most common questions about the use of these parts.
Transceiver Optical Power Budget versus Link Length
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
transceiver specified in this data sheet at the Beginning
of Life (BOL). These curves represent the attenuation and
chromatic plus modal dispersion losses associated with
the 62.5/125 µm and 50/125 µm fiber cables only. T he area
under the curves represents the remaining OPB at any link
length, which is available for overcoming non-fiber cable
related losses.
Avago Technologies LED technology has produced 1300
nm LED devices with lower aging characteristics than nor-
mally associated with these technologies in the industry.
The industry convention is 1.5 dB aging for 1300 nm LEDs.
The Avago T echnologies 1300 nm LEDs will experience less
than 1 dB of aging over normal commercial equipment
mission life periods. Contact your Avago Technologies
sales representative for additional details.

Figure 4. Typical Optical Power Budget at BOL versus Fiber Optic Cable
Length.
Figure 4 was generated with a Avago Technologies fiber
optic link model containing the current industry conven-
tions for fiber cable specifications and the FDDI PMD
and LCF-PMD optical parameters. These parameters are
reflected in the guaranteed performance of the trans-
ceiver specifications in this data sheet. This same model
has been used extensively in the ANSI and IEEE commit-
tees, including the ANSI X3T9.5 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.
