Why Cleerline SSF™ Fiber?

At Cleerline Technology Group, we know all the potential pitfalls to fiber optic installation. Traditional fiber can be fragile, difficult to install, and require extensive training.

With Cleerline SSF™, we’ve changed all that. Our innovative fiber optic cable is Stronger, Safer, and Faster to terminate than any comparable product on the market.

Stronger

Cleerline SSF™ has a proprietary Glass, Glass, Polymer construction. SSF™ coating provides an extra layer of strength to our glass, giving our fiber up to 10,000 times the bend capacity and up to 200 times the durability over traditional fiber.

SSF™ fiber has a minuscule minimum bend radius: as low as 3 mm during installation (depending on fiber type). Compare this to the industry standard 7.5 mm minimum bend radius for typical multimode bend insensitive fibers. No need to worry about SSF™ in a high-density rack installation.

Safer

SSF™ fiber provides greater safety for installers. SSF™ coating prevents glass shards from puncturing skin, protecting the technician. Our polymer coating remains present on the glass at all times, helping prevent contamination or damage to the glass. As shown in the traditional fiber cross section above, traditional fiber lacks any protective coating directly on the glass. This means that the glass is fragile and can easily shatter, creating hazardous microscopic shards.

Faster

Cleerline SSF™ does not require certification to terminate. Training can be as simple as watching a 4 minute instructional video. No scheduling commitment required.

SSF™ is also faster to terminate than typical fiber. In one case study, fiber technicians were able to terminate SSF™ up to 33% faster than other industry bend insensitive fiber. This translates into major savings in installation time.


How SSF™ Compares

SSF Termination time

SSF™ Fiber is far simpler to terminate because the bare fiber is never exposed, and SSF™ soft peel coating is far easier to remove than traditional fiber’s hard acrylate layer. In our 2014 case study, certified fiber technicians trained to work with traditional fiber were able to terminate SSF™ in an average time of 106 seconds.

Loss

That’s after only 10 minutes of instruction on how to work with SSF™. Comparatively, traditional fiber took an average of 159 seconds to terminate, or 33% longer. We’re confident that after more opportunities to work with SSF™, termination times would decrease even further. The case study also showed that after minimal training, technicians were able to achieve nearly identical attenuation rates with SSF™. Loss measurements for SSF™ were within 0.03 decibels (dB) of the loss measurements for traditional fiber when tested via single and double ended testing (fig. 2).

Hot Water Bend Test

Not only is SSF™ simpler to terminate, it is extremely resilient under difficult conditions. In one test, both SSF™ and traditional fibers were bent to a radius of 3 to 3.5 mm between two metal plates and submerged in 90°C water to simulate extreme conditions.

As demonstrated in the Figure 3, SSF™ took nearly 40 hours (130,000 seconds) to reach a 100% chance of failure. The nearest competitor took only approximately 16 minutes to reach a 100% failure rate.

SSF™ can tolerate a great deal of stress with little chance of failure, meaning enhanced security for installations. Furthermore, under the IEC60793-1-33 standard for fiber optics, fiber is tested to determine the dynamic and static fatigue values for the fiber, indicating how well fiber will last over time.

Dynamic Fatigue

Currently, demonstrating a dynamic fatigue value (n) of 18 is recommended for industry fiber. Under testing, SSF™ shows a dynamic fatigue value of n=30 (fig. 4).

According to the ITU-T Series G recommendations for fiber reliability, a higher n value indicates higher tolerance to strain. As demonstrated in the graph (fig.4), n=30 fibers like SSF™ are able to tolerate smaller bend radii under tension for a longer a period of time. The bottom line? The enhanced strength of Cleerline SSF™ means that installations will be built to last.
