SFP+ (Small Form-factor Pluggable)SFP+ (Small Form-factor Pluggable) Product Page

SFP+ (Small Form-factor Pluggable)

The TE SFP+ product family extends the use of the Small Form-factor Pluggable (SFP) interconnect up to 10 Gbps. This system meets the performance requirements of SFF (Small Form-factor) specification SFF-8431 and supports 8 G Fiber Channel, 10G Ethernet, InfiniBand™ standard and Fibre Channel over Ethernet (FCoE) applications. The SFP+ product family includes cable assemblies, cages and connectors.

The TE SFP+ direct-attach copper cable assemblies provide a cost-effective solution over fiber optics in short reach applications. The design allows for serial data transmission up to 10 Gbps in each direction. The mechanical design of the cable braid crimp and EMI skirt suppress EMI radiation. Low power consumption helps make the SFP+ copper cable assembly an economical solution for within rack or rack-to-rack applications. Both passive and active copper cable assemblies are available.

The passive cable assembly design has no signal amplification in the cable assembly. Electronic Dispersion Compensation (EDC) is typically used on host board designs when passive SFP+ copper assemblies are utilized. EDC allows for an extended length of passive cable assemblies. The industry-standard EEPROM signature enables the host system to differentiate between a passive copper cable and a fiber optic module.

The active cable assembly design has signal amplification and equalization in the assembly. Active copper assemblies are typically used in host systems that do not employ EDC. Active SFP+ cable assemblies also incorporate Rx LOS and Tx Disable features. As with passive cables, the industry-standard EEPROM signature enables the host system to differentiate between an active copper cable and a fiber optic module.

Key Features:

  • MSA SFF-8431
  • Supports serial data rates up to 10 Gbps
  • Low-cost alternative to fiber optic assemblies
  • Low power consumption
  • Enhanced EMI suppression
  • 24 AWG through 30 AWG cable available
  • Pull-to-release retractable pin latch design


  • Switches
  • Networking: servers, routers and hubs
  • Enterprise storage
  • Telecommunications equipment
  • Network Interface Cards (NIC's)
