Superlink(SLK)’s SFP+  Cable Assembly Overview:

The Superlink’s SFP+ copper cable assemblies extend the use of the Small Form-Factor Pluggable (SFP) interconnect up to 10G bps. This system meets the performance requirements of SFF (Small Form-Factor) specification SFF-8431 and supports 8G Fiber Channel, 10G Ethernet, InfiniBand™ standard and Fiber Channel over Ethernet (FCoE) applications. Superlink’s SFP+ copper cable assemblies provide a cost-effective solution over fiber optical cable assemblies in short reach applications. The design allows serial data transmission up to 10Gbps in each direction. The mechanical design of the cable braid crimp and EMI skirt suppress EMI radiation. In Superlink, both passive and active SFP+ 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 recognize a passive copper cable or 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 without EDC. Active SFP+ cable assemblies also incorporate Rx LOS and Tx Disable features.
