They are compliant with SFF-84311, SFF-84322 and IEEE 802.3ae 10GBASE-LR/LW3. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-84724. The FTLX1471D3BCL is a “limiting module”, i.e., it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturer’s recommended settings for interoperating the host-board EDC PHY with a limiting receiver SFP+ module. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC5, and Finisar Application Note AN-20386. PRODUCT SELECTION FTLX1471D3BCL © Finisar Corporation - May 2008 Rev.

T is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on FAULT 3. 4. 5. the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the output is pulled to 2.0V or open, enabled on TDIS
