MSA.
Tx Fault
includes a loss of signal (LOS)
detection circuit which provides
an open collector logic high
output in the absence of a usable
input optical signal level.
The HFBR-5720L module
features a transmit fault control
signal output which when high
indicates a laser transmit fault
has occurred and when low
indicates normal laser operation.
A transmitter fault condition can
be caused by deviations from the
recommended module operating
conditions or by violation of eye
safety conditions. A fault is
cleared by cycling the Tx Disable
control input.
Transmitter Section
The transmitter section includes
the transmitter optical
Loss of Signal
The Loss of Signal (LOS) output
indicates that the optical input
signal to the receiver does not
meet the minimum detectable
level for Fibre Channel compliant
signals. When LOS is high it
indicates loss of signal. When
LOS is low it indicates normal
operation. The Loss of Signal
thresholds are set to indicate a
definite optical fault has occurred
(e.g., disconnected or broken
fiber connection to receiver,
failed transmitter).
subassembly (TOSA) and laser
driver circuitry. The TOSA,
containing an 850 nm VCSEL
(Vertical Cavity Surface Emitting
Laser) light source, is located at
the optical interface and mates
with the LC optical connector.
The TOSA is driven by a custom
silicon IC, which converts
differential logic signals into an
analog laser diode drive current.
This Tx driver circuit regulates
the optical power at a constant
level provided the data pattern is
valid 8B/10B balanced code.
Eye Safety Circuit
For an optical transmitter device
to be eye-safe in the event of a
single fault failure, the
transmitter will either maintain
normal eye-safe operation or be
disabled. In the event of an eye
safety fault, the VCSEL will be
disabled.
Functional Data I/O
Agilent’s HFBR-5720L fiber-optic
transceiver is designed to accept
industry standard differential
signals. In order to reduce the
number of passive components
required on the customer’s board,
Agilent has included the
functionality of the transmitter
bias resistors and coupling
capacitors within the fiber optic
module. The transceiver is
compatible with an “AC-coupled”
configuration and is internally
terminated. Figure 1 depicts the
functional diagram of the HFBR-
5720L.
Tx Disable
The HFBR-5720L accepts a
transmit disable control signal
input which shuts down the
transmitter. A high signal
implements this function while a
low signal allows normal laser
operation. In the event of a fault
(e.g., eye safety circuit activated),
cycling this control signal resets
the module as depicted in
Figure 6. The Tx Disable control
should be actuated upon
Receiver Section
The receiver section includes the
receiver optical subassembly
(ROSA) and amplification/
quantization circuitry. The ROSA,
containing a PIN photodiode and
custom transimpedance
preamplifier, is located at the
optical interface and mates with
the LC optical connector. The
ROSA is mated to a custom IC
that provides post-amplification
and quantization. This circuit also
