Description
The mechanical and electrical
interfaces of these converters to
the host system are identical for
all implementations of the
converter regardless of external
media type. A 20-pin connector is
used to connect the converter to
the host system. Surge currents
are eliminated by using pin

Converter specification Rev. 5.4.
The family provides a uniform
form factor for a wide variety of
standard connections to
transmission media. The
converters can be inserted or
removed from a host chassis

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 affect device reliability.

Transmitter Section
The transmitter section consists
of a 1300 nm MQW Fabry Perot
Laser in an optical subassembly
(OSA), which mates to the fiber
optic cable. The Laser OSA is
Receiver Section
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 photo
diode in the laser OSA. If a fault
occurs such that the dc bias
circuit cannot maintain the preset
conditions within 20ꢀ,
The receiver includes a PIN
photodiode mounted together
with a custom, silicon bipolar
transimpedance preamplifier IC,
in an OSA. The OSA interfaces to
a custom silicon bipolar circuit
driven by a custom, silicon bipolar that provides post-amplification
IC which converts differential
PECL logic signals (ECL
referenced to a +5 V supply) into
an analog drive current to the
laser.
and quantization. The post-
amplifier includes a Signal Detect
circuit that provides TTL
compatible logic-low output in
response to the detection of a
usable input optical signal.
TX_FAULT (Pin 10) will be
asserted (high).
The laser driver IC incorporates
temperature compensation and
feedback from the OSA to
Note: Under any single fault, the
laser optical output power will
remain within Class 1 eye safe
Eye Safety Design
The laser driver is designed to be
maintain constant output power
and extinction ratio over the
operating temperature range.
Class 1 eye safe (CDRH21 CFR(J), limits.
IEC 60825-1) under a single fault
condition.
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 affect device reliability.
