The Ultimate Guide to Fiber Optic Cable Types in 2024

Fiber optic cables are vital additives of cutting-edge telecommunications networks, offering excessive-speed information. It transmission over long distances with minimal sign loss. There are several forms of fiber optic cables, every designed for unique applications & environments. Below, we discover the unique fiber optic cable kinds and their characteristics:

Single-Mode Fiber (SMF):

  • Description: Single-mode fiber optic cables have a small core diameter (typically 9 microns) . It transmit data using a single light mode. They are primarily used for long-distance transmissions over vast distances.
  • Characteristics: SMF offers high bandwidth and low signal attenuation. It is commonly deployed in long-haul telecommunications, cable television (CATV), and internet backbone networks.

Single-mode fiber (SMF) Types:

  1. Standard Single-Mode Fiber (G.652): This is the most commonly used type of single-mode fiber. It offers low attenuation and is optimized for long-distance transmissions in telecommunications networks.
  2. Low Water Peak Single-Mode Fiber (G.652.D): This type of single-mode f minimize water absorption in the optical spectrum, improving performance in the 1260-1360 nm range.
  3. Dispersion-Shifted Single-Mode Fiber (G.653): Dispersion-shifted fibers are reduce chromatic dispersion, allowing for higher data transmission rates over longer distances.
  4. Non-Zero Dispersion-Shifted Single-Mode Fiber (G.655): This type of fiber is compensate for the nonlinear effects of dispersion.
  5. Non-Zero Dispersion-Shifted Fiber with Reduced Slope (G.656): This subtype of single-mode fiber combines the benefits of G.653 and G.655 fibers, offering improved performance and compatibility with existing networks.
  6. Bend-Insensitive Single-Mode Fiber: These fibers are minimize signal loss caused by bending or twisting.
  1. Multi-Mode Fiber (MMF):

  • Description: These types of cables have a larger core diameter (typically 50 or 62.5 microns) & support multiple light modes. They are used for shorter-distance transmissions within buildings, campuses, and local area networks (LANs).
  • Characteristics: MMF is suitable for shorter transmission distances and offers lower bandwidth and higher signal attenuation. It is commonly deployed in LANs, data centers.

Multi-Mode Fiber (MMF) Types

  • Step-Index Multi-Mode Fiber: This is the oldest type of multi-mode fiber, characterized by a core with a uniform refractive index. It is suitable for short-distance transmissions in LANs and premises cabling.
  • Graded-Index Multi-Mode Fiber (GI-MMF): GI-MMF features a core with a varying refractive index, allowing for better dispersion management and higher bandwidth over longer distances.
  • OM1 (62.5/125 µm) Multi-Mode Fiber: OM1 fibers have a core diameter of 62.5 microns and a cladding diameter of 125 microns. They are commonly used for legacy applications and short-distance transmissions.
  • OM2 (50/125 µm) Multi-Mode Fiber: OM2 fibers have a core diameter of 50 microns and a cladding diameter of 125 microns. They offer higher bandwidth than OM1 fibers and are suitable for longer-distance transmissions.
  • OM3 (50/125 µm) and OM4 (50/125 µm) Multi-Mode Fiber: These fibers are optimized for high-speed data transmission using vertical-cavity surface-emitting lasers (VCSELs) at wavelengths of 850 nm and 1300 nm. OM4 fibers offer higher bandwidth and longer reach than OM3 fibers.
  • OM5 (Wideband Multi-Mode Fiber): OM5 fibers are designed to support multiple wavelengths, allowing for increased data transmission capacity and flexibility in multi-mode fiber systems.
  1. Plenum vs. Riser Fiber Cables:

  • Description: Plenum and riser fiber optic cables differ in their jacket materials and suitable for different installation environments.
  • Characteristics: Plenum cables feature fire-resistant jackets that produce less smoke and toxic gases in the event of a fire.
  1. Armored Fiber Optic Cables:

  • Description: Armored fiber optic cables are reinforced with a protective layer, typically made of metal or polymer. They are used in harsh environments where cables may be exposed to mechanical stress.
  • Characteristics: Armored cables offer enhanced protection against external factors such as crushing, bending, and abrasion. They are commonly used in outdoor installations, underground conduits, and industrial facilities.
  1. Tight-Buffered vs. Loose-Tube Fiber Cables:

  • Description: Tight-buffered and loose-tube fiber optic cables differ in their construction and protection of individual optical fibers. Tight-buffered cables have a protective buffer directly applied to each fiber while loose-tube cables house fibers within a central tube surrounded by a gel or water-blocking material.
  • Characteristics: Tight-buffered cables are more suitable for indoor and patch cord applications due to their robust construction and ease of termination. Loose-tube cables offer better protection against moisture.
