Adtran is rapidly increasing its FTTP wins among US cable operators. Many of the vendor’s cable customers were willing to discuss their respective deployment strategies and challenges during Adtran’s 2015 combined Customer and Analyst Event earlier this month in Huntsville, Alabama.

Plan for the future; keep your customers and communities happy today

Many of Adtran’s FTTP cable operators are not the largest nor are they leading the communications standards for next-gen access. However, their insights and advice are relevant to cable operators regardless of size.

  • Fiber is inevitable to many cable operators. Adtran’s cable operator customers evaluated DOCSIS 3.1 but, as one operator stated, getting to symmetrical 1G services on hybrid fiber coax (HFC) cable is very complex and expensive when compared to FTTP.

  • Project costs and time are encountered in the outside plant while the complexities are in the inside plant. For example, project plans need to encompass availability of trained technicians.

  • Work cooperatively with local communities and officials, highlighting the economic development and real estate valuation advantages of high-bandwidth availability.

  • Keep residential customers happy but don’t over-promise. FTTP with bandwidth tiers provides competitive choices to residential customers, leading to lower churn rates. But they are still residential customers and unlikely to pay for strict service-level agreements (SLAs).

  • Demonstrate proof-of-performance while at the subscriber’s site.

  • Bandwidth demand will continue to increase. Build FTTP networks with 1x16 split ratios today or with the ability to easily move to 1x16 in the future.

  • Increased bandwidth usage in the access network requires upgrades to the metro network. Plan ahead and do metro upgrades before FTTP rollouts.

  • Involve your owners/investors early in the FTTP planning process, including the upgrade options and realistic ROI analysis.

We expect Adtran’s 2016 event to include even more cable operators with adoption of FTTP.
