TOTX194 is a fiber optic transmitting module for simplex digital signal transmission, data rate: DC to 10 Mb/s (NRZ code), transmission distance: Up to 1000 m, TTL interface, LED is driven by Differential circuit.
The TOTX194 is a fiber‑optic transmitting module for simplex digital signals. It supports data rates up to 10 Mb/s (NRZ code) and operates over transmission distances up to 1000 m. Key electrical parameters include a typical supply voltage of 5.0 V (range 4.75‑5.25 V) and input voltage limits of –0.5 V to Vcc + 0.5 V. Optical performance specifications list a peak emission wavelength of 800 nm and output power between –20 dBm and –14 dBm.
The document also details handling precautions, such as avoiding flux on the LED surfaces during soldering, using a soldering temperature of 260 °C for no more than three seconds, and protecting the module with a cap when not in use. Environmental limits are –40 °C to 85 °C for storage and operation, and the module is designed to resist vibration and shock when properly mounted.
