    Analysis of the Tosarosa Device in Optical Modules

    In this paper, the optical design of 4-channel WDM Transmission Optical Subassemblies (TOSA)/ Receiver Optical Subassemblies (ROSA) is reported. The TOSA and ROSA are being developed for uncooled modules for CWDM applications and are compatible with the. First of all, the two most important parts of the optical transceiver are the optical transmitting assembly (TOSA) and the optical receiving assembly (ROSA). Among them, the optical transmitting assembly (TOSA) mainly plays the role of converting electrical signals into optical signals (E/O ). • Common Types of Optical Sub-Assemblies in Optical Modules The key components that perform electro-optical conversion in optical modules are called optical sub-assemblies (OSA). OSAs generally fall into three main categories: TOSA, ROSA, and BOSA. The. q Borrowing the idea of SF-VTRx from Csaba Soos (CERN, in the Versatile Link project), and with a custom coupler (called the Latch) for the TOSA and fiber, we developed the optical modules MTx and MTRx for ATLAS Liquid Argon Calorimeter's (LAr) trigger upgrade. MTx is a mid-board, dual-channel.
