The TOTX179P is a fiber‑optic transmitting module designed for digital audio interfaces. It complies with the EIAJ CP‑1201 standard and uses a GaAs LED for optical output.
The document lists electrical, optical, and mechanical characteristics, recommended PCB layout, and detailed precautions for soldering, voltage limits, and environmental safety. It also includes handling and disposal instructions for the GaAs‑based LED.
| Data Rate | 12.8 Mb/s |
|---|---|
| Fiber Optic Power (max) | -15 dBm |
| Center Emission Wavelength | 650 nm |
| Supply Voltage (typical) | 4.75‑5.25 V |
| Current Consumption | 15‑20 mA |
| Storage Temperature | -40 °C to 70 °C |
| Operating Temperature | -20 °C to 70 °C |

| Withdrawal Force | 5.9‑39.2 N |
Use a supply voltage between 4.75 V and 5.25 V, and do not exceed the maximum rating of 7 V.
Solder at 260 °C or less for no more than ten seconds and keep flux away from the emitting and detecting surfaces.
The LED contains GaAs, which is toxic as dust or fumes; handle it carefully, avoid breaking it, and follow proper disposal regulations.
