SCFF Transceivers

AFCI’s SCFF optical transceivers TRX08GVP2540 for 2G/4G/8G FibreChannel applications & TRX10GVP2040 for 10G-Ethernet and Fibre Channel applications are built to a small cubic form factor (SCFF) that maintains compliance to the SFF-8431 interface standard while requiring 40% less PCB real estate vs. standard SFP+ transceiver systems. Its 11pin electrical connector supplies the electrical connection and a robust EMI cage encapsulates the entire assembly in order to assure proper EMI shielding compliance.

The assembly includes a 2 wire serial interface similar to I2C interface and power supply. It is RoHS 6/6 complaint per Directive 2002/95/EC and laser safety class 1 compliant per IEC/CDRH. The sub watt power consumption and the compact size enables hardware system designs with high port density.
