    摘要: A laser diode module comprises a rectangular box-shaped metal casing having a bottom (B), an even number of guide pins (1-14) being led through the bottom (B) in a standardised DIL order. In addition to the laser diode itself (LD) the laser diode module further includes a metal base carrier (BC) on which the laser diode (LD), a photo diode (PD) and a support (S) for the glass fibre (F) are installed.
    The laser diode module comprises a guide pin (9) which is inserted in the bottom (B) by means of a feedthrough insulator for electrically connecting the laser diode module to an external transmission line (MT). In order to achieve a proper matching of the laser diode module and the charcteristic impedance of the external transmission line (MT), so that reflection phenomena are avoided and the laser diode module is made suitable for use in systems with considerably higher bit rates than 1 Gbit/s, the aforesaid guide pin (9) forms the inner guide of a coaxial transmission line situated inside the casing, of which transmission line the outer guide (CBL) is electrically conductively connected to the casing, whereas in the connecting line between the inner guide (9) and the laser diode (LD) a resistor (CS) is inserted having a value such that the sum of the resistances of this resistor (CS) and the laser diode (LD) is substantially equal to the characteristic impedance of the coaxial transmission line (9, CBL).

    摘要: A laser diode module comprises a rectangular, box-like metal casing having a bottom (B), whereas an even number of guide pins (1-14) are passed through the bottom (B) in a standardized DIL order and no less than one guide pin (5) is electroconductively connected to the bottom (B).
    In addition to the laser diode (LD) itself the module further includes a Peltier cooler (TEC) and a thermal metal base carrier (BC) coupled thereto, which base carrier accommodates the laser diode (LD), a photodiode (PD), a support (S) for the glass fibre (F) and a thermistor (TH).
    In order to render this laser diode module suitable for use in communication systems with bit rates that exceed by far 1 Gbit/s, the said guide pin (5) has inside the casing a portion in the form of a rod with a constant cross-section and with no less than one flat side face which over its entire surface has an electroconductive coupling with the relevant long sidewall (SW₁) of the casing, an electroconductive interconnecting strip being provided between the head face of the rod and the base carrier (BC)
