FAQ related to Optical Fibers
Frequently Asked Questions
The frequently asked questions for optical fibers are as follows.
Is there any limit to the degree of bend in an optical fiber?
The minimum allowable bend radius of optical fibers is generally 30 mm. Therefore, bending an optical fiber to a radius of less than 30 mm should be avoided. Sumitomo Electric offers bend insensitive fiber products such as PureBand™-Plus, PureBand™-R, PureBand™-R[LL], and PureAccess™, which have a minimum allowable bend radius of 10 mm. Additionally, Sumitomo Electric has developed a 7.5 mm bend-radius SM fiber called PureAccess™[A2], which represents an even smaller bend radius.
What is the proper way to transport and store the fiber bobbins ?
Please refer the following illustrations.
Are the Sumitomo Electric optical fiber products compliant with EU’s RoHS Directive?
Yes. If you are considering exporting our optical fibers or some products incorporating those fibers to EU countries, you can download the RoHS certificate of conformity for the fibers from following link.
If you would like to request RoHS certificate for other products or materials besides the fibers, or other certificate besides RoHS, please contact our representative directly by clicking [Contact us] button below this page.
Can I use my fusion splicer for PureAdvance™ ?
Yes. PureAdvance™ series fibers can be spliced with standard fusion splicers. In addition, results can be further optimized if your splicer offers a G.654.E splicing program.
