FTLX8574D3BCV

Product Specification 1G/10G 850nm Multimode Datacom SFP+ Transceiver FTLX8574D3BCV PRODUCT FEATURES • Hot-pluggable SFP+ footprint • Supports rate selectable 1.25 Gb/s or 9.95 to 10.3 Gb/s bit rates • Power dissipation < 1W • RoHS-6 compliant (lead-free) • Commercial temperature range -5°C to 70°C • Single 3.3V power supply • Maximum link length of 400m on OM4 MMF • Uncooled 850nm VCSEL laser • Receiver limiting electrical interface . APPLICATIONS • 1000BASE-SX 1G Ethernet • • Duplex LC connector • Built-in digital diagnostic functions 10GBASE-SR/SW 10G Ethernet Finisar’s FTLX8574D3BCV 1G/10G Dual-Rate SFP+ transceivers are designed for use in 1-Gigabit and 10-Gigabit Ethernet links over multimode fiber. They are compliant with SFF-84311, IEEE 802.3-2012 10GBASE-SR/SW2 and 1000BASE-SX3. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF84724. The FTLX8574D3BCV 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 interoperability with an SFP+ limiting module. This product is for applications specifically designed for 10G SFP+ ports and 1G/10G SFP+ ports and not native 1G SFP ports. The optical transceiver is compliant per the RoHS Directive 2011/65/EU5. See Finisar Application Note AN-20386 for more details. PRODUCT SELECTION FTLX8574D3BCV  Finisar Corporation - June 2015 Rev. B Page 1 FTLX8574D3BCV Product Specification I.

T is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the host board FAULT 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
