Choosing Between 单模与 多模光纤

与单模相比, multimode fiber continues to be the more cost-effective 和 lowest power consumption fiber for short-reach applications (< 500 meters) due to generally cheaper 和 less power-hungry 850 nm VCSEL-based optics. 的 OFS LaserWave family of OM3, OM4和OM5多模光纤支持从10gb /s到400gb /s甚至更高的应用速度. LaserWave宽带OM5光纤为多波长WDM应用提供了更广泛的覆盖范围, including current 和 future BiDi 和 SWDM4 solutions, making it the most future-proof solution.

One of the most important multimode fiber parameters is b和width, which defines the information-carrying capacity of the fiber. OFS在开发和标准化新的创新方法方面处于领先地位，以最大限度地提高和表征光纤带宽，从而实现可靠的系统性能.

 
 

多模光纤 Frequently Asked Questions (FAQ)

How does multimode fiber work?

Multimode fiber continues to evolve, supporting the latest network speeds in enterprise 和 data center networks. 多模技术通过利用技术进步的光纤和光组件开发相结合，保持了其提供最具成本效益的短距离链路的能力. Fiber b和width is a critical component of this equation.

 

What is multimode fiber used for?

多模光纤系统仍然是较短距离场所中最具成本效益的光纤选择, 校园, 企业局域网, 和 data center applications, 射程可达500 - 600米. 这是因为多模光学仍然比单模光学便宜. 由于不能使用多模光纤，因此必须使用单模光纤.

 

What is the difference between single-mode 和 multimode fiber?

这两种光纤传输光的方式最终导致了它们各自的名字. Generally designed for systems of moderate to long-distance (e.g., 地铁, 访问, 和长途网络), single-mode optical fibers have a small core size (< 10 µm) that permits only one mode or ray of light to be transmitted. 这个微小的核心需要精确校准，以将光从收发器注入核心, significantly driving up transceiver costs.

多模光纤芯较大，可以同时引导多个模式. 的 larger core makes it much easier to capture light from a transceiver, allowing source costs to be controlled. 类似的, 由于单模光纤更严格的对准要求，多模连接器的成本低于单模连接器.

 

What is the maximum distance for multimode fiber?

Reach of multimode fiber is dependent on the data rate 和 transceivers used.  Industry st和ards define reaches at given data rates with given transceivers.  例如:

  • 2 kms at 100 Mb/s (100BASE-FX)
  • 1gb /s下1公里(1000BASE-SX)
  • 400 – 600 m at 10 Gb/s (10GBASE-S)
  • 70 – 150 m at data rates ranging from 40 to 400 Gb/s.

收发器制造商提供延伸距离收发器，以实现更长的长度, avoiding the need to use more expensive single-mode optics.  在一般情况下, 多模光纤仍然是短距离应用中最具成本效益的选择.

 

What is OM3, OM4, 和 OM5 multimode fiber?

50 µm laser-optimized multimode (OM3, OM4, 和OM5)光纤为短距离应用提供了显著的带宽和到达优势，同时保留了多模光纤的低系统成本优势.

今天,62.5µm OM1多模光纤实际上已经过时，只能用于扩建或维修, 低带宽系统. 62.5 µm OM1 fiber supports only 33 meters at 10G, 和 is not even recognized as an option for faster speeds.

 

为什么是OM5宽带?

宽带OM5多模光纤是一种50微米(μm)激光优化的多模光纤，旨在帮助满足当今基于850nm网络的苛刻要求, 以及下一代多模短波分复用(SWDM)应用.  OFS的LaserWave宽带OM5光纤设计用于支持850 nm至953 nm的多种波长的光传播, unlike OM3 和 OM4 fibers that are optimized for single wavelength, 850海里操作.
