Finisar compatible FTLC1151RDPL Description
EdgeOptic's FTLC1151RDPL compatible is a Finisar/Coherent-coded 100GBASE-LR4 QSFP28 transceiver for 10 km links over G.652 single-mode fiber. The original FTLC1151RDPL was Finisar's first-generation 100G LR4 module; following Finisar's 2019 acquisition by II-VI and the 2022 rebrand to Coherent, the part number remains in active circulation across all three brand identities. Our compatible carries Finisar EEPROM vendor identification so it presents to host platforms as a genuine FTLC1151RDPL during inventory polling and DOM telemetry.
The module aggregates 4x25.78125 Gbps NRZ lanes into a 103.125 Gbps payload using LAN WDM at 1295.56, 1300.05, 1304.58 and 1309.14 nm per IEEE 802.3ba Clause 88. Transmission uses a DFB-based LAN-WDM EML array on the TX side and a PIN photodiode array on the RX side. TX power per lane is rated -4.3 to 4.5 dBm with RX sensitivity better than -10.6 dBm. Optical path loss budget is 6.3 dB per IEEE 802.3ba Clause 88, sufficient for 10 km of OS2 fiber including standard connector and splice losses. The host interface is CAUI-4 (4x25G NRZ); RS-FEC (IEEE 802.3bj Clause 91) is supported transparently when applied at the host MAC.
Power consumption is typically 3.5 W (Class 3 per SFF-8665) with a maximum of 4.5 W (Class 4 per SFF-8665). DOM and digital diagnostics follow the SFF-8636 management interface. Operating temperature is the commercial 0 to 70 C range. The module is hot-pluggable and uses an LC duplex receptacle, with certifications covering CE, RoHS-6, IEC 60825-1 Class 1 and FDA Class 1.
Within Coherent's catalog the FTLC1151RDPL sits as a 10 km LR4 alongside the FTLC1154RDPL, which is the catalog sibling at the same standard, form factor and wavelength plan. Both share the LAN WDM optical class. A separate FTLC1151RDPL-20 SKU exists for 20 km reach over SMF; it is a different product line, not a variant of the 10 km module. The Gen 2 derivative FTLC1151RDPL2 carries the same optical specifications under Coherent's revised naming convention.
MSA-compliant hosts that accept third-party EEPROM identification can typically use the module without per-platform configuration. For Cisco-, Arista-, Juniper-, or Dell-coded versions, contact our sales team for coding options. On Cisco NX-OS the module may require the 'service unsupported-transceiver' command because the EEPROM identifies as Finisar rather than Cisco. EdgeOptic can supply Cisco-coded, Arista-coded or Juniper-coded versions on request to remove that step.
The module ships CE/RoHS certified and complies with QSFP28 MSA SFF-8665 and IEEE 802.3ba 100GBASE-LR4. 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 or alternative vendor coding, contact our sales team.
Frequently Asked Questions
Is the FTLC1151RDPL still available now that Finisar is part of Coherent?
Yes. Finisar was acquired by II-VI in 2019, and II-VI rebranded to Coherent in 2022. The FTLC1151RDPL part number is unchanged across all three brand identities and continues in Coherent's networking portfolio. EdgeOptic's compatible mirrors the original Finisar optical and electrical specifications and presents Finisar/Coherent EEPROM vendor identification on the host.
How does the FTLC1151RDPL differ from the FTLC1154RDPL?
Both are Finisar/Coherent 100GBASE-LR4 QSFP28 modules in the same 10 km LAN WDM optical class with identical wavelength plans, LC duplex receptacles and SMF reach. They are catalog siblings within Coherent's LR4 portfolio rather than reach or wavelength variants. Choose whichever part number matches the SKU your procurement system or BoM specifies; the host-side behaviour and optical performance fall in the same envelope.
Does the FTLC1151RDPL work in Cisco, Arista and Juniper switches without extra CLI configuration?
EdgeOptic's standard FTLC1151RDPL compatible is Finisar/Coherent-coded. Cisco NX-OS may require the 'service unsupported-transceiver' command because the EEPROM does not identify as Cisco. EdgeOptic also supplies Cisco-coded, Arista-coded or Juniper-coded versions on request, which removes the need for any platform CLI workaround.
What is the difference between FTLC1151RDPL and FTLC1151RDPL2?
FTLC1151RDPL2 is the Gen 2 designation under Coherent's revised naming convention, applied to a manufacturing or firmware revision of the same 100GBASE-LR4 QSFP28 module class. The optical wavelengths, reach, fiber type and host interface match the original FTLC1151RDPL. EdgeOptic's compatible is fit-for-purpose against either revision; if your procurement system specifies the -2 suffix explicitly, mention it on the order and we will program the matching EEPROM string.
