马克的拳击手, OFS Technical Manager, reveals what makes Rollable丝带 so special. To form these ribbons, fibers are partially bonded to each other at intermittent points. This design not only enables mass fusion ribbon splicing but allows for easier individual fiber breakout than flat ribbons. The preferential bending plane of the rollable ribbons facilitates rolling 和 routing in smaller closures 和 splice trays, 类似于单个纤维.
Hi. 我是OFS的马克·鲍克瑟. Today I’d like to talk about Rollable丝带 和 if you haven’t seen it before, 就是这些东西, 这很简洁. It collapses upon itself when it’s rolled into a tight cylinder so you can kind of collapse it.
And then you can also easily separate it out to pull out an individual fiber. 那么，我就这么做，再靠近一点. So you can see that 和 then it just snaps back into place so you can slice it again. 所以，它像缎带一样拼接. 它可以很卷, 非常严格, 提供紧纤维密度的能力在一个非常, 非常小的包装.
所以，你把它和平坦的丝带比较. This is a flat ribbon 和 so t在这里 is no t在这里 is no moving of this or no rolling this without breaking the ribbon. 为什么这很重要呢?这又回到几何上了. 这是864光纤中心到扁平带状电缆. So, 如果你仔细看, you can see that t在这里 is a lot of space in between the flat ribbons 和 the tube.
那是因为我们的丝带基本上是矩形的. 电缆基本上是一个圆. When you have a circle 和 a rectangle, then it those don’t fit that efficiently. 如果你看看这条有864根纤维的电缆的可卷曲版本, you can see 在这里 t在这里’s not very much space between the fibers 和 the tube.
Rollable丝带 was dreamed up in Japan back in the 2000’s 和 went through a development path that was actually similar to the SC Connector that happened in the early 1990s.
And what I mean by that is that NTT in Japan farmed out the concept to various companies who ultimately brought it to market. 对于Rollable丝带母公司OFS的情况, Furukawa was one of those companies that introduced Rollable丝带 和 so we brought it back to brought it to market during the middle part of the 2010’s.
所以Rollable丝带有很多好处. 你知道, 我们在很多不同的环境中都看到过, 我把这叫做使用可滚动丝带的自助餐. 它是小的. 丝带本身很小，所以可以卷起来. That means that cables can be much smaller 和 lighter for a given size.
这样就可以将更多的纤维放入更小的导管中. It can mean smaller h和 holds more cable on a real for longer lengths or fewer slice points. 然后是空中装置，因为所有的东西都更小, 也减轻了杆上的重量, 形成的冰更少了. 一般来说，越小越容易. Some customers like it because it can be placed in thinner slice trays enabling more trays 和 a closure or a smaller closure for a given fiber count.
All of these cables are gel free, so they’re easier to prepare for slicing. 当然，这些是缎带. 所以一次可以有12个大质量的融合. The initial installations were primarily used to connect data centers together because data centers use very high fiber count cables, 你知道, 想想1728年, 3456s.
But what I’m really excited about is the concept of using rollable ribbons in lower fiber count networks. 包括光纤到户、骨干和分销网络. 对于这些应用程序, 我们通常使用, lose tube cables in the past because it’s easier to pull out an individual fiber to connect a subscriber. But now with Rollable丝带, it’s easier to pick out an individual fiber versus a loose tube. The ribbons or clearly marked, the fiber color is always going to be in the same place. 你只要挑出你需要的东西.
So now the cables can be smaller, they can be easier to work with in the field. 如果你比较一下这288根光纤算电缆. 首先是一个松动的管子. 它实际上相当大. 这是一条平坦的带状电缆288.
So now look at the rollable – 和 so we’ve got a couple of different versions of this but actually the larger rollable you can see that even the larger rollable is much smaller than either the loose tube or the flat ribbon.
OFS now offers users more ways to double their optical fiber density by exp和ing the AccuTube®+ Rollable丝带 Cable product family. 这些新电缆有432, 576和864纤维具有可卷曲的缎带, OFS最新的光纤带设计. 这些电缆是100%无凝胶的, 全介质单护套和轻护套结构.
可卷曲带状纤维 optic cables are one of the most exciting developments in outside plant (OSP) cabling in years. These cables can help users gain substantial time 和 cost savings with mass fusion splicing. And they also double the fiber density in a given size duct compared to traditional flat ribbon cable designs.
Each OFS rollable ribbon features 12 individual 250 µm optical fibers that are partially bonded to each other at predetermined points. These ribbons can be “rolled” into a flexible 和 compact bundle that offers the added benefit of improved fiber routing 和 h和ling in closure preparation.
This completely gel-free cable design also helps to reduce the time needed for splicing preparation by up to 80%. 除了, these rollable ribbon cables are smaller 和 weigh at least 35% less than conventional flat ribbon cables. This reduced weight improves cable h和ling 和 also helps to relieve the tension placed on installation poles.
The AccuTube+ Rollable丝带 Cable product portfolio also features cables with 1728 fibers in both single jacket 和 light armor designs 和 3456 fibers in a single jacket construction. All of these cables meet or exceed the requirements of Telcordia GR-20 issue 4.
凭借其最大限度地利用管道的能力, the AccuTube+ Rollable丝带 Cable is an excellent choice for connecting data centers, 并作为密集以前或移动网络的分布. 要了解更多beat365登录这些电缆的信息，请访问 在这里 和 在这里.
