.
