Grade B Patch Cord



T&S grade B patch cord connector is the patchcord with the random mating performance of Grade B as IEC-61753-1 defined, more than 97% of maximum 0.25dB random mated with each other and the average is less than 0.12dB. Simplex, duplex grade B patchcord is well fabricated and all grade B connectors (including LC, MU, SC, FC, etc.) are compliant to IEC-61754, end face geometry is superior to IEC-61755. As an experienced fiber patch cord manufacturer, T&S provides high-quality grade patch cable b connector for years.





Grade B Patch Cord Basic Info

With the advances in 5g fiber optic technology and transmission systems, reliable cabling systems are becoming even more important. Active optical equipment, which is often worth hundreds of thousands of dollars, is all connected to the network via the humble optic fiber patch cord or patch lead. The risk of network downtime due to unreliable cabling is one that should be avoided. Therefore, these types of networks, along with many other Data Center and high-speed Commercial networks require reliable patch cord connector infrastructure in order to maximize performance and to ensure long-term reliability.

Optical Fiber Connector Grades of Grade B Patch Cord Connector

IEC standards dictate the patch cord connector performance for each grade of fiber-optic patch cord connector based on IEC 61753-1. As defined, there are four grades for insertion loss from A (best) to D (worst). For conventional patch cord connector, mated performance is over 0.5dB, even to 1.0dB. This may cause the whole high-speed optical connection system unreliable and transmission unstable. Therefore, the grade B patch cord connector is stable with the excellent optical performance of a maximum 0.25dB while mating each other which is a guarantee for hundreds of gigabit data exchange with connections.

  The optical fiber communication connector is composed of ceramic ferrule and connector kits. different types of connector kits and ferrules are pre-assembled according to different optical connector types . During patchcord production, optical fiber patchcord or pigtails can be quickly produced with optical cable, and to a certain extent, the production processes of optical fiber cables is less and the efficiency is therefore improved.   For more information   about fiber cable connector types ,  please feel free to contact us!   There are many fiber optic component manufacturers , but we are one of the best choices for you.

Fiber Stub

图片
Fiber Stub is a ceramic (zirconia) capillary assembled with optical fiber. It is the most important component when connecting receptacle Modules such as TOSA and ROSA assemblies. Fiber stubs are fitted into the receptacle modules to achieve a stable connection with the fiber stub and fiber connectors when the two mates in the receptacle. T&S Communications Fiber Stubs are manufactured with high-quality ceramic ferrules. They usually be polished with PC or APC end-face. Standard diameters are 1.25mm or 2.5 mm, and other sizes may also be available. T&S Communications provides high quality and reliable fiber stub for TOSA/ROSA Receptacle. As an optical fiber manufacturer , we have a proven polishing process using specially designed high precision machines. With an experienced manufacturing process, T&S Communications fiber stub delivers the highest performance and lowest defect rate.
