Figure 2 Functional Diagram
The receiver component converts the optical serial data into LVPECL compatible
electrical data (RD+ and RD–). The Loss Of Signal (LOS) shows whether an optical
signal is not present (lost).
The transmitter converts LVPECL compatible electrical serial data (TD+ and TD–) into
optical serial data. Data lines are differentially 100 Ω terminated.
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 laser fault to guarantee the laser Eye Safety.
The transceiver contains a supervisory circuit to control the power supply. This circuit
makes an internal reset signal whenever the supply voltage drops below the reset
threshold. It keeps the reset signal active for at least 140 milliseconds after the voltage
has risen above the reset threshold. During this time the laser is inactive.

Eye Safety
Eye Safety
This laser based single mode transceiver is a Class 1 product.
It complies with IEC 60825-1 and FDA 21 CFR 1040.10 and 1040.11.
To meet laser safety requirements the transceiver shall be operated within the Absolute
Maximum Ratings.
Attention: All adjustments have been made at the factory prior to shipment of the
devices. No maintenance or alteration to the device is required.
Tampering with or modifying the performance of the device will result
in voided product warranty.
Note: Failure to adhere to the above restrictions could result in a modification that is
considered an act of “manufacturing”, and will require, under law, recertification of
the modified product with the U.S. Food and Drug Administration (ref. 21 CFR
1040.10 (i)).
