Choosing Cable Construction

Cleerline SSF™ fiber is available in most of today’s most common cable constructions. SSF™ can be placed in typical industry configurations, whether smaller strand counts like Simplex or Duplex, high strand Micro Distribution types, or Armored and Direct Burial applications are required. Our cables are available in Riser, Plenum, LSZH, and PE type jacketing and in a variety of styles, allowing options for indoor, outdoor, and indoor/outdoor installation. Read on for more information on our specific cable constructions,

Micro Distribution

Cleerline Micro Distribution can replace all standard tight-buffer distribution cables. Unlike typical distribution cables, micro distribution cables do not utilize a 900um tight buffer layer within their construction. Micro distribution cable consists of one 2.0 or 3.0mm tube with a number of 250μm strands contained within it. This cabling is especially suited for indoor networking as it is lightweight, extremely flexible, and very fast to terminate.


Duplex cable is 3.0mm tubes,each containing a single strand of fiber, side by side in a zipcord-style construction. Duplex cable is frequently used for patch cords.


Simplex cable consists of one jacketed fiber optic strand in a 3.0mm tube. It provides the minimum number of strands possible for fiber installation.

Aluminium Interlocking Armored

Micro distribution AIA (Aluminum Interlocking Armored) fiber has a core protected by a spirally-wrapped aluminum strip. This cable is intended for indoor applications in which cable requires extra protection. Cleerline AIA cables are highly crush resistant and include a super-absorbent polymer to aid in water-blocking.

Corrugated Armored Steel Distribution (Direct Burial)

Corrugated Armored Steel Distribution cable is a loose tube construction, with an outer cable diameter of 9.0mm and a sub unit of 3.0mm. The core of the fiber is protected by a corrugate armored steel tube, and the fiber’s outer jacket is polyethylene. Direct burial cable is UV and rodent-resistant, as well as having superior crush resistance.

Breakout Cable

Breakout cable has an overall jacket with, typically, 2.0mm sub units/tubes, each with a single strand of fiber. Some constructions also include a central strength member. Breakout cable is extremely strong, with high crush resistance, as its construction provides extra protection for the glass. Breakout cable is also very efficient to terminate.

Micro Distribution, Duplex, and Breakout, are the three most prominent cable constructions.

Example Case: Choosing between Micro Distribution, Breakout, and Duplex cable styles.

Example: We will use a cable length of 125ft, labor rate of $80/hr, terminating with SC connectors in a 4-port keystone plate.

  • 2 separate duplex cables: (OM3 plenum rated)
  • Cable: $0.47ft per cable (qty. required: 2); total cost of fiber: 125ft x $0.47 x (2) = $117.50
  • Labor: (pulling cable) 30 minutes = $40.00
  • Connectors: (4ea) SSF-SC connectors $7.90ea = $31.60
  • Labor: (termination) 30 minutes = $40.00

Total duplex option terminated = $229.10

4 Strand Micro-Distribution:
    1ea 4 strand cable: (OM3 plenum rated)

  • Cable: $0.65ft per cable (qty. required: 1); total cost of fiber: 125ft x $0.65 = $81.25
  • Labor: (pulling cable) 30 minutes = $40.00
  • Connectors: (4ea) SSF-SC connectors $7.90ea = $31.60
  • Labor: (termination) 40 minutes = $53.20

Total micro-distribution option terminated = $206.05

4 Strand Breakout:
  • 1ea 4 strand breakout cable: (OM3 plenum rated)
  • Cable: $1.28ft per cable (qty. required 1); total cost of fiber: 125ft x $1.28 = $160.00
  • Labor: (pulling cable) 30 minutes = $40.00
  • Connectors: (4ea) SSF-SC connectors $7.90ea = $31.60
  • Labor: (termination) 40 minutes = $53.20

Total breakout option terminated = $284.80
