Kabel Gentian Optik Simplex VS Dupleks: Panduan Pembeli Terbaik

If you are thinking of buying kabel gentian optik, but are confused about which one to choose whether simplex or duplex. Well! Don’t panic. You can resemble simplex cable to one-way street where data only goes one way. On the other hand, a duplex cable resembles a two-way street where data can go back and forth. 

However, in this guide, we’ll discuss in detail what they are and their key differences to help you decide which one fits your needs and requirements. So, stay tuned with us!

Figure no 1 Understanding the differences between Simplex and Duplex fibre cables

1) Basic overview: Simplex vs duplex fibre optic cables

i) Simplex Fiber Optic Cable 

“A simplex fibre optic cable is a type of fibre cable specially designed for transmitting data on a singular path without expecting any replies.” 

A Simplex cable transmits data via a procession of a laser or LED light. The procedure begins when a laser or LED electricity sends light to a glass or fibre plastic strand. On the receiving side, there is a photodetector that turns the light into data. Moreover, a signal becomes reliable when there is no return path because there is no possibility of collision.

• Real-life example: 

A user named Girish Sundaram on Quora says that television signal is the best example of Simplex mode. That’s absolutely right, as we just see and listen to what is displayed on screens and we can’t respond or talk to characters, right?

ii) Duplex Fiber Optic Cable

“A duplex fibre optic cable allows for two-way communication simultaneously, just like a conversation because you can send and receive data at the same time. “

Now let’s see how a duplex works. Remember that, unlike Simplex which uses a single fibre core, duplex cables have 2 separate fibres, one for each direction of data transmission.

• Real-Life Example

Think about your experience using the internet. For instance, when you click a link, a request upload is sent, and a page begins loading (downloading) simultaneously. If however, we had to deal with the internet working on Simplex, you would need to first send a request, followed by waiting a while before the response decides to show up. How annoying! Isn’t it simpler with a duplex? 

2) Key Differences Between Simplex and Duplex Fiber Optic Cables

Now, you know the meaning of the words simplex and duplex, right? So let’s go through the fundamental differences which will help you identify it’s best suited to your requirements.

i) Direction of Data Flow: Simplex vs Duplex fibre cables

• Just like a one-way street, information can only flow in one direction through a simple fibre optic cable. This is the very reason simplex cables are best suited for such systems that do not require a response as they help in minimizing interference and process simplification.

• In contrast, a duplex fibre optic cable is similar to a two-lane highway where vehicles can go both ways, meaning data can be sent and received simultaneously. This is crucial for systems with instantaneous engagements such as the Internet or telephone calls.

 ii) Physical Structure: Simplex vs Duplex fibre cables

Secondly, bear in mind that the fibre optic cable’s cores influence fiber optic cable price, how well it functions, and how difficult it is to install. For example, 

• Simplex fibre optic cables are lighter and thinner because they have a single core. Furthermore, a single core does not need any other supporting equipment, making it economical in terms of installation and maintenance. 

• In contrast, duplex fibre optic cables are more complex and expensive and are also more difficult to install because it has two cores.

iii) Speed and Performance: Simplex vs Duplex fibre cables

• A simplex fibre cable offers unidirectional communication at ranges from 1 Gbps to 100 Gbps. Since the signal only travels in one direction, the need for a return signal could mean extra equipment, which could be problematic in terms of time.

• The ability to send and receive data simultaneously makes duplex fibre cables less prone to lagging while improving overall performance.

iv) Cost considerations: Simplex and Duplex fibre cables

As we know, most people prefer spending their money wisely, so let’s focus on the numbers. 

• Simplex fibre cables are less expensive than duplex cables because they include a single fibre strand, fewer connectors, and less complex equipment. So, if you need one-way communication and are on a budget, simplex is the way to go. 

• However, If your main concern is performance and you dont care about cost, then duplex fibre comes out on top.  It is expensive due to requiring more components.

v)Applications: Simplex vs. Duplex Fiber Optic Cables  

• Simplex Fiber Optic Cables: Usage scenarios

When considering simplex fibre, ask yourself, does my application need a feedback signal? If the answer is in the negative, then you will save money by using simplex fibre. Here is a look at some practical applications:  

• Fire Alarm Systems: Like in the previous section, you will put a simplex fibre into a fire alarm system. That is because it will trigger when it receives smoke signals and sends a signal to the control panel without waiting for any communication back.  

• RFID scanners: These are contactless key card scanners that have a one-way communication channel, so it is obvious that simple cables will be a great choice.  

• Traffic Control Systems: In the same vein, traffic lights get orders from a central source. The command is sent and there is absolutely no feedback required.  

• Broadcast networks (TV & Radio): There is no action from your side for receiving your preferred channels for TV and radio. You are communicated to and there is no demand to give feedback, simplex cables are useful here.  

• Industrial Monitoring Systems: Lastly, you have noticed that the sensors within industrial plants such as factories transmit performance information to a monitoring centre with no feedback communications, hence simplex cables are used.

• Duplex fibre optic cables: Usage scenarios

The duplex fibre optic cable is vital in systems that incorporate real-time feedback. For example, with;

• Internet Browsing: Each time you browse the internet, your device sends out requests while simultaneously receiving responses. You would require a duplex fibre for fast browsing because a one-way connection would not be sufficient. 

• Phone and VoIP Calls: A scenario where a phone call has an active restriction of one person speaking at any time is undoubtedly tedious, right? Phone calls become clearer with the use of duplex fibre because it allows for instant two-way communication. 

• Video Conferencing and Live Streaming: If you are part of a Zoom meeting or are watching a live stream, you understand how data flow ensures that there is a smooth transfer of information and interaction. Unlike the other types of fibre, duplex fibre provides seamless communication and visuals. 

• Stock Trading and Financial Transactions: Entering into the stock market also has a price every second which entails money is continuously being drained. In the world of finances, every second counts, and the information being sent and received cannot be delayed or else, it will mean losing money. This calls for the need for duplex fibre in all financial systems.

• Comparison Table:

	Simplex fibre optic cables	Duplex fibre optic cable
Data Direction	One-way	Two-way
Cores in Cable	1	2
Speed	1 Gbps to 100 Gbps	Faster
kos	Cheaper	More expensive
Usage	Alarms, RFID, clocks	Internet, phones, networks

3) Final Decision – Which One Should You Choose?

From all the above discussion, we have got the following key points for better understanding! You can choose Simplex if you only need one-way data transmission, need a less bulky one and your budget is also tight. However, You can go for Duplex if your system needs real-time two-way voice communication and cost is not a consideration only performance matters. Clear!
