What are the characteristics of leather fiber optic jumpers? Leather fiber optic jumpers are all prefabricated end products, and prefabricated end butterfly optical cables are just one of them.
The prefabricated butterfly cable is an optical fiber active connection device designed by the manufacturer for fiber-to-the-home (FTTH). It is prefabricated in the factory and provides an excellent alternative solution for the connection of leather cable.
The prefabricated butterfly cable can be used in conjunction with optical fiber cold splicing or fusion splicing to quickly realize the function of optical fiber splicing. Compared with optical fiber quick connectors, because it is a connector joint that is made by grinding in the factory, Therefore, the reliability, stability, service life, installation success rate, and technical indicators of the connection have been significantly improved; and the customized length is arbitrary, the construction and installation are fast, the maintenance is simple and convenient, and the overall cost is low.
In general, the production of prefabricated end leather cable needs to meet the following requirements:
1. Requirements for light decay:
a. Insertion loss ≤0.15db
b. Return loss ≥50 (UPC)
2. Butterfly cable requirements:
a. Fiber core requirements: single core, G.657A2(B6)
b. Sheath material: low-smoke halogen-free flame-retardant sheath, the minimum thickness is not less than 0.4mm (please specify the specific material type)
3. Joint style
The length of the prefabricated joint ≤ 58mm
The technical standard and appearance of prefabricated connectors are consistent with SC/UPC pigtails.
At present, most of the prefabricated end sheath optical cables in the market are self-supporting butterfly optical cables with connectors on both sides, that is to say, they are generally single-core, and there is no spare core.
