What is Fiber Optic Pigtails

A fiber pigtail is typically a fiber optic cable with one end factory pre-terminated fiber connector and the other exposed fiber. It is usually suitable for field termination using a mechanical or fusion splicer. Compared with quick termination or epoxy and polish connections placed on the field site, the pre-terminated connectors provide time-saving, superior performance, and reliability.

Benefits of Fiber Optic Pigtails

The Structure Adopts Non Embedded Optical Fiber Structure
There is no embedded optical fiber and matching paste inside the device. After the optical fiber is installed and clamped, the end face of the optical fiber can be checked with a magnifying glass,It can avoid excessive loss of optical fiber connection. Axial belt positioning mechanism, during the clamping process, the optical fiber will not move forward axially.

The Reliability Of Optical Fiber Clamping Is Very Good
The optical fiber clamping elements are made of elastic metal materials, and there is no aging problem of plastic elements; Temperature change has little effect on the clamping force of optical fiber; In addition, there is a locking mechanism inside the device, which has very good anti vibration and anti drop performance.

Good Connection Stability
There is axial adhesion force at the optical fiber butt joint. When the optical fiber butt joint, the end gap between the two optical fibers is almost zero, so the connection loss is often less than or equal to 0.3dB, or even less than or equal to 0.1dB; Since no optical fiber matching paste is used, There are problems of loss, pollution and aging of optical fiber matching paste; In addition, the reliability of optical fiber clamping is very good, which also determines the stability of connection.

Low Insertion Loss
Because the device is designed according to the structure of non embedded optical fiber, and there is only one optical fiber pair contact, the connection loss is generally less than that of the existing optical fiber quick connector.The axial tensile force borne by the device directly acts on the shell of the device. The ceramic pin of the connector is not subject to tensile force and does not affect the optical fiber docking effect, so it has no effect on the connection loss.

Application of Fiber Optic Pigtails

Elecommunications Industry
In the telecommunications industry, fiber optic pigtails play a vital role in transmitting large amounts of data over long distances with minimal signal loss. They are usually used in the construction of telecommunications networks to provide stable, high-speed connections for voice, data and video communications. Data centers rely heavily on fiber optic pigtails to ensure efficient and secure data transmission within their networks. The high bandwidth and low latency of fiber optic cables make them ideal for handling the large amounts of data processed in data centers, ensuring fast and reliable communication between servers and storage devices.

Medical Field
In the medical field, fiber pigtails are used in various medical instruments and equipment, such as endoscopes and surgical lasers. The high flexibility and durability of fiber optic cables make them suitable for medical applications, allowing precise and reliable transmission of data and images during medical procedures.

Cable Television (catv) Industry
In the cable television (CATV) industry, fiber optic pigtails are used to carry high-definition video and audio signals to subscribers. Fiber optic cable's superior signal quality and reliability make it the first choice for transmitting television broadcasts, ensuring viewers receive clear, uninterrupted content. Fiber-to-the-home (FTTH) installations, in which fiber pigtails are used to connect homes to high-speed Internet services, have become increasingly popular in recent years. By utilizing fiber optic cables, service providers can provide their customers with faster internet speeds and more reliable connections, thereby enhancing the overall internet experience of their users.

Industry And Military
Industrial and military applications also benefit from the use of fiber optic pigtails because they can provide safe and reliable communications in harsh environments. Whether used in industrial control systems or military communications networks, fiber optic cables provide a powerful and efficient solution for transmitting data over long distances.

Types of Fiber Optic Pigtails

LC Fiber Pigtail
LC connectors are compact form factor fiber connectors for high-density connections. They are a 50% smaller version of the older SC fiber connector and have a square plastic enclosure with a 1.25mm ceramic ferrule. The LC fiber pigtails are pre-assembled with an LC connector. It is one of the most common types.

SC Fiber Pigtail
SC, which stands for Subscriber Connector, has also been called Square Connector or Standard Connector. The SC connector has a 2.5mm pre-radiused zirconia or stainless alloy ferrule. The SC fiber pigtails are pre-assembled pigtails with an SC connector. Because of the low cost, longevity, and ease of installation, SC pigtail is commonly used in both P2P and PON applications.

FC Fiber Pigtail
FC fiber pigtails benefit from the metallic body of FC optical connectors, which have a screw-type structure and high-accuracy ceramic ferrules. FC fiber pigtails and related items are widely used in various applications.

ST Fiber Pigtail
ST fiber pigtail is similar to the FC pigtail, but instead of threads, the ST connector has a locking mechanism different from FC connectors. It has a ferrule with an extended 2.5mm diameter composed of ceramic (zirconia), stainless alloy, or plastic. As a result, ST pigtails are commonly used in telecom, industry, medical, and sensor applications.

Fiber Pigtail vs. Fiber Patch Cord: What Is the Difference?

