the optical signal. The data “1” output optical power is com-
pared to the data “0” peak output optical power and expressed
in decibels. With the transmitter driven by a 25 MBd (12.5 MHz
square-wave) input signal, the average optical power is mea-
sured. The data “1” peak power is then calculated by adding
3 dB to the measured average optical power. The data “0” output
optical power is found by measuring the optical power when the
transmitter is driven by a logic “0” input. The extinction ratio is the
ratio of the optical power at the “1” level compared to the optical
power at the “0” level expressed in decibels.

shooting.
values for Spectral Width is derived from the assumption of a
Gaussian shaped spectrum which results in a 2.35 X RMS = FWHM
relationship. The optical rise and fall times are measured from
10% to 90% when the transmitter is driven by a 25 MBd (12.5
MHz square-wave) input signal. The ANSI T1E1.2 committee has
designated the possibility of defining an eye pattern mask for
the transmitter optical output as an item for further study. Avago
Technologies will incorporate this requirement into the specifica-
tions for these products if it is defined. The AFBR-5805 products

standard (ISO/IEC 9314-3 : 1990 and ANSI X3.166 - 1990) per the
description in ANSI T1E1.2 Revision 3. The interpretation of this fig-

lie along the appropriate Optical Rise/Fall Time curve.
