选择单模与多模光纤

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. OFS LaserWave系列的OM3, OM4 和 OM5 multimode fibers support application speeds ranging from 10 Gb/s all the way to 400 Gb/s 和 beyond. LaserWave WideB和 OM5 fiber offers extended reach for multi-wavelength WDM applications, 包括当前和未来的BiDi和SWDM4解决方案, 使其成为最具前瞻性的解决方案.

带宽是多模光纤最重要的参数之一, 哪一个定义了光纤的信息承载能力. OFS has led the way in developing 和 st和ardizing new 和 innovative ways to maximize 和 characterize fiber b和width for reliable system performance.

 
 

多模光纤常见问题（FAQ）

多模光纤是如何工作的?

多模光纤继续发展, 支持企业和数据中心网络的最新网络速度. Multimode technology has maintained its ability to provide the most cost-effective short reach links through a combination of fiber 和 optical component development that takes advantage of technology advances. 光纤带宽是这个等式的关键组成部分.

 

多模光纤的用途是什么?

Multimode optical fiber systems continue to be the most cost-effective fiber choice for shorter reach premises, 校园, 企业局域网, 数据中心应用, 射程可达500 - 600米. This is because multimode optics continues to be less expensive than single-mode optics. Beyond the reach of multimode optical fibers, it becomes necessary to use single-mode optical fiber.

 

单模光纤和多模光纤有什么区别?

的 way in which these two fiber types transmit light eventually led to their separate names. 一般设计用于中等到长距离(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. This tiny core requires precision alignment to inject light from the transceiver into the core, 显著提高收发器成本.

Multimode optical fibers have larger cores that guide many modes simultaneously. 更大的核心使得从收发器捕获光更容易, 允许控制源成本. 类似的, multimode connectors cost less than single-mode connectors as a result of the more stringent alignment requirements of single-mode optical fiber.

 

多模光纤的最大距离是多少?

多模光纤的传输距离取决于传输速率和收发器.  工业标准定义了使用给定收发器以给定数据速率到达的距离.  例如:

  • 100mb /s时2公里（100BASE-FX）
  • 1gb /s下1公里（1000BASE-SX）
  • 400 - 600米10gb /s （10GBASE-S）
  • 70 - 150米，数据速率范围从40到400 Gb/s.

Transceiver manufacturers offer extended reach transceivers to achieve even longer lengths, 避免使用更昂贵的单模光学器件.  在一般情况下, multimode optical fiber continues to be the most cost-effective choice for short reach applications.

 

什么是OM3、OM4和OM5多模光纤?

50µm激光优化多模（OM3）, OM4, 和 OM5) optical fibers offer significant b和width 和 reach advantages for short-reach applications while preserving the low system cost advantages of multimode optical fiber.

今天,62.5 µm OM1 multimode optical fiber is virtually obsolete 和 is relegated for use with extensions or repairs of legacy, 低带宽系统. 62.5µm OM1光纤在10G时仅支持33米, 它甚至不被认为是一个更快速度的选择.

 

为什么是OM5宽带?

WideB和 OM5 多模光纤 is a 50 micron (μm) laser-optimized multimode fiber designed to help meet the dem和ing requirements of today’s 850 nm based networks, as well as next-generation multimode short wavelength division multiplexing (SWDM) applications.  OFS’ LaserWave WideB和 OM5 fiber is designed to support light traveling at multiple wavelengths from 850 nm to 953 nm, 不像OM3和OM4光纤只针对单一波长进行了优化, 850海里操作.
