Two strand singlemode already costs far less per meter than ordinary cat6 utp nevermind cat6a or shielded stuff. Copper isn't cheap.

- teaearlgraycold 4y agoMaybe my future house should be wired for fiber...

- walrus01 4y agoone of the challenges there is that you can't do PoE over fiber, so for common house use with things like security cameras and 802.11ac/ax access points, you still want copper.
- DannyBee 4y agoit also has a better bend radius by far now. (cat6a is about 1 inch, g.657a3/b3 is <0.25 inches)
- sebazzz 4y agoNot easy to pull though typical European ductwork in the wall of a house.
- adql 4y agoAnd cat6 is ? Bend radius can be a problem with fiber but you can get bend-insensitive ones. The problem with fiber is really you need fusion splicer for termination and that's pretty pricy
- detaro 4y agoCouldn't you get away with mechanical splices? For short runs like this the extra losses shouldn't matter too much?
- adql 4y agoprobably ? No idea about details. I guess "just" terminating them would be fine if you just installed it once but at least looking at tutorials it does look like a PITA compared to CAT connectors
- DannyBee 4y agoA lot of tutorials are old. Mechanical splices have improved very quickly in the past 5 years. Talking with my friend who is an home automation installer, he says they now just use mechanical crimp splices and they don't take them longer than, say, prepping and terminating a coax cable. He says it's definitely shorter now than the average time they spend trying to untwist, straighten, and line up wires in a cat connector. They used to use connectors requiring polishes that took 30 minutes
- dale_glass 4y agoYou can do without splices at all, just fish the cable through the wall with connectors and all. The duplex LC connector can be disassembled, and with a bit of tape to keep things together you can get both fibers through much more easily. If you're lazy, you can just use a premade cable that's longer than you need. A slightly prettier solution is a keystone jack.
- walrus01 4y agomechanical splices should absolutely be avoided if at all possible, we live in the era of $900 made in china core alignment fusion splicers that are not terrible.
- DannyBee 4y agoYes, any level of bend-insensitive fiber has a better bend radius than cat6a. a3/b3 is much better. Cat6a min bend radius is about an inch. g.657a3/b3=~0.2 inch g.657a2/b2=~0.39 inch g.675a1/b1=~0.59 inch as for connectors, not anymore. They have simple ones that are just mechanical crimp. IE you cleave it, crimp it, and that's done. 0.15-0.25db loss, which is fine for a home run. also, LC connectors/etc are small enough that you can just fish them (they are less than half the size of a cat connector), or disassemble them and re-assemble. I have a fusion splicer, but i just fish completed cables with the connector covered. Also, these days you can get a reasonable fusion splicer on amazon for ~750 bucks that is 0.025db average loss. There are less and less reasons to run cat these days. QSFPTEK just emailed me this morning offering me multimode 100G-SR4 optics (100M, so same as ethernet) for 35 bucks a piece. They are regularly only 50 bucks a piece now anyway. 100G is obviously crazy for anyone's home need, but the point is the speed at which things like it are becoming cheaper is really high right now.
