2.5G以上SFP光接口的电缆跳线设计

摘要

Traditionally,the maximum transmission rate of the electricity-based SFP is 1G,lacking the technology and product to convey the 2.5 G&beyond high-speed links. At present,optical transmission is the primary way to support 2.5 G&beyond high-speed SFP links. Based on common cable materials,this paper employs electromagnetic field and circuits joint-simulations to design low-cost,high-quality SFP cable jumper in order to replace the 3G&below SFP fiber jumper which is composed of high-speed optical module and fiber.%目前2．5G以上高速SFP链路为光传输方式，基于电传输的SFP最大速率仅为1G，缺乏用于2．5G以上高速链路的技术和产品。本文基于普通电缆材料，采用电磁场与电路联合仿真技术，设计出低成本、高质量的SFP电缆跳线，可替代现有的3G以下的由高速光模块和光缆组成的SFP光跳线模块。
