Receiver Section
The receiver section includes the Receiver Optical Sub-
Assembly (ROSA) and the amplification/quantization
circuitry. The ROSA, containing a PIN photodiode and
custom transimpedance amplifier, is located at the op-
tical interface and mates with the LC optical connector.
The ROSA output is fed to a custom IC that provides
post-amplification and quantization.
Receiver Loss of Signal (Rx_LOS)
The post-amp IC also includes transition detection cir-
cuitry which monitors the AC level of incoming optical
signals and provides a LVTTL/CMOS compatible status
signal to the host. A high status signal indicates loss of
modulated signal, indicating link failures such as broken
fiber or failed transmitter. Rx_LOS can also be monitored
via the two-wire serial interface (address A2h, byte 110,
bit 1).
Functional Data I/O
The AFCT-701SDDZ interfaces with the host circuit board
through the twenty contact SFP+ electrical connector.
See Table 2 for contact descriptions. The module edge
connector is shown in Figure 3.
The AFCT-701SDDZ high speed transmit and receive in-
terfaces require SFF-8431 compliant signal lines on the
host board. To simplify board requirements, biasing re-
sistors and AC coupling capacitors are incorpo rated into
the SFP+ transceiver module (per SFF-8431) and hence
are not required on the host board. The TX_DISABLE,
TX_FAULT and RX_LOS signals require LVTTL signals on
the host board (per SFF-8431) if used. If an application
does not take advantage of these func tions, care must
be taken to ground TX_DISABLE to enable normal op-
eration.
Figure 2 depicts the recom mended interface circuit to
link the AFCT-701SDDZ to supporting physical layer ICs.
Timing for the dedicated SFP+ control signals imple-
mented in the transceiver is shown in Figure 5.

Caution
There are no user serviceable parts nor maintenance
requirements for the AFCT-701SDDZ. All mechanical
adjustments are made at the factory prior to shipment.
Tampering with, modifying, misusing or improperly han-
dling the AFCT-701SDDZ will void the product warranty.
It may also result in improper operation and possibly
overstress the laser source. Performance degrada tion or
device failure may result. Connection of the AFCT-701
SDDZ to a light source not compliant with IEEE Std.
802.3ae Clause 52 and SFF-8341 specifications, operat-
ing above maximum operating conditions or in a man-
ner inconsistent with it’s design and function may result
in exposure to hazardous light radiation and may consti-
tute an act of modifying or manufacturing a laser prod-
uct. Persons performing such an act are required by law
to recertify and re-identify the laser product under the
provisions of U.S. 21 CFR (Subchapter J) and TUV.
Customer Manufacturing Processes
This module is pluggable and is not designed for aque-
ous wash, IR reflow, or wave soldering processes.
