i'm told the model number of it is znid-ge-2424-na. i did some searching for the ubiquity ufiber loco and i'm only finding devices that are GPON, or Gigabit Passive Optical Network. you aren't going to be able to use that on utopia. GPON uses a different protocol on top of the physical later. utopia uses regular ethernet, at least according to the specs for that device. it'd be like both sides having a telephone line that connect each other but one side is speaking english and the other side speaking chinese. this isn't something that can be fixed by just changing a transceiver. it just converts an electrical signal to an optical one. the device actually knows the protocol. as an aside, GPON is what google fiber uses. it allows for a provider to connect multiple customers to a single transceiver in the providers equipment. saves a little money at the expense of sharing bandwidth between customer. the various fiber connectors are just that. physical connectors. you can usually find cables with different connectors on each end for different connections being used. for example, a SC to LC cable can be used to connect transceivers with the different connectors. now the apc vs upc vs pc vs normal thing is new to me. you wouldn't be able to use a cable with a SC APC connector with a transceiver that has a normal SC connector. i'm not entirely sure on whether upc, pc, or normal are interchangeable. hopefully i didn't just ruin your day. mike /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