First, The Most Critical Difference Is The Fiber Connector
Fiber optic pigtails have only one terminated connector on one side but bare fibers on another side. In contrast, the patch cords have two or more pre-terminated connectors on each side and have no bare fibers.

Second, The Difference Is The Fiber Cable Types
Fiber optic pigtails typically use an unjacketed cable like a 90μm diameter cable. However, the patch cords usually use jacketed fiber cables, such as 2.0mm or 3.0mm fiber.

Third, The Different Applications
Fiber optic pigtails are mainly for fast fusion splicing applications, while patch cords are for connectivity between optical transceivers, patch panels, and backbone networks.

Components of Fiber Optic Pigtails

Optical Connector

This is the pre-installed end of the fiber pigtail. It's the component that gets plugged into the optical device or panel. Different types of connectors exist, like SC, LC, FC, ST, and E2000, each serving other purposes and environments.

Core and Cladding

The body is the thin glass center of the fiber where the light propagates. Surrounding the body is another layer of glass known as the cladding. Their combined structure enables total internal reflection, allowing light to travel down the fiber.

Buffer Coating

This is a plastic coating that protects the fiber from damage and moisture. In fiber pigtails, this coating is usually tight-buffered, meaning it's directly in contact with the cladding.

Splice

This refers to the junction where the exposed end of the fiber pigtail is joined to another fiber. Fusion splicing, which uses heat to fuse the threads, is the most common method as it provides a high-quality, reliable splice.

Transmission Modes

Fiber pigtails can be single-mode or multimode. Single-mode fibers transmit one signal per fiber and are used for long-distance transmission. In contrast, multimode fibers transmit multiple light rays or modes simultaneously and are used for short distances.

How to Choose Fiber Optic Pigtails

Choose Fiber Type，singlemode Or Multimode
Single-mode fiber pigtail uses 9/125um fiber, multi-mode fiber pigtail uses 50/125um or 62.5 /125um optical fiber.We mainly use single-mode pigtails for long-distance data transmission. Multimode pigtails are mainly used for short-distance transmission.Generally, the jacket of single-mode pigtails is yellow, and the jacket of multi-mode pigtails is orange.

Choose The Right Length Of Pigtail
The pigtail length of the optical fiber varies, but the length is usually less than 2 meters.You should select the appropriate cable length based on the distance between the devices.

Choosing The Right Type Of Connector Polish (UPC / APC)
The optical performance of APC connectors is generally better than that of UPC connectors due to the lower loss.In the current market, People widely use APC connector in more return loss sensitive applications such as FTTx, PON and WDM.However, APC connectors are usually more expensive than UPC connectors, so you should consider whether you need an APC connector based on your situation.APC should be a consideration for those applications where a high precision fibre optic signal is required, but other less sensitive systems will perform equally well with UPCs.

Choosing The Right Jacket Material (PVC / LSZH )
The conventional pigtail sheaths are LSZH and PVC, the PVC patch cord sheaths are the common ones with average fire resistance and low price; the LSZH patch cord sheaths means low smoke and halogen free materials, which are more environmentally friendly and flame retardant, but more expensive. You can choose according to your own situation.

Technology For Installing Fiber Optic Pigtails

Splicing Methods

One of the key aspects of installing fiber optic pigtails is the splicing method used. Fusion splicing is often preferred as it provides a low-loss connection that is suitable for high-performance applications. Mechanical splicing is another option, although it typically results in higher insertion loss. Careful consideration should be given to the type of splicing method used, as it can have a significant impact on the overall performance of the fiber optic pigtails.

Handling Procedures

Proper handling procedures are crucial when installing fiber optic pigtails. It is important to ensure that the pigtails are not bent beyond their minimum bend radius, as this can lead to increased signal loss and potentially damage the fiber. Additionally, care should be taken to avoid any contamination of the fiber optic connectors, as this can also lead to performance issues. Using clean and lint-free tools and materials can help to minimize the risk of contamination during the installation process.

Best Practices

In addition to splicing methods and handling procedures, there are several best practices that should be followed when installing fiber optic pigtails. This includes carefully routing the pigtails to minimize stress on the fibers, securing the pigtails with appropriate strain relief to prevent excessive tension, and ensuring that all connections are properly aligned and securely fastened. It is also important to conduct thorough testing and inspection of the installed pigtails to verify their performance and identify any potential issues.

How to Maintain Fiber Optic Pigtails

Do not bend the optical fiber jumper beyond its minimum bending radius, especially in the narrow space of high-density optical fiber wiring.
Use appropriate tools to redesign the fiber jumper path to protect the cables from damage, such as horizontal cable management racks.
Do not hit the optical fiber connector, otherwise the end face may be worn, and the fragments will pierce the skin. Therefore, it is recommended to put a dust cap on the jumper at any time.
For equipment to detect and identify faults, such as damage and full attenuation inside the fiber jumper, optical time domain reflectometer (OTDR) and fiber microscope can be used.
