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.
