25G SFP28 Cable

Best for TOR Server Connection This standard was called 25 Gigabit Ethernet or 25Base-T, developed by IEEE 802-3 task force P802.3by. This standard was derived from the 100GB Ethernet Standard; however, its operation works as a single lane connection with 25Gbps that can be run on fibers or coppers.

The QSFP28 transceiver form factor was constructed in four parallel 25Gpbs data lanes allowing a maximum rate of 100Gbps, the SFP28 offers a single 25Gbps data lane. The physical structure of the 25G SFP28 transceiver is the same with the popular SFP and SFP+.

This characteristic provides a flexible solution due to the fact that 100 Gigabit can also be divided individually in to four 25Gbps connections.

SFP28 uses a 28Gbps lane (25Gbps + error correction) specifically used for top-of-rack (TOR) switch to server connectivity.

Direct Attach Cable and Active Optical Cable SFP28 Solutions The DAC copper cable version is manufactured in a single fixedconfiguration module which means the copper cables are directly attached to a 25G SFP28 transceiver module.

Benefits of 25G SFP28 Cable Connections

The development of 25G SFP28 connections has provided a wide range benefits especially in a web-scale data center environment where the trend goes towards a single port server due to the costs.

The reason for this is that, existing 100G port can be used as a 4x25G with as QSFP28 to SFP28 DAC or AOC break out cable instead of using for different ports. For example, a 25Gbe transceiver can provide 2.5 times more data than the popular 10G DAC / AOC SFP+ solution and can provide greater port density.
