fiber optic patch cords are widely used in data center network cabling systems as a data transmission medium. Different interface types and different transmission distances are suitable for different application scenarios. Do you know which fiber jumpers to choose under which circumstances? This article will use data center-level LC-LC fiber optic patch cords. Take an example to explain how to choose a suitable fiber patch cord. Requirements for fiber patch cord in data centers (1) In recent years, the bandwidth requirements of data centers for network transmission systems have continued to increase, which has also led to continuous enhancement of the performance of fiber optic patch cords. According to different needs, the types are also increasing.
Such as: LC ultra-low insertion loss single-mode fiber optic patch cords, LC ultra-low insertion loss multi-mode fiber optic patch cords, LC one-tube dual-core fiber optic patch cords, LC bend-insensitive fiber optic patch cords, etc. (2) Ultra-low insertion loss single-mode fiber jumpers have a longer transmission distance than ultra-low insertion loss multi-mode fiber optic patch cords, and ultra-low insertion loss multi-mode fiber optic patch cords have lower cost than ultra-low insertion loss multi-mode fiber optic patch cords. The dual-core fiber optic patch cords maximizes space utilization, and the bend-insensitive fiber optic patch cords has the strongest anti-interference ability. (3) Different LC fiber optic patch cords meet the different needs of data centers. At present, the classification of LC fiber optic patch cords can meet most of the requirements of data centers. It can be said that LC-LC fiber optic patch cords have great advantages in data centers.
Advantages of LC-LC fiber optic patch cords (1) Compared with fiber optic patch cords with other interfaces, the interface of LC fiber optic patch cords can show excellent performance in most environments and can be used in most environments. It can bring great convenience in use. (2) From the above detailed classification and applicability, it can be seen that in the design and development, the LC fiber jumper is constantly improving its own performance, such as: ultra-low insertion loss, improving the utilization of space, simplifying the polarity conversion process, reducing Sensitivity, etc., and constantly provide the best solution for high-density applications in data centers. Data center grade LC-LC fiber patch cord solutions (1) LC ultra-low insertion loss fiber patch cords LC ultra-low insertion loss fiber patch cords are divided into single-mode and multi-mode, fast (FS) ultra-low insertion loss single/multiple Mode fiber jumpers are all connected with class B, and class B connectors can ensure ultra-low insertion loss, optimal return loss, effectively reduce the error rate, and ensure the reliability of transmission. The reference data of the B-class connector in IEC 61753-1 is the average value ≤ 0.12dB, the maximum value of more than 97% of the samples is ≤ 0.25dB, and the fast (FS) 0.12 dB low insertion loss is a typical B-class connector. (2) LC one-tube two-core fiber jumper One-tube two-core fiber jumper allows bidirectional transmission in a single fiber. Compared with conventional jumpers, it saves time and cost in fiber cabling and is more flexible in management. , The wiring is more convenient, and its unique design meets the interconnection and cross-connection of high-density application data centers, and provides the best solution for private networks and internal installations. Fei Suu (FS) one-tube duplex fiber patch cord adopts special "circular duplex" patch cord, which provides the best insertion loss and return loss, and ensures the stability of its transmission. Its unique improvement to the traditional jumper can save the wiring space while flexibly wiring. (3) LC bend-insensitive fiber jumper The LC bend-insensitive fiber jumper has the characteristics of low loss and high transmission rate, and the attenuation of the bending attachment in the long wavelength band is very small. Even if the bending radius is 7.5mm, the additional loss of the 1625nm window is only There is 0.8dB, which can fully meet the special requirements of small-sized optical devices and high-density applications for bending performance.
Fast Speed (FS) Bend Insensitive Fiber Patch Cables are grooved to reduce fiber loss when the cable is bent. Its product quality, mechanical properties, and optical properties have the same specifications as conventional optical fiber patch cords, and in addition, when the cable is bent, it can also maintain the additional function of optical performance.
