• Owing to the growing demand and quality requirements of the optical transceivers, testing their performance is necessary and important. Fiber optics is a multi-parameter technology, so several factors must be considered while testing the optical transceivers. This post discusses different parameters and introduces testing methods of fiber optic transceivers. An optical transceiver features a transmitter and a receiver, so it is important to test this equipment for individual functionality. Different Techniques of Transmitter Testing and Receiver TestingLet us focus on different methods and parameters of transmitter and receiver testing. Testing TransmitterWhen it comes to transmitter testing, the following factors must be tested on a priority basis.  l Transmi...

Know why fiber optic cable is better than copper cable

Building a network with huge bandwidth and higher transmission speed has emerged as a key requirement in recent years. To accomplish this, several network cables have been used over the years. Traditionally, copper cables are widely used which are now being connected to fiber optic cables for better connectivity and geographical network expansion. In the case of new networks, especially in application where high-speed internet is a prerequisite, only fiber optic cables can be used entirely. Both cables offer unique advantages and specific beneficial features. Copper cables can be found in many places and they are an economical choice for network device connection. There are several advantages of fiber optic cables, which makes them a more enticing cable infrastructure solution than their copper counterpart. Would you like to know what makes them popular among other cabling installations or what are the benefits of fiber optic cables? This post aims to simplify the selection by discussing this cable technology in detail.
 

Why Choose Fiber Optic Cables Instead of Copper Cable

Both copper cables and fiber optic cables transmit data over the network but in very different ways. A copper cable carries electrical pulses along its metal strands, whereas fiber optic carries pulses of light along flexible glass threads. The following pointers will help you understand the difference between fiber optics and copper cabling and also the benefits of fiber optic cables in detail.

Huge Bandwidth: Copper cables are equipped with limited bandwidth, and thus preferred for a voice signal transmission. On the other hand, fiber optics offers more bandwidth than copper cable of the same diameter. This cable structure has a standardized performance of more than 10 Gbps. More bandwidth means more data transmission with greater reliability.

Long Distances: Both fiber and copper-based signaling suffer weakening of the waveform over distance. However, fiber optics transmit data over much longer distances. In fact, the differences are vast. Copper cables can carry signals to the typical length of 330-foot as per governing standards. Depending upon type and signaling of the cable, fiber optics can transmit up to well over 25 miles.

High Speed: Both cables can transmit data over the network, but undeniably fiber optics do this faster than copper cables. Fiber optics has a core that carries light to transmit data, allowing cables to carry signals at speeds around 31% slower than the speed of light. With fiber optic cables, there are fewer chances of signal degradation.

Highly Secured: Data transmission through fiber optics is always safe. Since the cable doesn’t transmit electricity, it can’t be tapped by an antenna, while copper-based cable requires an antenna to pick up the energy radiated from the cable, which will cause the entire system to fail. Besides this, fiber optic is made of glass and hence does not produce electromagnetic interference (EMI). So, it can’t catch fire easily.

Reliability: Fiber optic cable is resistant to weather changes and moisture, which can hamper otherwise hamper connectivity. As discussed earlier, fiber cable does not carry electricity, and hence seamless connectivity is possible.

Cost-effectiveness: The initial investment for fiber cables is much higher than copper cables. But, with the rise in production technology, the overall cost of fiber cables has steadily decreased. Also, it is cost-effective in the long run.

 

        With all the above-mentioned benefits, fiber cable has replaced the copper cable in several aspects of networking.
