Figure 8. Recommended Panel Mounting
Power Supply Filtering and Ground Planes
It is important to exercise care in circuit board layout to
achieve optimum performance from these transceivers.
Figure 6 shows the power supply circuit which complies
with the small form factor multisource agreement. It is
further recommended that a continuous ground plane
be provided in the circuit board directly under the trans-
ceiver to provide a low inductance ground for signal
return current. This recommendation is in keeping with
good high frequency board layout practices.
Package footprint and front panel considerations
The Avago Technologies transceivers comply with the
circuit board “Common Transceiver Footprint” hole
pattern defined in the current multisource agreement
which defined the 2 x 10 package style. This drawing is
reproduced in Figure 7 with the addition of ANSI Y14.5M
compliant dimensioning to be used as a guide in the me-
chanical layout of your circuit board. Figure 8 shows the
front panel dimensions associated with such a layout.
Eye Safety Circuit
For an optical transmitter device to be eye-safe in the
event of a single fault failure, the transmit-ter must either
maintain eye-safe operation or be disabled.
The AFCT-5942xxxZ is intrinsically eye safe and does not
require shut down circuitry.
Signal Detect
The Signal Detect circuit provides a deasserted output
signal when the optical link is broken (or when the
remote transmitter is OFF). The Signal Detect thresh-
old is set to transition from a high to low state be-
tween the minimum receiver input optical power and
-35 dBm avg. input optical power indicating a definite
optical fault (e.g. unplugged connector for the receiver or
transmitter, broken fiber, or failed far-end transmitter or
data source). The Signal Detect does not detect receiver
data error or error-rate. Data errors can be determined by
signal processing offered by upstream PHY ICs.
