Single-mode and multi-mode fibre
|Single-mode fibres are meant for long distance data transmission networks (100 kms and above) due to their enormous bandwidth and low losses. They are generally used by telcos, CATV companies, railways, power grids and oil and gas companies. Multi-mode fibres are typically meant for short distances (maximum 2 kms) and are generally used in data and audio/video applications in local area networks.
|Large ﬁbre counts with small cable diameter. These cables are highly adaptable to mass splicing and are suitable for installation in pipelines.

|APAR offers single-mode optical fibre cables using G652D/G655 & G 657 fibres from 2F to 512 F, in armoured, unarmoured and aerial appliications. Multi-mode optical fibre cables using OM1/OM2/OM3 & OM4 fibres from 2F to 24F, in armoured, unarmoured and aerial applications.
|Single-mode fibre optic transmissions are faster than multi mode over long distances, because fewer switches or routers are needed mid span. They have virtually unlimited bandwidth, and are capable of transmitting data at up to 40 GB over hundreds of kilometers, with little integrity loss. Multi-mode cables are less expensive to install, operate, and maintain. Multi-mode cables have high speed and high bandwidth over short distances. They allow several mode optical signals to be transmitted at once.
