Finisar compatible FTLC1156RDPL2 Description

EdgeOptic's FTLC1156RDPL2 compatible is a Coherent/Finisar-coded 100GBASE-LR4 QSFP28 transceiver built on our 100G-QSFP28-10 platform. FTLC1156RDPL2 is the active Coherent ordering code in the FTLC1156RDPL family. II-VI acquired Finisar in September 2019, and II-VI rebranded to Coherent Corp. in September 2022, the FTLC1156 part number carries through unchanged. Datasheets and listings under the Finisar or II-VI brand refer to the same module family.

DigiKey lists FTLC1156RDPL2 as the recommended substitute for FTLC1154RDPL2, which is flagged not recommended for new designs. For new builds, DigiKey's substitute recommendation points to FTLC1156RDPL2; for existing FTLC1154RDPL2 deployments, EdgeOptic continues to stock the FTLC1154RDPL2-coded compatible separately. Order the exact SKU your line card expects so EEPROM identification matches the qualified-optics list.

Optical link budget is 6.3 dB per IEEE 802.3ba Clause 88, supporting up to 10 km over OS2 (G.652.D) single-mode fiber. The module runs 4-channel LAN-WDM at 1295.56, 1300.05, 1304.58, and 1309.14 nm; per-lane line rate is 25.78125 Gbps NRZ for an aggregate of 103.1 Gbps. 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; the module operates within the QSFP28 SFF-8665 cage power budget.

Coding: FTLC1156RDPL2 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.

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

Is FTLC1156RDPL2 a replacement for FTLC1154RDPL2?

DigiKey lists FTLC1156RDPL2 as a recommended substitute for FTLC1154RDPL2, which is flagged not recommended for new designs. Both are Coherent/Finisar 100GBASE-LR4 QSFP28 modules at 4x25G LAN-WDM, 10 km SMF, LC duplex, 6.3 dB link budget. For new builds, DigiKey's substitute recommendation points to FTLC1156RDPL2; for existing FTLC1154RDPL2 deployments, EdgeOptic continues to supply the legacy compatible separately so you don't have to recertify the optic in your platform's qualified-optics list. If your line card explicitly lists FTLC1154RDPL2 as the qualified SKU, order that part; if it lists FTLC1156RDPL2 or accepts both, the substitution is straightforward.
