Tsuhan's PON BOSA is an integrated optical device with 1 transmitting channel and 1 receiving channel, which is mainly used in PON OLT and ONU transceiver modules with single-mode fiber transmission distance up to 20KM single-mode fiber. It is compliant with the Telcordia GR-468. ROSA (Receiver Optical Sub-Assembly) performs the opposite function by converting optical signals back into electrical signals. Understanding these components is essential for. An optical module consists of optoelectronic devices, functional circuits, and optical interfaces. OSAs generally fall into three main categories: TOSA, ROSA, and BOSA. consist typically of a single Laser Diode (LD), a Wavelength Division Multiplexer (WDM filter, and a single Photodiode (PD) An optical isolator can be used together with the laser diode to improve performance necessary to meet certain industry standards.
