摘要

空分复用技术是提高光通信系统传输容量的有效方法之一，主要技术包括多芯光纤（MCF）、少模复用和轨道角动量复用等，其中MCF技术是空分复用技术中较成熟的一种。

【目的】

为解决光通信传输系统中容量受限的问题，文章设计和研制了一种新型的4芯光纤波分复用（WDM）器件。

【方法】

文章首先对WDM、空分复用、MCF和MCF耦合技术等进行分析，选取了以毛细管、透镜和腐蚀光纤方案制作的4芯扇入扇出器件为媒介，然后利用MCF和WDM技术相结合的方法，从4芯光纤的选取、4芯WDM调试原理和调试方法出发，最后利用4芯扇入扇出器件设计和研制了一种新型的4芯WDM原样，并利用4芯扇入扇出器件使用差值法对文章研制器件进行了指标测试。

【结果】

根据实验样品测试的结果显示，该4芯WDM原样1的各反射端和透射端的插入损耗能够控制在0.8 dB以内，反射端的各路隔离度>15 dB，透射端的各路隔离度≥40 dB。

【结论】

根据测试结果可得到以下结论：与传统单芯WDM方案相比，在同样器件体积下，新型4芯WDM原样可以实现4路通信，极大地提高了光通信容量，同时，填补了国内外对基于MCF技术的空分复用光器件研究的空缺，并且拓展了空分复用的应用范围，让MCF具有长距离传输的潜能。基于空分复用系统制作的WDM器件，在光纤通信系统中具有广泛的应用前景。

Abstract

Space division multiplexing technology is one of the effective ways to improve the transmission capacity of optical communication system. The main technologies include Multi Core Fiber (MCF)

few mode multiplexing and orbital angular momentum multiplexing

among which MCF technology is a mature one.

【Objective】

To solve the problem of capacity limitation in optical communication system

this article designed and developed a new four-core Wavelength Division Multiplexing (WDM) original sample.

【Methods】

Firstly

the technology of WDM

air division multiplexing

MCF and multicore fiber coupling is analyzed. The four core fan-in fan-out device made with capillary

lens and etch fiber is selected as the medium. Then

by combining MCF technology and WDM technology

starting from the selection of four-core fiber

the debugging principle and debugging method of four-core WDM

a new four-core WDM original sample is designed and developed by using four-core fan-in fan-out device. The index of the device is tested by using the difference method of four-core fan-in fan-out device.

【Results】

According to the test results of the experimental samples

the insertion loss of each reflection end and transmission end of the original four-core WDM 1 can be controlled within 0.8 dB

the isolation degree of each reflection end is >15 dB

and the isolation degree of each transmission end is ≥ 40 dB.

【Conclusion】

According to the test results

the following conclusions can be drawn: compared with the traditional single-core WDM scheme

the new four-core WDM can realize four-channel communication under the same device volume

and greatly improve the optical communication capacity. At the same time

it fills the gap in the research of air division multiplexing optical devices based on MCF technology and expands the application range of air division multiplexing

demonstrating the potential of multi-core fiber based long-distance transmission. WDM device based on space division multiplexing system has a wide application prospect in optical fiber communication system.
