Hello!
Interested in getting the larger community’s thought on this.
The primary question being does XGS-PON have a place in providing a
dedicated enterprise level service (at least sold as one) in the
marketplace? Delivered via a residential (per the data sheet
description) CPE, Nokia XS-010X-Q for a 1gb/1gb dedicated symmetrical
service.
Background, ive dealt with 30+ providers over the last 18 years,
primarily last mile based. Typically we seek out an
Enterprise/Dedicated service, with an SLA, typically delivered via
DWDM, CWDM, or AE, or equivalent. We have also had a site or two
delivered via a PON variant, typically with less of an SLA, typically
maybe half to quarter of the price of a dedicated service. Price &
SLA sets the expectation of the service, CPE provided, underlying
technology, etc.
Dealing with a large over-builder right now who has an “elite”
enterprise product (highest of 3 tiers) advertised as the following.
-100% dedicated bandwidth so you never have to compete for speed
-Mission Critical Reliability with 99.999% guaranteed uptime
-Financially backed SLA with the most stringent performance objectives
-Enterprise-level customer service and technical support
Now I understand with XGS, you can have various QOS in place (WRR/SP,
etc), but inherently there are still shared splits involved, that just
aren’t a thing in other truly dedicated technologies. Expectations
were set with the provider’s sales team around what was to be
delivered and how it was to be delivered that seemingly haven’t been
met by the product and service team.
That aside, from an SP perspective, is it capable to wrap enough
layers around service to be “dedicated” even when delivered via a
conflicting underlying technology? Or could that be considered
disingenuous for those that want to know and understand the
difference? Im hoping the service itself and support team make up for
the difference, but obviously a little concerned.
Regular GPON is already being used to deliver Enterprise services,
purely because it "passes by the office complex" on its way to the
residential neighborhood. Even when the Sales team are told not to use
GPON for Enterprise services, they end up doing so... first as a
"temporary, we have told the customer all the pitfalls" solution, which
eventually becomes permanent, and then it grows like wildfire.
You can expect that XG-PON will go the same way.
