V23818-N15-L616 Datasheet, PDF (6/20 Pages) Infineon Technologies AG – Small Form Factor Single Mode 1300 nm Multirate up to 2.5 Gbit/s Transceiver 2x10 Pinning with LC™ Connector, with Collar

V23818-N15-L6xx
Pin Configuration
BMon– / BMon+
The DC voltage measured across pins 17 and 18 is proportional to the laser bias current.
Use the equation:
I_bias = V_bias /10 Ω
Use this output to monitor laser performance and EOL conditions. A schematic and
typical behaviour are shown in Figure 5 and Figure 6. I_bias @ ambient 25°C < 60 mA.
Leave pins floating if function is not required.
