The folks at Altera have announced SERDES Framer Interface Level 5 (SFI-5) standard support in their Stratix II GX FPGAs with embedded transceivers, providing a 40- to 50-Gbps interface for high-performance optical communications applications.
The SFI-5 specification is a chip-to-chip standard that ensures interoperability between forward-error correction (FEC) and the framer, as well as from industry-leading optical transponder devices. Hardware tested to verify compliance to the SFI-5 standard, Stratix II GX FPGAs feature up to 20 high-speed serial transceiver channels that can operate at data rates between 600 Mbps and 6.375 Gbps, easily satisfying SFI-5 interface requirements.
The SFI-5 Optical Internetworking Forum (OIF) specification was developed to provide an interface between the network processing devices and the optical transponder to enable higher bandwidths. The SFI-5 standard addresses network transport formats including OC-768, STM256, and OTN OTU-3.
In addition to supporting the SFI-5 standard, Altera Stratix II GX FPGAs are designed to deliver an extensive set of optical and electrical protocols with low power and industry-leading signal integrity, making them an ideal solution for use in all high-speed designs.
