Cable Prepares to Blend Docsis With EPON

Cable's lovefest with EPON is going to another level with the launch of a new CableLabs qualification program for EPON gear that uses Docsis-style provisioning.

The test plan represents the next step in the CableLabs Docsis Provision of EPON (DPoE) project introduced in the fall of 2010. The resulting specs (the 1.0 version was published in March 2011) will give cable a common way to graft their Docsis provisioning systems to the EPON world, something MSOs are keen to do as they continue to deploy EPON, primarily for business-class services.

And the vendors are already lining up. Nineteen suppliers, including Alcatel-Lucent (NYSE: ALU), Arris Group Inc. (Nasdaq: ARRS), Broadcom Corp. (Nasdaq: BRCM), Cisco Systems Inc. (Nasdaq: CSCO), Huawei Technologies Co. Ltd. and ZTE Corp. (Shenzhen: 000063; Hong Kong: 0763), participated in CableLabs's fourth DPoE interop in December.

The test program is an offshoot of the CableLabs Docsis program, but the R&D house has yet to say when it expects to conduct the first official DPoE test wave. CableLabs has another seven Docsis test waves scheduled for 2012. CableLabs also has not released what it will charge vendors for DPoE qualification testing, but, by way of example, testing a Docsis cable modem termination system (CMTS) runs $175,000.

Why this matters
With the cable industry picking EPON as its PON flavor of choice, DPoE will let MSOs and Docsis vendors preserve their legacy provisioning systems. The qualification program looks to ensure that DPoE-based gear is interoperable, giving MSOs the ability to buy from an array of vendors.

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
