STANDARDS
although this is not an IEC Standard, so the question of timing does not exist. At the end of January last year, the basis of the Standard was discussed and with some of the items to be included in it. A rewrite will start once a series of questions have been answered. Included in these questions are the whole scope of the Standard, test equipment, limits, relevant products, relevant communication. A particular question was raised concerning Commission comments on frequency band for testing. It has been suggested that EMC measurements should be carried out at up to 5 times the current equipment’s highest frequency. This results in a top frequency of around 25GHz and gives a serious problem both in terms of test equipment able to cover the full spectrum and the cost to manufacturers. Drafts of part of the new Standard have been now created and the work continues. Following a successful new part 2, work on EN50083-8 will follow which covers EMC for systems. Working Group 3 This Group is currently working on part EN60728-103. This Standard incorporates the requirements for systems to support DOCSIS 4.0 and, with the adjustments, to make it compatible with ANSI SCTE 279-2022. A second draft of part 103 was issued as a CDV (Committee Draft for Voting) and currently we are expecting completion later this year.
Standards Update A report on the status of SCTE work with BSI.
This year like last was primarily work is on the standards covering Safety, EMC, DOCSIS and Optical.
SAFETY BS EN 60728-11:2023
Dave Hodges Vice President SCTE
Working Group 1 I look after safety. In 2023, Standard 60728-11 edition 5 became the new International Standard IEC EN 60728-11:2023 and a British Standard BS EN 60728-11:2023. Since then, we have started the process of resolving the EU Commission refusal of entry into the OJ (Official Journal of the EU). Entry into the OJ is important as it allows a presumption of conformity to the LVD (Low Voltage Directive) if the Standard is followed. Progress is now being made on the removal of the equipment part of the Standard which will allow a revised version to be introduced. This will allow the system only side to be issued although without the equipment LVD compliance. The equipment part of the Standard may then be worked on separately to provide the compliance. EMC EN50083-2:2012/PrA2:2019-06 Dr Basham looks after Working Group 2 EMC. We have a similar situation to part 11 with the EMC Standard BS EN 50083-2, and the EMC Directive,
Dave provides his annual insight as Chair of the SCTE’s Standards and Technical committee at BSI, CENELEC, IEC Standards and represents CENELEC TC209 in ETSI ERM17 Committees. He is also Chair of the BSI Technical Committee Cable Standards EPL100/04 and convenor of CENELEC TC209 / IEC TC100/TA05 working group 1 safety. I had hoped to report that we have had our third year of face-to-face meetings since the pandemic, but this was not to be. Unfortunately, the German hosts of CENELEC TC209 had too many other meetings to make room for us so we had a long week of online meetings which never seemed as if they would end. I have offered CENELEC TC209 and IEC TC 100 room at BSI for this year’s November meetings but there is a clash between IEC and CENELC that may prevent this. While remote meetings save travel and cost, they do so with the loss the personal interactions which take place, not only in the meetings, but also outside in the evenings and other odd times outside of the meeting times.
Optical Systems and Equipment
Working Group 5 look after optical systems. Over the last few years, this Working Group has been most productive as can be seen from the status table opposite. A further range of technical reports is being worked on which would cover guidelines for constructing FTTH systems using RF Broadcasting signals. The intention is to create versions which cover: - n Actual service systems and design considerations n Simple Measurement method & Maintenance n Cost reduction FTTH system using RF Broadcasting signals.
