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 -5°C to 70°C • Single 3.3Vpower supply • Maximum link length of 400m on OM4 MMF • Uncooled 850nm VCSEL laser APPLICATIONS • Receiver limiting electrical interface • 10GBASE-SR/SW 10G Ethernet • Duplex LC connector • 1200-Mx-SN-I 10G Fibre Channel • Built-in digital diagnostic functions Finisar’s FTLX8574D3BCL 10Gb/s SFP+ transceivers are designed for use in 10-Gigabit Ethernet links over multimode fiber. They are compliant with SFF-84311, SFF-84322, IEEE 802.3-2012 10GBASE-SR/SW3 and 10G Fibre Channel 1200-Mx-SN-I4. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF84725. 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 manufacturer’s 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/EU6. See Finisar Application Note AN-20387 for more details.

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
