Application Information
The Applications Engineering group in the Avago Tech-
nologies Fiber Optics Communication Division is avail-
able to assist you with the technical understanding 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 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, opti-
cal 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 series specified in this data sheet at the
Beginning of Life (BOL). These curves represent the at-
tenuation and chromatic plus modal dispersion losses
associated with the 62.5/125 µm and 50/125 µm fiber
cables only. The 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 normally associated with these technologies in
the industry. The industry convention is 1.5 dB aging for
1300 nm LEDs. The Avago Technologies 1300 nm LEDs
are specified to experience less than 1 dB of aging over
normal commerical equipment mission life periods.
Contact your Avago Technologies sales representative
for additional details.
Figure 4 was generated for the 1300 nm transceivers
with a Avago Technologies fiber optic link model con-
taining the current industry conventions for fiber cable
specifications and the draft ANSI T1E1.2. These optical
parameters are reflected in the guaranteed performance
of the transceiver 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 pa-
rameters 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.
