 CATV Designing
Dear sir,

I would like to have at least a basic knowledge on catv networking, its design concepts, symbols
and other relative subjects concerning catv technology. Can your good office provide me articles
or documents that teach basic network designing of catv?

What does SFU and MDU stand for and what are they for?

Any reply will be greatly appreciated from you.

Thank you very much.

Dear Dennis,
It may be very helpful for you if you can browse to the Blonder Tongue Inc. Web page at
and download their catalogue in PDF file. It's packed with plenty of useful information, including basics, symbols etc. I'm sure that's what you need.

Besides, BICSI TDMM document contains very good section on CATV design. It's really a tutorial, so you may find it useful to read. The manual itself is really big, but it contains huge amount of information on almost any type of cabling, not only CATV. Please contact BICSI to acquire one.

MDU stands for Multi Dwelling Unit Building. When you calculate your cabling system for losses, you need to know, how many splitters you will get. That's why it's important to differentiate one-family residential house and condo for example.

I never used 'SFU' abbreviation before. Let me guess - Single Fiber Unit? Not sure, sorry.

With best regards,
Dmitri Abaimov, RCDD
