Tribit’s FPGA-based networking dev board supports as many as 66 SFP, SFP+, and QSFP28 optical modules

 

Tribit, a small team of design experts in Russia, has developed a network switching platform called the A10_66SFP+ board that is based on one Intel® Arria® 10 GX FPGA. The Tribit networking platform uses the FPGA’s SerDes transceivers to drive as many as sixty-six 10 Gbps serial ports. Forty-eight of these ports connect to front-panel optical card cages. Of these 48 ports, forty-six ports terminate in SFP+ optical cages that accept 10 Gbps optical modules while the remaining two front-panel ports terminate in small form-factor pluggable (SFP) cages that accept 1 Gbps copper or optical modules. In addition to Ethernet, these ports can use the Intel-supplied physical coding sublayer (PCS) soft IP core to support many different network and I/O standards including 1Gigabit/s SFP, SDH/OTN, and PCIe.

The Tribit A10_66SFP+ board also accommodates two 32-bit DDR4 SDRAM modules and two FPGA Mezzanine Cards (FMC cards) for expansion. The FMC slots can support as many as twenty additional SFP+ optical cages or two 100 Gbps QSFP28 cages using a pair of 100 Gbps FMC gearbox/retimer modules.

 

The Tribit A10_66SFP+ board is designed to allow rapid development of network appliances

 

This board demonstrates the Intel Arria 10 GX FPGA’s versatility as a single-chip device, which can be used to develop many types of high-speed networking equipment. The Intel Arria 10 GX FPGA supports multiple high-speed serial ports, backed with a large amount of programmable logic and closely coupled, on-chip, fast SRAM. According to a blog posted on its Web site, Tribit employed an FPGA for this design because the FPGA-based design approach significantly reduces development costs and time to market while creating a versatile, flexible design that can support a variety of networking appliance designs. According to Tribit’s hardware-software development leader Mike Reznikov, his team selected the Intel Arria 10 FPGA because it was the best FPGA in its class, from the team’s perspective.
