Single Mode Fibre Cables: OS2/OS1

4Cabling is Australia's premier destination for single mode fibre cable solutions. Our single mode fibre cables are expertly designed for applications that demand long distance communication without compromising signal integrity. Thanks to their superior ability to maintain the purity of light pulses over extended stretches, single mode cable offers a more reliable and consistent connection for your critical networking needs.

4Cabling OS1 / OS2 cables are not just any cables; they are G652D OS2, fully compliant with the ITU-T recommendation G.652.D and IEC 60793-2-50 type B1.3 Optical Fibre Specification, underscoring our commitment to world-class manufacturing and stringent quality controls. 

Take a look at our extensive single mode cable inventory which includes a wide range of terminations such as LC-LC, LC-SC, LC-ST, SC-SC, and SC-ST. As well as our stocked single mode fibre cables, 4Cabling can also custom manufacture fibre cable to your specifications. Every lead we supply comes with a factory test report, guaranteeing that our fibre leads are completely immune to electromagnetic noise.

 What is a single mode fibre cable?

The single mode fibre (SMF) cable is predominately used for applications involving large distances (over 100km). With a small diametral core, in a single mode fibre optic cable only one ray or mode of light is able to propagate at a time. All the signals travel straight in the middle without distortion including modal dispersion, modal noise, and other effects that can occur with multimode transmission. As the light passes through the core decreases lowering attenuation, it also  allows the signal to travel further. Cable TV, telephone, and internet are some of the signals most often carried by a bundle of single mode fibre cables. Single mode fibre cables also provide a much higher bandwidth speeds, which you require for fast, reliable, and effective business IT infrastructure.  

What is the difference between single mode fibre and multimode fibre?

When it comes to single mode vs multimode,  single mode fibre optic cable:

  • Propagates a single light mode.
  • Has higher bandwidth.
  • Transmits data over greater distances
  • Allows higher volumes of data to be dispersed without interruption.
  • Single mode fibre cables are cheaper but require more expensive active equipment.

Multimode fibres:

  • Support simultaneous light modes.
  • Is fine for shorter distances.
  • Have higher attenuation (the loss of light between input and output) rates, which negatively affects the performance of the multimode optical fibre.
  • Utilise cheaper electronics, lowering overall system costs. 

 What does OS1, OS2, OM1, OM2, OM3, and OM4 mean?

Are fibre optic cable designations that originated in the international ISO/IEC 11801 standard and indicate a particular level of performance.

  • OS = have much thinner cores and are levels for single mode fibre.
  • OM = have cores over 100 microns and are levels for multimode fibre.
  • OS1 = uses LED transmitters, applies to standard single mode glass, is used for distances less than 2km (a tight buffer fibre for indoor usage), and hits transmission speeds of 10Gbps.
  • OS2 = is standard for long-range networking, uses LED transmitters, refers to higher performing low-water peak single mode glass, can carry signals up to 200km (a loose buffered fibre for outdoor usage), and achieves transmission rates over 10Gbps.
  • OM1 = comes in a orange jacket and has a standard 62.5 micron multimode glass core size; uses a LED light source; used in short-haul networks, LANS, and private networks.
  • OM2 = comes in a orange jacket and has a standard 50 micron multimode glass; is commonly used for 1 gigabit ethernet applications in short-haul networks, LANS, and private networks.  
  • OM3 = comes in an aqua jacket; is for enhanced 50 micron glass (10 gigabit ethernet out to 300m is most commonly used); is optimised for laser based equipment and can be applied to larger private networks.
  • OM4 =  comes in an aqua jacket; is completely backwards compatible with OM3 fibre; identifies enhanced 50 micron glass (10 gigabit ethernet out to 550m); was developed specifically for
  • VSCEL laser transmission; is more advanced and used for high-speed networks such as data centres, and financial and corporate organisations.

What are the benefits of a single mode fibre?

There are particular benefits that come with using a single mode fibre optic cable, including: 

  • Are faster over long distances because (uses fewer switches and routers).
  • Has better stability and is able to transmit data over hundreds of kilometres and fast speeds without drop-out.
  • Practically provides  unlimited bandwidth capacity.
  • Our single mode fibre leads are factory tested and immune to electromagnetic noise.
  • Can be used for long-distance telecommunication and decorative illumination.
  • Cables and connectors are less expensive compared to multimode fibres, and single mode cable is often more economical when purchased in bulk.

At 4Cabling, we are committed to providing you with industry-standard, high-quality single mode fibre cable and fibre patch panel products, so see for yourself why we are Australia’s most trusted supplier and distributor.
