ReceiverSection
ThereceiversectionincludestheReceiverOpticalSub-
Assembly (ROSA) and the amplification/quantization
circuitry. The ROSA, containing a PIN photodiode and
customtransimpedanceamplifier,islocatedattheoptical
interfaceandmateswiththeLCopticalconnector.The
ROSA output is fed to a custom IC that provides post-
amplificationandquantization.
ReceiverLossofSignal(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
compatiblestatussignaltothehost(pin8).Anadequate

throughtwentyI/Opins(SFPelectricalconnector)iden-
tified by function inTable 2.The board layout for this
interfaceisdepictedinFigure6.
The AFCT-57R5APZ high speed transmit and receive
interfaces require SFP MSA compliant signal lines on
thehostboard.Tosimplifyboardrequirements,biasing
resistorsandaccouplingcapacitorsareincorporatedinto
theSFPtransceivermodule(perSFF-8074i)andhenceare
notrequiredonthehostboard.TheTx_Disable,Tx_Fault,
and Rx_LOS require TTL lines on the host board (per
SFF-8074i)ifused.Ifanapplicationchoosesnottotake

Caution
There are no user serviceable parts nor maintenance
requirements for the AFCT-57R5APZ. All mechanical
adjustmentsaremadeatthefactorypriortoshipment.
Tampering with, modifying, misusing or improp-
erly handling the AFCT-57R5APZ will void the product
warranty. It may also result in improper operation and
possibly overstress the laser source. Performance deg-
