Will Sonic be designing new greenfield systems (such as in Los Angeles region) using higher-capacity 50G-PON equipment?

An XPON trunk has a total capacity (each way) of approximately 10Gbps.
Provisioning multiple users on a given XPON trunk at the 10Gbps rate probably ensures no user will ever achieve 10Gbps.
There will always be some (perhaps a lot) of competing traffic on the trunk, leaving individual users to receive less (perhaps far less) than the 10Gbps throughput they expect to enjoy. (Especially important to customers moving BIG files all the time.)

Customers will see MUCH better service, if 50G-PON trunks (or similar) are installed.
Then multiple users on the same trunk can blast away at sustained 10Gbps speeds.

If Sonic adheres to a conservative approach regarding how many total customers are connected to any given PON trunk,
and if Sonic is careful to groom customers so that ONLY A FEW heavy-use customers are on any given 50G-PON trunk,
then the service will deliver on its 10Gig sales promise, word of mouth referrals will abound, and Sonic will put Frontier into bankruptcy (again). 50G-PON deployment is feasible in greenfield builds (like your upcoming deployments in the Los Angeles area). Frontier (et al) cannot easily deploy 50G in existing systems. This should give you a sustainable competitive advantage.

Due to the abundance of movie/tv industry creative talent living in the LA area, many folks are moving big raw-source video files around. (some are hundreds of Gigs). Transferring big files rapidly is a GREAT selling point for symmetric-speed FTTH. You will get great word-of-mouth sales, if the service actually delivers on the promise.

Over subscribing trunks has been common place in the cable industry. Frontier has (sort of) realized the importance of sustained throughput to compete against cable, and is moving some 5Gbps FTTH customers onto lightly-loaded trunks. (But we 5Gig customers are still only on 10Gbps XPON trunks.) If you are going to offer 10Gbps service to individual customers on a shared-use PON trunk, building with 50G-PON (or similar) high-capacity trunks will help Sonic deliver on its 10Gig promise. AND, help you to highlight the shortfall of Frontier's XPON speed and their over-subscription of trunks.

Hello!

I don't believe we will deploy any type of 50 Gig service down in LA anytime soon. Our current goal is to spread 10 gig to as many areas as possible. Even with multiple people on the same trunk, we are not seeing any type of speed degradation. A lot of the limitation comes from user devices and the router that is used. With very few routers offering 10 gig ports (I think Orbi has an 800$ router that supports it.) and most wifi connections not able to handle that speed (Its wifi) I do not believe putting 50 gig service trunks would improve the service any more than it already is. Let me know if you have any other questions.

Best Wishes!
