[8023-10GEPON] [POWER BUDGET] resolving differences over PIN vs. APD
All,
As chair noted in his email of 6/12, please recall the discussion we had on
Monday evening in Geneva about pros and cons of PIN vs. APD in ONU.
Attached are the straw polls and points of argument.
I have identified three items in red to focus on initially.
<<APD vs PIN pro-n-con.pdf>>
1. An objection was raised to having an amplified EML at OLT due to
non-linear interactions between D/S and analog video overlay. David Piehler
supplied a response that will be posted separately to start a thread.
In two cases we had task force members stating directly contradictory
opinions:
2. one stated that PIN ONU leads to lowest fully subscribed cost, while
another stated that PIN ONU leads to highest fully subscribed cost.
3. one stated that high power EMLs (+2 to +3 dBm minimum output power) for
use with APD at ONU are commercially available today, while another stated
that such high power EMLs are not available today.
I would like to ask for volunteers who hold opinions on point #2 and point
#3 to volunteer to defend these those positions on the Reflector, with
back-up information.
Warmest Regards,
Robert
