| Electrically breaking a fiber connection? |
| (1/5) > >> |
| Pack34:
I'm looking to be able to terminate a fiber connection on-demand in order to simulate the fiber being disconnected and reconnected. I was going to try to use some fiber media converters but they do not seem to work when converting fiber-copper-fiber. Only copper-fiber-copper. |
| HB9EVI:
in theory it's working fiber-copper-fiber as well, but it depends... what light are you running over fiber? are you running simplex or fullduplex? in case you talk about a common FTTH access, it could be indeed tricky, since there are running two different wavelenght one in each direction at the same time; common mediaconverter normally work in a kind of CPE-mode; but you need then a converter like on provider side, which I don't know if they are available on the normal consumer market. |
| coppercone2:
do they have optical mechanical relays? maybe spin a prism or mirror? would be nice to have a bullet proof component for breaking fiber lines in remote areas where you don't wanna put weird IC's and PSU shit. |
| ejeffrey:
MEMS optical fiber switches are a thing. Is that what you are looking for? |
| TERRA Operative:
If you are talking standard LC or SC connectors, maybe a set of media converters, one to convert from fiber to copper and the other copper to fiber. Then on the copper interconnect between the two converters, set up a set of transistors or optocouplers or relay(s) or something to make and break the connection. It would allow you to use a manual switch or a microcontroller etc to simulate different faults as needed. |
