Pigtails are also called bare optical fibers and pigtails. One end of the pigtail has a fiber optic connector, and the other end is a broken end of the fiber optic cable core. Fiber core stubs are fused to minimize insertion loss. The structure of pigtails and jumpers is very similar. In simple terms, the jumper is cut from the middle to form two pigtails. Pigtails have a variety of different connectors, common pigtails are usually 0.9mm in diameter and installed in the ODF unit.Pigtails are mainly divided into single-core pigtails, dual-core pigtails, 4-core pigtails, 12-core bundled pigtails, 12-color bundled pigtails, SC bundled pigtails, FC bundled pigtails, and LC bundled pigtails fiber and ST bundled pigtail, etc. There are many types of pigtails supplied by Shengwei cable:Multimode (OM1, OM2, OM3), single mode (OS2) according to fiber mode;There are single fiber, double fiber and multiple fibers according to the number of fibers;There are PC, UPC and APC according to the type of grinding and polishing of the connector.Pigtails have an outer jacket that protects tightly buffered cables from damage. The outer jacket can be easily stripped when space permits, so the pigtail has a tighter bend radius and takes up less space.In addition, pigtails are divided into single-mode pigtails and multi-mode pigtails, which can be distinguished by color, wavelength, and transmission distance. The color of the outer sheath of the multimode pigtail is orange OM1/OM2 and lake blue OM3, the wavelength of the multimode pigtail is 850nm, the transmission distance is 500m, and it is used for short distance connection; while the outer sheath color of the single mode pigtail is yellow , the wavelength is 1310nm or 1550nm, and its transmission distance is longer, up to 10km or 40km.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables, fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!

Often customers require optical fiber jumpers with particularly low insertion loss. For example, two days ago, a customer customized APC patch cords, and the insertion loss was less than 0.1dB. Such high-level jumpers can be produced, but the cost is higher than telecom-level jumpers. So is the insertion loss of the optical fiber patch cord as small as possible? the answer is negative.Optical fiber patch cords are used as devices for patching signals and connecting optical paths. The smaller the insertion loss, the smaller the attenuation, but the blind pursuit of excessive optical parameter requirements. The materials and processes of optical fiber patch cords must be greatly improved, which requires a high cost. The cost, the price/performance ratio is inappropriate. In the design of the optical system, the design power of the light source will have a reserved amount, which is greater than the power actually used. Through optical attenuators, optical splitters and other devices, the power is reduced to the power required for actual use. Therefore, the insertion loss of the optical fiber jumper used as a connection can meet the requirements of carrier-grade. If you want to make the performance of the jumper better, such as the interchangeability, reliability, and consistency, it is recommended that the customer use the jumper end face over-interference (3D) fiber jumper, which is now a high-standard jumper in the world.

Optical fiber is short for optical fiber. It is a fiber made of glass or plastic and can be used as a light transmission tool. The transmission principle is'total reflection of light'.The optical fiber communication system is a communication system that uses light as the carrier wave, uses extremely thin glass to draw extremely thin optical fibers as the transmission medium, and uses light to transmit information through photoelectric conversion. Communication using optical fiber is called optical fiber communication.Optical fiber transmission has many outstanding advantages:1. Frequency bandwidth: The width of the frequency band represents the size of the transmission capacity. The higher the frequency of the carrier, the greater the bandwidth of the signal that can be transmitted;2. Low loss: when transmitting 1.31um light, the loss per kilometer is below 0.35dB. If 1.55um light is transmitted, the loss per kilometer is even smaller, reaching below 0.2dB;3. Light weight: The optical fiber is glass fiber with small specific gravity, which makes it have the characteristics of small diameter and light weight, and it is very convenient to install;4. Strong anti-interference ability: Because the basic component of optical fiber is quartz, it only transmits light, does not conduct electricity, and is not affected by electromagnetic fields. The optical signals transmitted in it are not affected by electromagnetic fields. Therefore, optical fiber transmission has an impact on electromagnetic interference and industrial interference. Strong resistance;5. High fidelity: Because optical fiber transmission generally does not require relay amplification, it will not introduce new nonlinear distortions due to amplification. As long as the linearity of the laser is good, the TV signal can be transmitted with high fidelity;6. Reliable working performance: The optical fiber system contains a small number of equipment (unlike a cable system that requires dozens of amplifiers), and the reliability is naturally high. In addition, the life of the optical fiber equipment is very long, and the trouble-free working time is up to 500,000 ~750,000 hours;7. The cost continues to drop: As the source of the material (quartz) used to make the optical fiber is very abundant, with the advancement of technology, the cost will be further reduced.As a mainstream method of broadband access, optical fiber has the advantages of large communication capacity, long relay distance, good security performance, strong adaptability, small size and light weight, wide source of raw materials and low price. The application is more and more extensive.Common optical fiber specifications are:Single mode: 8/125μm, 9/125μm, 10/125μmMultimode: 50/125μm, (European standard), 62.5/125μm, (American standard)At present, the optical fibers used in optical fiber communication systems include quartz optical fibers, plastic coated optical fibers, single-mode optical fibers, and multi-mode optical fibers.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables,fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!

Carrier-grade fiber optic patch cords are widely used in data centers. In recent years, high-density data center fiber optic transmission systems have shown a high-growth trend in bandwidth requirements. Therefore, the use of a new generation of optical fibers and optical modules can continue to explore the growth of optical fiber network bandwidth. potential. Because multi-mode fiber jumpers have great advantages in cost, they have an absolute advantage in data center applications.Driven by the continuous application and promotion of network media in the cloud computing environment, multimode fiber optic patch cords are also constantly developing. From OM1 to OM2, and from OM3 to OM4, the VCSEL laser optimization technology used, and bandwidth requirements are constantly increasing.In 40G/100G data transmission applications, transmission port connection equipment, such as QSFP optical modules, no matter how many optical fibers are used to connect the high-density data center optical fiber, and no matter what type of optical fiber is connected, it will be directly connected through the MTP/MPO connector connect. Because the 40G/100G data transmission application device and the channel connection between the device need to form a special mode, so that the channel of the transmitting end and the receiving end of the device correspond to each other, which requires the MTP/MPO connector to complete the connection.Carrier-grade fiber optic patch cords can provide various applications for all networks and equipment that require 100G modules. They adopt the MT series sleeve design of the high-density multi-mode fiber optic connector system industry. MPO/MTP fiber jumpers use UPC and APC polished end faces, and support both multi-mode and single-mode applications. With VCSEL laser and LED light source, 10G OM3/OM4 MPO/MTP fiber patch cords can provide 10Gbps data transmission rate in high bandwidth applications. They are 5 times faster than standard 50um fiber patch cords. At present, MPO/MTP high-density push-pull optical fiber jumpers are mainly used in three aspects: high-density cabling data centers, fiber to the home, and connection applications with optical splitters, 40G/100G QSFP+, SFP+ and other optical modules. Today, there are already a series of high-density parallel optical interconnection products that can adapt to the optical fiber transmission of modern data centers, such as custom MPO/MTP fiber jumpers, multi-mode fiber loopbacks and QSFP+ high-speed cable assemblies.Fiber hope fiber optic cable and patch cord manufacturers can provide high-quality fiber optic cables,fiber pigtails, fiber patch cords, single-mode multi-mode fiber, welcome to inquiry!
