• Manufacturer Part Number: V23826-K305-C353
• Description: Multimode 850 nm 1.0625 Gbit/s Fibre Channel 1.3 Gigabit Ethernet 1x9 Transceiver
• Manufacturer: INFINEON [Infineon Technologies AG]

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 140 milliseconds after the voltage
has risen above the reset threshold. During this time the laser is inactive.
