25G Expansion in Networks and Servers

Supporting Network Architecture for Next Gen Data Speeds

As organizations push more traffic into their enterprise and private data centers, more bandwidth is required to move the data down into the fabric or top of rack. ToR architectures utilizing 10GbE to the server have the largest number of connections in data centers today, but these architectures are rapidly outgrowing 10GbE capabilities.

Benefits of 25G SFP28

Logical Upgrade Paths for Server Connections

SSFP+ is designed to operate at 10.3125 Gb/s whereas SFP28 is designed to operate at 25.78125 Gb/s. SFP28 utilizes the same familiar form factor as SFP+, so new systems will be able to scale from 10Gb/s to 25Gb/s using the same ports. Other benefits to SFP28 modules include increased bandwidth, superior impedance control, and less crosstalk than a SFP+ solution. As the technology becomes more prevalent the price of 25G modules will begin to match that of 10G.

The SFP28 provides a new optimized path for server connections: 10G – 25G – 100G. 25G hierarchy also implements into 50G & 100GBASE interoperability, making it a backbone in newer systems today. Since 25G offers a more efficient use of hardware and a more logical upgrade path to 100G, many companies like Cisco, Microsoft and Intel have put it into practice rapidly.

Cost Effective Cabling Choices

25G SFP28 takes existing module form factors, such as SFP28 and QSFP28, and allows for a breakout connection that is configurable as either 25G per lane or the full 100G without changing the port on the front of switch. QSFP28 to SFP28 breakout cable provides various cabling choices for switches and servers. For example, a 100G QSFP28 to SFP28 breakout cable can be configured to a 4x 25G server or a 2x 50G server connection. A QSFP28 to SFP28 breakout cable is a cost-effective solution for high density, high speed I/O data center applications.

Market Forecast Shows Exponential Growth for 25/50/100GBase Infrastructure

The Ethernet industry continues to innovate and lay a path to higher networking speeds like 100GbE. The 25GbE standard has been developed to provide a simpler path to future Ethernet speeds of 50 Gbps, 100 Gbps and beyond. These implementations capitalize on the 25GbE specification adopted by the 25 Gigabit Ethernet Consortium. The specification makes use of single-lane 25 Gbps Ethernet links and is based on the IEEE 100GbE standard (802.3bj).

Considering the significant benefits and compelling economics of 25G, it is no surprise that the move from 10G and 40G to 25GbE is accelerating. The advent of 25G changes the connection speed of servers and the migration path to 50G or 100G (and beyond), which in turn accelerate the development of 25G. 25G SFP28 assemblies, as an important bridge in this progress, are booming now and Will continue to into the future.
