Finisar compatible FTLF8536P5BCV Description
EdgeOptic's FTLF8536P5BCV compatible is a Finisar-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, programmed for dual-rate 10GBASE-SR and 25GBASE-SR operation on the same optic. The BCV suffix separates this part from the single-rate FTLF8536P5BCL sibling: DigiKey lists the FTLF8536P5BCV with 10 Gbps and 25 Gbps data rates, and the module negotiates at whichever rate the host port is configured for. Line rates are 10.3125 Gbps for 10GBASE-SR and 25.78125 Gbps for 25GBASE-SR, within the SFP28 SerDes operating range defined by SFF-8402.
Optical path is identical to the P5BCL: 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 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, 100 m on OM5, and 70 m on OM3. At 25GBASE-SR the module operates per IEEE 802.3by Clause 112 with RS-FEC per Clause 91 (RS(528,514)) when enabled by the host port. At 10GBASE-SR the module operates at 10.3125 Gbps per IEEE 802.3ae with no host FEC required.
Electrical interface is SFP28 per SFF-8402 MSA, with SFF-8431 and 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. Power dissipation is 0.3 W, the module is hot-swappable, the operating temperature range is 0 to 70 C commercial, and the part is RoHS compliant per the original Finisar specification.
Lenovo ThinkSystem 4TC7A88638 is Lenovo's dual-rate 10G/25G SR SFP28 transceiver, branded as a Finisar part on Lenovo's product page. The FTLF8536P5BCV matches that functional specification: P5-generation dual-rate 10GBASE-SR and 25GBASE-SR over 850 nm MMF with a 100 m OM4 reach. Lenovo does not publicly name the exact Finisar OEM P/N underneath the 4TC7A88638 label, so EdgeOptic positions the FTLF8536P5BCV compatible as a functional-spec match for 4TC7A88638 use cases rather than an EEPROM-exact drop-in unless the target slot accepts the standard Finisar P5BCV identity. Finisar merged with II-VI Incorporated in 2019 and II-VI rebranded as Coherent Corp in 2022, so the same transceiver also appears under Coherent Finisar branding in recent distribution channels.
The FTLF8536P5BCVFTN variant seen in some search results is a Finisar mechanical-housing designator, most commonly a pull-tab release in place of the standard bail-latch. Optical specifications (wavelength, reach, budget, rates) are unchanged. EdgeOptic's FTLF8536P5BCV compatible covers both the bail-latch and pull-tab mechanical variants from the same SKU.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For mixed 10G/25G slot policies where the FTLF8536P5BCV or the FTLF8536P5BCVFTN pull-tab variant is on the order line, or where Lenovo 4TC7A88638 is the stocked OEM code and a functional-match compatible is acceptable, contact our sales team.
Frequently Asked Questions
Does the FTLF8536P5BCV support both 10G and 25G, or is it 25G-only like the BCL?
The BCV suffix is the dual-rate designation. DigiKey lists the FTLF8536P5BCV at 10 Gbps and 25 Gbps data rates, so the module operates at 10GBASE-SR (10.3125 Gbps) or 25GBASE-SR (25.78125 Gbps) based on the host port configuration. That is the distinction from the BCL suffix in the Finisar nomenclature, where BCL is the single-rate 25G part. Lenovo qualified the BCV under the 4TC7A88638 ThinkSystem accessory as the dual-rate variant.
Can the FTLF8536P5BCV drop into a 25G-only port where an FTLF8536P5BCL was originally installed?
Yes at the optical layer. At 25GBASE-SR the BCV and BCL share the same optical path (850 nm VCSEL, 100 m OM4 reach, 5.3 dB budget) and the same SFP28 electrical. The host negotiates at 25G; the dual-rate EEPROM on the BCV does not force a 10G fallback. The caveat is host-side OEM EEPROM validation: if the platform only accepts the exact BCL EEPROM signature, EdgeOptic can code the BCV compatible to the target host identity during fulfillment on request.
What is the FTLF8536P5BCVFTN variant seen in some search results?
The FTN suffix is a Finisar mechanical-housing designator, most commonly indicating a pull-tab release in place of the standard bail-latch. Optical specifications (wavelength, reach, budget, rates) are unchanged. EdgeOptic's FTLF8536P5BCV compatible covers both the bail-latch and the pull-tab mechanical variant from the same SKU; specify the chassis cage clearance constraint at order time if the front-bezel rake matters for your installation.
