Thanks Ed-

I guess I have been a mother hen over this - we are not installing the conduit/innerduct itself - but the customer is a friend and I'd like to see them do it right the first time.

They have a favorite all-purpose contractor doing the work and my guess is it could turn into a disaster unless I 'hen' it.

I don't think you are being a mother hen at all. I think that you are doing the right thing by coming here and soliciting feedback. That's what this forum is all about.

So, unlike fiber, there is no 50-pair cable that is rated for indoor/outdoor so it can be pulled all the way (and at some points exposed indoors, or just in an innerduct)? If there is I can't find it. Guess I'm stuck with that nasty icky pick for 600' of the 1100'.

I found the Nemco(?)50-pair entrance boxes if the 50-pair has to meet the 50' rule regardless. OSP in, IW out.

Fiber <$$$$$!!!!> wow - need to budget about $4500 for the cabling/cable parts (everything but network gear); or so through Lanshack.com. If someone knows a good wholesale fiber shop in the PNW or West Coast please let me know. Prefer to install pre-terminated 12-strand MM 62.5 with pulling eyes on both ends for all the flexibility possibly in pulling the fiber.

NC....we have a guy on here that does custom fiber cables...in NJ. Post in WTB.

If you don't want to deal with icky pic but once on each end, run it in metalic conduit from the entry to the terminal...then terminate. Make sure the tail splice from the terminal and the icky pic is enclosed properly.

I'll probably terminate the OSP at the building entrance on something like this https://www.circatel.com/pdf/100-66.pdf and then continue on from there. I know it isn't the best solution (read Ed's posts on another thread), but here in PDX lighting strikes are rare ... .

.......but how are you going to keep the icky pic from bleeding icky all over? IDC is okay for the output but what about the input?

You have never seen a mess until you see icky terminated on IDC.

CSC in Buena Park, CA will provide any configuration of pre-terminated fiber with pulling eye(s). You should confirm with your customer whether or not they want Laser-optimized multimode fiber (50/125) for faster future apps or plain old 62.5/125 multimode. CSC (714)670-7711 https://www.gocsc.com

Thanks BF.

I always want to inform the customer of their options. If we install the 10-gig MM fiber, will it add to my pain? I mean will current fiber modules, media converters (gig), connectors, 'my Amp Lightcrimp tester'/tools work with it?

I am surprised that the 10-gig 50 fiber isn't really that much more money, but if it opens a big can of worms in terms of compatibility ... probably a no.

The distance at this job is about 1150 feet. I can't get a clear answer on the max distance on the 10-gig fiber. Some say 500 meters, some say 300m or 984 ft. If it is 300 meters then it isn't going to work as a possible option.

Yes and Yes and Yes....and depending on the speed of the media converters ... fiber is at the speed of light ... how fast do you want to go?

1 gig or 10 gig or 100 gig....the fiber is just a media...yes, the faster, the cleaner the fiber has to be...but it still goes back to the media converters.

The distances you are talking about are so short it shouldn't make a big difference on speed.

Apparently it does. One Corning 50/125 fiber goes at maximum of 300 meters for 10-gig, and another goes to a maximum of 550 meter for 10-gig. So distance is a factor when you are trying to use MM fiber for 10-gig speeds.
