SFP cable, also known as 10G SFP+ cable, SFP+ DAC twinax cable or SFP+ AOC cable, is a form of high speed cable with Small Form Factor Pluggable Plus on either end. The small form-factor pluggable (SFP) is a compact, hot pluggable optical module transceivers used for both telecommunication   and data communication applications. Direct-attach SFP+ cables provide a cost-effective, low-power alternative to optical SFP+ systems. Perfect for short-distance connections within racks and across adjacent racks, our direct-attach cables are available in both SFP+ passive copper and SFP+ active copper configurations.

As 10G network is widely deployed in today’s data center, SFP+ is the latest pluggable optical module form factor for use in 10-Gbit/sec Ethernet and 8.5-Gbit/sec Fibre Channel systems. The objectives of this new form factor are to increase density through its smaller footprint and provide a low-cost module to help enable increased adoption.The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ also introduces  direct attach for connecting two SFP+ ports without dedicated transceivers. Direct attach cables (DAC) exist in passive (up to 7 m), active (up to 15 m), and active optical (AOC, up to 100 m) variants.SFP+ is the 10-Gbps mainstream and current very high volume version of this interconnect family. Besides being specified in the 10 G Ethernet IEEE-802.3ak, this connector has been chosen for 14 Gbps InfiniBand and 16 Gbps FibreChannel.

Note

SFP copper cables are usually constructed using two individually shielded twin-axial transmission elements within an outer shielding layer for controlling EMI and achieving EMC regulations. SFP28 is the new 25-32 Gbps version.

Conclusion

With the convenience of plug and play technology, tarluz SFP of 10G  cable delivers throughput that exceeds those of industry standards. Besides, they also offer a variety of high speed interconnect DAC assemblies including 40G/56G QSFP + cable  and 100G QSFP28 cables to satisfy the demands from 10G to 100G interconnection. All of direct attach copper cables can meet the ever growing need to cost-effectively deliver more bandwidth, and can be customized to meet different requirements.
