Opnext demos 40GBASE-LR4 QSFP+ transceiver module for 40GbE over 10km single-mode fiber

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 demonstrating its quad small-form-factor pluggable plus (QSFP+) transceiver module (which will enter production in second-half 2011).

Existing QSFP+ modules primarily support multimode applications (with a 100m limitation), making the single-mode QSFP+ the next logical addition. Opnext’s 40GBASE-LR4 QSFP+ module uses single-mode optics to transmit 40GbE traffic over a distance of 10km.

The 40GbE QSFP+ module extends Opnext’s existing 40G family of products, which includes the 40GBASE-LR4 module in the larger CFP form factor (which is seeing initial deployments in customer systems now and has just been announced as production released). 40GBASE-LR4 technology offers OEMs a lower-cost, longer-reach alternative to traditional 40G Sonet/SDH client interfaces and makes 40G deployments more economically viable in high-speed switches and edge routers, says Opnext.

The QSFP+ 40GBASE-LR4 transceiver module is the newest technology for OEM next-generation systems where industry leaders are eager to extend reach, increase speed and lower their customers' overall power consumption in support of large data-center and enterprise applications, says Opnext. Moving to 40GbE QSFP+ also significantly improves port density.

“As QSFP+ emerges as the standard for 40GbE, adapting the technology to longer-reach single-mode applications enables our customers to increase their network speed, realize higher port density and lower overall power consumption,” says Rich Zoccolillo, president of Opnext’s pluggables business unit. “With the QSFP+ 40GBASE-LR4 transceiver module, Opnext is building on its existing leadership in high-speed, single-mode transceivers and optical integration,” he adds.
