Re: [8023-10GEPON] power budget ad hoc teleconference



Robert,
The standard temperature requirements are -40 to +65 C for Outdoor ONTs. You cannot assume Indoor only ONUs as several countries and service providers deploy outdoors for regulatory or operational reasons.

Regards,
Shane

When I consider the question of developing higher power DMLs at 1300nm, one
question that comes to mind is what are the temperature requirements for the
ONU?  Can we assume indoor ONU? If not, what temperature extremes are
appropriate?

All,

The next call(s) will occur on Tuesday April 10 at 7PM EST and Wednesday
April 11 at 9AM EST.

(Because of the US time change in March, I believe that 7PM EST Tuesday is
now 8AM Japan time on Wednesday.)

Toll-free in US	866-263-8899
Outside US 	816-249-6061
Conf. Code	7707985015

The following Orlando presentations, among others, may be relevant to the
discussions:

3av_0703_effenberger_1
3av_0703_takizawa_1
3av_0703_jiang_1
3av_0703_stefanov_2

In the call, I would like to address the following items. Please address
them on the Reflector prior to the call.

1. Much attention has been focused on the class B++ CH IL case.  The only
proposed power budgets for PX10 and PX20 are those in
3av_0703_effenberger_1, slides 6 and 7. Are Frank's numbers for PX10 and
PX20 met with components available today? Or would these also require
development as in the case of B++? Does anyone recommend any changes to
these? If not, should we plan to adopt them at the May meeting?

2. In analyzing the power budgets from effenberger and takizawa for class
B++, it seems clear (at least to me) that the following components must be
developed to meet the power budgets:

-- US 1300nm requires the development of a NEW DML, perhaps cooled, that can
output 3-4 dBm minimum at 1300nm, compared to a more typical 0 to 1 dBm at
present.
-- DS w/ APD requires a NEW EML with +3 dBm minimum output power, compared
to a -1 to 0 dBm typical minimum output power at present.
-- DS w/ PIN can be done with existing EML+EDFA; it MIGHT be done with
existing SOA with Psat(1dB)=10dBm, but might require development of an SOA
with higher Psat(1dB)=12 dBm.

All,

The next Power Budget Ad Hoc teleconference will occur on Tuesday April 10
at 7PM EST and Wednesday April 1 tentatively at 9AM EST.  I may have to
travel Wednesday and ask your flexibility if I need to push this time to
8:30AM or 9:30AM to accomodate.

The topics will be a review of power budgets presented at the March Plenary
by Frank Effenberger and Wenbin Jiang, as well as implications of the
presentation by Stefanov on SOA output power issues.

More details will follow.
