Finisar compatible FTLF8536P4PCL Description
EdgeOptic's FTLF8536P4PCL compatible is a Finisar-coded dual-rate 10GBASE-SR / 25GBASE-SR SFP28 transceiver that matches the original Finisar (now Coherent Corp) FTLF8536P4PCL datasheet (September 2017, Rev A). The PCL suffix identifies the pull-tab release mechanism - a direct variant of the bail-latch FTLF8536P4BCL that is otherwise optically equivalent. Line rate range is 8.5 - 28.1 Gbps, covering 10.3125 Gbps for 10GBASE-SR and 25.78125 Gbps for 25GBASE-SR.
Optics: 850 nm oxide VCSEL transmitter, PIN photodiode receiver, TX power -8.4 to +2.4 dBm, RX sensitivity better than -10.3 dBm. Reach is 100 m on OM4, 70 m on OM3, and 20 m on OM2 per the P4PCL datasheet - the OM2 leg is unique to the P4 generation documentation and is useful in legacy MMF plants that have not been upgraded. Connector is LC/UPC duplex. IEEE 802.3by Clause 112 applies at 25G with RS-FEC via Clause 91 (RS(528,514)); at 10G the module runs at 10.3125 Gbps without host FEC.
Electrical interface follows SFF-8431, SFF-8432, and SFF-8402. Digital diagnostics are SFF-8472 Rev 12.2 compliant, reporting temperature, supply voltage, TX bias, TX power, and RX power. Maximum power consumption is 1.2 W from a single 3.3 V supply - higher than the 0.3 W typical of the P5 generation and a budget consideration when populating a fully loaded SFP28 chassis with P4-generation optics. Operating temperature range is 0-70 C and the part is RoHS compliant.
The PCL variant was specified into equipment populations that required pull-tab release rather than bail-latch - typically dense front-panel layouts where bail-latch actuation was mechanically awkward. The 2017 Finisar datasheet covers the P4 generation; Finisar later issued the P5 series (FTLF8536P5BCL / P5BCV) as the lower-power successor for new deployments. Existing P4PCL installations often stay on the exact P4PCL part because the pull-tab form factor is spec'd on the BOM.
For P4PCL-populated slots where the pull-tab release is a BOM requirement and the 1.2 W budget is already accounted for, contact our sales team.
Frequently Asked Questions
What is the difference between the FTLF8536P4PCL and the FTLF8536P4BCL?
The difference is the connector release mechanism. The PCL is a pull-tab release; the BCL is a bail-latch release. Optical specifications are identical - 850 nm VCSEL, 100 m OM4, 70 m OM3, 5.3 dB link budget, IEEE 802.3by Clause 112. Pull-tab variants are ordered when the front-panel density makes bail-latch actuation impractical. The power envelope is also different on the P4 generation: the PCL datasheet lists 1.2 W maximum, while newer P5 bail-latch parts list 0.3 W.
The FTLF8536P4PCL datasheet lists 1.2 W maximum power. Does this affect thermal planning vs P5 bail-latch modules?
Yes, in dense SFP28 populations. The P4 series was a higher-power generation, and the 1.2 W envelope is four times the 0.3 W figure on the P5 series. For a chassis already populated with P4PCL and a thermal profile budgeted around that, the EdgeOptic compatible holds to the same 1.2 W worst-case. For a migration toward P5 parts, switch to the FTLF8536P5BCL bail-latch or FTLF8536P5BCV dual-rate compatible where the chassis BOM allows it.
Does the FTLF8536P4PCL support 10G operation in addition to 25G?
Yes. The Finisar FTLF8536P4PCL datasheet names 25GBASE-SR (25.78 Gbps) and 10GBASE-SR (10.31 Gbps) as supported applications. The 8536 series carries dual-rate support across generations. The host port determines which Ethernet rate the module runs at; the EEPROM exposes both rates. Note: no FEC is applied at 10G, while 25G operation with RS-FEC follows IEEE 802.3by Clause 91 at the host.
The P4PCL datasheet lists a 20 m reach on OM2 fiber. Is that real, or a typo for OM3?
It is real. The 2017 Finisar FTLF8536P4PCL datasheet explicitly lists 20 m reach over 50/125 um OM2 fiber, alongside 70 m on OM3 and 100 m on OM4. OM2 is generally out of the IEEE 802.3by link-budget specification, but Finisar characterized the P4 generation on OM2 for legacy plants. Newer P5 datasheets dropped the OM2 reach figure. If the plant is running OM2 and distances are short, the P4PCL will close the link; for any greenfield fiber, OM3 or OM4 is the correct choice at 25G.
