Finisar compatible FTLF8536P5BNV Description

EdgeOptic's FTLF8536P5BNV compatible is a Finisar-coded dual-rate 10GBASE-SR / 25GBASE-SR SFP28 transceiver that matches the original Finisar FTLF8536P5BNV specification. The BNV suffix combines three positions: B = bail-latch release, N = extended 0-85 C case-temperature rating, V = OEM customer variant coding. The P5 generation is the distinction from the P4 BNV: the core silicon runs at 0.3 W maximum, roughly one-quarter of the 1.2 W P4 budget.

Optical path is the FTLF8536 family root spec: 850 nm VCSEL transmitter, PIN photodiode receiver, TX power -8.4 to +2.4 dBm, RX sensitivity better than -10.3 dBm, 5.3 dB link budget, LC/UPC duplex connector. Reach is 100 m on OM4 and OM5, and 70 m on OM3. The module is dual-rate across 10.3125 Gbps (10GBASE-SR) and 25.78125 Gbps (25GBASE-SR); the host port configuration selects the Ethernet rate. RS-FEC via Clause 91 (RS(528,514)) applies at 25GBASE-SR when the host port negotiates it.

The P5 + N combination is the hero of this part. P5 silicon delivers the same optics as P4 at a fraction of the per-module thermal contribution, which matters in high-density deployments where cage-column temperatures trend high. Pairing that efficiency with the N extended 0-85 C case rating produces a module that runs cool internally and tolerates elevated ambient - the combination that standard commercial BCL and BCV variants (rated 0-70 C only) cannot cover. Typical targets are dense 25G top-of-rack builds with hot aisles, converged fabric platforms in industrial-adjacent racks, and any deployment where switch-level power and thermal headroom are both constrained.

Electrical interface is SFP28 per SFF-8402 MSA with SFF-8431 / SFF-8432 for the cage. Digital diagnostics are SFF-8472 Rev 12.2 compliant, exposing per-module temperature, supply voltage, TX bias, TX power, and RX power. The module is hot-swappable and RoHS compliant per the original Finisar specification. The V coding designates an OEM customer variant - the exact OEM target for FTLF8536P5BNV is not published in public Finisar or Coherent documentation, so no specific OEM attribution is claimed. EdgeOptic's FTLF8536P5BNV compatible is coded to the Finisar EEPROM identity for drop-in replacement, and for slots that enforce a specific OEM signature the module can be coded during fulfillment to the target profile.

For dense 25G chassis where 0-85 C case-temperature operation and the P5 0.3 W power envelope are both deployment constraints, contact our sales team.

Frequently Asked Questions

How much power does the FTLF8536P5BNV draw, and how does that compare to the P4 generation?

The P5 generation is specified at 0.3 W maximum per port, compared with 1.2 W on the P4 generation - a roughly 75 percent reduction. In a fully populated 48-port SFP28 line card the module contribution to the thermal budget drops from 57.6 W (P4) to about 14.4 W (P5). The optical specification is identical between the two generations, so the choice between P4 and P5 is driven by the host deployment's power and thermal budget and by the existing slot population that is being refreshed or matched.

What distinguishes the FTLF8536P5BNV from the FTLF8536P5BCV (Lenovo ThinkSystem 4TC7A88638)?

The two parts share the P5 generation, bail-latch release, dual-rate FTLF8536 line, and OEM variant (V) coding class, but differ on temperature rating. BNV is rated 0-85 C extended, BCV is 0-70 C commercial. The BCV is the part Lenovo has published against ThinkSystem 4TC7A88638. The BNV is a different OEM customer variant - the specific host target is not published publicly. If the deployment environment stays within 0-70 C and the Lenovo order code is the procurement anchor, BCV is the correct match. If case temperature exceeds 70 C under sustained load, only BNV (or a B-series extended-temp part) closes the thermal spec.

Is the FTLF8536P5BNV dual-rate, and how is the 10G mode configured?

Dual-rate 10GBASE-SR and 25GBASE-SR. The FTLF8536 line EEPROM carries both 10.3125 Gbps and 25.78125 Gbps rate support; the host switch platform sets the operating rate per port. At 10GBASE-SR no host FEC is required. At 25GBASE-SR most modern host platforms enable RS-FEC (IEEE 802.3by Clause 91) by default. The module does not negotiate rate autonomously - if the host is not configured for the intended rate the link will not come up.

Why pair the P5 low-power variant with the N extended-temperature rating - is that combination necessary?

The two specs address different physical layers of the same thermal problem. P5 reduces the heat the module itself generates at the SFP28 cage. N extends the upper case-temperature limit the module can tolerate. A dense chassis in a hot aisle or an industrial-adjacent cabinet can satisfy both constraints simultaneously - the surrounding airflow runs warm, and dozens of populated ports compound the issue. A P5 module (lower self-heat) rated to 85 C case temperature covers the envelope that a P4 commercial (1.2 W at 70 C max) cannot. Picking either spec alone leaves the other side of the problem uncovered.
