Fibre Optic Cabling
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.
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
Couplers: LC - LC
Armoured cables such as CST (corrugated steel tube), SWA (steel wire armoured), or non-metallic (nylon-armoured) rodent-resistant cables can be used where physical damage is a risk or cables are buried directly or in underground ducts.
This information is very important when purchasing patch cable to connect from the DataCat patch panel to your switch. The patch cable must be the same ie 50/125 as the installed backbone cable. If your switch has different connection however (eg ST or LC) patch leads can be purchased with the appropriate connector at each end.
Multimode OM3 can be used to transmit data up to distances of 300m at 10Gb, while OM4 supports 100Gb 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.
