Finisar compatible FTLX8571D3BCL Description
EdgeOptic's FTLX8571D3BCL compatible is a Finisar (Coherent Corp)-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. The OEM Finisar FTLX8571D3BCL is end-of-life and no longer manufactured by Coherent, engineers with this SKU on a parts list need an active production replacement. The EdgeOptic compatible is that replacement, programmed with Finisar-recognized EEPROM and engineered to drop in wherever the original FTLX8571D3BCL is documented.
Optical specs follow the 10G-SFP-300 root: 850 nm transmit and receive, 20 nm bandwidth (840 to 860 nm), 300 m over OM3 and 400 m over OM4 / OM5 multimode fiber, duplex LC/UPC connector, 6.1 dB average link budget. Transmit power is −5 to 0 dBm, receiver sensitivity is −11.1 dBm, and receiver overload is 0 dBm. The transmitter is a VCSEL laser, the receiver a PIN photodiode, and DOM/DDM is supported per SFF-8472 for monitoring TX bias, optical power, voltage and case temperature.
The trailing BCL in the Finisar SKU denotes a 10G-only optic in Finisar's SFP+ product line, with no 1000BASE-SX fallback. The BCV variant is the dual-rate 1G/10G part. Existing OEM suffix variants of the FTLX8571D3BCL family, including -FC (Fibre Channel), -J1, -QL, and -EM, are covered by the EdgeOptic compatible's universal vendor coding. Verify the specific suffix on your BOM against the EdgeOptic order confirmation; for less common suffixes, request EEPROM verification at quote stage.
Standard commercial temperature 0 to 70 °C, +3.3 V single-supply power, IEEE 802.3ae-compliant 10GBASE-SR signaling, SFF-8431 SFP+ MSA, SFF-8432 mechanical, SFF-8472 diagnostic monitoring. The EdgeOptic compatible inherits the 10G-SFP-300 root's protocol scope: 10G Ethernet, 1G / 2G / 4G / 8G / 10G Fibre Channel, and STM-64 SDH where the host platform exposes those modes on the port.
For new deployments where you have flexibility on the OEM SKU, the active Finisar / Coherent replacement is the FTLX8574D3BCL, which uses the same BCL 10G-only profile and matching optical specs. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions
Is the OEM Finisar FTLX8571D3BCL end-of-life, and does the EdgeOptic compatible still ship?
Yes. The original Finisar (now Coherent Corp) FTLX8571D3BCL is end-of-life and no longer manufactured. The EdgeOptic compatible is in active production, ships from EU stock, and is engineered to drop into the same role across the documented suffix variants (-FC, -J1, -QL, -EM). For new deployments, the active OEM replacement is the FTLX8574D3BCL, which uses the same BCL 10G-only profile.
Does the FTLX8571D3BCL support 1000BASE-SX 1 G fallback, or is it 10 G only?
The BCL suffix in the Finisar SFP+ product line denotes a 10G-only optic with no 1000BASE-SX fallback. The dual-rate 1G/10G variant in the same family is BCV (FTLX8571D3BCV). If your deployment includes legacy 1G ports that need autonegotiation to 1000BASE-SX, you need a BCV-class part rather than a BCL. Verify the suffix on your BOM matches the host platform's expected rate before ordering.
