Note
Many factors contribute to the ability of a fiber optic data link to
transfer data efficiently. When the data rate across a fiber optic
datalink reaches gigabit rates, the factors that had very minor effect at
10Base and 100Base on the ability to recover the transmitted optical
data now carry a major influence. The designed/tuned optical
bandwidth is a key factor. Most single-mode fiber installed in the last 10
years is designed and optically tuned to operate in the 1310 nanometer
band. The IEEE Gigabit Standard for 1000Base-LX is setup to operate
in this optical bandwidth.
In order to extend gigabit optical datalink’s beyond 20 kilometers (12.4
miles), the 1550 nanometer band is being used. To recover a gigabit data
at this optical frequency band, the fiber has to be optimized or tuned for
1550 nanometers. The fiber optic’s industry has classified the best fiber
for this function as Non-Zero/Dispersion Shifted Fiber (NZ/DSF).
Contact your fiber optic installation contractor for all specifications of
your fiber.
