have announced their plans for a joint demonstration of interworking the world's first 40G coherent transponder module from CoreOptics and EXFO's FTB-8140 Transport Blazer test module at OFC/NFOEC 2010.
The demo is built around Juniper Networks' PTX Series Packet Transport Routers, including their integrated 100G coherent transponder and ADVA Optical Networking's 100G Core technology, and firmly underlies the strong interoperability and shared vision of the three parties.
The new Oclaro transceiver is based on a direct-detection ODB (Optical Duobinary) modulation format which complements Oclaro's line of 100G coherent transponder solutions.
NASDAQ: OCLR), a tier-one provider and innovator of optical communications and laser solutions, today announced that it has further strengthened its coherent product portfolio with the introduction of the MI 8000XM, a high-performing, low-power 100 Gbps MSA-compliant coherent transponder module.
Oclaro's achievement of volume shipments for its 40G coherent transponder based on our LightSpeed CL4010 SoC is a testament to our successful partnership.
It ensures integration of critical features, such as mapping and multiplexing of a wide range of protocols, while leveraging MSA-compliant merchant 40G coherent transponder modules for the best performance and lowest cost.
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.
