v2Complete technical specifications and product details
Finisar compatible FTLC1156RDPL-1Y Description
FTLC1156RDPL-1Y is a Coherent (formerly Finisar/II-VI) ordering variant of the FTLC1156RDPL, the current-production 100GBASE-LR4 QSFP28 transceiver. The -1Y suffix is a catalog code with no technical or optical difference from the base FTLC1156RDPL. This EDGE compatible module matches the original specifications and is built to the same MSA standards. It operates over duplex single-mode fiber at four LAN-WDM wavelengths (1295.56, 1300.05, 1304.58, and 1309.14 nm), reaching up to 10 km with a minimum optical link budget of 6.3 dB per IEEE 802.3ba.
The module uses EML (electro-absorption modulated laser) transmitters and PIN photodiode receivers, carrying four lanes at 25.78125 Gbps each for an aggregate 103.1 Gbps line rate. It supports 100G Ethernet (100GBASE-LR4) per IEEE 802.3ba. Digital diagnostic monitoring (DDM/DOM) provides real-time readings of TX/RX optical power, laser bias current, temperature, and supply voltage. The FTLC1156RDPL-1Y draws a maximum of 3.5 W from a single 3.3 V supply and operates from 0 to 70 °C.
As a QSFP28 MSA-compliant module, the FTLC1156RDPL-1Y is compatible with platforms that accept third-party optics, including Cisco Nexus and Catalyst, Juniper MX and QFX, Arista 7000 series, and others. All Finisar LR4 generations and ordering variants (FTLC1151RDPL, FTLC1154RDPL, FTLC1156RDPL, FTLC1156RDPL-1Y) share the same optical interface and are fully interoperable on the same fiber link.
The FTLC1156RDPL-1Y and FTLC1156RDPL share identical optical specifications: same wavelengths, same 6.3 dB link budget, same 10 km reach, and same 3.5 W power envelope. Our compatible module covers both part numbers. If your bill of materials specifies the -1Y variant, this is the correct replacement.
Our compatible FTLC1156RDPL-1Y is CE and RoHS certified, QSFP28 MSA-compliant, and conforms to IEEE 802.3ba. Before delivery, every module undergoes optical parameter measurement, connector cleanliness inspection, and EEPROM data validation testing.

Frequently Asked Questions
What does the -1Y suffix mean on FTLC1156RDPL-1Y?
The -1Y suffix is a catalog code in Coherent's (formerly Finisar/II-VI) ordering system. The FTLC1156RDPL and FTLC1156RDPL-1Y share the same 100GBASE-LR4 QSFP28 optical and electrical specifications. Our compatible version covers both part numbers.
Is FTLC1156RDPL-1Y the same as Coherent or II-VI FTLC1156RDPL-1Y?
Yes. Finisar was acquired by II-VI in 2019, and the combined company became Coherent Corp in 2022. The FTLC1156RDPL-1Y part number originated under the Finisar brand and continues in Coherent's catalog. Regardless of which brand name appears on your BOM, the specifications are the same.
Does FTLC1156RDPL-1Y work in Cisco, Arista, and Juniper equipment?
Our module is programmed with Finisar/Coherent EEPROM vendor identification and works in most equipment with standard QSFP28 ports. Some platforms may require a service command to allow third-party optics. We can also program the module with platform-specific coding on request.
