Fabrication of a low-cost module for Gigabit Ethernet transceivers

In this paper, a novel way for the fabrication of opto-electronic transceiver modules is proposed. These modules are characterized by the use of MT-RJ connectors, low-cost fabrication tools, highly efficient opto-electronic components such as VCSELs and CMOS integrated detectors, and an easy fabrication scheme. The module is based on the direct alignment technique; this means that the fibre and the photo detector and laser diode are self and directly aligned with respect to each other, without the need for optical lenses. Cost are expected to be low, since the transceiver module can be fabricated using existing mass volume fabrication techniques
