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
optical interface and mates with the LC optical connec-
tor. 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 AFBR-703SDDZ 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 4. The host board layout for
this interface is depicted in Figure 7.
The AFBR-703SDDZ high speed transmit and receive
in terfaces require SFF-8431 compliant signal lines on
the host board. To simplify board requirements, biasing
resistors 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 operation.
Figure 2 depicts the recom mended interface circuit to
link the AFBR-703SDDZ to supporting physical layer ICs.
Timing for the dedicated SFP+ control signals imple-
mented in the transceiver are listed in Figure 6.

Caution
There are no user serviceable parts nor maintenance
requirements for the AFBR-703SDDZ. All mechanical
adjustments are made at the factory prior to shipment.
Tampering with, modifying, misusing or improperly
handling the AFBR-703SDDZ will void the product war-
ranty. It may also result in improper operation and pos-
sibly overstress the laser source. Performance degrada-
tion or device failure may result. Connection of the
AFBR-703SDDZ to a light source not compliant with IEEE
Std. 802.3ae Clause 52 and SFF-8341 specifications, op-
erating above maximum operating conditions or in a
manner inconsistent with it’s design and function may
result in exposure to hazardous light radiation and may
constitute an act of modifying or manufacturing a laser
product. 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
aqueous wash, IR reflow, or wave soldering processes.
