Fiber optic cables used in telecommunication are broadly categorized in two types – Multimode fiber and Single mode fiber cables. Multimode fiber cable is prefixed with 'OM' and Single mode fiber cable is prefixed with 'OS'. In ISO/IEC 11801 and EIA/TIA standards four types of Multimode – OM1, OM2, OM3 & OM4 and two types of Single mode – OS1 & OS2 fibers are mentioned.

Microcables have been developed in purpose to utilize existing and new duct systems more effectively by accommodating more fibers in given sub-duct network. Another benefit is its light weight compared to conventional loose tube cables.

Fiber network architectures have evolved to a point that when coupled with specific optical components both active and passive and when used with customized transmission systems are now capable of providing cost effective FTTX service to customers requiring large quantities of bandwidth.

Network topology is the way various components of a network (like nodes, links, peripherals, etc) are arranged. Network topologies define the layout, virtual shape or structure of network, not only physically but also logically.
