SSF vs. BendSafe: Which Fiber Construction Should I Choose?

SSF vs. BendSafe: Which Fiber Construction Should I Choose?

Feb 27, 2026

Trying to choose between cables built with Cleerline SSF and Cleerline BendSafe? The below chart tackles common considerations when choosing a construction. 

 


Cleerline SSF Cleerline BendSafe
I am new to fiber.  SSF offers the easiest installation experience for technicians that are new to fiber. Its patented construction literally allows "hands-on" cable preparation without the worry of glass shards.   
I need the most cost-effective cable. 
Cables built with BendSafe tend to be lower priced than their SSF equivalents. 
I need the most durable cable.  SSF is much more durable than BendSafe -- in fact, it's one of the most durable options in the industry. SSF provides a 30% superior flex rating and impact rating over BendSafe. 
I am fusion splicing my connections.  SSF supports fusion splicing; however, you need to strip the polymer with a Tri-Hole Stripper. The process takes slightly longer than with BendSafe.  BendSafe provides a faster out-of-the-box fusion splicing experience -- the process is identical to traditional bend-insensitive cable. 
I am terminating my connections with mechanical connectors.  SSF provides a superior installation experience when using mechanical connectors. The process is easier and the overall termination loss is less thanks to SSF's more durable strand construction. 
I am pulling cable and have limited space in my conduit and pipe.  Cables built with SSF are up to 50% smaller in diameter than their BendSafe equivalents. SSF cables provide 250µm micro-distribution constructions without sacrificing strength and durability.  
I am installing fiber and have limited space in my enclosure and wall box.  Cables built with SSF support a 2.2mm bend radius compared to BendSafe's 3.0mm bend radius. They support coiling in my tighter spaces. 
My rack is crowded and I'm worried about heat dissipation.  Patch cords built with SSF support 1.2mm micro-diameter constructions without sacrificing strength and durability -- that's up to 60% more space for airflow in a crowded rack. 
My cable is outside and I'm worried about performance in hot and cold temperatures.  Cables built with SSF support a much wider temperature rating -- it's common to see cables rated for -75 to 158°F (depending on the cable construction, of course). 
My cable is in a wet location and I'm worried about cable degradation.  SSF provides much better protection against water and humidity -- two of the leading causes of micro-fracture cable degradation. SSF's patented polymer-coated construction keeps water and humidity away from the optical strand. 
I'm integrating my cable with fiber products from other manufacturers. Both SSF and BendSafe are compatible with leading fiber cabling, connectivity and cable management products.  Both SSF and BendSafe are compatible with leading fiber cabling, connectivity and cable management products.
