TODX298 is a fiber optic transceiver module with analog output to monitor optical flux for duplex digital signal transmission.
This datasheet details the Toshiba TODX298 fiber optic transceiving module, designed for duplex digital signal transmission with analog output to monitor optical flux. It supports data rates up to 8 Mb/s and transmission distances up to 1000 meters using PCF fiber. The module includes an ATC circuit for stabilized output across varying optical power levels. Electrical and optical characteristics, typical performance graphs, and application circuits are provided. Precautions for use, including handling of LEDs containing GaAs, soldering procedures, and environmental considerations, are also outlined.
The module is intended for use in systems requiring optical signal transmission with noise resistance, and includes guidelines for mounting, shielding, and maintaining the optical output over time. It is suitable for applications requiring reliable, long-distance digital signal transmission with analog feedback.
