Someone who has a lot of experience with fiber optic cable told me that somehow the cable needs to be pushed through conduits rather than pulled like I would with a Cat 6. Is this true? If so, what is the best way to push the cable through?
It's less of an issue with multimode or large bundles of fibres but yes, for single mode fibres it can make a lot of sense to 'blow not suck', the way it's usually done is to attach the end/s of the fibres to some form of baffle that almost completely blocks the air on all sides of the conduit and then it's simply blown up the conduit. Think of it a bit like a blow-pipe.
Push Pull control cables are the most reliable means of transferring motion. They are available in various mounting configurations, travel or stroke length, overall length and temperature options.
3 Series Push-Pull (Rods 10-32 or M5-0.8)
4 Series Push-Pull (Rods 1/4-28 or M6-1.0)
6 Series Push-Pull (Rods 5/16-24 or M8-1.25)
8 Series Push-Pull (Rods 3/8-24 or M10-1.5)
If further assistance is required let me know.
