Optical fiber network is gradually replacing copper network because
of its high speed, high density, high bandwidth and other
advantages. Compared with the traditional coaxial cable or twisted
pair cable, optical fiber is able to support further transmission
distance. But in fact, the transmission distance of optical fiber
is influenced by many factors. In the field of ultra high speed
optical communication, transmission distance has become an urgent
problem to be solved. With the development of optical fiber
network, the transmission distance of optical fiber has been
extended from several meters to hundreds of meters or even
thousands of meters. However, optical signals will become weak
during long distance transmission. Many optical devices are used to
solve the problem of limited transmission distance of optical
signals. Fiberall hereby summarize the main factors that limit
optical transmission distance.
1, Fiber type: Generally speaking, the maximum transmission
distance of optical signal in optical fiber will be affected by the
dispersion of optical fiber. Mode dispersion is the main factor
affecting the transmission distance of multimode fiber. Waveguide
dispersion is the main limiting factor in single-mode fibers. This
is because the core of single-mode fiber is much smaller than
multimode fiber. This is also the reason why single-mode fibers can
transmit farther distances than multimode fibers.
2, Laser of optical transceiver: The conversion quality of the
optical transceiver to the photoelectric signal is largely
determined by its internal light source. Light sources in optical
modules generally use LED (light emitting diode) or laser diode.
Their quality will directly affect the transmission distance of the
3, Transmission frequency: Different laser sources support
different frequencies. The frequency of optical signal will affect
the transmission distance of optical fiber transmission system.
Generally speaking, the higher the frequency is, the farther the
transmission distance is. Therefore, choosing the appropriate
frequency is very important for transmitting optical signals.
4, Bandwidth: is another important factor that can affect the
transmission distance. In most cases, the transmission distance is
inversely proportional to the increase of bandwidth.
5, Fiber splicing point: In optical network, the connection of
optical fiber is essential. Generally, there are two connection
ways of optical fiber: thermal splicing (fusion splicing) and cold
splicing, and optical fiber connector or fast connector. The
optical loss is easy to occur when the signal passes through these
fiber splice points, which will affect the transmission distance of
the optical signal.
Optical transmission distance is affected by many factors, such as
optical fiber type, light source, transmission frequency,
bandwidth, splicing point and optical fiber connector. When
deploying an optical fiber network, we should consider the above
factors and reduce the influence on the transmission distance.
