Mounting Studs
The mounting studs are provided for mechanical attach-

nonconductive plastic housing and are not tied to the
transceiver internal circuit and should be soldered into
plated-through holes on the printed circuit board.
This Signal Detect output can be used to drive a PECL

or Loss of Signal-bar.

Functional Description
Receiver Section
Design
Terminating the Outputs
The receiver section contains an InGaAs/InP photo
detector and a preamplifier within the receptacle, coupled
to a postamplifier/decision circuit on a separate circuit
board.
The PECL Data outputs of the receiver may be terminated
with the standard Thevenin-equivalent 50 ohm to V
2 V termination.
–
CC
Other standard PECL terminating techniques may be
used.
The postamplifier is ac coupled to the preamplifier as illus-
trated in Figure 1. The coupling capacitor is large enough
to pass the EFM test pattern at 125 MBd without signifi-
cant distortion or performance penalty.
The two outputs of the receiver should be terminated
with identical load circuits to avoid unnecessarily large
ac current in V . If the outputs are loaded identically the
CC
Figure 1 also shows a filter network which limits the band-
width of the preamp output signal. The filter is designed
to bandlimit the preamp output noise and thus improve
the receiver sensitivity.
ac current is largely nulled. The Signal Detect output of
the receiver is PECL logic and must be loaded if it is to be
used. The Signal Detect circuit is much slower than the
data path, so the ac noise generated by an asymmetrical
load is negligible. Power consumption may be reduced by
using a higher than normal load impedance for the Signal
Detect output. Transmission line effects are not generally
a problem as the switching rate is slow.
These components will also reduce the sensitivity of the
receiver as the signal bit rate is increased above 155 MBd.
Noise Immunity
The receiver includes internal circuit components to filter
power supply noise. Under some conditions of EMI and
power supply noise, external power supply filtering may
be necessary. If receiver sensitivity is found to be degraded
by power supply noise, the filter network illustrated in
Figure 2 may be used to improve performance. The values
of the filter components are general recommendations
and may be changed to suit a particular system environ-
ment. Shielded inductors are recommended.
The Signal Detect Circuit
The Signal Detect circuit works by sensing the peak
level of the received signal and comparing this level to a
reference.

PHOTODIODE
(rear facet monitor)
The transmitter section, Figure 3, uses a Multiple Quantum
Well laser as its optical source. The package of this laser is
designed to allow repeatable coupling into single mode
fiber. In addition, this package has been designed to be
compliant with IEC 825 Class 1 and CDRH Class I eye safety
requirements. The optical output is controlled by a custom
IC which detects the laser output via the monitor photo-
diode. This IC provides both dc and ac current drive to
the laser to ensure correct modulation, eye diagram and
extinction ratio over temperature, supply voltage and life.

The AFCT-5179xZ has two solderable mounting studs,
Figures 5 and 6. These studs are not electrically connected.
The transceiver is designed for common production
processes. It may be wave soldered and aqueous washed
providing the process plug is in place.

Each process plug can only be used once during process-
ing, although with subsequent use, it can be used as a
dust cover.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each
parameter in isolation, all other parameters having values within the recommended operating conditions. It should not
be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure
to the absolute maximum ratings for extended periods can adversely affect device reliability.
