Bi-Directional Optical Sub-Assembly When the transceiver is made small enough, the TOSA and ROSA can be integrated into one transceiver during the coupling process. the BOSA assembly consists of TOSA and ROSA (LD and PD-TIA), WDM filters (0 degree and 45 degree); isolators;. Optical modules are devices used to connect network devices, transmit and receive data between network devices, and can be used to convert optical and electrical signals. The optical module is a very important component in an optical communication system. This article will introduce you to the. Used in dual-fiber bidirectional or transmit-only optical modules, it converts electrical signals into optical signals and couples the light from the optical path into the optical fiber through internal optical components. Based on different laser chip designs, TOSAs are classified into VCSEL TOSA. Bi-Directional Optical Sub-Assembly (BOSA) refers to a single-fiber bidirectional optical device, which mainly consists of a transmitting laser, a receiving detector, an adapter, a filter, a base, an isolator and a die sleeve.
