Figure 3. Pinout drawing.
Each transmitter and receiver
package includes an internal shield
for the electrical subassembly to
ensure low EMI emissions and high
immunity to external EMI fields.
The outer housing, including the
ST* port, is molded of filled, non-
conductive plastic to provide
mechanical strength and electrical
isolation. For other port styles,
please contact your Avago
Technologies Sales Representative.
Each data-link module is attached
to a printed circuit board via the
16-pin DIP interface. Pins 8 and 9
provide mechanical strength for
these plastic-port devices and will
provide port-ground for forthcom-
ing metal-port modules.

Transmitter and Receiver Optical
Power Budget versus Link Length
The Optical Power Budget (OPB)
is the available optical power for a
fiber-optic link to accommodate
fiber cable losses plus losses due to
in-line connectors, splices, optical
switches, and to provide margin for
link aging and unplanned losses
due to cable plant reconfiguration
or repair.
Figure 4 illustrates the predicted
OPB associated with the trans-
mitter and receiver specified in this
data sheet at the Beginning of Life
(BOL). This curve represents the
attenuation and chromatic plus
modal dispersion losses associated
with 62.5/125 m and 50/125 m
fiber cables only. The area under
the curve represents the remaining
OPB at any link length, which is
available for overcoming non-fiber
cable related losses.
Avago LED technology has
produced 1300 nm LED devices
with lower aging characteristics
than normally associated with
these technologies in the industry.
The industry convention is 1.5 dB

Avago 1300 nm LEDs will
experience less than 1 dB of aging
over normal commercial
equipment mission-life periods.

Figure 4 was generated with an
Avago fiber-optic link model
containing the current industry
conventions for fiber cable
specifications and the draft ANSI
T1E1.2. These parameters are
reflected in the guaranteed
performance of the transmitter and
receiver specifications in this data
sheet. This same model has been
used extensively in the ANSI and
IEEE committees, including the
ANSI T1E1.2 committee, to
establish the optical performance
requirements for various fiber-
optic interface standards. The
cable parameters used come from
the ISO/IEC JTC1/SC 25/WG3
Generic Cabling for Customer
Premises per DIS 11801 document
and the EIA/TIA-568-A Commercial
Building Telecommunications
Cabling Standard per SP-2840.
