Finisar compatible FTLF1428P2BNV Description
FTLF1428P2BNV is Finisar's part number for a second-generation 8G Fibre Channel long-wavelength SFP+ transceiver. EdgeOptic's compatible replacement is built on our 10G-SFP-10 platform, matching the original optical and electrical specifications. The P2BNV shipped alongside the first wave of 8GFC switch deployments and remains the most common revision in established FC SAN installations.
The P2BNV is the earlier production revision in the FTLF1428P series, preceded only by the original P1BNV that shipped with first-generation 8GFC switches. Finisar later released the P3BNV with updated EEPROM tables, but the P2 and P3 are optically identical and fully interchangeable in a live FC fabric. Installed-base environments with existing P2 inventory can mix P2 and P3 modules on opposite ends of a link without any compatibility issue. The P2 revision is significant in spares management because many FC SAN maintenance contracts reference the exact suffix from the original bill of materials.
The transmitter is a 1310 nm DFB laser; the receiver uses a PIN photodiode. Launch power is specified at -9.5 to -0.5 dBm, with receiver sensitivity of -17 dBm or better, providing a link budget that supports 10 km reaches over G.652 single-mode fiber through duplex LC/UPC connectors. DDM per SFF-8472 reports optical power (Tx and Rx), temperature, laser bias current, and supply voltage to the host management plane. SAN administrators use these DDM readings to monitor fiber plant health and predict module end-of-life based on bias current trending.
Dual-rate operation covers 4GFC (4.25 Gbps) and 8GFC (8.5 Gbps). The host port negotiates the line rate automatically based on the far-end capability. The P2BNV remains common in legacy FC SANs built around Brocade 300/5100, Cisco MDS 9124/9134, and QLogic SANbox switches, where spares procurement often references the P2 suffix specifically because that is what the original deployment documentation listed. These environments may have thousands of P2BNV modules installed across multiple fabric domains.
EdgeOptic programs the compatible with standard FC OUI data, ensuring clean FLOGI on Brocade Fabric OS, Cisco NX-OS/SAN-OS, and QLogic SANsurfer-managed fabrics. The DDM alarm thresholds match Finisar's original P2 specification. For spares kitting, legacy SAN maintenance, or bulk orders, contact our sales team
Frequently Asked Questions
Can the FTLF1428P2BNV be used as a direct replacement for the FTLF1428P3BNV?
Yes. The P2 and P3 revisions share identical optical parameters (1310 nm, 10 km, same power budget). The difference is an internal EEPROM revision. Both pass the same FLOGI sequence and are interchangeable on any port that accepts 8GFC LW SFP+ modules.
Why do some spare-parts lists still specify the P2BNV instead of the P3BNV?
Legacy SAN installations often reference the exact part suffix from the original purchase order. Switch firmware reads the transceiver's EEPROM and may display "P2BNV" in the inventory, so operations teams prefer to match the recorded suffix when ordering replacements. Functionally, either revision works.
