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
driven by a custom, silicon bipolar IC which converts
differential PECL logic signals (ECL referenced to a +5
V supply) into an analog drive current to the laser.
The laser driver IC incorporates temperature
compensation and feedback from the OSA to maintain
constant output power and extinction ratio over the
operating temperature range.
Receiver Section
The receiver includes a PIN photodiode mounted
together with a custom, silicon bipolar transimpedance
preamplifier IC, in an OSA. The OSA interfaces to a
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.

custom silicon bipolar circuit that provides post-
amplification 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.
Eye Safety Design
The laser driver is designed to be Class 1 eye safe
(CDRH21 CFR(J), IEC 60825-1) under a single fault
condition.
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 ±20%, TX_FAULT (Pin 10) will be asserted (high).
Note: Under any single fault, the laser optical output
power will remain within Class 1 eye safe limits.
