I am designing an Internet of Things system with fiber optics as its transmission medium (for its immunity to various kinds of interference and inability to carry a shock from a failed high voltage interface to the controller unit, school project, don't ask)
I am here asking whether I should socket the fiber optics module (possibly using a card edge connector), or I should just build the transceiver in? I do have space constraints.
If I socket the transceiver, which should be designed to be universal to all components that can accept one, are those signals and voltages adequate:
- +5V
- GND
- VDD (the system's IO voltage, some parts of the design use 5V logic, while some use 3.3V)
- TxD
- RxD
And what is the appropriate kind of card edge connector?
