Finisar compatible FTLX8574D3BCL-1T Description
EdgeOptic's FTLX8574D3BCL-1T compatible is a Finisar-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. Finisar-recognized EEPROM lets the optic register cleanly on platforms that originally shipped with Finisar OEM optics, so the host accepts the module without a vendor-mismatch alert. One universal SR hardware platform, 80+ vendor codes, including this Finisar -1T variant.
Optical specifications, 10GBASE-SR class. 850 nm VCSEL transmitter, PIN photodiode receiver, multi-mode duplex LC. Reach is 300 m on OM3 and 400 m on OM4. TX output power runs −5 to 0 dBm, receiver sensitivity −11.1 dBm, receiver overload 0 dBm, link budget 6.1 dB. Multi-rate capability spans 1.25 to 11.32 Gbps, covering 10G Ethernet, Gigabit Ethernet, 1G to 10G Fibre Channel, and STM-64. DDM/DOM supported for live link diagnostics. Compliance: SFF-8431, SFP MSA, IEEE 802.3ae, RoHS, IEC60825-1 Class 1 laser safety. Operating range 0 to 70°C commercial.
FTLX8574D3BCL-1T is a Finisar order code in the FTLX8574 multi-rate 10GBASE-SR SFP+ family. The base FTLX8574D3BCL part covers a multi-rate envelope from 1G to 10G that matches the EdgeOptic 10G-SFP-300 platform specification. Finisar was acquired by II-VI in 2019 and II-VI merged with Coherent in 2022, so current Finisar optical product datasheets are published under the Coherent product portfolio; the 'Finisar' brand name remains widely used in search and on procurement documents from the pre-acquisition era.
The -1T suffix is an OEM-coding or revision identifier in Finisar's part-number scheme; the optical specifications match the base FTLX8574D3BCL described above. Distinct variants in the same family carry their own order codes, for example FTLX8574D3BCL-PS is a separate Finisar variant visible in supply-chain catalogs. Match the exact suffix on the original BOM line item when ordering replacement units, since downstream system vendors may have qualified a specific suffix for a given platform revision.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty included.

FTLX8574D3BCL-1T FAQ
What does the -1T suffix mean on FTLX8574D3BCL-1T?
The -1T suffix is an OEM-coding or revision identifier in Finisar's part-number scheme; Finisar uses suffix codes to distinguish EEPROM programming variants and platform revisions for downstream system vendors that have qualified a specific suffix for their products. The optical specifications match the base FTLX8574D3BCL: 850 nm VCSEL, 300 m on OM3 / 400 m on OM4, LC duplex, multi-rate envelope. The -1T variant is distinct from FTLX8574D3BCL-PS and other suffix variants in the same family. When selecting a replacement, match the exact suffix on the original purchase order; verify against the Coherent (formerly II-VI / Finisar) part-number list for your platform.
Is FTLX8574D3BCL a dual-rate or 10G-only module?
The FTLX8574D3BCL family is a multi-rate SFP+ that operates from 1 Gbps to 10 Gbps on the same hardware. The EdgeOptic compatible inherits the same multi-rate envelope, 1.25 to 11.32 Gbps, which covers 10G Ethernet, Gigabit Ethernet, 1G to 10G Fibre Channel, and STM-64. The -1T variant follows the same multi-rate optical design as the base part; the suffix affects EEPROM coding, not the physical-layer rate envelope. Confirm the host expects multi-rate behaviour rather than a strict 10G-only optic on platforms that read SFF-8472 rate-select bits.
