Finisar FTLF8528P3BCV Compatible 8GFC SFP+ Transceiver

EdgeOptic's FTLF8528P3BCV compatible is a Finisar-coded version of the EdgeOptic 10G-SFP-300 multi-rate SFP+ transceiver, built for 8 Gbps Fibre Channel (8GFC) short-wave deployments in storage-area networks. The module is the OEM base FTLF8528P3BCV part. Coded variants for individual OEM platforms (the -QL QLogic-coded sibling, the -HD HP-coded variant, and others) carry the same optical engine with different EEPROM vendor blocks. The FTLF8528P3BCV is tri-rate: 8.5 Gbps for 8GFC, 4.25 Gbps for 4GFC, and 2.125 Gbps for 2GFC. The SAN fabric port negotiates to the highest common rate during link bring-up.

Standard compliance follows FC-PI-4 Rev. 8.00 (INCITS 450-2008), the Fibre Channel Physical Interface specification for 8GFC short-wave optics, not IEEE 802.3, which applies to Ethernet. SFF-8472 Rev. 11.0 covers the digital diagnostics interface; the SFP+ MSA per SFF-8431 covers the mechanical and electrical envelope. The optical engine is an 850 nm oxide VCSEL transmitter paired with an 850 nm PIN photodiode receiver. The module reaches 150 m on OM3 multimode fiber at the full 8GFC rate per the Finisar/Coherent FTLF8528P3BCV datasheet; verify the OM3 reach class against the current Coherent datasheet before deploying onto production fabric. Reach extends on the lower-rate fallbacks (4GFC and 2GFC) because the bandwidth-distance product the fiber must satisfy is relaxed at lower line rates; deploy the optic against the rate carried by the fabric, not against the headline 8GFC reach.

SFF-8472 DDM/DOM publishes TX power, RX power, laser bias, supply voltage, and case temperature over the I2C interface, accessible through the SAN switch operating system's standard transceiver-diagnostic commands on Brocade Fabric OS and Cisco MDS NX-OS platforms. Duplex LC connector. Operating range covers the standard commercial envelope with a typical 0.5 W power consumption from the 3.3 V supply. RoHS-6 and CE compliant. The optic is unsuitable for 1GFC SAN fabrics, since 1GFC short-wave is outside the FC-PI-4 8GFC optic class and requires a dedicated 1GFC module.

Typical deployment is SAN core-edge fabric builds at 8GFC, mixed 4G and 8G migration windows during storage refresh, and open-coded inventory for integrators that keep a single 8GFC short-wave SKU on the shelf. For platforms that enforce a vendor-coded EEPROM, request the appropriate OEM-coded variant (the -QL QLogic-coded sibling for QLogic HBAs, or the equivalent vendor-coded part for the target switch). Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.
