Finisar compatible FTLF8536P4PCL Description
EdgeOptic's FTLF8536P4PCL compatible is a Finisar-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver, a direct replacement for the Coherent (formerly Finisar) FTLF8536P4PCL pull-tab variant. It ships with Finisar-recognized EEPROM and the pull-tab release mechanism for chassis cage layouts that require finger access on the pull side. The optic is dual-rate, supporting 10GBASE-SR and 25GBASE-SR on the same physical interface.
Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multimode fiber: 100 m on OM4 or OM5, 70 m on OM3. Line signaling rate is 25.78125 Gbd, with dual-rate operation down to 10.3125 Gbd for 10GBASE-SR on mixed-speed infrastructure. TX power −5 dBm minimum and +2.4 dBm maximum from an 850 nm oxide VCSEL, RX sensitivity −10.3 dBm on the PIN photodiode receiver, 5.3 dB link budget with host RS-FEC per IEEE 802.3by Clause 108 RS(528,514). Duplex LC/UPC connector, DOM per SFF-8472, 0.3 W maximum power, 0 to 70 °C commercial operating range.
The FTLF8536P4PCL is the pull-tab variant of Finisar's P4 generation 25GBASE-SR / 10GBASE-SR SFP28. The later P5 generation (FTLF8536P5BCL, FTLF8536P5BCV) brought the OEM power envelope down to 0.3 W; the EdgeOptic FTLF8536P4PCL compatible is built to that same 0.3 W root specification, drawing less than the original P4 OEM module while preserving the pull-tab release. The Finisar product line is now part of Coherent Corp.
Platform scope is 25 GbE SFP28-capable hosts and switches that accept Finisar-coded modules through standard SFF-8472 EEPROM access. The pull-tab variant suits cage layouts where bail-latch finger access is obstructed. Verify chassis EEPROM acceptance policy before deployment at scale.
DOM registers for transmit power, receive power, supply voltage, laser bias and module case temperature are exposed through SFF-8472 and accessible via standard ethtool reads on Linux hosts. The optic meets the 25GBASE-SR optical specification per IEEE 802.3by Clause 112, with host RS-FEC at the MAC layer per IEEE 802.3by Clause 108 where the link partner requires it.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions about FTLF8536P4PCL
What is the difference between the FTLF8536P4PCL and the FTLF8536P4BCL?
The FTLF8536P4PCL is the pull-tab release variant; the FTLF8536P4BCL is the bail-latch release variant. Both carry the same Finisar P4 generation 25GBASE-SR / 10GBASE-SR SFP28 optical specification. The 850 nm oxide VCSEL transmitter, PIN photodiode receiver, OM3 and OM4 reach, and OEM optical and power envelopes are identical between the two. The release mechanism choice is driven by cage density and finger access on the host chassis, not by optical performance. Match the variant the chassis vendor specifies in the QuickSpecs or service guide.
The original Finisar P4 datasheet lists 1.2 W maximum power. Does the EdgeOptic compatible draw the same?
No. The original Finisar P4 generation (FTLF8536P4PCL and FTLF8536P4BCL) was characterized at 1.2 W maximum power. The EdgeOptic FTLF8536P4PCL compatible is built to the 25G-SFP28-100 root specification at 0.3 W maximum, the same lower-draw envelope as the Finisar P5 successor generation. The reduction is a benefit in dense-rack 25 GbE deployments where SFP28 cage thermal budget is constrained: lower per-port draw eases cage cooling without changing the optical interface. The pull-tab release is preserved for compatibility with chassis whose cage layout requires it.
The original P4 datasheet lists a 20 m reach on OM2 fiber. Does the EdgeOptic compatible support OM2?
The original Finisar P4 datasheet characterized 20 m on OM2. The EdgeOptic FTLF8536P4PCL compatible follows the 25G-SFP28-100 root specification, which is defined for OM3 (70 m), OM4 (100 m) and OM5 (100 m) multimode grades. OM2 is not part of the root specification. For 25 GbE links over legacy OM2 cabling under 20 m, contact our sales team for a deployment assessment before ordering at scale.
