Normally, we need to choose a Fiber Optic Cable according different application and distance. People often ask how to choose the right Fiber Optic Cable. In order to choose the right Fiber Optic Cable, knowing how many Fiber Optic Cable Type there are and the characteristic of each Fiber Optic Cable are very importance.
Below is the list of Fiber Optic Cable Types:
- Multimode vs. Single-mode
- Simplex vs. duplex cables
- PVC (riser) vs. plenum-rated
- Distribution-style vs. breakout-style
- Loose-tube vs. tight-buffered
Multimode vs. Single-mode
Multimode cable has a large-diameter core. The most two commonly core sizes is 50-micron and 62.5-micron. Single-mode cable has a small (8–10-micron) glass core.
Multimode cable usually is orange or aqua jacket; single-mode is yellow jacket. Multimode fiber optic cable use for most general data and voice fiber applications. (Multimode 50-micron cable is a better choose for premise applications) Single-mode cable is usually used in high-bandwidth applications and in long-haul network connections.
Simplex vs. Duplex cables
Simplex has one fiber, while duplex has two fibers. As Simplex fiber optic cable only have one fiber link, it use for applications that only require one-way data transfer. Duplex (multimode or single-mode) fiber optic cable use for applications that require simultaneous, bidirectional data transfer.
PVC (riser) vs. Plenum-rated
PVC cable have an outer polyvinyl chloride jacket and will gives off toxic fumes when it burns. Plenum can replace PVC, but PVC cannot be used in plenum spaces.
“Riser-rated” is means fire-resistant. Plenum cables have FEP and emits less toxic fumes when it burns. In most office buildings, must be use Plenum cables.
Distribution-style vs. Breakout-style
Distribution-style cables are several tight-buffered fibers bundled under the same jacket and use Kevlar or fiberglass rod to reinforcement. Distribution-style cables are small. Usually use within a building for short, dry conduit runs, in either riser or plenum applications. Breakout-style cables is several simplex cables bundled together. Use for riser and plenum applications.
Loose-tube vs. Tight-buffered
loose-tube and tight-buffered cables are include strengthening member, like aramid yarn, stainless steel wire strands, or gel-filled sleeves. Loose-tube cable is the first choice for harsh, high-humidity environments. Tight-buffered cable is use for moderate-length LAN/WAN connections, or long indoor runs.
