QLogic FTLX8574D3BCL-QL Compatible 10GBASE-SR SFP+ Module

EdgeOptic's FTLX8574D3BCL-QL compatible is a QLogic-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver, programmed to register cleanly inside QLogic host bus adapters and converged network adapters that read the vendor block during initialization. The -QL ordering code is the QLogic OEM-coded variant of the base FTLX8574D3BCL. The optical engine matches the base part: 850 nm VCSEL transmitter and 850 nm PIN photodiode receiver running at 10.3125 Gbps per IEEE 802.3ae Clause 52, with a duplex LC connector and full SFF-8472 digital diagnostics.

The link budget is 6.1 dB, sufficient for 300 m on OM3 multimode and 400 m on OM4. TX optical power sits between −5 and 0 dBm; RX sensitivity is better than −11.1 dBm. DDM telemetry exposes TX power, RX power, laser bias current, supply voltage, and module case temperature over the standard SFF-8472 I2C path; QLogic adapter management utilities surface the data per the adapter's DDM implementation. The QLogic vendor coding in the EEPROM differentiates this SKU from the base Finisar-coded FTLX8574D3BCL; verify the optic against the QLogic adapter's transceiver compatibility list before fleet deployment.

Built to the SFP+ MSA, SFF-8431, and IEC60825-1 Class 1 laser safety standards. Commercial operating range is 0 to 70 °C. The module supports the multi-rate envelope of the underlying EdgeOptic 10G-SFP-300 platform (1.25 to 11.32 Gbps), so the same hardware can carry 10G Ethernet, 1G Ethernet, 10G Fibre Channel, and STM-64 traffic where the host adapter rate-selects to the application; the QLogic EEPROM profile advertises the 10GBASE-SR capability set the adapter firmware expects to see. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
