CoaXPress-over-Fiber 是什么?
CoaXPress-over-Fiber 是什么?

CoaXPress-over-Fiber 是对现有 CoaXPress 规范进行的较少但却很重要的扩展,旨在支持光纤传输。

CoaXPress (CXP) 是高带宽计算机视觉应用的实际标准。CoaXPress 2.0 是该规范的最新版本,它指定了 CXP-12 速度,即同轴铜缆上的 12.5 Gbps(千兆位/秒)链路。由于链路聚合在 CoaXPress 中很常见,因此四条 CXP-12 链路可以轻松实现 50 Gbps (12.5 x 4) 的带宽。CoaXPress 规范由 JIIA(日本工业成像协会)主持。

CoaXPress-over-Fiber 是 CoaXPress 2.0 规范的附加部分。它提供了一种通过标准以太网连接(包括光纤)运行未经修改的 CoaXPress 协议的方法。因此,CoaXPress-over-Fiber 虽然使用的是为以太网设计的标准电子设备、连接器和电缆,但所采用的协议既不是以太网,也不是 GigE Vision,而是 CoaXPress。

使用光纤有何优缺点?


优点

  • 首先,由于光纤连接长度基本不受限制,因此电缆长度不再是问题。
  • 光纤提供更高的带宽,如今每条光纤的标准连接速度为 10 Gbps 和 25 Gbps,并且在数据中心得到广泛使用。
  • 光纤不受电噪声的影响,对于生产车间和某些医疗应用而言,这是一大重要优势。
  • 光纤比同等的铜缆更轻便、小巧,很适合于必须具备这一特点的应用,例如飞机或车辆。

缺点
  • 不能“通过光纤传送电能”。由于光纤中的信号通过光传输,因此无法通过光纤传送电能,诸如相机等设备必须单独供电。


CoaXPress-over-Fiber 的抖动和延迟是多少?它们与“传统”CoaXPress 相比如何?

CoaXPress-over-Fiber 基于 CoaXPress 协议,在抖动和延迟方面,其性能与 CoaXPress 一样高。另外,CoaXPress-over-Fiber 比 CoaXPress 支持的传输速度更高,因此这些版本中的抖动和延迟将得到进一步改善。


CoaXPress-over-Fiber 标准的状态如何?

截至2021年2月
Euresys和Sensor to Image的CoaXPress-over-Fiber于2018年开始开发,并于2021年2月获得CoaXPress工作组的最终批准并纳入标准。
Euresys事先预料到会获得批准,因此已准备好向相机制造商/集成商提供CoaXPress-over-Fiber桥接IP核以及四路CoaXPress-over-Fiber采集卡(QSFP+)以供评估和集成。
CoaXPress工作组覆盖日本工业成像协会(JIIA)领导下的大多数主要视觉机器制造商。

CoaXPress-over-Fiber 的电缆选择有哪些?
CoaXPress-over-Fiber 的电缆选择有哪些?

CoaXPress-over-Fiber 最重要的优势之一,就是众多公司已提供多种连接选择。10 Gbps CoaXPress-over-Fiber 和 Coaxlink QSFP+ 的的初始连接选择有 SFP+ 和 QSFP+(Quad 或四倍 SFP+)模块。 相较于固定接口,使用模块的优势在于可以根据应用要求为端口配备任何合适类型的收发器。由于可以使用的发送器和接收器类型多样,因此用户可以选择合适的收发器,通过多模或单模光纤提供所需的光学范围。
