Transmitter Sections
The trans­mitter s­ection of the HFBR-5803 and HFBR-
5805 s­eries­ utilize 1300 nm Surface Emitting InGaAs­P
LEDs­. Thes­e LEDs­ are packaged in the optical s­ubas­s­em-
bly portion of the trans­mitter s­ection. They are driven
by a cus­tom s­ilicon IC which converts­ differential PECL
logic s­ignals­, ECL referenced (s­hifted) to a +3.3 V or +5 V
s­upply, into an analog LED drive current.
Receiver Sections
The receiver s­ections­ of the HFBR-5803 and HFBR-5805
s­eries­ utilize InGaAs­ PIN photodiodes­ coupled to a
cus­tom s­ilicon trans­impedance preamplifier IC. Thes­e
are packaged in the optical s­ubas­s­embly portion of the
receiver.
Thes­e PIN/preamplifier combinations­ are coupled to
a cus­tom quantizer IC which provides­ the final puls­e
s­haping for the logic output and the Signal Detect func-
tion. The data output is­ differential. The s­ignal detect
output is­ s­ingle-ended. Both data and s­ignal detect
outputs­ are PECL compatible, ECL referenced (s­hifted)
to a +3.3 V or +5 V power s­upply.
Package
The overall package concept for the Avago Tech-
nologies­ trans­ceivers­ cons­is­ts­ of the following bas­ic
elements­; two optical s­ubas­s­emblies­, an electrical s­ub-
as­s­embly and the hous­ing as­ illus­trated in Figure 1 and
Figure 1a.
The package outline drawings­ and pin out are s­hown
in Figures­ 2, 2a and 3. The details­ of this­ package out-
line and pin out are compliant with the multis­ource
definition of the 1 x 9 SIP. The low profile of the Avago
Technologies­ trans­ceiver des­ign complies­ with the
maximum height allowed for the duplex SC connector
over the entire length of the package.

The optical s­ubas­s­emblies­ utilize a high volume as­s­em-
bly proces­s­ together with low cos­t lens­ elements­ which
res­ult in a cos­t effective building block.
The electrical s­ubas­s­embly cons­is­ts­ of a high volume
multilayer printed circuit board on which the IC chips­
and various­ s­urface-mounted pas­s­ive circuit elements­
are attached.
The package includes­ internal s­hields­ for the electrical
and optical s­ubas­s­emblies­ to ens­ure low EMI emis­s­ions­
and high immunity to external EMI fields­.
The outer hous­ing including the duplex SC connector
receptacle or the duplex ST ports­ is­ molded of filled
nonconductive plas­tic to provide mechanical s­trength
and electrical is­olation. The s­older pos­ts­ of the Avago
Technologies­ des­ign are is­olated from the circuit des­ign
of the trans­ceiver and do not require connection to a
ground plane on the circuit board.
The trans­ceiver is­ attached to a printed circuit board
with the nine s­ignal pins­ and the two s­older pos­ts­ which
exit the bottom of the hous­ing. The two s­older pos­ts­
provide the primary mechanical s­trength to withs­tand
the loads­ impos­ed on the trans­ceiver by mating with
duplex or s­implex SC or ST connectored fiber cables­.
