[10GBASE-CX4] Re: 10GBASE-CX4- Compliance Channel Insertion loss:
Please note that the term "e" in the compliance insertion loss channel below
is ( -.5 dB)
not (.5 dB) as originally given.
Insertion_Loss(f) < ((a*sqr(f))+(b*f)+(c*1/sqr(f)))+e (dB)
Where:
a = -2.25E-04
b = -6.08E-09
c = -2.08E+04
e = -.5 dB (Insertion Loss deviation)
Regards,
Chris
