I'm starting on a project that will involve digging a long (roughly 150-200 meter) trench from my house down to the road. The trench itself will be a considerable expense and so while the ground is open, I plan on laying additional conduit(s) containing any telecom links we may ever want, both for connecting to services currently available and ensuring we can use any services that might become available later. Currently only phone and cable are available at the road, but fiber-to-the-home has become available in other areas around us recently and I would hate to lose out by not being ready for it should it become available here.
Based on the distance, multimode fiber seems the best general option (vs CAT5/6 or singlemode fiber). POTS/DSL and cable are also available at the road currently.
To the specific questions:
- Is MMF really the correct choice, vs SM fiber or CAT6? Should I run both MM and SM?
- How many fiber lines is it reasonable to run for redundancy/backup? Should I include 2 or 3 lines from the outset?
- Is it safe/reasonable to run fiber, coaxial cable and POTS all in the same conduit over this distance?
- In principle, laying a second, empty, conduit with a strong comealong wire seems reasonable, but actually using it would certainly require a winch of some kind to pull it through over this distance, and I don't know if it is even practical. Any thoughts on this welcome.
- What additional cabling besides fiber, POTS and coax should I consider for future proofing this run?
I've done in-premises CAT5 installs before and played with fiber a bit at work but am not a network engineer so I suspect there are some unknown unknowns and would appreciate any comments or insight you may have. Thanks.
