4-Core MCF Multicore Fiber Patch Cord Assembly
Integrated Core Branching Device, Ready for Commercial Deployment
Focusing on the core requirements of high-density cabling and high-speed optical interconnection, Hengtong Optic-Electric has been actively advancing the development of 4-core multicore fiber, or MCF, patch cord assemblies. The product has now successfully completed a full set of product-level validations, with all performance indicators meeting the delivery standards required to move from the laboratory to the market. It has officially entered a key stage of industrialization.
Multicore fiber branching product
Hengtong's 4-core MCF patch cord assembly integrates a built-in multicore fiber fan-in/fan-out core device. This device is a critical supporting component for the precise branching of multicore fiber cores. Its primary function is to smoothly split a combined multicore fiber containing four integrated cores and accurately map each core to a single standard optical fiber branch.
This enables efficient connection and fan-out between multicore fibers and single-core fibers, ensuring that core signals are separated without interference or excessive loss. As a result, it serves as an essential core component for the engineering application of multicore fiber systems.
At this stage, Hengtong Optic-Electric is actively preparing to conduct joint compatibility work with mainstream optical module manufacturers. At the same time, it is launching full-link integration testing and comprehensive performance verification to validate key indicators such as transmission stability and core-matching accuracy in real network environments.
These efforts will build a solid technical and application foundation for the future large-scale commercialization of 4-core MCF multicore fiber in high-speed optical interconnection and high-density cabling scenarios.
Multicore Fiber Fan-In/Fan-Out Device
Dedicated Fiber Core Branching Component with Four Key Advantages
As the built-in core component of the 4-core MCF multicore fiber patch cord assembly, the multicore fiber fan-in/fan-out device is a critical foundational device for enabling efficient coupling and line branching between multicore fibers and standard single-core fibers. It performs the core functions of fiber core splitting and optical line connection.
Based on the application characteristics of multicore fiber, Hengtong Optic-Electric uses dedicated special fabrication technologies and precision modular packaging processes to manufacture this device. Its core advantages are clear:
Low loss ensures that optical signal loss remains extremely low during fiber core branching and transmission, maximizing signal transmission efficiency.
Low crosstalk effectively prevents interference among the four fiber cores, ensuring clean and stable transmission on each optical channel.
High return loss greatly reduces signal reflection, helping avoid link fluctuations and transmission distortion.
High reliability is achieved through strict process control, ensuring stable performance during long-term operation and under complex working conditions, while protecting the safety of the optical path throughout the system.
MPO Pre-Terminated Dust-Proof Module Box
Dedicated Optical Path Protection Accessory for Reliable Operation and Maintenance
To support the long-term stable operation of multicore fibers and patch cord assemblies in real-world environments, Hengtong Optic-Electric has developed targeted MPO dust-proof pre-terminated products based on customers' on-site application requirements.
In common application environments such as equipment rooms, server cabinets, and low-voltage electrical rooms, dust and debris can easily enter fiber interfaces and cause end-face contamination, abnormal optical attenuation, or even transmission interruption. To address these risks, Hengtong has optimized the sealing structure and upgraded its professional protection process.
The supporting MPO module box achieves IP5-level dust protection, effectively preventing external dust and fine particles from entering internal interfaces and components. The product also adopts a customized development model, allowing it to fit server cabinets, equipment rooms, low-voltage rooms, and other operating environments.
This comprehensive protection capability meets customers' high standards for long-term optical path reliability and creates a strong protective barrier for the entire multicore fiber transmission system.
