Product Specification 10Gb/s 850nm Multimode Datacom SFP+ Transceiver FTLX8574D3BCL PRODUCT FEATURES Hot-pluggable SFP+ footprint Supports 9.95 to 10.5 Gb/s bit rates* Power dissipation < 1W RoHS-6 compliant (lead-free) Commercial temperature range -5C to 70C Single 3.3Vpower supply Maximum link length of 400m on OM4 MMF APPLICATIONS Uncooled 850nm VCSEL laser Receiver limiting electrical 10GBASE-SR/SW 10G Ethernet interface 1200-Mx-SN-I 10G Fibre Channel Duplex LC connector Built-in digital diagnostic functions Finisars FTLX8574D3BCL 10Gb/s SFP+ transceivers are designed for use in 10-Gigabit 1 2 Ethernet links over multimode fiber. They are compliant with SFF-8431 , SFF-8432 , 3 4 IEEE 802.3-2012 10GBASE-SR/SW and 10G Fibre Channel 1200-Mx-SN-I . Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF- 5 8472 . The FTLX8574D3BCL 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 6 7 2011/65/EU . See Finisar Application Note AN-2038 for more details.

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.
