How To Check The Quality Of The Fiber Optic Adapter?

World development has picked up a greater pace with the Digital revolution. Every aspect of technology is advancing at a startling rate. And as we enter into the ‘Age of Data,’ three processes have seen exponential growth– data processing, transmission, and storage. Because everything we see today is based on the data, and if data is lost, there can be no past results and future innovations. 

Here’s the catch: Data transmission is paramount in today’s time. But how is data transmitted? From a technological view– fiber optics acts as the critical enabler of data transmission. It has set clear standards for data transmission speeds, bandwidth, and distances. For this purpose, fiber optic instruments are used, such as fiber optic adapters, fiber optic pigtails, fiber optic cables, etc.

What Is Fiber Optics, In General?

As a technology, fiber optics are used to transmit data through light pulses over fiber optic fibers. Fiber optics efficiently precede other technologies in data transmission over long distances. It is used widely by internet service providers, the telecom industry, and data centers. For these purposes, several types of equipment are used. 

In this blog, Telhua will share points to help individuals and businesses check the quality of fiber optic adapters.

Fiber Optic Adapter

Fiber Optic Adapters are special connectors designed to connect two ends of an optic cable within a large network. It allows establishing connections between many devices at once for communication purposes. It is a central part of a fiber optic connection. It can connect two end faces of an optical fiber. It further allows the coupling of transmitting and receiving optical fibers to the maximum extent possible.

Fiber optic adapters have a wide range of applications in fiber networking systems. Depending on your requirements, you can buy a fiber optic adapter with different interfaces. The most common type of fiber adapters available in the market is– LC adapters, SC adapters, FC adapters, etc. For example, LC adapters are best suited for harsh environmental conditions and mostly have industrial applications.

How To Buy A Quality Fiber Optic Adapter?

Considering the range of adapters, selecting a suitable adapter as per your requirements can be a little hard. However, the selection of an appropriate adapter is crucial for effective networking. When you buy a fiber optic adapter, consider these points:

Flame Retardant Level

The flammability rating of UL94 is considered the standard criteria for plastic material flammability performance. This criterion is used to evaluate the ability of any material to extinguish after it ignites. You can judge the flame retardant level on these grounds– burning speed, anti-drip ability, and burning time. Different test methods are employed for evaluating the flammability performance of an adapter. The retardant grades mainly vary from HB, V-2, V-1 to V-0. The level of flammability increases as we move from HB to V-0.

Insertion Loss

Simply put, insertion loss refers to the amount of light lost when the signal finally arrives at the receiving end of the optic link. The loss in normal cases has to be below 0.2 dB for effective transmission. If the loss is too high, it affects the output of the optical transmission in a fiber optic network system.

Durability And Repeatability

When using adapters, an individual has to plug and unplug the fiber optic adapters frequently. So, to ensure the smooth transmission of data, the durability and repeatability quotient of optic adapters has to be high. In other words, an adapter should deliver optimum performance even after getting plugged and unplugged 500 times. The insertion loss should remain the same as before and does not change while using.

Working Temperature

Although, fiber optic adapters are widely used in industries and harsh environments. Still, an adapter operates in the average temperature range of -40 to 75 degrees Celsius.

The Material Is Aligned With The Sleeve

Alignment sleeves are a key component in adapters. Mostly ceramic or metal materials are used as alignment sleeves; however, the effect of ceramic fiber optic adapters is comparatively better than their metal counterpart. Because ceramic Material is hard and does not get deformed easily. 

These points will help you differentiate a high-quality and stable fiber optics adapter from an unreliable one. You must also consider points such as compliance standards and strength as these can potentially impact the performance.
