The receiver component converts the optical serial data into PECL compatible electrical
data (RD and RDnot). The Signal Detect (SD, active high) shows whether optical data is
present
The transmitter converts electrical PECL compatible serial data (TD and TDnot) into
optical serial data.
This version contains an Input Signal Monitor (ISM), that switches the optical power off
if a continuously low level is applied at Data Input.
The transmitter contains a laser driver circuit that drives the modulation and bias current
of the laser diode. The currents are controlled by a power control circuit to guarantee
constant output power of the laser over temperature and aging.
The power control uses the output of the monitor PIN diode (mechanically built into the
laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the
operating limits.
Single fault condition is ensured by means of an integrated automatic shutdown circuit
that disables the laser when it detects transmitter failures. A reset is only possible by
turning the power off, and then on again.
The transceiver contains a supervisory circuit to control the power supply. This circuit
generates an internal reset signal whenever the supply voltage drops below the reset
threshold. It keeps the reset signal active for at least 15 milliseconds after the voltage
has risen above the reset threshold. During this time the laser is inactive.

Comments
Class 1 (>1000 V)
Discharges of ±15 kV with an air
discharge probe on the receptacle
cause no damage.
With a field strength of 10 V/m rms,
noise frequency ranges from
10 MHz to 1 GHz. No effect on
transceiver performance between
the specification limits.
Noise frequency range:
30 MHz to 6 GHz; Margins depend
on PCB layout and chassis design
