Drew suggested a break at 10km reach and
40km reach.
And while likely Single-Mode solutions that
support 300m will likely support 2km just as readily ... so in that case, it
will likely depending on the PMD adopted…. But I suspect that a distinct PMD
for >300m but <=2km probably is not warranted.

I agree datacenter for up to 100m. How
about 10GigE LR disctance (10km) or campus 2km discussed earlier?

John,
I
believe that the Data
Center distances should
be 100m and 300m.

[HSSG] Reach Objectives
|
|
All,
We
have had some conversation on the reflector regarding reach objectives.
Summarizing what has been discussed on the reflector I see the following
–
Reach Objectives
Long-Haul
--> 100+ km
Metro
--> 10+ km
Data
Center --> 50m & 300m
Data Center Reach Segregation
Intra-rack
Inter-rack
Horizontal
runs
Vertical
risers
Use
this data to identify a single low-cost solution that would address a couple of
the reach objectives
Other Areas
During
the course of the CFI there were individuals who wanted Backplane Applications
kept in for consideration, but I have not heard any further input in this area.
Are there still individuals who wish to propose Backplane as an
objective?
John
