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

In this letter, 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-/spl mu/m 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.

Demonstration of a compact low-power 250-Gb/s parallel-WDM optical interconnect

In this letter, we demonstrate error-free operation of a 12-fiber /spl times/4-wavelength /spl times/5.21-Gb/s parallel-wavelength-division-multiplexed (PWDM) optical link. The 250-Gb/s transmitter and receiver assemblies each have a 5/spl times/8-mm footprint and consume a combined power of 1.5 W. To our knowledge, this is the first publication of a fully functional PWDM optical interconnect as well as the highest demonstrated bandwidth per unit area and bandwidth per unit power consumption for any multiple-channel fiber-optic interconnect. This technology is intended for short-distance high-bandwidth-density applications such as multiprocessor computer backplanes.

Parallel-WDM for multi-Tb/s optical interconnects

This article presents a promising approach for multi-Tb/s optical interconnects. This approach is contained in the MAUI project, which develops a parallel multiwavelength optical subassembly (PMOSA) that uses PWDM to gain the component-density advantages of two-dimensional parallel optics and the connector and cabling density advantages of CWDM. In the MAUI approach, a standard multimode 12-fiber ribbon is used with 4 wavelengths transmitted through each fiber, for a total of 48 optical channels.

Ultra-compact, 0.5-Tb/s parallel-WDM optical interconnect

We discuss a 12-fiber /spl times/ 4-wavelength /spl times/ 10.4-Gbit/s short-distance parallel-wavelength-division-multiplexed optical interconnect. The 0.5-Tbit/s transmitter and receiver assemblies each have a 5 /spl times/ 8-mm footprint and together consume 2.95 W.
