Things You Need To Know When Buying Fibre Optic Cable

One of the biggest decisions to make when buying Fibre Optic Cable is the type of Cable that is needed to meet the performance requirements of the application. Fibre Optic Cable can be used in many area’s such as LANs, data centres, wind farms, telecommunications etc.


So, what do we look for when choosing Fibre Optic Cables?Fibre Optic Cable


The Fibre Cable decision that is made at this stage will need to suit the performance requirements of the project so careful consideration needs to be taken.


The first question is “should we select to use Multimode or Single mode fibre”? This is important to know because the two modes are not compatible with each other, unless you use a media converter to convert the signal which can add extra unwanted costs.


The decision is easy if Singlemode cable is chosen. The only question left here is if it is an Indoor or Outdoor application?


Indoor/Outdoor Fibre Optic cable uses a dry-block technology and is of tight buffered design. Outdoor fibre optic cable uses internal dry water blocking technology to prevent water migration in the event of a breach in the sheath.


However, we are offered several varieties for Multimode cable. OM1, OM3, OM4 and OM5. The Fibre Cable chosen here will dictate speed, bandwidth and distance so the correct choice needs to be made to match to the hardware being used at the time!


Again, once you decide which Multimode Fibre Optic Cable suits your application you will need to decide if it is an Indoor or Outdoor Fibre Cable.


Once you have chosen the correct fibre type you will need to ensure you have the correct Jacket type. Some of the different cable options available are:

- (PVC) Polyvinyl Chloride Cable

- (LSZH) Low Smoke Zero Halogen Cable

- Nylon Jacket Cable for termite protection – you can request a sacrificial sheath as well to protect the cable when installing

- Armored Cable for rodent protection

- (GRP) Glass reinforced Plastic Cable

- (ADSS) All-Dielectric self-supporting cable


Then you are left with the next question of how many fibres you should include in your fibre optic cable? Typical core counts are 6 core – 12 core – 24 core, however the worlds highest density fibre count is 1728 fibres which was deployed here in Australia.


Last but not least is the length required to complete the installation!
