Njia Moja na Multimode SC LC Fiber Optic Pigtails

Fiber optic pigtails create connections. Think of these as special wires made of glass, not copper. These cables have a connector already put on at the factory. You will find the other end bare.

You can join this end to another fiber cable. Fiber optic pigtails help connect different parts of a big network that uses light to send information. A thin, strong layer, only 900 µm thick, covers the glass. The center part, called the core, is very tiny, just 9 µm across.

Around the core is another layer called cladding, and this one is 125 µm. When joining, you want very little light to be lost, less than 0.2 dB. Also, we want to make sure that light doesn’t bounce back too much, preferably less than 55 dB. Fiber optic pigtails work with specific types of light, measured at 1310 nm or 1550 nm wavelengths. You can use these in cold places as cold as -20°C and hot places up to 70°C.The connector on the end is made of a hard material called ceramic.

There are different ways to polish the ends, like UPC. There is also APC, which is even better at stopping light from bouncing back. These are different kinds of glass fibers, like OS2. The outside cover is made of materials such as PVC. Fiber optic pigtails can send one or many light signals at once.

Comprehensive Connector Types for Fiber Optic Pigtails!

· SC (Subscriber Connector) Pigtails

Subscriber Connector pigtails have a simple way to connect and disconnect. The connector part makes it easy to plug in. A small, round piece inside, 2.5 mm wide, keeps things lined up. When using these fiber optic pigtails, only a little light is lost, about 0.25 dB. Light bouncing back is minimal, around 50 dB.

These work well in temperatures between -40°C and 75°C. Moreover, you can plug and unplug them 1000 times. The diameter of the ferrule is 2.5 mm. These are made using OS2 single-mode 9/125 fiber. The core is surrounded by 125 µm cladding. The jacket is made of PVC material. The typical length is 1 meter. A 900 µm tight buffer protects the fiber. A strain relief boot prevents bending.

· LC (Lucent Connector) Pigtails

Lucent Connector pigtails have very small connectors. Lucent Connector versions are half the size of Subscriber Connector ones. A tiny rod, just 1.25 mm wide, is inside. When connected, only 0.1 dB of light is lost. These fiber optic pigtails reflect very little light back, around 60 dB. Besides, they can handle temperatures from -40°C up to 80°C. You can connect and disconnect them 500 times.

A 900 µm tight buffer protects the fiber. A small strain relief boot is present. They are available in UPC polish. Insertion loss is less than 0.1dB. They are compliant with IEC 61754-20.

· FC (Ferrule Connector) Pigtails

Ferrule Connector pigtails have a special design that lets you screw them on tightly. Consequently, this makes sure they stay connected. Inside, there is a small, round piece that is 2.5 mm across. The light loss is very low, only 0.3 dB. Also, they prevent a lot of light from bouncing back, around 50 dB. You can use these fiber optic pigtails in places where it is between -20°C and 70°C.

Furthermore, they are good for 500 connections and disconnections. The ferrule is made from zirconia ceramic. These are OS2 single-mode 9/125 fibers. The core has a 9 µm diameter. The cladding diameter is 125 µm. The jacket uses PVC material. Standard lengths are available in 3 meters. These are available in both UPC and APC polish.

· ST (Straight Tip) Pigtails

Straight Tip pigtails have a connector that you can easily twist and lock. Accordingly, this makes connecting them simple. They have a small, round part inside that is 2.5 mm wide. They only lose about 0.3 dB of light when in use. These fiber optic pigtails keep the light that bounces back low, around 40 dB. You can use them where it is between -20°C and 60°C.

Additionally, you can connect and disconnect them 500 times. The ferrule is made from zirconia ceramic. The fiber type is OS2 single-mode 9/125. The core is 9 µm in diameter. The cladding is 125 µm in diameter. The jacket is made of LSZH material. They come in lengths of 1, 2, or 3 meters. The operating wavelength is 1310 nm or 1550 nm.

Precision Engineering in Our Fiber Optic Pigtails!

