Notes:
A sequence value of 1 indicates that the signal is in the rst group to engage during plugging of a module. A sequence value of 2 indicates that the
signal is the second and last group. The two guide pins integrated on the connector are connected to TGND. These two guide pins make contact
with circuit ground prior to Sequence 1 signals.
* This pin is tied high via 10 K pull-up resistor.
Note: All Avago Technologies GBIC modules comply with Module Denition 4 of the GBIC specication Rev 5.4

Transmitter Section
The transmitter section consists of an 850 nm VCSEL in
an optical subassembly (OSA), which mates to the ber
cable. The VCSEL OSA is driven by a custom, silicon bi-
polar IC which converts dierential logic signals into an
analog Laser Diode drive current.
Receiver Section
The receiver includes a GaAs PIN photodiode mounted
together with a custom, silicon bipolar transimpedance
preamplier IC, in an OSA. The OSA interfaces to a cus-
tom silicon bipolar circuit that provides post-amplica-
tion and quantization. The post-amplier includes a
Signal Detect circuit that provides TTL compatible logic-
low output in response to the detection of a usable input
optical signal.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each
parameter in isolation, all other parameters having values within the recommended operating conditions. It should not
be assumed that limiting values of more than one parameter can be applied to the product at the same time. Exposure
to the absolute maximum ratings for extended periods can adversely aect device reliability.

Eye Safety Design
The laser driver is designed to be Class 1 eye safe
(CDRH21 CFR(J), IEC 60825-1) under a single fault condi-
tion. To be eye safe, only one of two results can occur in
the event of a single fault. The transmitter must either
maintain normal eye safe operation or the transmitter
should be disabled.
There are three key elements to the safety circuitry: a
monitor diode, a window detector circuit, and direct
control of the laser bias. The window detection circuit
monitors the average optical power using the monitor
diode. If a fault occurs such that the dc regulation circuit
cannot maintain the preset bias conditions within ±20%,
the transmitter will automatically be disabled. Once this
has occurred, an electrical power reset will allow an at-
tempted turn-on of the transmitter. TX_FAULT can also
be cleared by cycling TX_DISABLE high for a time interval
>10 µs.
