Oclaro Inc of San Jose, CA, USA, which provides lasers and optical components, modules and subsystems for the optical communications, industrial, and consumer laser markets, says that the dual-rate 100G CFP2 LR4 transceiver (which is fully interoperable with the second-generation 100G CFP LR4 transceiver, supporting both OTU-4 and 100GbE interfaces) has joined that module in volume production.
About 30 customers have already qualified or are in the process of qualifying the 100G pluggable LR4 transceiver modules. The 100G MSA-compliant CFP2 LR4 module recently completed interoperability testing with the Xilinx Virtex-7 H580T FPGA for OTU-4 based on the OIF CEI-28G-VSR board interface specification. Both the CFP and CFP2 LR4 modules have now passed testing for both data rates.
Oclaro says that a fully interoperable pair of CFP and CFP2 LR4 transceivers offer network equipment manufacturers the flexibility to rapidly and easily capitalize on the smaller form factor and lower power consumption of the CFP2, while offering customers an upgrade path from deployed equipment with CFP cages to increase system front-panel bandwidth with higher module density and/or to lower system power consumption per 100G interface. As the CFP MSA standard continues its growth as the form factor of choice for adoption in many 100G enterprise and data-center applications, Oclaro reckons it is well positioned to help users lead this next phase of high-speed networking.
"Xilinx and Oclaro have successfully achieved interoperability between the Xilinx Virtex-7 H580T FPGA and the Oclaro 100G CFP2 LR4 optical module, showing an error-free connection at 28.0Gb/s," notes Gilles Garcia, director of Wired Communications at Xilinx. "Together with previously demonstrated interoperability at 25.7Gb/s, system OEMs designing transport, networking and data-center applications can now realize 100 Gigabit Ethernet and 100G OTL4.4 applications with lower cost and power, enabling either more efficient or higher-density network line-cards," he adds.
"We are delighted to see the interest from our customers for both our 100G CFP and CFP2 LR4 transceiver products. This confirms the value of our strategy to continuously work to reduce size and power while providing backward compatibility when possible to ease customer adoption," says Yoshikazu Era, general manager, Oclaro Japan Module Division.
The second-generation CFP and CFP2 transceivers are in volume production and available now.
