Demonstration of a small-form-factor WWDM transceiver module for 10-Gb/s local area networks

We demonstrate for the first time all key components for a small-form-factor (SFF) wide-wavelength-division-multiplexed (WWDM) transceiver module with four channels operating at a data rate of 3.125 GBd/channel giving an aggregate rate of 12.5 GBd. The key components that enable a SFF package include a compact injection-molded plastic demultiplexer and a compact transmitter optical subassembly. We report link results showing successful operation of these key components with transmission over 300 m of 62.5-μm core multimode fiber (MMF) and 10.5 km of single-mode fiber (SMF). These technologies enable highly-integrated WWDM 10-Gb Ethernet transceiver modules that support both MMF and SMF.
