Hello wrightfrank11, and welcome to LQ.
No direct experience here. Plastic Optical Fibre (POF) is handy enough. I did a project with POF, which is flexible but lossy in 2013/2014, and it was all single rolls. But there are issues particularly with (nearly lossless) glass fibre:
- It's a bitch to join end to end.
- You can't bend it hardly at all.
For these reasons, or maybe to suit existing installation equipment, your glass fibre might be 1x 1000 metres instead of 2x500 metres, because that would save you 50% of joints in a long run. Glass fibre is mainly used over longer distances. POF needs repeaters after ~50 Metres. What are you using?
