Cabling Material Selection  
   

Both coaxial cables and fiber-optic cables are used for HDTV-SDI cabling.

Coaxial cables are used for relatively short transmission distances, as shown in the table at right. For example, L-2.5CFB is better suited to cabling inside an equipment rack, and L-5CFB is a more appropriate choice for cabling between racks. Likewise, Canare's specially developed L-8CHD (high-foam coaxial cable) is ideal for cabling between rooms.

On the other hand, as can be seen from the fact that fiber-optic cables are now widely used in the communications field, they are better suited to long-distance transmission. Because the cost of fiber-optic transmission equipment can be expected to continue to fall, fiber optics is expected to make further inroads into the short-distance transmission field in the near future.
