Okay teach this old dog some new tricks

[Dickieboy]

I'm getting ready to do some design efforts in routing of Fiber Optic Cables from a cable tray to an outdoor I/O Cabinet. I have worked very little with fiber. The job spec only brings to the attention that conduit bends will be a minimum of 24" in routing the conduit sleeve from tray to cabinet. How many 90's can you stuff(or gentle tug) that fiber(6 and/or 12 core) thru and what distance? One more question ,do you make a rigid conduit connection to the I/O box or just stop it short and slack loop via a bushing and a gland fitting at the cabinet?

You'd probably be best served by getting the cable manufacturer's max pulling tension spec, then build your proposed run in Polywater's software and calculate the pulling tension. Compare to manufacturer's spec. Use a pulling tension meter on your tugger, preferably one that records and prints you a receipt.

I'm speaking of only the last 30 or 40 feet in a protective conduit sleeve.The tray application will be lay in, in most part,were is this doc available from?

I guess what may be more important to me initially is a set of typical installation details for fiber,,,,is anything like that available somewhere.

What part of the country are you in?
Lots of guys have a RCDD certification. Most specs will want to see that. You might want to look one up. PM me if you need help finding someone.

Since you'll be running this fiber both indoor and outdoor I'm guessing that you're going to use indoor/outdoor OFN cable. Strip off 24" of the jacket cut off all the fibers and form a loop with the strength members (Kevlar). Attach a snap swivel to keep the fiber from twisting as you pull. Tape it up. Pull only using the strength members and you will not damage the fiber as long as you don't pull across a sharp edge of the conduit. These cables pulled this way have a maximum of hundreds of pounds of pull force.
