Wavelength Division Multiplexers
Wavelength Division Multiplexer (WDM) systems are popular with
telecommunications companies and some pitch control manufacturers. WDMs allow these companies to expand the capacity of the network without laying more fibre. By using WDM and optical amplifiers, they can accommodate several generations of technology development in their optical infrastructure without having to overhaul the backbone network. Capacity of a given link can be expanded by simply upgrading the multiplexers and demultiplexers at each end.
This is often done by using optical-to-electrical-to-optical (O/E/O) translation at the very edge of the transport network, thus permitting interoperation with existing equipment with optical interfaces.
Most WDM systems operate on single-mode fibre optical cables, whereas Optilinc is designed to operate on both single and multi-mode.
Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fibre is in limited supply or expensive to provision. As well as conventional dual strand fibre converters, with separate receive and transmit ports, there are also single strand fibre converters, that can extend full-duplex data transmission up to 70 kilometres over one optical fibre.
