Brand Name:GONGFENG Model: SC/APC cold connector Length: 58mm Insertion loss: ≤0.3 (dB) Return loss: ≥50 (dB) Number of insertions and removals: ≥1000 Size: 9*62 (mm) Scope of application: Fiber to the home project Fiber type: Fiber G657A2/ 50/125, 62.5/125 mode, single mode, multimode performance The performance of fiber optic connectors, first of all, optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and number of insertions and removals of fiber optic connectors. 1. Optical performance: For the optical performance requirements of fiber optic connectors, the two basic parameters of insertion loss and return loss are mainly. Insertion Loss is the loss of the effective optical power of the link caused by the introduction of the connector. The smaller the insertion loss, the better. Generally, the requirement should be no more than 0.5dB. Return Loss (Reflection Loss) refers to the ability of the connector to suppress the reflection of the link optical power, and its typical value should be no less than 25dB. In the practical application of the connector, the surface of the pin has been specially polished to make the return loss larger, generally not less than 45dB. 2, interchangeability, repeatability The fiber optic connector is a universal passive device. For the same type of fiber optic connector, it can be used in any combination and can be used repeatedly. Therefore, the additional loss introduced is generally less than 0.2 dB. 3, tensile strength For a good fiber optic connector, the tensile strength is generally required to be no less than 40N. 4, temperature Generally, fiber optic connectors must be able to operate at temperatures between -40 ° C and +70 ° C. 5, the number of plugs Fiber optic connectors currently in use can be plugged and unplugged more than 1000 times. Common species According to different classification methods, optical fiber connectors can be divided into different types. According to different transmission media, they can be divided into single-mode fiber connectors and multi-mode fiber connectors. According to different structures, they can be divided into FC, SC, ST, and D4. , DIN, Biconic, MU, LC, MT and other types; according to the pin end face of the connector can be divided into FC, PC (UPC) and APC; according to the number of fiber cores, there are single core, multi-core and multi-core .
