Finisar compatible FTLC1154RDPL2 Description
EdgeOptic's FTLC1154RDPL2 compatible is a Coherent/Finisar-coded 100GBASE-LR4 QSFP28 transceiver built on our 100G-QSFP28-10 platform. FTLC1154RDPL2 is a Coherent/Finisar variant in the FTLC1154RDPL family. DigiKey flags FTLC1154RDPL2 as not recommended for new designs and lists FTLC1156RDPL2 as a recommended substitute. EdgeOptic continues to supply the FTLC1154RDPL2-coded compatible for existing deployments where the line card's qualified-optics list already references this exact SKU.
If you're sustaining an existing fleet that already lists FTLC1154RDPL2 as the qualified part, ordering the same code keeps EEPROM identification aligned with what the line card expects, no requalification needed. If you're scoping a new build, DigiKey's substitute recommendation points to FTLC1156RDPL2 as the current-production module. Both sit in the same 100GBASE-LR4 QSFP28 envelope: 4-channel LAN-WDM, 10 km SMF, LC duplex, 6.3 dB link budget per IEEE 802.3ba Clause 88.
The module runs four wavelength channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, each carrying 25.78125 Gbps NRZ for an aggregate of 103.1 Gbps. Reach is up to 10 km over OS2 (G.652.D) single-mode fiber. The dual LC/UPC connector accepts standard SMF patch cords and structured cabling. Reach in the deployed plant depends on connector loss and fiber attenuation, verify against the link budget at commissioning.
Digital diagnostic monitoring (DDM/DOM) reports per-lane TX and RX optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface. The module presents a CAUI-4 host electrical interface (4x25G NRZ) and is transparent to host-side RS-FEC running in the line-card ASIC. Operating temperature range is 0 to 70 C.
Coding: FTLC1154RDPL2 is a Coherent/Finisar multi-vendor module, not locked to a specific switch vendor. EdgeOptic's compatible carries Coherent/Finisar EEPROM identification, and most Arista, Dell, Intel, Juniper, and Nvidia QSFP28 ports accept it without manual configuration. Cisco NX-OS and certain Huawei VRP releases enforce a third-party transceiver policy; EdgeOptic can program the module with Cisco, Juniper, Arista, or Huawei coding on request to bypass any acceptance prompts. Coherent corporate lineage: II-VI acquired Finisar in September 2019, and II-VI rebranded to Coherent Corp. in September 2022, the FTLC1154 part number carries through unchanged.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. The module meets IEEE 802.3ba Clause 88 100GBASE-LR4 and the QSFP28 MSA SFF-8665, and is CE/RoHS-6 certified. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions
What is the difference between FTLC1154RDPL2 and FTLC1154RDPL?
Both are Coherent/Finisar 100GBASE-LR4 QSFP28 modules at 4x25G LAN-WDM, 10 km SMF, LC duplex, 6.3 dB link budget per IEEE 802.3ba Clause 88. Public Coherent documentation does not define what the '2' suffix denotes, so the precise difference between the two variants is not documented in accessible public sources. The practical signal: DigiKey flags FTLC1154RDPL2 as not recommended for new designs (with FTLC1156RDPL2 listed as the substitute), while the base FTLC1154RDPL remains an active sibling SKU. If your line card's qualified-optics list calls out FTLC1154RDPL2 by exact part number, order that part so EEPROM identification matches; if it lists the base FTLC1154RDPL, order that one instead.
Is there a current-production replacement for the FTLC1154RDPL2?
DigiKey lists FTLC1156RDPL2 as a recommended substitute for FTLC1154RDPL2, which it flags as not recommended for new designs. The two parts share the same 100GBASE-LR4 QSFP28 specification: 4x25G LAN-WDM, 10 km SMF, LC duplex, 6.3 dB link budget. For a new build, the substitute path is straightforward. For an existing deployment that already qualifies FTLC1154RDPL2 in its host platform's optics list, EdgeOptic continues to supply the FTLC1154RDPL2-coded compatible so the EEPROM identification matches what the line card expects, no requalification step needed.
