In July, an updated edition of series of standards EN 50173-x were published. Changes in these documents are very signifcant and they reflect those which were outlined in the 3rd edition of ISO/IEC-11801 published last autumn.
Below you can see the whole series of standards:
The most important changes in new editions:
1. Six new applications positioned within the performance of structured cabling, i.e. PoE type 3 & 4, 2,5GBase-T, 5GBase-T,
25GBase-T, 40GBase-T
2. Two new classes of channel performance i.e. Class I and Class II defined within the 2GHz band
3. The minimum performance of horizontal cabling subsystem defined as Class E/cat.6 replacing the previous class D/ cat. 5
4. Two new categories of optical fibers i.e. OM5 and OS1a
5. The removal of the optical channel performance of OF classes
Principal changes have been already discussed in a separate whitepaper that was publsihed this spring.
We invite all of you to read it, if you still did not manage to get to know this document.
