CSE has developed numerous technical articles for the broadband industry beginning in the late 1980’s. Subject matter has generally dealt with telecommunications and RF, cable television (HFC) including the headend and plant design & operation, along with other subjects. Older ones that are considered still applicable are available for download. Many of the articles I've written over the years are not listed below due to space restrictions, so if you are looking for information on a specific subject and don't see it, please contact me at the email address shown at the bottom of all web pages as I may be able to help. 


Several years ago I also began authoring a quarterly column for the Broadband Library titled ‘Testing in Progress’. Recent and past subjects/issues from this column are shown below along with a link for viewing or download.


If you are viewing this from a mobile phone I recommend that you switch to a computer, as there simply isn't enough real estate on a phone screen to properly display this information.
