Finisar Transceiver Product Specification Industrial Temperature 10Gb/s 850nm SFP+ Datacom Transceiver FTLX8574D3BTL PRODUCT FEATURES Hot-pluggable SFP+ footprint Supports 9.95 to 10.5 Gb/s bit rates Power dissipation < 1W RoHS compliant Industrial temperature range -40C to 85C Single 3.3V power supply Maximum link length of 400m on OM4 MMF Uncooled 850nm VCSEL laser APPLICATIONS Receiver limiting electrical interface CPRI options 2 through 8 Duplex LC connector 10GBASE-SR/SW 10G Ethernet Built-in digital diagnostic functions 1200-Mx-SN-I 10G Fibre Channel II-VIs FTLX8574D3BTL Industrial Temperature 10Gb/s SFP+ transceivers are designed for use in 10-Gigabit Ethernet links over multimode fiber. They are compliant with SFF- 1 2 3 8431 , SFF-8432 , IEEE 802.3-2012 10GBASE-SR/SW and 10G Fibre Channel 1200- 4 Mx-SN-I . Digital diagnostics functions are available via a 2-wire serial interface, as 5 specified in SFF-8472 . The FTLX8574D3BTL 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. 7 The optical transceiver is RoHS compliant as described in Application Note AN-2038 .

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. Should be pulled up with 4.7k 10k on host board to a voltage between 2.0V and 3.6V. MOD ABS pulls line low to indicate module is plugged in. 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.
