FTLX1374D3BCL

Preliminary Product Specification RoHS-6 Compliant 10Gb/s 1km Single Mode Datacom SFP+ Transceiver FTLX1374D3BCL PRODUCT FEATURES • Hot-pluggable SFP+ footprint • Supports 10.3Gb/s bit rate • Power dissipation < 1W • RoHS-6 compliant (lead-free) • Data Center temperature range 15°C to 55°C • Single 3.3V power supply • Maximum link length of 1km • 4 dB link budget • Receiver limiting electrical interface • Duplex LC connector • Built-in digital diagnostic functions APPLICATIONS • Data Center 10G Ethernet Finisar’s FTLX1374D3BCL 10Gb/s Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 1km over Single Mode fiber. The electrical interface is SFI compliant per SFF-84311, and is compliant to SFF-84322. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-84723. The FTLX1374D3BCL 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 transceiver is RoHS compliant and lead free per Directive 2011/65/EC4, and Finisar Application Note AN-20385. PRODUCT SELECTION FTLX1374D3BCL  Finisar Corporation - March 2015 Rev.

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
