[802.3ae_Serial] Cable plant values?
Questions
-
1. Table 52-25
quotes 3.5 dB/km max attenuation at 850nm, whereas the spreadsheet uses 3.75.
10GFC also quotes 3.75 in its documentation. Which value is correct?
All 3
sources agree on 3.5 dB for 50 micron fiber.
2.
Table 52-24
shows channel insertion losses. Can someone explain where the values come from
for the 850 nm variants? Except for 2000 MHz-km, I get significantly
different values. The values in the table are not consistent with the model nor
with the budget tables for the PMDs.
Thanks,
Tom
