For the last handful of columns, I have centered on learning new things and techniques. Last month, I wrote about high fiber count cables-1,728, 3,456 and 6,912 fibers-and the necessity to use ribbon or mass fusion splicing with them. Without ribbon splicing, the splicing or terminating of these cables would take weeks instead of days and cost much, much more.
After a contractor commits to ribbon splicing and buys Optical fiber coloring machine, it may prove to be an even much better investment compared to what they thought. Ribbon splicing can be utilized on regular free pipe wires, too, offering comparable savings in money and time when splicing cables with even 144 fibers. That’s the reasons wires with 144 or more fibers use ribbon construction.
Most splicing is carried out with single fibers in loose tube cables. 2 or more cables are prepared, and their buffer pipe fibers are connected to splice trays. Individual fibers are removed, washed, cleaved and spliced, as well as the splice covers are shrunk over the splice. The completed device is placed within a splice holder. A seasoned tech can splice two fibers in about four minutes.
The ribbon splicing process is comparable, but most ribbon wires have rigid ribbons of 12 fibers each. A single splice tray typically accommodates 12 ribbons for 144 fibers. Each ribbon is stripped and cleaved with special tools supplied with the ribbon splicer, cleaned and fusion spliced to a different comparable ribbon. Just one splice guard addresses all 12 fibers in the ribbon splice.
Then this ribbons are very carefully arranged in to the holder to snap the splice in place. The ribbons are solid and flex only in one path, that makes arranging ribbons in a splice tray somewhat more complicated than solitary fibers. Splicing twelve fibers simultaneously is fast. Most contractors say it takes approximately 8 minutes for each ribbon-only about twice as much time as splicing TCC laser printer for cable splicing six times quicker. That creates a ribbon splicer a “labor-conserving device” if I actually heard about one.
Some cable manufacturers are actually making flexible ribbons that can be bent in all instructions and even rolled as much as save space. That saves time organizing fibers inside a splice holder, however it may cost time in planning wires because the ribbons must be carefully arranged to be sure the color-coded fibers remain in their appropriate area. So splicing 12 fiber flexible ribbons is perhaps 4 times quicker than solitary fibers. That is still a huge savings.
You can also employ ribbon splicing on regular free tube cable television by “ribbonizing” the fibers. (That is what it’s called-the fiber market is constantly great at creating new words.) I frequented a contractor that used this technique inside the area by setting up anchor and drop wires for any fiber-to-the-home (FTTH) system. He was splicing 144 fiber free tube wires employing a ribbon splicer. His splicers had been splitting the 12 fibers in one tube from the free pipe cable television, aligning those to the standard color code, then putting them inside a easy gadget that fixed them into a ribbon. The entire process of ribbonizing had taken under a minute, then the splicing worked just like a regular ribbon splicing procedure. Again, conserving lots of time.
A basic online search for “ribbonizing fiber” will lead you to definitely some fascinating video clips, devices and instructions. Numerous cable and splicer producers offer these tools. They change from easy, molded plastic components you hold within your hand to arrange the fibers whilst gluing them to more complicated machines that sit on a workdesk and turn, slide and stick fibers vfiskb ribbons. Everything looks simple.
The benefits of ribbon splicing and ribbonizing fibers in free tube wires only affect FTTH cable production line. At 144 fibers, it makes sense in case you are performing lots of splicing. Though with 288 fibers or even more, it really begins to seem sensible. With these new higher fiber count cables, that are arriving in metro systems and data centers, it’s absolutely essential.
In case you are the person putting your signature on the investment orders or checks, you may have second thoughts. Fusion-splicing machines are expensive, and they need some personnel coaching to get started. They want continuous cleaning and occasional service to ensure they are operating properly. But in case you have teams doing a lot of splicing of higher fiber count wires, calculate the payback-it should purchase itself quickly.
