Finisar compatible FTLC1156RDPL Description
EdgeOptic's FTLC1156RDPL compatible is a Finisar/Coherent-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. Finisar was acquired by II-VI Incorporated in 2019 and rebranded as Coherent Corp in 2022, so the same module appears in current procurement as both Finisar FTLC1156RDPL and Coherent FTLC1156RDPL. The EdgeOptic compatible carries Finisar/Coherent-recognized EEPROM identifiers so the host adapter or switch surfaces the expected ordering code in CLI and management telemetry. The module slots into a standard QSFP28 cage and follows the same insertion, hot-swap, and DDM behavior as the OEM module.
The optical interface follows IEEE 802.3ba Clause 88 100GBASE-LR4. Four 25.78 Gbps NRZ lanes ride the LAN WDM grid at 1295.56, 1300.05, 1304.58, and 1309.14 nm, then multiplex onto a single LC duplex pair of single-mode fiber. The 6.3 dB optical path loss budget supports a full 10 km reach on G.652 SMF. Host electrical interface is CAUI-4 per IEEE 802.3bm. Power dissipation stays at 3.5 W on a single 3.3 V supply, the operating temperature window is 0 to 70 C commercial, and the module reports DDM telemetry per SFF-8636 for tx power, rx power, bias current, supply voltage, and case temperature.
The FTLC1156RDPL is the 103.1 Gbps Ethernet-only variant of the FTLC1156 family. Engineers building toward OTU4 transport at 111.81 Gbps on the same wavelength plan should reference the FTLC1156SDPL (S suffix) instead. The FTLC1156RDPL-1Y carries the same optical specifications under a Coherent ordering catalog suffix. EdgeOptic's compatible matches the original optical and electrical specifications and carries the FTLC1156RDPL ordering code so procurement records and chassis inventory output stay consistent with the Finisar/Coherent part numbering. The compatible carries Class 1 laser safety classification, RoHS compliance, and CE marking.
Works on QSFP28 hosts that accept third-party 100GBASE-LR4 optics per the QSFP28 MSA; verify the entry for your specific NIC, switch, or router in the vendor's transceiver compatibility matrix before deployment. Ships next business day from EU stock with a lifetime warranty. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.

Frequently Asked Questions
What is the difference between FTLC1156RDPL, FTLC1156RDPL-1Y, and FTLC1156RDPL2?
All three share the same 100GBASE-LR4 optical interface, the same LAN WDM wavelength plan (1295.56, 1300.05, 1304.58, 1309.14 nm), the same 10 km reach on SMF, and the same QSFP28 form factor. The base FTLC1156RDPL is the standard ordering reference. The -1Y suffix on FTLC1156RDPL-1Y is a Coherent ordering catalog code with no documented technical change to the optical specification. For FTLC1156RDPL2, confirm the exact ordering code and variant scope with Coherent via contact our sales team to confirm which ordering code matches the part number called out in your equipment configuration.
What is the difference between FTLC1156RDPL and FTLC1156SDPL?
The R suffix on FTLC1156RDPL indicates the 100GBASE-LR4 Ethernet-only variant at a 103.1 Gbps line rate. The S suffix on FTLC1156SDPL indicates the multirate variant that adds OTU4 transport at 111.81 Gbps on the same LAN WDM wavelength plan. Both share the same 10 km reach on SMF, the same LC duplex connector, and the same QSFP28 form factor. Engineers running a pure Ethernet link can use the R variant; engineers building toward OTN-framed transport on the same fibre should specify the S variant.
Can the FTLC1156RDPL replace an FTLC1151RDPL or FTLC1154RDPL in an existing link?
Yes for the optical layer. All three Finisar/Coherent generations operate on the IEEE 802.3ba 100GBASE-LR4 LAN WDM wavelength grid, present a duplex LC connector, support the same 10 km reach on G.652 SMF, and follow the QSFP28 MSA electrical interface. Generational differences are manufacturing and packaging updates, not changes to the optical interoperability layer. Verify the entry for your specific host platform in the vendor's transceiver compatibility matrix before swapping a deployed module.
