Abstract

In the last years, high quality silica optical fibers have been developed where a reduction in the OH content resulted in a transmission loss lower than 0.5 db/km at a wave length range of 1.3 µm. At M/A-COM LASER DIODE INC., edge emitting InGaAsP/InP double heterostructure LEDs have been developed for this wavelength range that are efficiently coupled to single and multimode optical fibers. Optical Fiber Communication systems employing 1.3 µm edge light emitting diodes (ELEDs) as transmitting sources offer advantages over lasers for both multi and single mode applications. Their reliability is higher, they are less sensitive to changes in temperature or variations of the drive current. Also, their driver circuits are simpler because they do not require optical power monitors. LEDs are not susceptible to external feedback. That is, small feedback signals from coupled fibers or from connectors within the fibers, will not induce any noise. This allows the ELEDs to be desirable sources in the competitive areas of local area networks (LANs), tele-communications systems and local loop distribution networks.
