Fiber patch cords are used to make patch cords from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box.
Pigtail, also known as pigtail, has only one end with a connector, and the other end is a broken end of a fiber optic cable core, which is connected to other fiber optic cable cores by fusion splicing. (couplers, jumpers, etc. are also used between them).
The optical fiber connector is a device for detachable (active) connection between optical fibers and optical fibers. It precisely butts the two end faces of the optical fibers, so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. And minimize the impact on the system due to its involvement in the optical link, which is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
Whether the insertion loss of the fiber jumper is as small as possible？
Customers often request to make fiber jumpers with particularly small insertion loss. For example, some customers customize APC jumpers, and the insertion loss is less than 0.1dB. Such high-grade jumpers can be produced, but the cost is higher than that of telecom-grade jumpers. So is the insertion loss of the fiber patch cord as small as possible? the answer is negative.
As a device for patching signals and connecting optical circuits, the smaller the insertion loss, the smaller the attenuation caused, but the blind pursuit of high optical parameters requires that the material and process of the fiber jumper must be greatly improved, which requires high costs. The cost is not suitable for the price/performance ratio. In the design of the optical system, the design power of the light source will have a reserved amount, which is larger than the actual power. Through the optical attenuator, optical splitter and other devices, the power is reduced to the power value required for actual use. Therefore, the insertion loss of the optical fiber jumper that acts as a connection can meet the requirements of the carrier level. If you want to improve the performance of the jumper, such as improved interchangeability, reliability, and consistency, it is recommended that customers use the fiber jumper with over-interference (3D) on the end face of the jumper, which is a high-standard jumper currently used internationally.
