Title: BIDIRECTIONAL BOSA ASSEMBLY, OPTICAL MODULE AND PON SYSTEM
Abstract:
A bidirectional BOSA assembly, an optical module and a PON system. The bidirectional BOSA assembly comprises a base, an optical sending assembly, an optical receiving assembly, an optical fibre assembly and a WDM filter, wherein the optical sending assembly uses a first interface module to receive an electrical signal sent by a first peripheral circuit and uses an LD to convert the electrical signal received by the first interface module into an optical signal; the optical receiving assembly uses a PD to convert an optical signal in an optical network into an electrical signal, amplifies same by means of a TIA, and then sends same to a second peripheral circuit via a second interface module; the optical fibre assembly comprises a glass sleeve and an optical fibre, the optical fibre is arranged in the glass sleeve, a first end of the optical fibre is attached to an end face of the glass sleeve, and a second end of the optical fibre is connected to the optical network; and the WDM filter is arranged in the optical fibre assembly and is used for separating the optical signal transmitted by means of the LD in the optical fibre from the optical signal transmitted by means of the optical network in the optical fibre. The implementation of the embodiments of the present invention can reduce the costs of a BOSA.
