ec79od802a-LCIP announces its reflective semiconductor optical amplifier (RSOA) family which offers the performance to implement advanced PONs (passive optical networks) based on wavelength division multiplexing (WDM). Capable of delivering more than 20 dB of optical gain, this component provides optical data transmission at gigabit Ethernet rates without the need for either a local wavelength stabilized source or temperature control. This combination provides a platform for access network providers to boost performance. The RSOA device itself is monolithic, and it is made using a proven InP (indium phosphide) process that is well suited to high-yield volume manufacture. This RSOA component provides high-speed transmission capability for clients in WDM-PON networks by reflecting and modulating a 'seed' light that is transmitted throughout the network.
