Finisar compatible FTLX8574D3BxV Description

EdgeOptic's 10G-SFP-300 compatible is a Finisar-coded 10GBASE-SR SFP+ transceiver matching part number FTLX8574D3BxV. In Finisar's naming scheme, FTLX8574 designates a 10G SR higher-qualification-tier commercial module, distinct from the standard FTLX8571 variant. Finisar was acquired by II-VI in 2019, and II-VI rebranded as Coherent, but the FTLX8574 part number remains widely referenced in switch and server compatibility matrices across multiple vendors. The FTLX8574D3BxV operates at 10.3125 Gbps per IEEE 802.3ae over 850 nm VCSEL, delivering 300m reach on OM3 and 400m on OM4 multimode fiber with a 6.1 dB link budget. EdgeOptic programs the EEPROM with Finisar-compatible vendor identifiers so the module is recognized on platforms that validate against Finisar's vendor ID during transceiver initialization. This includes switches from Cisco, Juniper, Arista, and other vendors whose compatibility lists reference the FTLX8574 family.

The transceiver uses an 850 nm VCSEL transmitter and PIN photodiode receiver. DDM/DOM diagnostics report TX power, RX power, temperature, supply voltage, and laser bias current for real-time link health monitoring. The "D3BxV" in the part number denotes a specific revision and voltage variant within Finisar's product line. Duplex LC connectors, 0 to 70 degrees C operating temperature. The module also supports lower data rates including 1G Ethernet (1.25 Gbps) depending on the host port configuration. The FTLX8574 is Finisar’s higher-qualification-tier commercial module within the same 0 to 70 degrees C operating range, such as dense rack deployments with constrained airflow. This makes the FTLX8574D3BxV a common specification reference in data center environments where thermal margins are tighter than typical enterprise installations.

EdgeOptic's FTLX8574D3BxV compatible is CE/RoHS certified and compliant with the SFP+ MSA SFF-8432 specification. Each unit undergoes optical power measurement, connector inspection, and EEPROM validation before shipment. The module operates at 0 to 70 degrees C commercial grade and draws under 1 W, consistent with the SFP+ thermal envelope. EdgeOptic's compatible is independently manufactured and remains available regardless of Coherent's product lifecycle decisions for legacy Finisar SKUs.

Frequently Asked Questions

How does the FTLX8574D3BxV differ from the FTLX8571D3BCL?

Both are Finisar 10GBASE-SR SFP+ modules at 850 nm with identical optical specifications (wavelength, reach, power budget). The FTLX8574 is Finisar's extended-temperature commercial-grade variant, validated for more demanding thermal environments. The FTLX8571 is the standard commercial-grade module. The difference is in operating temperature qualification and part number lineage within Finisar's catalog.

Is the FTLX8574D3BxV still available from Finisar/Coherent?

Finisar's product line is now managed by Coherent (formerly II-VI). Availability and lead times for specific legacy Finisar SKUs vary by region and distributor. EdgeOptic's compatible FTLX8574D3BxV is independently manufactured to the original specifications and remains continuously available.
