Product Specification RoHS-6 Compliant 10Gb/s Industrial Temperature 10km Single Mode Datacom SFP+ Transceiver FTLX1471D3BTL PRODUCT FEATURES Hot-pluggable SFP+ footprint Supports 9.95 to 10.5Gb/s bit rates Power dissipation < 1W RoHS-6 compliant (lead-free) Industrial temperature range -40C to 85C Single 3.3V power supply Maximum link length of 10km Uncooled 1310nm DFB laser APPLICATIONS Receiver limiting electrical interface 10GBASE-LR/LW 10G Ethernet Duplex LC connector 1200-SM-LL-L 10G Fibre Channel Built-in digital diagnostic functions Finisars FTLX1471D3BTL 10Gb/s Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 10km over Single 1 2 Mode fiber. They are compliant with SFF-8431 , SFF-8432 and IEEE 802.3ae 3 4 10GBASE-LR/LW , and 10G Fibre Channel 1200-SM-LL-L Digital diagnostics 5 functions are available via a 2-wire serial interface, as specified in SFF-8472 . The FTLX1471D3BTL is a limiting module, i.e., it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturers recommended settings for interoperating the host-board EDC PHY with a limiting receiver SFP+ module. The optical transceiver is compliant per the RoHS Directive 2011/65/EU. See Finisar Application Note AN-2038 for more details. PRODUCT SELECTION FTLX1471D3BTL Finisar Corporation - August 2015 Rev.

T is an open collector/drain output, which should be pulled up with a 4.7k 10k Ohms resistor on FAULT 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 <0.8V. 3. Laser output disabled on T >2.0V or open, enabled on T <0.8V. DIS DIS 4. Internally pulled down per SFF-8431 Rev 4.1. 5. LOS is open collector output. Should be pulled up with 4.7k 10k on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation logic 1 indicates loss of signal.
