Useful Thoughts and Actions Taken

I just moved from Missouri to another state. What should I do with my old Missouri license plates?

To prevent unlawful use of your unexpired plates, you may destroy and recycle them where you are, or you may return them to any Missouri license office to be destroyed and recycled.
If you wish to mail them to our central office to be destroyed and recycled, please use the following address:


Missouri Department of Revenue
ATTN: License Plate Surrender
301 West High Street – Rm 370
Jefferson City MO 65105-0100


If you happen to receive a renewal notice for those plates, you may simply disregard the notice.
Unfortunately, Missouri statute does not authorize a refund of registration fees for unexpired plates

DSL Phone Line Extension

Research Notes

Given the graph below I surmise that the extra 500 feet to Loo's house will not affect the speed much.  

Conclusions

  • We can probably just use twisted pair inside network cable to extend DSL up to Loo's.
  • A back up plan would be to place the DSL modem at Claudio's and run the ethernet over fiber solution up to Loo's.

RF over Fiber

RF over fiber is where you modulate an RF signal onto the light beam and thus transmit it at a lower loss over a long distance.  It is an analog usage as opposed to a digital one as used in data transmission such as an ethernet extender. I have found some equipment for doing this but have not yet found anything that appears it will do the full Internet + Cable TV solution to extend the pole to internet modem solution that is cheap enough to use.

Conclusions

For now this is not a viable solution to the house in the forest long internet cable extension problem.  It will probably get there soon though.

Extending Ethernet Long Distances using Fiber Optic Media Converters

Research Links

 

The MC111CS and MC112CS are complimentary in that the Tx wavelength is the Rx wavelength of the other.  See excerpt below.

The MC112CS is a media converter designed to convert 100BASE-FX fiber to 100Base-TX copper media or vice versa. Adopting WDM technology, MC112CS takes only one fiber cable to transmit and receive data, which will save half cabling cost for you. Designed under IEEE 802.3u 10/100Base-TX and 100Base-FX standards, the MC112CS is designed for use with single-mode fiber cable utilizing the SC-Type connector. The MC112CS supports longwave (LX) laser specification at a full wire speed forwarding rate. It works at 1310nm on transferring data and at 1550nm on receiving data. So the other end device to cooperate with the MC112CS should work at 1550nm on transferring data and at 1310nm on receiving data. Another TP-LINK?s media converter MC111CS is just one of the examples to cooperate with MC112CS.

Note: (Fiber Attenuation /km in above table)
1. These values are per TIA/EIA and other industry specifications
2. These values are one example of the performance that can be obtained with a new fiber installation
