Fibre Optic Cabling Installation in London

Fibre Optic data cabling uses photons (units of light) to transmit data as opposed to electrical pulses. As a result, high speed and reduced data loss can be achieved over greater distances than with copper cable. There are two basic types of fibre optic – Single and Multimode. Single Mode is used when even greater distances are necessary – for example when connecting to the much-loved speed cameras that are a feature of our motorways or for WAN connections (eg by ISPs).

DataCat focus on Multimode fibre optic cabling which is more commonly used for vertical (backbone) cabling in single-site business, education and administration environments. Fibre optic cabling can seem very confusing, not least because a number of different standards of cable and connections have evolved over time.

DATACAT TYPICALLY INSTALL THE FOLLOWING:
  • Cable: Multimode Indoor/outdoor Tight Buffered LSOH OM3 or OM4 50/125
  • Connectors: LC
  • Couplers: LC – LC

Armoured cables such as SWA (steel wire armoured), or CST (corrugated steel tube) rodent-resistant cables can be used where physical damage is a risk or cables are buried directly or in underground ducts.

Loose tube Gel-filled) cable is recommended where there horizontal runs externally or in ducts.

Multimode OM3 can be used to transmit data up to distances of 300m at 10Gbps, while OM4 supports 10Gbps up to 600m and 100Gbps up to 150m. Cables can contain between 4 and 24 cores to provide multiple links or redundancy (each link constitutes a duplex connection and therefore requires 2 cores). Patch leads can be supplied on demand. We are always happy to advise clients on the most suitable standard to suit their requirements and budget.

At DataCat we employ our own skilled fibre optic technicians and use the latest generation of splicing (Sumitomo T-71) and testing (Psiber WX4500) testing equipment. As with copper installations, full test results are recorded and provided to the client in PDF form on completion.
