Tips on 62.5/125 μm multimode fiber termination

Tips on 62.5/125 μm multimode fiber termination

Tips on 62.5/125 μm multimode fiber termination

(OP)
In hindsight, I would pull pre-terminated fiber and be done with it, but the cable is already run and I'm determined to terminate it.
I ran a 4-strand OFNP cable between two buildings (underground conduit). It's 62.5/125 μm multimode fiber, it says Superior Essex and Teragain on the exterior jacket. It looks practically identical to this:



I'm a novice at fiber termination, but have managed to successfully terminate multimode before--thankfully it's fairly forgiving. I am trying to find out how such cable (what I'm working with, specifically) is usually terminated. I've read several guides on terminating fiber, and most/all seem to be for individually-jacketed strands with their own bunch of kevlar/aramid fibers, instead of several strands and bunch of aramid fibers in a single jacket. I want a termination that's as tidy in appearance and sturdy in construction as possible, given the cable I'm dealing with. I'm not sure how the aramid fibers are intended to be used in terminating a cable like I have (divided between the fiber strands?) and in none of the guides I've referenced were aramid fibers left exposed after terminating is completed, but I don't know how to avoid this for several strands in a single jacket...? Also, connection boots all seem to be too large (internal diameter) to be of much value for terminating a single strand.

Thanks in advance for any tips/suggestions!

Or is the aramid fiber in this case only intended to be used for pulling the cable and to provide structural integrity (crush strength) to the cable as a whole -- should it be trimmed at the outer jacket, at the base of the exposed strands?

RE: Tips on 62.5/125 μm multimode fiber termination

The aramid fibers are only meant for pull strength to install the cable and to help hold the cable end in place after installation. They are not meant for structural integrity and are not used as a retainer (strain relief) at the fiber terminations. They do not get cut flush with the jacket but typically enough is retained to tie off the cable end to the shelf/cabinet to provide point of stability.

I believe the FIS (Fiber Instrument Sales) website has some video's to help to understand the termination process (mechanical or glue). If it's your first time I would suggest going the mechanical termination route since it is quite forgiving.
