Finisar compatible FTLC1156RDPL-1Y Description
EdgeOptic's FTLC1156RDPL-1Y compatible is a Coherent (formerly Finisar / II-VI) ordering-code-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. The -1Y suffix is a Coherent catalog code; DigiKey lists FTLC1156RDPL-1Y at a slightly higher tier than the base FTLC1156RDPL with identical functional specs across the listed parameters (103.1 Gbps, 1310 nm, QSFP28, LC, 100GBASE-LR4, 10 km); Coherent's public documentation does not define the suffix meaning explicitly. EdgeOptic codes the EEPROM separately for each suffix variant so the platform identifies the exact part number listed in the BOM.
The optical path uses LAN WDM with four channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, multiplexed onto a single duplex LC fiber pair. Each channel carries 25.78125 Gbps NRZ for an aggregate 103.1 Gbps line rate. Optical path loss budget is 6.3 dB per IEEE 802.3ba Clause 88, supporting up to 10 km over OS2 (G.652) single-mode fiber. Reach in the field depends on actual fiber attenuation and connector loss across the link.
Digital diagnostic monitoring (DDM/DOM) reports transmit and receive optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface, with vendor name, vendor part number, serial number, and date code exposed in the standard EEPROM identification fields. Host electrical interface is CAUI-4 (4x25G NRZ). Operating temperature is 0 to 70 degrees Celsius (commercial), supply voltage 3.3 V, typical power draw 3.5 W within the QSFP28 Class 4 cage budget of 4.5 W maximum per SFF-8665. Works on QSFP28-cage host platforms across vendor portfolios; refer to your host's QSFP28 transceiver compatibility list for the specific FTLC1156RDPL-1Y or family-equivalent entry.
The FTLC1156RDPL and FTLC1156RDPL-1Y share the same 100GBASE-LR4 optical interface and identical functional specifications. The module is CE and RoHS certified and complies with QSFP28 MSA SFF-8665 and IEEE 802.3ba 100GBASE-LR4. For other Finisar / Coherent FTLC1156 suffix variants, EEPROM coverage should be confirmed before ordering. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing, alternative vendor coding, or to confirm coverage of a different FTLC1156 suffix, contact our sales team.
Frequently Asked Questions
What does the -1Y suffix mean on FTLC1156RDPL-1Y?
The -1Y is a Coherent catalog ordering code. DigiKey lists FTLC1156RDPL-1Y at a slightly higher price tier than the base FTLC1156RDPL with identical functional specs (103.1 Gbps, 1310 nm, QSFP28, LC duplex, 100GBASE-LR4, 10 km). Coherent's public documentation does not explicitly define the suffix meaning. EdgeOptic codes the EEPROM separately for the -1Y variant so the platform identifies the exact part number specified in the BOM. If your equipment expects the base FTLC1156RDPL instead, contact our sales team for the matching coded compatible.
Is FTLC1156RDPL-1Y the same part under Finisar, II-VI, and Coherent branding?
Yes. Finisar was acquired by II-VI in September 2019, and II-VI rebranded to Coherent Corp in September 2022. The FTLC1156RDPL-1Y part number continues under the Coherent brand with unchanged optical specifications. Distributors list the same part under all three brand names depending on listing age, so a BOM specifying Finisar FTLC1156RDPL-1Y, II-VI FTLC1156RDPL-1Y, or Coherent FTLC1156RDPL-1Y refers to the same OEM module. EdgeOptic's compatible covers the part number across all three brand listings.
Does FTLC1156RDPL-1Y work in switches with third-party transceiver acceptance policies?
EdgeOptic codes the EEPROM with Coherent / Finisar FTLC1156RDPL-1Y vendor data, so QSFP28-cage hosts that recognize Coherent or Finisar optics identify the module as the OEM part, with no override or unsupported-transceiver command needed. The unsupported-transceiver workflow applies only when a host platform enforces host-vendor coding (for example, a Cisco switch requiring Cisco-coded EEPROM); in those cases, the correct path is to order a host-coded compatible rather than override. Contact our sales team to confirm the right coded variant for your switch vendor before purchasing.
