Finisar compatible FTLX8574D3BCV Description

The FTLX8574D3BCV adds dual-rate 1G/10G capability to the Finisar (now Coherent) 10GBASE-SR SFP+ line, supporting both 1000BASE-SX and 10GBASE-SR in a single module. It operates at 850 nm over multimode fiber and replaces the earlier FTLX8571D3BCL in applications that require both 1000BASE-SX and 10GBASE-SR in the same module. EdgeOptic's compatible replacement matches the original specifications and ships with vendor-appropriate EEPROM coding.

The transceiver operates at 850 nm using a VCSEL laser with LC/UPC duplex connectors. On OM3 multimode fiber it reaches 300 m; on OM4 or OM5, 400 m. The module provides a 6.1 dB optical link budget and multi-rate operation from 1.25 to 10.3125 Gbps per SFF-8431.

The FTLX8574D3BCV and the older FTLX8571D3BCL share a similar part number but differ in a key way. The BCV is a later-generation dual-rate module; the BCL is 10G-only and does not support 1000BASE-SX fallback. Both share the same 10GBASE-SR optical parameters (850 nm, 300 m OM3, 6.1 dB budget), but the BCV adds 1G capability. The -IT suffix variant (FTLX8574D3BCV-IT) is the same optical hardware with Intel-specific EEPROM coding for Intel X520/X710 NICs.

The FTLX8574D3BCV is deployed across multi-vendor environments including Cisco Nexus and Catalyst, Juniper QFX and EX, HPE/Aruba switches, and Dell servers. The module is compliant with SFF-8431 and SFF-8432 MSA standards and carries CE/RoHS certification.

Frequently Asked Questions

What is the difference between FTLX8574D3BCV and FTLX8571D3BCL?

The FTLX8574D3BCV is a later-generation dual-rate module supporting both 1000BASE-SX (1G) and 10GBASE-SR (10G). The FTLX8571D3BCL is 10G-only and does not support 1G fallback. Both share the same 10GBASE-SR optical parameters: 850 nm, 300 m OM3, 6.1 dB budget. If dual-rate capability is required, specify the BCV.

Is the FTLX8574D3BCV-IT (Intel variant) the same module as the FTLX8574D3BCV?

Yes, optically and electrically. The -IT suffix denotes Intel-coded EEPROM for use in Intel X520/X710 NICs. The laser, receiver, and fiber parameters are identical to the base FTLX8574D3BCV. EdgeOptic's compatible can be ordered with either Finisar-standard or Intel-specific EEPROM coding.

Is the FTLX8574D3BCV compatible with Cisco, Juniper, and HPE switches?

Yes. The FTLX8574D3BCV is a standard 10GBASE-SR SFP+ transceiver deployed across multi-vendor environments. EdgeOptic's compatible version has been tested on Cisco Nexus and Catalyst, Juniper QFX and EX, and HPE/Aruba platforms. Specify the target vendor when ordering for correct EEPROM coding.
