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 connector.
The ROSA output is fed to a custom IC that provides post-
amplification and quantization.
Receiver Loss of Signal (Rx_LOS)
The post-amplification IC also includes transition
detection circuitry which monitors the ac level of
incoming optical signals and provides a TTL/CMOS
compatible status signal to the host (pin 8). An adequate
optical input results in a low Rx_LOS output while a high
Rx_LOS output indicates an unusable optical input. The
Rx_LOS thresholds are factory set so that a high output
indicates a definite optical fault has occurred. Rx_LOS
can also be monitored via the two-wire serial interface
(address A2h, byte 110, bit 1).
Functional Data I/O
The AFBR-57R5AEZ interfaces with the host circuit board
through twenty I/O pins (SFP electrical connector) iden-
tified by function in Table 2. The board layout for this
interface is depicted in Figure 6.
The AFBR-57R5AEZ high speed transmit and receive
interfaces require SFP MSA compliant signal lines on
the host board. To simplify board requirements, biasing
resistors and ac coupling capacitors are incorporated into
the SFP transceiver module (per SFF-8074i) and hence are
not required on the host board. The Tx_Disable, Tx_Fault,
and Rx_LOS lines require TTL lines on the host board (per
SFF-8074i) if used. If an application chooses not to take
advantage of the functionality of these pins, care must be
taken to ground Tx_Disable (for normal operation).
Figure 2 depicts the recommended interface circuit to
link the AFBR-57R5AEZ to supporting physical layer ICs.
Timing for MSA compliant control signals implemented
in the transceiver are listed in Figure 4.

Caution
There are no user serviceable parts nor maintenance
requirements for the AFBR-57R5AEZ. All mechanical
adjustments are made at the factory prior to shipment.
Tampering with, modifying, misusing or improp-
erly handling the AFBR-57R5AEZ will void the product
warranty. It may also result in improper operation
and possibly overstress the laser source. Performance
degradation or device failure may result. Connection of
the AFBR-57R5AEZ to a light source not compliant with
ANSI FC-PI or IEEE 802.3 specifications, operating above
maximum operating conditions or in a manner inconsis-
tent 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 re-certify
and re-identify the laser product under the provisions of
U.S. 21 CFR (Subchapter J) and TUV.
