Opnext launches next-gen 40G DPSK line-side module

At this week’s Optical Fiber Communication Conference and Exposition and the National Fiber Optic Engineers Conference (OFC/NFOEC 2011) in Los Angeles (8–10 March), optical module and component maker Opnext Inc of Fremont, CA, USA is launching its next-generation 40G differential phase-shift keying (DPSK) multi-source agreement (MSA) module.

The OTM-440S is a 300-pin module in a 3.5” x 4.5” small-form-factor mechanical package and is designed for metro, regional and long/ultra-long-haul optical transmission applications. Complementing the existing OTM-440 module (currently in volume production), it will be available starting in second-quarter 2011.

The OTM-440S is compatible with 50GHz reconfigurable optical add-drop multiplexer (ROADM) technologies and, combined with tunable dispersion compensators (TDCs), can be readily deployed in dense wavelength division multiplexing (DWDM) networks engineered for 10G non-return-to-zero (NRZ) modulation formats. With its smaller form factor and lower power consumption, the OTM-440S suits applications requiring high port density.

“We have invested in the next-generation DPSK module with a focus on reducing the form factor and power consumption,” says Mike Chan, president of Opnext’s subsystems business unit and executive VP, business development & marketing.

According to optical communications market research firm LightCounting, 40Gbps DPSK modules played a significant role in growing the DWDM market segment by more than 40% in 2010.
