No but...
As I pointed out in my comments on the recent survey, feature/function/performance and system economics favor GPON, while the component cost advantage of EPON has disappeared. In fact, I hear that EPON ONUs are priced a bit higher than GPON ONUs (not that a few cents on a sub-$10 SKU matters that much). I'm also hearing about operators in Asia with EPON going with XGS-PON rather than 10GEPON, and some of them transitioning their networks over from EPON to GPON.

That said, EPON is not going away any time soon. In the US, the two largest MSOs, Comcast and Charter, plus many of the middle tier (Altice falls in the GPON camp, Cox has a little of both), have committed to EPON and (perhaps more important) DPOE. Their transition from HFC to FTTH will extend well into the middle of the decade.

I'll add that the latest generation of ONU electronics supports all flavors of PON, the optics are common between GPON and EPON, XGS-PON and 10GE-PON, and some of the ONU vendors have gone to common hardware. So really, the controversy is becoming moot.

Today’s access network architecture is under mounting pressure due to a continued surge in the number of connected devices, a proliferation of bandwidth-intensive customer applications and dramatic shifts in usage patterns related to the pandemic, such as work-from-home and e-learning.

Learn why now is the right time for cable operators to build greenfield networks or expand their existing networks with 10G PON, arming customers with high-speed symmetrical broadband. Gain a clear understanding of the drivers impacting the access network and the various approaches being considered to deliver higher speed services. Plus, find out the best practices that operators are employing as they leverage the latest in passive optical technology to future-proof their networks.

Topics to be covered include:

  • Node + 0 (Fiber Deep)
  • DOCSIS 3.1, DOCSIS 4.0 (FDX/ESD)
  • FTTP and 10G PON
  • Provisioning 10G PON within a DOCSIS B/OSS environment
