Finisar compatible FTLC1151SDPL Description
EdgeOptic's FTLC1151SDPL compatible is a Finisar/Coherent-coded multirate 100G QSFP28 transceiver, built on the same 100G-QSFP28-10 hardware platform we use across the LR4 family. The FTLC1151SDPL is the S-suffix multirate variant of Finisar's first-generation 100G QSFP28 LR4 line, and it is the page's reason for existing alongside the Ethernet-only FTLC1151RDPL and FTLC1154RDPL R-suffix siblings. 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/Coherent EEPROM vendor identification so it presents to the host platform as a genuine FTLC1151SDPL during inventory polling and DOM telemetry.
The S-suffix designation marks this module as multirate. It is widely documented as supporting three protocols on the same hardware: 100GBASE-LR4 per IEEE 802.3ba Clause 88 at 103.125 Gbps for Ethernet, OTN OTU4 4I1-9D1F at 111.81 Gbps for optical transport, and 128G Generation 6 Fiber Channel at 112.2 Gbps for SAN deployments. The R-suffix siblings (FTLC1151RDPL, FTLC1154RDPL) cover the Ethernet-only 100GBASE-LR4 case at 103.125 Gbps without OTU4 or 128GFC. If your deployment is OTU4 transport or 128GFC SAN, the SDPL is the variant to specify; if it is pure Ethernet, the RDPL siblings are the catalog match.
Optically the module aggregates 4x25.78125 Gbps NRZ lanes on Ethernet (or the protocol-equivalent line rates for OTU4 and 128GFC) onto LAN WDM channels at 1295.56, 1300.05, 1304.58 and 1309.14 nm. Transmission uses an EML laser array on the TX side and a PIN photodiode array on the RX side. The optical path loss budget is 6.3 dB, sufficient for 10 km of single-mode fiber including standard connector and splice losses. The host electrical interface follows the QSFP28 MSA 4-lane specification across all protocol modes; the host-side line rate and framing change per protocol (103.125 Gbps for 100GBASE-LR4 Ethernet, 111.81 Gbps for OTU4, 112.2 Gbps for 128GFC Gen 6).
QSFP28 MSA SFF-8665 and SFF-8636 management compliance covers the electrical and software interfaces. DDM/DOM telemetry exposes per-lane TX and RX optical power, module temperature, supply voltage and laser bias current. The duplex LC connector accepts standard SMF patch cords, and the commercial 0 to 70 °C operating temperature range covers typical central-office and data-center environments. The module is hot-pluggable and presents a Finisar/Coherent vendor string to host platforms that read EEPROM vendor identification.

Frequently Asked Questions
What is the difference between FTLC1151SDPL and FTLC1151RDPL?
The S-suffix and R-suffix mark different protocol coverage on the same physical hardware platform. The FTLC1151SDPL (S-suffix) is multirate: it is widely documented as supporting 100GBASE-LR4 Ethernet at 103.125 Gbps, OTN OTU4 4I1-9D1F at 111.81 Gbps and 128G Generation 6 Fiber Channel at 112.2 Gbps. The FTLC1151RDPL (R-suffix) is Ethernet-only 100GBASE-LR4 at 103.125 Gbps, without OTU4 or 128GFC support. Specify the SDPL when your deployment is OTU4 transport or 128GFC SAN; specify the RDPL when it is pure Ethernet.
Does the FTLC1151SDPL support 128G Fiber Channel?
Yes. The FTLC1151SDPL is widely documented as supporting 128G Generation 6 Fiber Channel at 112.2 Gbps alongside its 100GBASE-LR4 Ethernet and OTU4 modes. That triple-protocol capability is the SDPL's reason for existing alongside the Ethernet-only RDPL siblings, and it makes the module a fit for SAN environments that need 128GFC over the same QSFP28 form factor as 100G Ethernet.
Is there a newer generation of the FTLC1151SDPL?
Coherent's catalog also lists the FTLC1154SDPL, a related multirate 100G QSFP28 LR4 module that follows the same R/S-suffix convention. The exact functional difference between the FTLC1151 and FTLC1154 catalog numbers is not documented in any public Finisar/Coherent source we located, so we do not claim FTLC1154SDPL supersedes FTLC1151SDPL. Both part numbers are in active circulation under the Coherent brand. Order whichever catalog number your project documentation specifies.
Can I use the FTLC1151SDPL for Ethernet-only deployments?
Yes. The multirate capability is additive: the SDPL supports 100GBASE-LR4 per IEEE 802.3ba Clause 88 at 103.125 Gbps as one of its protocol modes, so it works as a drop-in for any pure 100G Ethernet link of 10 km or less over single-mode fiber. If the deployment is unambiguously Ethernet-only and does not need OTU4 or 128GFC, the FTLC1151RDPL or FTLC1154RDPL R-suffix siblings are the more cost-aligned catalog match; specify whichever code your project standard mandates.
