how often is solid core wire actually used? it'd be theoretically better for long runs in plenum space where it won't move ever but not that much better surely?

because its for plenum cabling. thats the point

One cable I dislike is the one with the rubber seperater in the center.

i misremembered things i thought most plenum cable was stranded for some bizarre reason. likely because all the outdoor STP cables we use are stranded

I used to splice outside plant fiber for a living. it loving sucked.

Captain Foo posted:were you the guy that went up in the cherrypicker to get the splice boot to bring it into the truck and then fusion splice poo poo? infrastructure work is real critical but it sucks to do I did everything start to finish after it was pulled - dressed out the cabling properly on strand, prepped it into the splice boot, did all the splicing, and hung it up / strapped it out when I was done. If you want to see some of my work go drive around West Roxbury, Hyde Park, or Roslindale, I did a lot of work for your cable company there back in 2001. graph posted:i remember when a backhoe sliced the main fiber trunk at work the cable company brought out a little hut trailer and some dude just sat in there and spliced for like 40 hours oh yeah, it takes forever to do right although mass fusion / ribbon splicers help.

I've got a bunch of ribbon fiber at work we really can't do anything with, we're using it for pullcord

Captain Foo posted:an idiot waste of copper because at that point you really need to be using fiber iirc cat7 has each individual twisted pair shielded as well as the entire cable, and it's designed for 10GBe (which Cat6a can do anyway), so if you're doing superdense copper 10GBe installs i guess you use cat7? jfc just use fibers

you know what really sucks? having to rig up some bastardized poe setup on the unused pairs of a 100mbit run because some dumbass both put the switch + access point in a non-powered cabinet and said dumbass ordered non-poe gear to save money.
