Understanding Cable Technology-LightningMods™


Understanding the technologies supporting today’s cable telecommunications architecture is critical to making informed business decisions, thus maximizing an organization’s potential. In addition to learning about the core hybrid fiber-coaxial (HFC) and fiber to the x (FTTx) architecture, participants will learn about the technologies used to deliver high-speed data (HSD), video services, voice over IP (VoIP) telephony, and networking at the customer premises.  The course will then explore how to hold it all together with business and operations support systems (B/OSS).  In the conclusion learners will get a glimpse of cable’s future.
