Application Information
The Applications Engineering Group at Avago Tech-
nologies is available to assist you with technical under-
standing and design trade-offs associated with these
transceivers. You can contact them through your Avago
Technologies sales representative.
The following information is provided to answer some
of the most common questions about the use of the
parts.
Optical Power Budget and
Link Penalties
The worst-case Optical Power Budget (OPB) in dB for a
fiber-optic link is determined by the difference between
the minimum transmitter output optical power (dBm
avg) and the lowest receiver sensitivity (dBm avg). This
OPB provides the necessary optical signal range to
establish a working fiber-optic link. The OPB is allocated
for the fiber-optic cable length and the corresponding
link penalties. For proper link performance, all penalties
that affect the link performance must be accounted for
within the link optical power budget.

Recommended Circuit
Figures 6a and 6b show recommended dc and ac
coupled circuits for deploying the Avago Technologies
transceivers in +3.3 V systems.
Data Line Interconnections
Avago Technologies AFCT-5961TLZ/TGZ/ATLZ/ATGZ/
NLZ/NGZ fiber-optic transceivers are designed to couple
to +3.3 V PECL signals. The transmitter driver circuit
regulates the output optical power. The regulated light
output will maintain a constant output optical power
provided the data pattern is reasonably balanced in
duty cycle. If the data duty cycle has long, continu-
ous state times (low or high data duty cycle), then the
output optical power will gradually change its average
output optical power level to its preset value.
