When installing a network, one of the first things users consider is whether to use fiber optic cable or copper cable. Although both copper cable and fiber optic cable can transmit an acceptable signal, fiber optic cable is the most desired choice with today’s growing bandwidth requirements over long distances. This article will share eight reasons why users should choose fiber optic cable over copper cable.

When installing a network, one of the first things users consider is whether to use fiber optic cable or
copper cable. Although both copper cable and fiber optic cable can transmit an acceptable signal, fiber
optic cable is the most desired choice with today’
s growing bandwidth requirements over long distances.
This article will share eight reasons why users should choose fiber optic cable over copper cable.
Fiber optic cable uses light pulses instead of electrical pulses to transmit data. Below are eight
reasons why users should choose fiber optic cable over the copper cable when installing their
network.
1. High Bandwidth Capability
Now more than ever, having the ability to transmit massive amounts of data over large distances
is a must-have in today’s environment. Fortunately, fiber optic cable has a higher bandwidth
capability than copper cable, making it the most popular option for users.
2. Low Attenuation and Long Transmission Distance

Attenuation is the loss of signal strength over distance, and fiber optic cable has lower attenuation
than copper cable. In addition, the transmission distance of fiber optic cable is much longer than
copper cable.
3. Light Weight and Small Size
Fiber optic cable is thinner and can be drawn to a smaller diameter than copper cable. Fiber optic
cable is smaller in size and lightweight than copper cable, offering a better fit for places where
space is a concern.
4. Electromagnetic Interference
Unlike copper cable, which conducts electricity, fiber optic cable does not have any metallic
conductors for transmission, so it is not prone to electromagnetic interference (EMI). Since it
doesn’t radiate EMI, tampering with the signal is almost impossible, making this cable a very
secure medium to transmit data.
5. Security
The copper cable transmits electricity, so it radiates signals. Unfortunately, it can be tapped, and
data can be visible anywhere along the cable. On the other hand, it’
s impossible to tap into a fiber
optic cable.
6. Passive Media
Fiber optic cable is considered a passive media since it is not connected to direct electricity or any
circuit protection concerns.
7. Universal Media
Fiber optic cable is called universal media as it transmits data, voice, and video through binary
code.

8. Long Lifespan
Fiber optic cable usually has a longer life cycle than copper cable.
Conclusion
Fiber optic cable provides high bandwidth, high reliability, high security, and a high-speed
internet connection that allows a lot of data to be transmitted over long distances. It has replaced
the copper cable in several aspects of networking. Sun Telecom specializes in providing one-stop
