A low cost PON transceiver using single TO-CAN type micro-BOSA

A novel low-cost small-form-factor (SFF) optical transceiver using a micro-compact bi-directional optical sub-assembly (micro-BOSA) for passive optical network (PON) application is proposed. In this micro-BOSA, optical transmitting and receiving functions are incorporated in a single TO-CAN package. The BOSA is compact and its pin assignment provides fine connection to printed circuit board and fit in transceiver housing. Bi-directional optical transmission at 1.25Gbit/s with the receiver minimum sensitivity of -28.2dBm is demonstrated for the fabricated transceiver with the proposed micro-BOSA