Auto manufacturing processes
Automated manufacturing processes in our fiber optic pigtails use robotic assembly. Therefore, this method maintains quality, and every pigtail has exact dimensions. Dimensions include a core alignment within 0.5 µm. Whereby, a concentricity of under 1 µm is maintained. Cable lengths have a tolerance of 1%. Ultimately, connector insertion loss variation is limited to 0.05 dB.
Premium zirconia ferrules
Premium zirconia ferrules in our pigtails feature top-grade zirconia ferrules. Therefore, this material provides hardness. Ferrules achieve a 1.25 mm or 2.5 mm diameter. Whereas, they have a surface roughness under 20 nm. Expect a radius of curvature between 10 mm and 25 mm. The apex offset is less than 50 µm in fiber optic pigtails.
Advanced polishing systems
Advanced polishing systems in our factory control pressure, including controlling the speed. This action shapes the fiber. Each step uses a specific grit. Forasmuch as, we achieve a scratch-free surface. Roughness is under 10 nm. The geometry meets industry specification. In entirety, this method guarantees a uniform polish of each ferrule surface. The apex is precise in fiber optic pigtails.

Installation and Handling of Fiber Optic Pigtails!

Preparation

Keep your workspace tidy. Ensure the area you’re starting to work in is clean before you start: this will prevent 900µm fiber contamination. Using quality fiber optic pigtails demands workspace tidiness. Check the optical power meter's calibration at 850nm, 1300nm, 1310nm, 1550nm. You should also verify the connector's 8-degree angle, plus confirm fusion splicer electrode alignment.

Splicing

Carefully strip back 1 meter, without damaging 9µm core. Afterward, you can place the 2.5mm ferrule into a v-groove. Achieving under 0.05dB loss, align, performing 10 splices. Consequently, protect each splice using a 60mm sleeve.

Cleaning

Without exception, using a 1.25mm tool for LC connectors will be essential. Then, for an SC connection, apply a 2.5mm stick, turning it halfway. For best results, handle fiber optic pigtails with proper tools. You should dispense a 2ml alcohol amount, employing 4x4-inch wipes. For FC types, activate a one-click cleaner thrice.

Ulinzi

Following setup, fasten each fiber optic pigtail inside a 19-inch rack. Then, splice points can be encased in 45mm sleeves. Utilizing color codes on 0.9mm fiber cables is important. Then, you must store unused items, guaranteeing humidity remains under 40%.

Maswali Yanayoulizwa Mara kwa Mara!

A fiber optic pigtail is a single, short optical fiber. One is connector at one end and bare fiber for splicing at the other. This fiber connects to a longer cable. A pigtail is used in telecommunications. Diameters typically measure 9/125 µm for single-mode. Lengths vary from 1 to 3 meters.
Connector types we offer are SC, LC, FC, and ST connectors. Subscriber Connector uses a push-pull method. Lucent Connector is smaller. These connectors are essential in fiber optic pigtails. Ferrule Connector has a screw-on design. Straight Tip uses a twist-lock. Each has different ferrule sizes. They range from 1.25 mm to 2.5 mm in diameter, coming in UPC or APC polish.
Pigtails are installed by first preparing the fiber end. Clean the fiber end. Cleave the end. Then, use a fusion splicer. This action fuses the pigtail to another fiber. Protect the splice joint. The optical power meter method is used to test the connection. The splice loss should be within limits, i.e. it should be less than 0.2 dB.
The difference is the core size. Single-mode fiber has a core of 9 µm. Single mode allows one light path. Multimode has a larger core, 50 µm or 62.5 µm. Multimode allows multiple paths. Single-mode is for long distances. Multimode is for shorter distances. They have different bandwidth capabilities.
Insertion loss and return loss are important. Insertion loss is the light lost in a connection. Loss is measured in dB. Fiber optic pigtails impact insertion and return loss values. Values should be low like 0.1 dB. Return loss is light reflected back. Return is also in dB. High values are desirable, like 60 dB. They show connection quality, measured during testing.
Custom-length pigtails are available. We make fiber optic pigtails to your desired length. You specify the end connector type. Also, you pick the fiber mode. We offer lengths from 0.5 meters to 10 meters. Each is tested to meet industry requirements for insertion loss. They are available in different jacket colors, including custom.
