Altera says it has demonstrated interoperability with a 100Gbit/s optical module using 28nm FPGAs in its Stratix V GT family.
The demonstration, at the Optical Fiber Conference (OFC) in Los Angeles next month, includes four channels of PRBS31 data generating within the Altera’s Stratix V FPGA.
The data is then transmitted over a Gennum VSR host channel with 12dB of insertion loss, through a Molex zQSFP+ connector to Gennum clock and data recovery (CDR) integrated circuits.
The retimed outputs of the CDRs are transmitted to the Molex 1490-nm Optical Module, which loops the optical data back to its receiver through 2 km of SM fibre.
The FPGAs are designed to support 25- to 28Gbit/s data streams for next-generation 100Gbit/s pluggable fibre optic modules, line cards and direct-attach copper cables using the 25G-QSFP+ and CFP2 form factors.
