OPTICAL TRANSCEIVER MODULE INTEGRATED WDM-COUPLER AND BI-DIRECTIONAL OPTICAL SUB-ASSEMBLY

摘要

PURPOSE: A wavelength dividing device and a bidirectional optical transceiving device integrated optical transceiver module are provided to decrease the number of components and to simplify an assembly process by integrating an existing WDM-coupler into a BOSA. CONSTITUTION: An input fiber(1) converts input light to collimated light through a dual core capillary(3) and a GRIN lens(4). A WDM filter(6) transfers transmitting light to an optical reception unit, an optical transmission unit and lets reflected light return to an optical output fiber through a GRIN lens. Collimated light output from the WDM filter is converted to a focused light after through an additional collimation lens(7) and reflected light by a dividing filter(8) enters into a photodiode(5).
