When it comes to choosing the amount and type of fiber to use in your system, protecting the fiber that carries telecommunications services is of primary importance. Between access fiber to the home (FTTH), and premise fiber to the CPE, there can be uncertainty about when to use which types of fiber cable. Today's most common options include:
- 900µ fiber
- 900µ jacketed fiber
- 250µ fiber within a strong polymer (2-4mm)
- Fiber cable within microduct
Bringing fiber into a home requires that you carefully consider several factors to choose the correct cable. At all points in the FTTH installation, the fiber must be flexible, tough, and lightweight, and for residences, aesthetically pleasing. Most fiber cables can accommodate one or two of these features but not all four. In addition, you must factor cost into the equation as prices vary - however, the installation and operational cost far outweigh the capital. The bottom line is that each FTTH installation is somewhat unique – whether the site is a multiple dwelling unit or a single residence, there are many variables that will determine which types of fiber are most appropriate in the different parts of the installation. In most cases, one size will not fit all.
