Opnext’s QSFP+ 40GBASE-LR4 transceiver enters volume production

Optical subsystem, module and component maker Opnext Inc of Fremont, CA, USA has announced the production release of its QSFP+ 40GBASE-LR4 transceiver.

The firm says that, as industry leaders start to outgrow the reach and efficiency of current-generation 40GbE pluggables, the QSFP+ 40GBASE-LR4 transceiver offers the latest technology to those eager to scale up.

“QSFP+ is emerging as the standard for 40GbE,” says Rich Zoccolillo, president of Opnext’s pluggables business unit. “Adding the QSFP+ 40GBASE-LR4 product offering to our portfolio enables substantially higher port density and significantly lower power consumption,” he claims. “With the QSFP+ 40GBASE-LR4 transceiver, Opnext is introducing a low-cost integration and packaging technology for multiple long-reach DFB [distributed feedback] lasers—all inside a module no larger than a pack of gum.”

As OEMs are approaching the limits of current 40GbE technology in their data-center and enterprise applications, Opnext claims that its QSFP+ 40GBASE-LR4 transceiver can offer up to 100 times the reach of current QSFP+ SR4 solutions while improving on industry metrics compared to the CFP form factor — power consumption is reduced by more than 50% and almost 80% less faceplate surface area is occupied.

The evolution of laser integration technology allows for higher-density TOSA (transmission optical sub-assembly) packages. Combined with the maturation of the 40GbE supply chain, these packages enable more compact, better-performing, and more affordable 40GbE solutions, the firm claims. Opnext is now in full production with the QSFP+ 40GBASE-LR4 transceiver.

Opnext is exhibiting in booth #1425 at the Optical Fiber Communication Conference and Exhibition/National Fiber Optic Engineers Conference (OFC/NFOEC 2012) in Los Angeles (6-8 March).
