Opnext demos 100Gb/s CFP and launches 40Gb/s modules

At the 35th European Conference and Exhibition on Optical Communication (ECOC 2009) in Vienna, Austria, optical component, module and subsystem maker Opnext Inc of Fremont, CA, USA announced two new additions to its 40Gb/s product portfolio in response to customer demand for longer-reach and smaller-size 40Gb/s solutions: DQPSK (differential quadrature phase shift keying) modules for dense wavelength division multiplexing (DWDM) transmission and compact VSR (very short reach) modules for client applications.

DQPSK technology offers enhanced performance with improved optical signal-to-noise ration (OSNR) characteristics and 50GHz channel spacing. Opnext claims that its DQPSK technology offers improved performance, simplified network design and lower manufacturing cost to network equipment manufacturers.

The new 40Gb/s VSR-2000-3R2 300-pin MSA (multi-source agreement) transceiver introduces a compact size and reduced power dissipation to the firm's 40Gb/s module portfolio. The SFF (small form factor) optical module has a 3.5-inch x 4.5-inch footprint. System applications are migrating toward higher-density 40Gb/s platforms, which require the smaller size and lower power that the 40Gb/s SFF solution can provide, says the firm.

At ECOC 2009, Opnext is also showcasing its CFP MSA-compliant module for 100GBASE-LR4 in a live demonstration. The CFP MSA defines the form factor of a hot-swappable optical transceiver supporting 40 Gigabit and 100 Gigabit Ethernet (GbE) and uses an transceiver electrical interface consisting of multiple 10Gb/s lanes. The 100GbE CFP optical module demonstrated at ECOC transmits and receives via four parallel wavelengths at 25Gb/s each, as per the IEEE 802.3ba 100GbE project.

“Network equipment vendors are introducing higher-bandwidth switching and routing solutions, flexible DWDM platforms, with extended-reach requirements and more challenging thermal environments,” says Tadayuki Kanno, president of Opnext’s module business unit. “Opnext’s 100GbE CFP, new 40G solution DQPSK MSA module and 40Gb/s SFF VSR deliver the cost and power savings necessary to meet next-generation network requirements,” he adds.
