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.

shooting.

shaped spectrum which results in a 2.35 X RMS = FWHM relation-

when the transmitter is driven by a 25 MBd (12.5 MHz square-wave)
input signal. The ANSI T1E1.2 committee has designated the pos-
sibility of defining an eye pattern mask for the transmitter optical
output as an item for further study. Avago Technologies will incor-
porate this requirement into the specifications for these products
if it is defined. The HFBR-5805 products typically comply with the
template requirements of CCITT (now ITU-T) G.95 Section 3.2.5,
Figure 2 for the STM-1 rate, excluding the optical receiver filter
normally associated with single mode fiber measurements which
is the likely source for the ANSI T1E1.2 committee to follow in this
matter.
The Beginning of Life (BOL) to the End of Life (EOL) optical pow-
er degradation is typically 1.5 dB per the industry convention
for long wavelength LEDs. The actual degradation observed in
Avago Technologies’ 1300 nm LED products is < 1 dB, as speci-
fied in this data sheet.

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.

time-width is set to simulate the effect of worst case optical
