Optical fibers


Loud & clear

After Corning had invented the low-loss fiber in 1970, this optimised optical fiber became the foundation for all major telecom networks and for the current Internet. The characteristics of these Optical fibers are the extremely fast transmission speeds, a safe, undisturbed connection that cannot be listened into and reduced costs compared to traditional copper cables. With Optical fibers, information can be transported over great distances, whether we are talking about telecom, data or video-files. Infraconcepts supplies Optical fibers for any size of project or network.


Optical fibers are available in various types for different kinds of networks, like backbone-, access- or company networks. All with the purpose of creating fast connections. These optical fibers are easy to link by using fusion splicing.
Signals are transported at high speed by means of laser light, and the transmission takes place at the wavelengths of 1310, 1550 and/or 1625 nanometre (nm) for the single-mode fibers, and for the multi-mode fibers at 850 and/or 1300 nanometre (nm). Single-mode fibers are used for data signal-transmission across substantial distances (e.g. FTTx, CATV, metro and access networks), and multi-mode for shorter distances (for example in enterprise networks).

You decide

When choosing a solution it is important, therefore, to consider not only the cable set-up, but also to select the right single-mode or multi-mode optical fiber.
Single-mode optical fibers have a core-diameter of 8-10 micron, which is covered in a cladding of 125 micron.

The most frequently used single-mode optical fibers:

  • Standard single-mode low water peak fiber
    (ITU-T G.652D), e.g. Corning SMF-28e® fiber family.
  • Full-spectrum bend-insensitive single-mode fiber with low/zero bend loss
    (ITU-T G.657A/B), e.g. Corning Clearcurve® LBL/ZBL fiber.
  • Full-spectrum bend-insensitive single-mode fiber with bend-optimisation and low-loss technology
    (ITU-T G652D & G.657A/B compatible), e.g. Corning® ULTRA® optical fibers.
  • Non-Zero Dispersion-Shifted single-mode fiber (NZDS),
    (ITU-T G.655D), e.g. Corning® LEAF® optical fiber.

Multi-mode optical fibers have a core-diameter of 50 micron or 62.5 micron, which is covered with a cladding of 125 micron.


The most frequently used multi-mode optical fibers:

  • Legacy multi-mode fiber (62.5 micron) for LAN-applications up to 1Gb/s
    (ISO/IEC 11801 OM1).
  • Bend-insensitive laser-optimised multi-mode fiber for use in enterprise networks
    (IEC 60793-2-10 A1a.1), e.g. Corning Clearcurve® OM2 fiber.
  • Bend-insensitive laser-optimized multi-mode fiber for high speeds of 10, 40, and 100Gb/s
    (IEC 60793-2-10 A1a.2), e.g. Corning Clearcurve® OM3 fiber.
  • Bend-insensitive laser-optimized multi-mode fiber for extra availability at high speeds
    (IEC 60793-2-10 A1a.3), e.g. Corning Clearcurve® OM4 fiber.


Your advantages

  • Fast: Faster data-transfer compared to copper cables.
  • Flexible: Flexible cable, lightweight and available in various compositions.
  • Reliable: Resistant to outside disturbances.
  • Secure: Optical fiber cables cannot be wiretapped like copper cables.
  • Competitive: Optical fiber is much cheaper than copper.
