To calculate the distance that a DigitalMedia fiber transmission can be run, divide the bandwidth rating of the fiber by the
DigitalMedia bandwidth. NOTE: Maximum distance is 1000 ft.
Example:
Corning
®
infiniCor600
®
has the following bandwidth ratings: 500MHz*km @ 850nm and 500MHz*km @ 1300nm.
How far can you send DigitalMedia over that fiber? NOTE: 1,000 feet is the maximum distance.
850nm: 500MHz*km / 1200MHz = 416m (1365 ft)
1300nm: 500MHz*km / 150MHz = 3.3km (10,826 ft)
This fiber is able to drive DigitalMedia up to 416m (1365 ft). If you know the distance and need to determine which fiber
will work, you can also multiply the DigitalMedia bandwidth by the distance to find the minimum fiber bandwidth.
Example:
I need to send DigitalMedia over fiber 300m. What is the bandwidth requirement for my fiber cable?
850nm: 1200MHz * 300m = 360MHz*km
1300nm: 150MHz * 300m = 45MHz*km
Corning infiniCor600 supports 500MHz*km at both wavelengths, therefore it is an acceptable fiber type for this installation.
NOTE: 1,000 feet is the maximum distance.
Selecting the Jacket Configuration
When using fiber, it is recommended that you have at least two spare fibers for each location; a minimum of four strands in
your fiber jacket should be run to each endpoint. Ensure that your fiber cable has the correct ratings for your installation
(i.e. plenum, outdoor, UL, etc). Crestron recommends using a breakout type cable system for basic installations, because
the fibers can be directly terminated to the DigitalMedia equipment.
Minimum Fiber Optic Cable Bending Radius
Loaded: 20 x Diameter (0.313 in) = 6.26 in
Unloaded: 10 x Diameter (0.313 in) = 3.13 in
