Oclaro was in news recently when it that it will be previewing its latest high-speed optical network components and solutions at private customer suites (booth #2156 and 2160) during the OFC/NFOEC show in Los Angeles next week.

Oclaro has established a clear leadership position in 40G high bit-rate products and the company is well positioned to become the leading supplier for 100G deployments along with its existing portfolio of components and modules. Oclaro will continue to deliver products for all 40G modulation formats and will provide customers the flexibility of purchasing complete transponder solutions or individual components.

Oclaro is also planning to offer a new coherent receiver and 40G PM-QPSK modulator as sample in order to enable customers build their own coherent-based transponders or line cards for delivering higher performance and longer reach in the fiber optic network. Generally, there are three dominant 40G modulation formats generally used in networks today: DPSK (Differential Phase-Shift Keying), DQPSK (Differential Quadrature Phase-Shift Keying), and PM-QPSK (Polarization-Multiplexed Quadrature Phase-Shift Keying). Today, Oclaro is the volume shipment leader in 40G DPSK line side 300-pin transponders and is now the first company to deliver a coherent transponder solution incorporating the MUX, A/D and DSP functions in a single ASIC chip developed in partnership with ClariPhy Communications, Inc. 

In a press release, Andy Carter, chief technology officer at Oclaro, said, “The explosive growth of the Internet is driving an insatiable 'need for speed' in the core network – and this is where Oclaro is focused. This third generation of 40G coherent solutions will allow service providers to deploy highly scalable and flexible future-proof architectures and this is just the next step towards delivering the 100G speeds that will be required in the future.”

, a tier-one provider of optical communications and laser solutions, has its third generation 40G PM-QPSK transponder, the MI 5000XM. The solution features an integrated modulator, receiver and the industry's first single-chip ASIC solution for enabling coherent detection.
