AFCT-701SDDZ :10Gb/1Gb Ethernet, 1310nm SFP+ Transceiver The Avago AFCT-701SDDZ transceiver is part of a family of SFP+ products. This transceiver utilizes Avago’s 1310nm DFB and PIN Detector technology to provide an IEEE 10Gb Ethernet design compliant with the 10GBASELR standard and allows for the operation at 1.25GBd for Gigabit Ethernet Applications. The AFCT-701SDDZ transceiver has the signal and the chassis SFP grounds tied together to enhance the EMI shielding performance of the module, providing extra margin that is particularly useful in higher density applications. The design is based on the new electrical and mechanical specification enhancements to the well known SFP specifications developed by the SFF Committee. These specifications are referred to as SFP+ to recognize these enhancements to previous SFP specifications used for lower speed products.

Avago Technologies is an active participant in the SFF Committee specification development activities.
