Reflective optical amplifier targets WDM-PONs

Ipswich, Suffolk, United Kingdom—CIP is developing a reflective semiconductor optical amplifier (RSOA) that is designed to help implement advanced PONs (passive optical networks) based on wavelength division multiplexing (WDM).

Capable of delivering more than 20 dB of optical gain, CIP's RSOA provides optical data transmission at GbE rates without the need for either a local wavelength stabilized source or temperature control.

CIP is offering two versions of the RSOA: polarization sensitive or polarization insensitive. The polarized version is able to operate over a range of 0 to 70°C without the need for a temperature control device such as a Peltier cooler.

The polarization insensitive version's output characteristics include a gain ripple of 0.5 dB typical and a small signal gain of 20 dB typical over a wavelength range from 1530 to 1570 nm in the C band.

The RSOA is available in a TO-56 can package and fabricated using a InP (indium phosphide) process.
