模块式四芯光纤信道分束器及其性能测试方法
Modular four-core optical fiber channel beam splitter and its performance test method
摘要
Abstract
Addressing the shortcomings of traditional multi-core fiber beam splitters and multi-core fiber connections,such as dif-ficulties in disassembly and the need for additional test beam splitters in testing solutions,a four-core fiber channel beam splitter is prepared using a double-clad fiber bundle tapering method.To facilitate device testing and connection,LC/PC-type active con-nectors are prepared at the ends of the single-mode fiber and the four-core fiber,thus forming a single modular four-core fiber channel beam splitter.Meanwhile,a mirror-based testing method is proposed for this modular device.This testing method re-quires only one LC/PC active connector-type mirror to easily complete the testing of the device's insertion loss and inter-core crosstalk.The test results indicate that the prepared four-core fiber channel beam splitter exhibits excellent performance,with a maximum insertion loss of 0.84 dB and a maximum inter-core crosstalk of-46.32 dB.关键词
