Abstract

A 40-Gb/s optical module using WDM TOSAs for access network applications has been fabricated and demonstrated. This compact optical module was integrated by three thin-film WDM filters and four uncooled LX4 wavelength compatible DFB laser diodes. The output optical power was measured above -6 dBm with a clear 10-Gb/s transmission eye diagram. Due to the low dispersion characteristic of conventional single mode fiber at the LX4 wavelength, this module was expected to be able to transmit the signal up to 10 km and served as a cost-effective solution for 40-Gb/s transmission.
