long wavelength LEDs. The actual degradation observed in Avago

optical signal. The data “0” output optical power is compared to
the data “1” peak output optical power and expressed as a
percentage. With the transmitter driven by a 25 MBd (12.5 MHz
square-wave) input signal, the average optical power is measured.
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 “0” level compared to the
optical power at the “1” level expressed as a percentage or in
decibels.

the trade-offs between center wavelength, spectral width, and
rise/fall times shown in Figure 11. This figure is derived from the
FDDI PMD standard (ISO/IEC 9314-3 : 1990 and ANSI X3.166 -
1990) per the description in ANSI T1E1.2 Revision 3. The
interpretation of this figure is that values of Center Wavelength
and Spectral Width must lie along the appropriate Optical Rise/
Fall Time curve.
