Forum Post: Lighting control question

Our house construction is to the point of electrical and I have a porch that runs along with back of my house and a porch that runs along the front. Id like to have can lights on the front and back porch and I would prefer them to come on at dark and then dim to 25% around 9:00pm. Is this accomplished through an optical sensor in conjunction with a switch, or is there a programmable switch (that works with an app).. any ideas, Im not really sure what to search for. Thank You

Forum Post: How does information get from my computer to a transceiver in Fiber Optics?

I understand the basics of fiber optics. You have a transceiver (Tx) or WDM that converts electronic signals into light and sends it to another location via a fiber cable. At the other location its received (rx) by another transceiver where it is converted back into electronic signals. My question is as follows: How do these electronic signals go from my computer to the transceiver (transmitter)? and how do they go from the transceiver (receiver) back to the next computer? How are the electronic signals transported? Also, what equipment is necessary after the transceiver? Question #2: Is a switch IN a transceiver? or is it a different device all together? Is a WDM and a transceiver the same thing? Thanks in advance! PS: Any source documentation I can study up on will be highly appreciated! I'm trying to learn about internet connectivity and fiber optics :)
