ABSTRACT Data exchange between wavelength restricted networks is a vital component of a communication link especially a data centre and the long-haul fibre network. Using VCSEL transmitters, we experimentally demonstrate an all passive bidirectional wavelength conversion based on electrical-to-optical-to-electrical driven transmitters whose transmission wavelengths are not restricted. In this study, a downstream 1550 nm VCSEL modulated at 8.5 Gbps is transmitted over 24 km SMF and its electrical data signal used to drive an 850 nm transmitter and transmitted over 50 m MM fibre. An upstream illustration by modulating an 850 nm VCSEL with 8.5 Gbps and driving a 1550 nm is similarly performed to represent a bidirectional wavelength conversion and quality of signal analysed at the 10−9 BER level. A 1.6 dB average penalty is incurred in this set-up due to the inter-modal dispersion experienced by the multimode-mode signals in the 850 nm wavelengths. This work provides a convenient, cheaper and efficient technique for integrating the short- and long-haul transmitted signals in backbone fibre-links.

用于长途和数据中心 VCSEL 光纤互连的双向和波长无限制转换

摘要 波长受限网络之间的数据交换是通信链路的重要组成部分，尤其是数据中心和长距离光纤网络。使用 VCSEL 发射器，我们通过实验证明了一种基于电-光-电驱动发射器的全无源双向波长转换，其传输波长不受限制。在这项研究中，以 8.5 Gbps 调制的下行 1550 nm VCSEL 通过 24 km SMF 传输，其电数据信号用于驱动 850 nm 发射机并通过 50 m MM 光纤传输。通过以 8.5 Gbps 调制 850 nm VCSEL 并驱动 1550 nm 的上行图示，类似地执行以表示在 10-9 BER 级别分析的双向波长转换和信号质量。1。由于 850 nm 波长的多模模式信号所经历的模间色散，在该设置中产生了 6 dB 的平均损失。这项工作为在骨干光纤链路中集成短距离和长距离传输信号提供了一种方便、便宜和有效的技术。
