The cable broadband access network is complex extremely. Hybrid dietary fiber/coax (HFC), fiber-to-the-[feeder, constructing, curb, house, premises, tap], passive optical networks (PONs), digital movie, DOCSIS^®,  remote control PHY, quadrature amplitude modulation (QAM), orthogonal frequency division multiplexing (OFDM) – most of these technology have their very own technical info. And, for broadband wire technologists to work in their careers, they need plenty of details at their fingertips. 

Let’s state you’re out within the field executing leakage measurements upon CTA Channel 17 (indeed, they’re right now called CTA channels; the older EIA designation had been deprecated years back) and have to know the transmission degree at a dipole antenna’s terminals once the field power is 50 microvolts per meter (µV/m). The solution is in the manual. Can’t remember the by means of-reduction of a 12 dB directional coupler at 750 MHz? It’s in the guide. Desire to transform that optical receiver’s dBm input capacity to a value within milliwatts -2? The solution’s within the guideline. Forgot the center regularity of CTA Channel 116? It’s within the guide. Racking your brains on the weight in lbs of that container labeled in kilograms? The transformation aspect is in the guidebook. Taking an open-book check for your work, and forgot the free-space worth of the rate of lighting in meters per 2nd? That’s within the tutorial, too. 

And, for those at work back, no-one likes being caught within a plant design evaluation meeting being unsure of the attenuation-versus-frequency of varied sizes of coaxial wire and insertion lack of distribution passives for an instant spot verify of the brand new prints. The information is your buddy. I’m guessing it’s been a while because you calculated non-linear distortions within a cascade of energetic devices without the advantage of the spreadsheet. The formulas for that and solutions to much more come in the guide.

For several years, Cisco has recognized these needs by creating and keeping up-to-date a handy reference guide intended to be utilized as a quick-reference source for topics linked to broadband network technology.

This pocket-size reference guide is favored by installers, technicians, engineers, among others; we gave aside thousands and were becoming asked for more constantly. It’s hard to defeat the capability of a treasure-trove of extensive technical information in a single place. As a published spiral-bound book, customers would toss it within their trucks, go-luggage, and desks. The simple to utilize flipbook format was successful.

Given the existing environment, we we&rsquo thought;d make our newest version– the Cisco Broadband Data Book – Revision 21, in August of 2019 obtainable in an eGuide format released.

That link shall take one to close to the bottom of Cisco’s Cable Network Transformation website, where you’ll start to see the area “More Wire Network Resources.” Scroll to the click and directly on “Cisco Broadband Data Guide.” That will talk about a downloadable digital (PDF) edition of the Cisco Broadband Data Guide, Rev. 21 (217 pages!). Within the record, you can go through the preferred listing in the desk of contents to move right to that section.

I count myself on the list of fans of the gems but still have a small number of older specialized reference guides from the variety of manufacturers; some date to the past due 1960s and earlier &rsquo back;70s! That collection was previously bigger, but I donated section of it to The Cable Center within Denver, Colorado, which maintains a thorough assortment of cable industry pocket-size reference manuals in the Barco Edward and Library D. Breen Technical Archives.

I wish you discover Rev. 21 to become a reference. The accompanying photo displays a printed duplicate of Rev. 21 (still left) that was passed out at Cable-Tec Expo 2019, and my well-worn duplicate of Rev. 7, Scientific Atlanta’s CATV Data Guide from December 1990. For those who have a copy of a mature version than Rev actually. 7, fall me a note!
