Finisar 1G/10G Dual-Rate SFP+ Transceiver

The Finisar FTLX8571D3BCV is a dual-rate SFP+ transceiver built for 1-Gigabit and 10-Gigabit Ethernet links over multimode fibre. It serves network administrators upgrading or maintaining enterprise switches and routers that accept SFP+ modules. The unit complies with SFF-84311, IEEE 802.3-2005 10GBASE-SR/SW and 1000BASE-SX standards. Digital diagnostics are available through a 2-wire serial interface per SFF-84724.

Installation and common issues

The module inserts directly into a compatible SFP+ cage and locks with the standard bail latch. Because it is a limiting module, host boards using an EDC PHY IC must follow the IC manufacturer's recommended settings for interoperability. A frequent mistake is inserting the transceiver into a native 1G SFP port, which this product does not support. Always verify the port type before seating the module.

Pre-order checks

Confirm that your switch or router provides 10G SFP+ ports or 1G/10G SFP+ ports rather than native 1G SFP ports. Ensure the multimode fibre cabling matches the 10GBASE-SR/SW and 1000BASE-SX wavelengths used by this transceiver. Check that the host system can read digital diagnostics over the 2-wire serial interface if monitoring is required. The product is RoHS compliant and lead-free per Directive 2002/95/EC.

Questions about this item

How can I confirm the FTLX8571D3BCV is operating correctly after installing it in a 10G SFP+ port?

Check the host system for a recognised 1G/10G link and verify digital diagnostics over the 2-wire serial interface per SFF-84724.

What comes with the FTLX8571D3BCV and what must be sourced separately?

The transceiver itself is supplied; multimode fibre patch cables and compatible 1G/10G SFP+ switch ports are not included.

Which version of the FTLX8571D3BCV should I select for a 10GBASE-SR link over multimode fibre?

This single dual-rate model covers both 1G and 10G Ethernet over multimode fibre per IEEE 802.3-2005 10GBASE-SR/SW and 1000BASE-SX.
