This blog post is part of a new video blog series—Fiber Friday. Our subject matter experts will provide you with some insight into the world of fiber optics, covering various industry topics.

The introduction of bend insensitive fibers made the fiber-to-the-home network stand up and take notice. These fibers eliminated a lot of optical concerns; however, mechanical reliability and stability must still be maintained. So, how do you make your fiber network more stable

In this blog, I explain how too many sharp bends for an extended period of time can cause interference to your network’s stability.

what the difernt of OM4 AND OM5 ?

The fibers mentioned in the BLOG were indeed singlemode fibers for FTTH applications. For multimode fibers OM3 and OM4 the macrobend losses are strongly dependent on the launch conditions of the light source. When LED light sources are used then the fiber will be often "overfilled" (= all possible modes are existing) and then the transmitted signal is very sensitive for bending. The higher order modes are very sensitive for bending. Today the LED sources are not used anymore. VCSEL light sources are used and these sources will cause the light to travel with the lower order modes. These lower order modes are hardly influenced by bending the fibers. So the bend sensitivity of multimode fibers strongly depend on the launch conditions of the light source.
